Answer:
a) 740 × 233 = 172420
In the number 740, there's an zero being added so the answer will have a zero too.
b) 74 x 2.33 = 172.42
In the number 2.33, the decimal place is two to the left so the answer needs to have a decimal that is to to the left.

What is an equation of the line that passes through the points (-6,3) and (-5,2)
Answer:
y=-x-3
Step-by-step explanation:
Hi there!
We want to find the equation of the line that passes through the points (-6,3) and (-5,2)
There are 3 ways to write the equation of the line:
Slope-intercept form, which is y=mx+b, where m is the slope and b is the y interceptPoint-slope form, which is [tex]y-y_1=m(x-x_1)[/tex], where m is the slope and [tex](x_1, y_1)[/tex] is a pointStandard form, which is ax+by=c, where a, b, and c are free integer coefficients, but a and b cannot be equal to zero, and a cannot be negativeThe most common way to write the equation of the line is in slope-intercept form, so let's do it that way.
First, we'll need to find the slope of the line
The formula for the slope calculated from 2 points is [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are points
Although we already have 2 points, let's label their values in order to avoid confusion later:
[tex]x_1= -6\\y_1=3\\x_2=-5\\y_2=2[/tex]
Now substitute these values into the formula to find slope (m):
m=[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Substitute (remember: we have NEGATIVE numbers, but the formula calls for SUBTRACTION, so we'll end up subtracting a negative):
m=[tex]\frac{2-3}{-5--6}[/tex]
Simplify:
m=[tex]\frac{2-3}{-5+6}[/tex]
Add/subtract the numbers together:
m=[tex]\frac{-1}{1}[/tex]
Divide
m=-1
We can substitute this as m in y=mx+b:
y=-1x+b, or y=-x+b
We need to find b now
Since the equation passes through both (-6, 3) and (-5, 2), we can use either point to solve for b
Taking (-6, 3) for example:
Substitute -6 as x and 3 as y
3=-1(-6)+b
Multiply
3=6+b
Subtract 6 from both sides
-3=b
Substitute -3 as b into the equation
y=-x-3
Hope this helps!
Find the following for the nth term of the following geometric sequence, as an expression of n:
3, 15, 75, 375
Answer:
[tex]15^{n-1}[/tex]
Step-by-step explanation:
First , Let's find the common ratio of this sequence.
[tex]\frac{15}{3}=5\\\frac{75}{15} = 5\\\frac{375}{75} = 5[/tex]
SO,
r = 5
Now let's use this formula to find the n th term
[tex]T_n = ar^{n-1}[/tex]
Here,
a = first term
r = common ratio
Let's find,
[tex]T_n = 3*5^{n-1}[/tex]
[tex]T_n =15^{n-1}[/tex]
Therefore,
the n th term is,
[tex]15^{n-1}[/tex]
Hope this helps you.
Let me know if you have any other questions :-)
Answer:
[tex]a_{n}[/tex] = 3[tex](5)^{n-1}[/tex]
Step-by-step explanation:
There is a common ratio between consecutive terms , that is
15 ÷ 3 = 75 ÷ 15 = 375 ÷ 75 = 5
This indicates the sequence is geometric with nth term
[tex]a_{n}[/tex] = a₁ [tex](r)^{n-1}[/tex]
where a₁ is the first term and r the common ratio
Here a₁ = 3 and r = 5 , then
[tex]a_{n}[/tex] = 3 [tex](5)^{n-1}[/tex]

10x + 8 = 3(x – 2)
10x + 8 = 3x
Answer:
dfq
Step-by-step explanation:
1.
10x + 8 = 3(x – 2)
10x + 8 = 3x - 6
10x - 3x = -8 -6
7x = -14
x = -14/7
x = -2
2.
10x + 8 = 3x
10x - 3x = -8
7x = - 8
x = -8/7

Answer:
$400
Step-by-step explanation:
If college costs $7,500 per year, and she's going to go for 4 years, then she needs to save 4 x $7,500 = $30,000 total. From the table, she would need to deposit $400 per month in order to have $31,667 in time for college.
Answer: $200
Step-by-step explanation:
Because in the table the minimum number is in the month when she save $200.
Initial balance is $5000
Account in value in five years is $18,737
Find the probability that the sum of two randomly chosen numbers from the set {0, 1, 2, 3, 4, 5, 6, 7, 8, 9} is no greater than 10.
Using it's concept, it is found that there is a 0.64 = 64% probability that the sum of two randomly chosen numbers from the set {0, 1, 2, 3, 4, 5, 6, 7, 8, 9} is no greater than 10.
A probability is the number of desired outcomes divided by the number of total outcomes.
In this problem:
Two numbers that can be repeated chosen from a set of 10 numbers, thus, in total, there are [tex]10^2 = 100[/tex] outcomes.For a sum no greater than 10, we have that:
0 can be added with all the 10 numbers, as can 1.2 can be added with 9 of them, bar 9.3 can be added with 8 of them.4 can be added with 7 of them.5 can be added with 6 of them.6 can be added with 5 numbers, 7 with 4, 8 with 3, and 9 with 2.Hence, the number of desired outcomes is:
[tex]D = 10(2) + 9 + 8 + 7 + 6 + 5 + 4 + 3 + 2 = 64[/tex]
The probability is:
[tex]p = \frac{D}{T} = \frac{64}{100} = 0.64[/tex]
0.64 = 64% probability that the sum of two randomly chosen numbers from the set {0, 1, 2, 3, 4, 5, 6, 7, 8, 9} is no greater than 10.

Find the equation of the straight line passing through the point (3,5) which is perpendicular to the line y=3x+2
Answer:
the desired equation is y = (-1/3)x + 6
Step-by-step explanation:
Let the given line be A: y=3x+2
The slope of line A is m = 3.
The slope of any line B which is perpendicular to line A is the negative reciprocal of the slope of A: m = -(1/3).
The particular perpendicular line that passes through (3, 5) is then
5 = (-1/3)(3) + b, which simplifies to 5 = -1 + b, or b = 6.
Thus, the desired equation is y = (-1/3)x + 6

Answer:
"O c. 17.156"
Step-by-step explanation:
A is not a rational number because it cannot be written as a fraction [with two integers] or an integer (the square root of 15 is equal too 3.87298334...)
B is not a rational number because it also goes on forever, just like A.
C is a rational number because it does not go on forever.

What is the slope of the line that passes through the points (-6,-7) and (-25, -7)
Answer:
slope is 0
Step-by-step explanation:
(-6,-7) and (-25, -7)
To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁)
Plug in these values:
(-7 - (-7) / (-25 - (-6))
Simplify the parentheses.
= (-7 + 7) / (-25 + 6)
= (0) / (-19)
Simplify the fraction.
= 0/-19
= 0
This is your slope.
This means your line is a horizontal line.

Answer = [?]ft^2 (Acellus!)
Answer:
3042
Step-by-step explanation:
1/2 * 81 * 81 * sin(112) = 3041.6266
The area of the triangular gable is 6083.25 ft².
What is a triangle?A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.
We know the area of a triangle with two sides a and b and angle C is,
(a×b×sinC).
Given, A painter is painting the gable end of a house which is a triangle with two sides of 81 feet that meet at a 112° angle.
∴ The area of the triangular gable is = (81×81×sin112°).
= (81)²sin112°.
= (81)²×0.928 ft².
= 6083.25 ft².

(18.85 minutes)
Mary can allocate to each chore around 18.85 minutes.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
It is given that Mary has 2 1/5 hours before she needs to meet her friend. She needs to take care of 7 chores before then.
Hence, we get
2 and 1/5 hours = 132 minutes (120 + 12)
