Answer:

33.72

Step-by-step explanation:

To figure out the answer, we need to find the total area of the rectangle, and then subtract the blank shape.

Lets first find the area of the rectangle. 4x10=40

Lets now find the area of the blank shape. We fill caculate the area of the circle and then divide by 2 because it is a half circle. 4/2=2. 2x2=4. 4x3.14= 12.56/2=6.28

40-6.28= 33.72

Answers

Answer:

15 3/4

Step-by-step explanation:

8+7=15

1/2+1/4= 3/4

15+3/4

Answer:

15 3/4

Step-by-step explanation:

You need to have like denominators before you add so you need to find the LCM (least common multiple) of the two numbers. Then you have to find how much you have to multiply each number by to get the multiple. Then you just have to remember that whatever you do to the bottom you do to the top.

1. 8 1/2 + 7 1/4     This is your equation.

2. 8 2/4 + 7 1/4      The LCM of 2 and 4 is 4. You multiply by two in the bottom to get 4 so you multiply by 2 at the top. (This is talking about the first fraction).

3. 15 3/4    Then you just add as you would normally add without changing the denominators an simplifying if you need to. (You don't need to simplify for this equation).

I hope this helped you.
