The best estimate is $1.97 per gallon
Step-by-step explanation:
Take the Cost- 39.95 then divide it by the gallons- 20.3 this gives you the price per gallon
Radius times 2 = diameter which would be 10 times 3.14 is 31.4 so it’s 31.4
Answer:
D
Step-by-step explanation:
So we have the expression:

First, simplify. Two negatives make a positive. Therefore, the -(-7) turns into +7:

When adding on the number line, we move to the right.
Therefore, the correct interpretation is the value 7 digits to the <em>right</em> of -4.
D is the correct answer.
Hey there! :D
Think of this like a triangle. The dock is 15 feet above ground. It is the side of the triangle. The line connecting the bottom of the dock to the base of the conveyor belt is 40 feet. This is like the base.
The conveyor belt itself is at a diagonal, and should be the hypotenuse.
Use the Pythagorean theorem.
a^2+b^2=c^2
15^2+40^2= c^2
225+1,600= c^2
Add the values together.
1,825= c^2
Find the square root of 1,825.
c= 42.7 (rounded to the nearest tenth)
The conveyor belt is 42.7 feet long.
I hope this helps!
