Answer:

352 m

Step-by-step explanation:

The area of a trapeze is (the biggest base + the smallest base) × height / 2

The area from rectangles are side a × side b

Trapeze: (6+12)×4/2 = 36

Rectangles: 5 × 10 = 50

6 × 10 = 60

12 × 10 = 120

There are two trapeze andtwo rectangles with the samesize, so you double their area:

2×36 + 2 × 50 + 60 + 120 = 352 m

Answer:

He will cover 2,827.433 feet² area of the park with plant food.

Step-by-step explanation:

The diameter of the garden is 60 feet and the radius will be 60 feet/2 = 30 feet.

diameter= 60 feet

radius = diameter/ 2= 60/2= 30 feet

The area of the circle can be found by the formula πr²

Area= πr²=π(30)²

Area = 900π= 2,827.433 feet²

He will cover 2,827.433 feet² area of the park with plant food.

Use the rules of exponents to simplify the expressions. Place a final answer in fraction form. (-1/2)to the power of 3 *(-1/2) t

Pavlova-9 [17]

Answer:

-1/32

Step-by-step explanation:

we have

$(-\frac{1}{2})^{3} )(-\frac{1}{2})^{2})$

Remember that

The exponent "product rule" tells us that, when multiplying two powers that have the same base, you can add the exponents

$(-\frac{1}{2})^{3} )(-\frac{1}{2})^{2})=(-\frac{1}{2})^{3+2})=(-\frac{1}{2})^{5})=-\frac{1}{32}$
