Answer:
12(j+t) + 15 = c
Step-by-step explanation:
So, lets go over what we know.
First off, for simplicity, lets consider Johnathan as J, and Trina as T.
We know that both J and T produce 12 dollars each per hour.
We know that J gets a extra 15 dollars.
We can think of the amount they produce each hour as the time they work in total, times the money they make a hour, which is 12.
We can think of this first part where the total time they work is (J + T)
The 12 dollars they get an hour can be though of as multiplying this sum: 12(J+T)
Finally, we know that J gets an extra 15 dollars.
This is not dependent on time, like the other variables, so we simply add it to the sum of what they make in the end:
12(J+T)+15
This looks like answer C.
Answer:
C

How many solutions can be found for the system of linear equations represented on the graph?
A) no solution
B) one solution
C) two solutions
D) infinitely many solutions
Answer:
A) no solution
Step-by-step explanation:
These lines are parallel. Which means that they will never intersect, and since the solution to a system of equations is the point or points of intersection, this means there would be no solution to this system.
Tory creates a cell phone app. He wants to distribute it through a company that will pay him $100 plus $0.25 every time the app, x is downloaded. In the first month he made $380.
The equation that can be used to determine how many times the app, x, was downloaded is
The app was downloaded 1120 times for Tory to earn $380.
A linear equation is in the form:
y = mx + b;
where y, x are variables, m is the rate of change and b is the initial value of y.
Let y represent the total money paid to download the app x times.
The company pay him $100 plus $0.25 every time the app is downloaded. hence b = 100, m = 0.25
y = 0.25x + 100
For making 380:
380 = 0.25x + 100
280 = 0.25x
x = 1120
Therefore the app was downloaded 1120 times for Tory to earn $380.

If 20% of a number is 28 and 25% of the same number is 35, find 45% of that number.If 7% of a number equals 9, find 70% of that number.
Answer:
Step-by-step explanation:
Let the number be 'x'
20% * x = 28
[tex]\dfrac{20}{100}*x = 28\\\\\\\dfrac{1}{5}*x=28\\\\\\x=28*5\\\\x = 140[/tex]
[tex]\dfrac{45}{100}*140=9*7=63[/tex]
45% of 140 = 63
2)
[tex]\dfrac{7}{100}*y=9\\\\y=9*\dfrac{100}{7}=\dfrac{900}{7}=128.57[/tex]
[tex]\dfrac{70}{100}*128.57= 90[/tex]
for a field trip the school bought 47 sandwiches for $4.60 each and 39 bags of chips for $1.25 each.How much did the school spend in all?
Answer: To get to your final sum you will have to calculate the sum of both items: the sandwiches and the chips. Then you will get the total sum of all what they spend.
Step 1:
Sum of one sandwich= 4.60 dollar
sum of 47 sandwiches= 47×4.60 =216.2dollars
Step 2:
Sum of one chip=1.25 dollar
sum of 39 bags of chips=39×1.25= 48.75dollars
step 3: sum up the sum of sandwiches and that of the chips
216.2 + 48.75 =264.95dollars

Answer:
CD = 30.43; LK = 14.08
Step-by-step explanation:
Problem 12.
Let's first find BD. Triangle ADB is a right triangle with hypotenuse AB. By definition of sine ( or by theorem, they're equivalent) [tex]{BD \over 20} = sin 54.[/tex], hence BD= 16.18. Jump on the other side now. Triangle BDC is a right triangle with sides BD and CD. By definition of tangent [tex] {{16.18} \over CD} = tan 28 [/tex], thus CD= 30.43.
Problem 13
Assuming the 72° is angle JLK
As usual, triangle MJL is a right triangle with sides MJ and LJ. By definition of tangent [tex] {{JL} \over 14} = tan 51 [/tex]. Follows that JL = 14.81. Now, similarly, trinagle JLK is a right triangle, with hypotenuse JL. From the definition of sine, as before,[tex]{KL \over 14.81} = sin 72.[/tex]. Solving for the only unknown value, you find LK = 14.08.

