Y = .7x + 29
x = miles driven and, y = total cost of renting the truck
Try this, pls:
When any line on graph is moved to the right, for 'x' must be '-'.
When one is moved down, for 'y' must be '-'.
Finaly: y=4(x-5)²-18.
Answer: A.
Ew, mental math... so basically, we would estimate the washing dishes to 20 minutes, and cleaning 40 min,
together 20+40 min
is 60 minutes, aprox 1 hour
Shelly spent almost 1 hour cleaning
Answer:
A. If Frank is on the toll road for 8.00 miles and then leaves the lane, how much will he have to pay total for the trip?
B. Each day, Susan has to pay a toll of $10.00 when she uses the toll lane to get to school. How many miles does Susan travel on the toll lane to get to school?
C. John started a carpool with his coworkers to save money. He and his three passengers split the cost of the toll. If each person pays about $2.31 (which includes their contribution to the toll lane entry fee), how many miles do they travel on the toll lane?
Step-by-step explanation:
the toll lane charges $0.25 fixed plus $0.75 per mile driven: fee = $0.25 + $0.75miles
a) Frank ⇒ $0.25 + (8 x $0.75) = $6.25
b) Susan ⇒ $10 - $0.25 = $9.75 / 0.75 = 13 miles
c) John ⇒ $2.31 x 3 = $6.93 - $0.25 = $6.68 / 0.75 = 8.91 ≈ 9 miles. Each passenger should pay $2.33 because the total toll lane fee is $7.
Using proportions, it is found that Student 2 is correct, as 37.6/0.1 = 376.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
One tenth is worth 0.1. How many tenths are there in 37.6? The division is given as follows:
37.6/0.1 = 376.
Hence student 2 is correct, as there are 376 tenths in 37.6.
