Quiana took out a loan to pay for a new car. Initially she owned the lender $15,234.68. She has repaid $247.43 of the loan each month for the past 5 months. What is the net changed to the loan from Quiana's perspective over the past 5 months?
Answer:
[tex]Net\ Change = \$13997.53[/tex]
Step-by-step explanation:
Given
[tex]Debt = \$15,234.68[/tex]
[tex]Monthly\ Payment= \$247.43[/tex]
[tex]Duration = 5\ months[/tex]
Required
Determine the net change
First, we need to determine the total repaid amount;
[tex]Amount = Monthly\ Payment * Duration[/tex]
Substitute values for Monthly Payment and Duration
[tex]Amount = \$247.43 * 5[/tex]
[tex]Amount = \$1237.15[/tex]
The net change is the difference between the loan amount and the repaid amount
[tex]Net\ Change = Loan\ Amount - Repaid\ Amount[/tex]
[tex]Net\ Change = \$15,234.68 - \$1237.15[/tex]
[tex]Net\ Change = \$13997.53[/tex]
Hence, the net change over the period of 5 months is $13997.53
Answer: Quiana's initial loan amount is -15, 234.68. This is the total amount of money she must pay back to the lender.
How many bicycles and how many skateboards are in the shop? Show your work.
Answer:75
Step-by-step explanation:54+21
Answer:
15 bicycles, 6 skateboards
Step-by-step explanation:
We are looking for the number of skateboards and the number of bicycles. Those two numbers are our unknowns.
We define variables for those two numbers.
Let s = number of skateboards.
Let b = number of bicycles.
A skateboard has 4 wheels. s number of skateboards have 4s wheels.
A bicycle has 2 wheels. b bicycles have 2b wheels.
The total number of wheels is 4s + 2b.
The total number of wheels is 54, so our first equation is
4s + 2b = 54
The total number of skateboards and bicycles combined is s + b.
We are told the total number of skateboards and bicycles combined is 21.
The second equation is
s + b = 21
We have a system of two equations in two unknowns.
4s + 2b = 54
s + b = 21
We can solve it by the elimination method.
Rewrite the first equation below.
Multiply both sides of the second equation by 2 and write it below that. Then add the equations.
4s + 2b = 54
(+) -2s - 2b = -42
-----------------------------
2s = 12
s = 6
There are 6 skateboards.
Now we substitute 6 for s in the second original equation and solve for b.
s + b = 21
6 + b = 21
b = 15
There are 15 bicycles.
Answer: 15 bicycles, 6 skateboards

Consider the perfect square trinomial identity:
a2 + 2ab + b2 = (a + b)2.
For the polynomial x2 + 10x + 25,
and b =
a =
Answer:
a = x
b = 5
Step-by-step explanation:
for the polynomial x² + 10x + 25, b = 5 and a = x.
In the polynomial x² + 10x + 25, we can observe that the first term, x², is the square of x, and the last term, 25, is the square of 5. This suggests that the polynomial follows the perfect square trinomial identity.
The middle term, 10x, can be rewritten as 2ab, where a represents x and b represents a term that when squared equals the last term, 25.
In this case, b = 5, because 5² = 25.
To find a, we can take the square root of the first term, x². The square root of x² is x, so a = x.
Therefore, for the polynomial x² + 10x + 25, b = 5 and a = x.

The Springfield Meteorological Center wanted to determine the accuracy of their weather forecasts. They
searched their records for those days when the forecaster had reported a 70% chance of rain. They
compared these forecasts to records of whether or not it actually rained on those particular days. The
forecast of 70% chance of rain can be considered very accurate if it rained on:
A. 95% to 100% of those days.
B. 85% to 94% of those days.
C. 75% to 84% of those days.
D. 65% to 74% of those days.
E
55% to 64% of those days.
Answer:
The correct option is;
D. 65% to 74%
Step-by-step explanation:
The accuracy of a forecast given based on a percentage or proportion or likelihood is determined by the based on the prevalence of the forecast in a similar proportion over the range of data points in which the forecast is made
Therefore, if it actually rained on 70% of those days for which the forecast was made, the forecast can be said to be very accurate.
Which is to say that the forecast of 70% chance of rain can be considered very accurate if it rained on 65 to 74% of those days which is in the range of the forecasted 70%.

