Answer:
f(200) = 116
Step-by-step explanation:
Given the function f(x) = 90 + 0.13(x), and f(200), this means that you have to solve the function by plugging in 200 substituting the x, and solve,
f(200) = 90 + 0.13(200)
f(200) = 90 + 26
f(200) = 116
The f(200) represents the total cost in dollars when driving for 116 miles.
He cannot make a rectangle with those measurements because the base of the rectangle need to be a least more that 1cm bigger than the height other wise its just a square
<u>Answer:4.75</u>
<u>Since we don't have a total cost we will write an equation that will allow us to find the cost of x. The equation is 4x= 2x + $3 + $3.75 + $2.75. Now that we have our equation we are going to start by adding 3, 3.75, and 2.75. When added together, they come out with a total of 9.5. Now the equation becomes 4x= 2x + $9.50. Since we have our new equation we are going to subtract 2x from both sides of the equation. We now have the equation 2x= $9.50. Finally, you will divide both sides by 2. This leaves us with the final outcome x= $4.75. This means that one glues stick cost $4.75. Let's check by substituting $4.75 as the value of x in the expressions 4x is Carlo's total and 2x + $3 + $3.75 + $2.75 is Helen's total. First we do 4x, 4 multiplied by 4.75 equals 19, so Carlo spent $19 on art supplies. Now we do 2x + $3 + $3.75 + $2.75, which is 9.5 added to 9.5 and equals 19. So Helen spent $19 on art supplies. This proves that the cost of one glue stick, x, is equal $4.75.</u>

Answer:
A
Step-by-step explanation:
Joint variation is given by:
Where k is some constant.
We are given that y = 360 when x = 4 and z = 10. Therefore:
Solving for k:
Therefore, our equation is:
Then when x = 5 and z = 12:
The answer is A.
38% of 21,515,714 is 8175971.32 which can be rounded to 8,175,971.
