Write the expression as a monomial in its standard form.<br><br> 9/16p^7 ⋅ (-4/3p^4)
Aleksandr-060686 [28]

Answer:

-3/4 p^11

Step-by-step explanation:

9/16p^7 ⋅ (-4/3p^4)

Multiply the numbers together

9/16 * -4/3 = -3/4

Now multiply the variables

p^7 * p^4

We know that a^b* a^c = a^(b+c)

p^(7+4) = p^11

Putting these back together

-3/4 p^11

Murljashka [212]

Answer:

17.106 Teaspoons of fertilizer

Step-by-step explanation:

Joni has a circular garden with a diameter of 16.5. If she uses 2 teaspoons of fertilizer for every 25 square feet of garden how many teaspoons of fertilizer will Joni need for her entire garden?

Step 1

We calculate the area of the garden.

The garden is circular in shape.

Area of a circle = πr²

r = radius = Diameter/2

Diameter = 16.5 ft

r = 16.5/2

r = 8.25 ft

Area of the circle = π × 8.25²

Area of the circle (Garden) = 213.82464998 ft²

Approximately = 212.825ft²

Step 2

If she uses 2 teaspoons of fertilizer for every 25 square feet of garden how many teaspoons of fertilizer will Joni need for her entire garden?

25 ft² = 2 teaspoons of fertilizer

212.825ft² = x

Cross Multiply

25 ft² × x = 212.825ft² × 2

x = 213.825× 2/25 ft²

x = 17.106 Teaspoons of fertilizer