Miguel's mother builds and sells houses. She wants to buy a piece of land on which to build several houses. There are two lots for sale. One is a rectangular plot that is 3/8 of a mile by 2/3 of a mile. The other square plot that is 2/5 of a mile.
Part A
Which lot should Miguel's mother buy if she wants the biggest lot?
Part B
If the land in the area sells for 750,000 a square mile, how much should she expect to pay?
Answer:
Square lot and 187500
Step-by-step explanation:
To find question number A, we can calculate the area of each lot. The square plot is:
2/5×2/5=4/25
The first one is
2/3×3/8=1/4
Then we can make both have the same denominator:
1/4=25/100, 4/25=16/100
That means that the square lot is bigger.
We know that the area is 1/4 square mile. So it's 1/4 of 750,000
That's
1/4×750000=187500

What is 7/8 divided by 2/8
Answer:
7/8 ÷ 2/8 = 3 1/2
Step-by-step explanation:
When we divide two fractions, such as 7/8 ÷ 2/8, we flip the second fraction and then we simply multiply the numerators with each other and the denominator with each other.
The quotient obtained from the division of given fractions is 7/2.
Given that, 7/8 divided by 2/8.
Dividing fractions is nothing but multiplying the fractions by reversing one of the two fraction numbers or by writing the reciprocal of one of the fractions. By reciprocal we mean, that if a fraction is given as a/b, then the reciprocal of it will b/a.
Here, 7/8 ÷ 2/8
= 7/8 × 8/2
= 7/2
Therefore, the quotient obtained from the division of given fractions is 7/2.

Answer:
a = 10
d = 5
Step-by-step explanation:
[tex]a_{n}=a + (n-1)d\\\\a_{5}=30\\\\a + (5-1)*d=30\\\\[/tex]
a + 4d = 30 ------------------(I)
[tex]a_{13}=70\\\\a + (13-1)d=70[/tex]
a + 12d =70 -------------(II)
Multiply equation (II) by (-1) and then add.So, 'a' will be eliminated and you can find the value of d
(I) a + 4d = 30
(II)*(-1) -a - 12d = -70 {Now add}
- 8d = - 40
Divide both sides by (-8)
d = -40/-8
d = 5
Plugin d = 5 in equation (I)
a + 4*5 = 30
a + 20 = 30
a = 30 - 20
a = 10
A tractor can plant a field at a rate of 2.5 acres per 5 minutes. If a mammoth farm measuring 4 square miles needs planting, how long will it take in hours to plant the field? There are 640 acres in a square mile. Determine your answer to the nearest hour. If the tractor can run 8 hours a day, what is the minimum number of days it will take to plant the farm?
The time taken by the tractor to plant the field with an area of 4 square miles is nearly 85 hours.
The minimum number of days taken by the tractor when working 8 hours a day is 11 days.
What is the area?The area is the total surface occupied within the boundary of the figure.
How to solve the question?In the question, we are given that a tractor can plant a field at a rate of 2.5 acres per 5 minutes.
We are asked the time taken by the tractor to plant a field having an area of 4 square miles.
First, we convert the area of the field from sq. miles to acres using the conversion rate, 1 square mile = 640 acres,
Thus, the area of the field = 4 sq. miles = 4*640 acres = 2560 acres.
Time taken to plant 2.5 acres is given to be 5 minutes.
Thus, the time taken to plan 1 acre = 5/2.5 = 2 minutes.
Thus, the time taken to plant the field having an area of 2560 acres = 2560*2 minutes = 5120 minutes = 85.33 hours = 85 hours and 20 minutes.
Thus, the time taken by the tractor to plant the field with an area of 4 square miles is nearly 85 hours.
The time for which the tractor can run daily is 8 hours.
Thus, the number of days taken by the tractor to plant the field = 85.33/8 = 10.66625, or 11 days.
Thus, the minimum number of days taken by the tractor when working 8 hours a day is 11 days.

3. Physics students were modeling the height of a ball once it was dropped from the roof of a 25 story
building. The students found that the height in feet, h, of the ball above the ground as a function of the
number of seconds, i, since it was dropped was given by h(t)= 300 - 1612.
From what height was the ball dropped?
To the nearest tenth of a second, determine the time at
which the ball hits the ground. Provide evidence from a
table to support your answer or solve this algebraically
if you recall how to.
It will take 4.3 seconds for the ball to hit the ground
Given the eqation of the height at which the object dropped expressed as
h(t) = 300 - 16t²
The object will hit the ground at when h(t) = 0
Substitute h(t) = 0 into the expression to have;
0 = 300 - 16t²
16t² = 300
t² = 300/16
t² = 18.75
t = 4.33sec
This shows that it will take 4.3 seconds for the ball to hit the ground