A certain composite number has 4 factors and the sum of them is 96. Find the number(hint the number is divisible by 7). Just don't give me the answer by guessing. show me how you arrived at the solution elaborately i.e. show me your working in detail
Answer:
[tex]\huge\boxed{77}[/tex]
Step-by-step explanation:
The number can be divisible by 7.
The multiples of 7 are 7,14,21,28,35,42,49,56,63,70,77,84 and so on
Finding the factors for all of the multiples of 7:
7 => 1,7 [Not 4 factors]
14 => 1,2,7,14 [4 factors but Sum = 24]
21 => 1,3,7,21 [4 factors but Sum = 32]
28 => 1, 2, 4, 7, 14, 28 [Not 4]
35 => 1,5,7,35 [4 factors but Sum = 48]
42 => 1, 2, 3, 6, 7, 14, 21, 42 [Not 4]
49 => 1,7,49 [Not 4]
56 => 1, 2, 4, 7, 8, 14, 28, 56 [Not 4]
63 => 1, 3, 7, 9, 21, 63 [Not 4]
70 => 1, 2, 5, 7, 10, 14, 35, 70 [Not 4]
77 => 1, 7, 11, 77 [4 factors and Sum = 96]
Answer:
77
Step-by-step explanation:
The first factor is 1
Since it is divisible by 7, 7 will also be one of its factors.
Therefore the four factors are
1, 7, x, y
When x and y are integers
Using the following law...
The product of factors of a number in the same position (left or right) (increasing or decreasing order) is equal to the number
Counting from left
y is the first factor
x is the second factor
Counting from the right
1 is the first factor
7 is the second factor
Applying the last
y×1=x×7
y = 7x
the sum of the factors is 96
1+7+x+7x = 96
8x+8=96
8x = 88
x= 11
Hence the number is
7x = 7(11)
=77

Answer: Yes, Substitution property is the correct option.
Step-by-step explanation:
Substitution property of equality says that if 'a= b', then 'a' can be substituted in for 'b' in any equation, and 'b' can be substituted for 'a' in any equation.Given: m∠A+m∠B =70° ...(i), m∠X=m∠A
Then, substitute m∠X for m∠A in (i) , we get
m∠X+m∠B =70°
So, the correct option is "Substitution property"
IM STUMPED I USUALLY LOVE THESE PROBLEMS :( The least common multiple of x, 10 and 14 is 70. What is the greatest possible value of x?
Answer:
[tex]x=70[/tex]
Step-by-step explanation:
If we know that the LCM of 10, 14 and x will be 70, that means x has to be a factor of 70.
First, let's find the multiples of 10 and 14 until they equal 70.
[tex]10: 10,20,30,40,50,60,70[/tex]
[tex]14:14,28,42,56,70[/tex]
Since we're asking for the greatest value of x, that means that x has to be smaller or equal to than 70 but still large enough to be the greatest.
Hey, isn't 70 a factor of 70? The remainder gets to 1 which is a whole number, so 70 is a multiple of 70.
So, [tex]x = 70[/tex].

