The answer is 13 cm

a = height , b= base ,c = hypotenuse

a^2 + b ^2 = c ^2 ( theorem of Pythagoras)

(12cm)^2+ (5cm)^2 = hypotenuse

144cm^2 + 25 cm ^3 = hypotenuse

169cm^2 = hypotenuse

Square toot of 169cm ^2 = hypotenuse

Answer : 13 cm = hypotenuse

30/2.5 = 12

check:

12(1 hour) +12(1 hour) +6(Half hour) = 30

(x/7) +5 =

Quotient means division, so the expression is to divide x and 7 and then add 5

<em>**Answer:**</em>

<u><em>**15,828.7**</em></u>

<em>**Step-by-step explanation:**</em>

**1)** Use 3.14*r^2 the radius is half of the diameter.

**2)** 142/2 = 71

**3)** 3.14*71^2 = a

4) The area of the pumpkin pie is 15,828.74

5) Round to the nearest tenth <u><em>**15,828.7**</em></u>
