Answer: 
Step-by-step explanation:
The area of a rectangle can be calculated with this formula:
Where "l" is the lenght and "w" is the width.
And the area of triangle can be found with this formula:
Where "b" is the base and "h" is the height.
First:
- Convert inches to feet:
- Convert the mixed number to decimal number:
You can identify that the ramp is formed by three rectangles and two equal right triangles.
Since the bottom of the ramp does not have to be stained, you need to find:
1. The area of the smaller rectangle:
2. The area of the larger rectangle on the top:
3. The area of the triangles:
Add the areas:
Since a quart of stain covers 
, for 
you need to buy:
First, I would create a number line that includes the number -4 to 4, with 1/4 notches (3 notches between each number).
For 3, I would count 3 numbers to the right from zero.
For 2.25, I would count 2 numbers from zero, plus one additional notch to the right. Remember that each notch represents 1/4, or 0.25.
For the opposite of 4, I would count 4 to the left to -4. The opposite of 4 is -4.
For -(-1 1/2), I would remember that this number is actually 1 1/2, since a negative times a negative number is positive. I would count one number to the right of zero, plus two notches.
Answer:
.
Step-by-step explanation:
Given:
Kerry and her brother and noticed there is 3/4 of a pint of ice cream in the freezer.
After they eat some ice cream there is 1/3 of a pint left.
Question asked:

Solution:
Total ice cream in the freezer = 
Ice cream left = 
<h3>They ate = Total ice cream in the freezer - Ice cream left after they ate</h3>
Thus, Kerry and her brother ate .
The answer is the first one
C because adjacent angles share a common line as do angles 2 and 4.
Hope this helps :)