A student who is 5 1/4 feet tall has a shadow that is 2 feet and 10 1/2 inches long. At the same time. a flag pole has a shadow that is 10 1/2 feel long. How tall, to the nearest inch, is the flag pole?
Answer:
The height of the flag pole is approximately 19 feet and 2 inches.
Step-by-step explanation:
Let suppose that length of the shadow of the object is directly proportional to its height. Hence:
[tex]l \propto h[/tex]
[tex]l = k\cdot h[/tex]
Where:
[tex]h[/tex] - Height of the object, measured in inches.
[tex]l[/tex] - Shadow length of the object, measured in inches.
[tex]k[/tex] - Proportionality constant, dimensionless.
Now, let is find the value of the proportionality constant: ([tex]h = 5\,\frac{1}{4} \,ft[/tex] and [tex]l = 2\,ft\,\,10\,\frac{1}{2}\,in[/tex])
[tex]h = \frac{21}{4}\,ft[/tex]
[tex]h = \left(\frac{21}{4}\,ft \right)\cdot \left(12\,\frac{in}{ft} \right)[/tex]
[tex]h = 63\,in[/tex]
[tex]l = (2\,ft)\cdot \left(12\,\frac{in}{ft} \right) + \frac{21}{2}\,in[/tex]
[tex]l = 24\,in + \frac{21}{2}\,in[/tex]
[tex]l = \frac{48}{2}\,in+\frac{21}{2}\,in[/tex]
[tex]l = \frac{69}{2}\,in[/tex]
Then,
[tex]k = \frac{l}{h}[/tex]
[tex]k = \frac{\frac{69}{2}\,in }{63\,in}[/tex]
[tex]k = \frac{69}{126}[/tex]
[tex]k = \frac{23}{42}[/tex]
The equation is represented by [tex]l = \frac{23}{42}\cdot h[/tex]. If [tex]l = 10\,\frac{1}{2}\,ft[/tex], then:
[tex]l = \frac{21}{2}\,ft[/tex]
[tex]l = \left(\frac{21}{2}\,ft \right)\cdot \left(12\,\frac{in}{ft} \right)[/tex]
[tex]l = 126\,in[/tex]
The height of the flag pole is: ([tex]l = 126\,in[/tex], [tex]k = \frac{23}{42}[/tex])
[tex]h = \frac{l}{k}[/tex]
[tex]h = \frac{126\,in}{\frac{23}{42} }[/tex]
[tex]h = \frac{5292}{23}\,in[/tex]
[tex]h = 230\,\frac{2}{23}\,in[/tex]
[tex]h = \frac{115}{6}\,ft\,\frac{2}{23}\,in[/tex]
[tex]h = 19\,\frac{1}{6}\,ft \,\frac{2}{23}\,in[/tex]
[tex]h = 19\,ft\,\,2\,\frac{2}{23}\,in[/tex]
[tex]h = 19\,ft\,\,2\,in[/tex]
The height of the flag pole is approximately 19 feet and 2 inches.

Murphy purchases two bags of rice of weights 56 kg and 72 kg. Find the maximum value of weight which can measure the weight of the rice exact number of times.
Answer:
8
Step-by-step explanation:
In order to answer this question we need to find the greatest common divisor of the two quantities which will give us the maximum number by which both can be divided.
The greatest common divisor of a group of integers is the largest common divisor that divides each of the integers. The first step to find it is write down the integers as a product of primes, so we have:
[tex]56=(28)(2)=(14)(2)(2)=(7)(2)(2)(2)= 2^3[/tex]·[tex]7[/tex]
[tex]72=(24)(3)=8(3)(3)=2^3[/tex]·[tex]3^2[/tex]
Now, in order to find the gcd we are going to take the factors that they have in common. In this case they both share the [tex]2^3[/tex].
Thus, [tex]2^3=8[/tex] is the greatest common divisor and therefore the maximum value of weight which can measure the weight of the rice exact number of times.

Answer:

Step-by-step explanation:
In general
Given
y = f(x) then y = f(Cx) is a horizontal stretch/ compression in the x- direction
• If C > 1 then compression
• If 0 < C < 1 then stretch
Consider corresponding points on the 2 graphs
(2, 2 ) → (4, 2 )
(4, - 2 ) → (8, - 2 )
Indicating a stretch in the x- direction.
y = f([tex]\frac{x}{2}[/tex] ) with C = [tex]\frac{1}{2}[/tex] , that is 0 < C < 1
stretches the graph in the x- direction by a factor of 2
Thus
y = f([tex]\frac{x}{2}[/tex] ) → b
Freddy the frog is climbing up a well. Every day he climbs up 3 m but some nights he falls asleep and slips back 4m at the start of the 16th day he has climbed a total of 29 m. On how many nights was he asleep?
Answer: The frog fell asleep for 4 nights.
Step-by-step explanation: First, he climbs up 3m every night. there are 16 nights before he gets to 29m. He has not climbed up for the 16th day so 15*3= 45. 45-29= 16. 16/4=4. The frog slept for 4 nights.

