Answer:

D. 3

Step-by-step explanation:

Assuming the model represents an equation, the following can be deduced:

On the left side of the equation, the model shows we have 3 "x's", and 6 "1's". Let this represent:

3x + 6

On the right side of the equation, we have 2 "x's" and 9 "1's". Let this represent:

2x + 9.

The model would represent the equation below:

3x + 6 = 2x + 9

Solve for x

3x + 6 - 2x = 2x + 9 - 2x (Subtracting 2x from both sides of the equation)

x + 6 = 9

x + 6 - 6 = 9 - 6 (subtracting 6 from both sides of the equation)

x = 3

1, 2, 3, 4, 4, 7

The middle numbers are 3 and 4. The number between 3 and 4 is thus the median - this number is 3.5

What is the answer? ​
Inga [223]

Answer:

1) 189.25 square inches

2) 21 square feet

Step-by-step explanation:

1) In order to find the area of a semicircle, you use  (πr^2)/2. When you plug in 3.14 as pi and 5 as your radius, you'll get 39.25. The area of the rectangle is base x height which is 10 x 15/150. 150 + 39.25 = 189.25

2) If you draw a vertical line that is parallel to the 2 feet measure, you'll have two rectangles with areas (5x3) and (3x2). 15 + 6 = 21
