Answer:
6.45 feet
Step-by-step explanation:
He starts 17 and 1/2 feet off the ground
Elevation relative to ground: 17 1/2
Then he increases the height by 4 and 3/4
Expression: 17 1/2 +4 3/4
Elevation relative to ground: 22 1/4
Next he decreases the elevation by 15.8 feet
Expression: 22.25-15.8
Elevation relative to ground: 6.45
The answer 6.45 feet from the ground
Answer:
You will break even on the car wash when you buy 13.5 gallons. As long as you buy that or more, it is cheaper to get the car wash.
Step-by-step explanation:
In order to find this, we need to create equations for both situations. If we let x equal the amount of gallons purchased, we can model the first equation as:
f(x) = 3.35x
And the second equation as:
f(x) = 3.05x + 4.05
Then to find when they equal each other, we can set the two equations equal to each other and solve for x.
3.35x = 3.05x + 4.05
0.30x = 4.05
x = 13.5
This means once you buy 13.5 gallons, the prices will be the same. Any amount over that and the car wash will be cheaper
Answer:
15% discount means you're paying 85% of the marked price because total is 100% and 100-15 = 85%
Let X be the naked price
Paid = marked price - discount
Paid = X - (15/100 × X)
Using distribution property,
Paid = X(1 - 15/100)
Paid = X[(100-15)/100]
Paid = X(85/100)
Which is 85/100 × X
Hence 85% of X
If the area of one is 20, that the area of 30 is 20*30=600 square inches.