Select the equations of the lines that are parallel to the line whose equation is y= 3x +5.
-3x + y = 8
3y = 9x
y=- jx
16x + 2y = 12
Answer:
-3x + y = 8.
3y = 9x.
Step-by-step explanation:
To find the slope of the lines we convert to slope-intercept form, which is
y = mx + c (m is the slope.)
The slope of y = 3x + 5 is therefore 3.
Parallel lines have the same slope.
Finding the slope of the given lines:
-3x + y = 8
y = 3x + 8 - slope is 3 so this is parallel to y = 3x + 5.
3y = 9x
Divide through by 3:
y = 3x - so this is also parallel to 3x + 5.
y = -jx The slope is -j so it is not parallel.
16x + 2y = 12
2y = -16x + 12
y = -8x + 6 - Not parallel.
The term to term rule of a sequence is "multiply by 3 and add 1". The third term is 13. Work out the first term of the sequence.
Answer:
The first term is 1
Step-by-step explanation:
The forward term to term rule is "multiply by 3 and add 1"
The backward rule is therefore
"subtract 1, then divide by three"
Apply the backward rule twice to go from 3rd to first term:
(13-1)/3 = 4
(4-1)/3 = 1
The first term is 1
Answer:
a_1 = 1
Step-by-step explanation:
your sequence is a_n = a_(n-1) * 3 + 1
if your 3rd one is 13 then:
a_3 = a_2 * 3 + 1 = (a_1 * 3 + 1) *3 + 1
13 = 9_a1 + 3 + 1
9 = 9*a_1
a_1 = 1 :)
why is gravitational force between two object usually unnoticeable
Answer:
gravitational attraction is based upon mass.More the mass more the force.When the object is as big as a moon it has a very less gravity.When we are talking about small objects like 2 pencils the force exists but is so weak that no noticabke movement takes place
Answer:
To notice that force, the objects have to have a big mass and be close to each others.
Generally in eveydays life, you don't notice this force since it is weak but that doesn't mean it does't exist.
If you go the space, you can notice this force since planets have big mass. If you get close to the gravitational field of a planet, you will feel a force that is pulling you toward the planet.

Positive numbers are not closed under subtraction. Give an example of this 1
below.
Answer:
5 -3 = 2
3-5 = -2
Step-by-step explanation:
In this question, we want to examine the validity of the statement by the use of an example.
Firstly, we need to understand the meaning of the fact that they are ‘closed’
By saying these numbers are closed under this arithmetic operation i.e subtraction, we directly mean that they obey the closure property.
Now, to obey the closure property means that if we move either way i.e by switching the numbers and performing the same arithmetic operation of subtraction, we are supposed to get same answer.
What this means in terms of examples is as follows;
Consider two positive numbers, 5 and 3
Now we know that 5-3 = 2
To check if the closure property is obeyed, switch the place of the numbers.
This means we would have;
3-5 = -2
We can see that both results are not the same. We can then conclude that the arithmetic operation of subtraction is not closed or does not obey the closure property for positive numbers.
Your baseball team has won 6 games and lost 4 games. If the team
does not lose any more games, how many games must the team win
to have a win : loss ratio of 2:1? Explain your answer.
Answer:
two games must be won by the team
Step-by-step explanation:
Let the no. of games played by x, since team
does not lose any more games.
Then total game won = 6+x
total game lost = 4
win: loss = 6+x : 4
given ratio of win and loss = 2:1
6+x : 4 = 2: 1
6+x = 8
=> x = 8-6 = 2
Thus, two games must be won by the team
then total win will be = 6+2 = 8
and loss = 4
ration of win : loss = 8:4 = 2:1

4x - 9 = -8
4x = 1
x = 1/4
Answer:
x= 0.25, or x=1/4
Step-by-step explanation:
First, use the distributive property and multiply 7 within the parenthesis:
7x -21
Next, use the distributive property again, and multiply 3 within the parenthesis:
12 -3x
Combine Like terms: 7x - 21 + 12 - 3x
4x - 9
Add 9 to both sides: 4x - 9 = -8
-8 + 9 = 1
Divide 4 by both sides: 4x = 1
1 / 4 = .25 or 1/4

Answer:
B, C, A.
Step-by-step explanation:
A = C + 3A = C + 3
A = C + 3
A = C + 3A
C + 3A = C + 3
3A = 3
A = 1
A = C + 3
1 = C + 3
C + 3 = 1
C = -2
B = 2C
B = 2(-2)
B = -4.
So, from least to greatest, B = -4, C = -2, and A = 1.
