Given

Caisha has a circular garden with a radius of 4 ft.

She needs to put a layer of soil on top. e

Each bag of soil covers 9.42 square feet.

<h3>What is the radius of a circular garden?</h3>

The radius of the circular garden is equal to the pie times of the square of the radius.

The radius of the circular garden is;

\rm Area = \pi r^2\\\\Area = 3.14 \times (4)^2\\\\ Area = 3.14\times 16\\\\Area =50.24

Therefore,

The number of bags of soil will she need to buy is;

\rm = \dfrac{Area }{Soil \ covers}\\\\= \dfrac{50.24}{9.42}\\\\= 5.33\\\\= 6 \ bags \ apporx

Hence, she needs to buy 6 bags of soil.

The manufacturer's price for a cooler is $28.50 A camping store that buys the coolers sells them for $40.76 What is the approxim
Nutka1998 [239]

The percent of the increase is

I=\frac{N-O}{O}\times100

I is the increasing value

N is the new value

O is the original value

The price of the cooler is $28.50, then

O = 28.50

The selling price of the cooler is $40.76, then

N = 40.76

We will substitute them in the rule above to find I

I=\frac{40.76-28.50}{28.50}\times100

Let us calculate it

I = 43.0175 %

Round it to the nearest percent

I = 43%

The answer is D

The ordered pairs (1, 3), (2, 9), (3, 27), and (4, 81) represent a function. Write a rule that represents this function.
Art [367]
Let x be the first number each pair and y is the second of each As you see 1x is 3y
And. 2x is 3*3y= 9y
3x = 3*3*3y= 27y

Last 4x =3*3*3*3y= 81y

So y = 3^x
