Caisha has a circular garden with a radius of 4 ft. She needs to put a layer of soil on top. Each bag of soil covers 9.42 square feet. How many bags of soil will she need to buy? 5 bag 6 bags 7 bags 8 bags

Answers

Answer 1

Answer:

Answer:

6 bags

Step-by-step explanation:

Hey there!

Well first we need to find the area of the circle using,

π r^2

4*4 = 16

16 * pi ≅ 50.27

So now to find how much bags needed we do,

50.27 ÷ 9.42 = 5.34

Meaning 6 bags of soil is needed.

Hope this helps :)

Answer 2

Answer:

Answer:

Caisha will need 6 bags of soil.

(B.) 6 bags :)

The scatter plot shows a hiker's elevation above sea level during a hike from the base to the top of a mountain. The equation of a trend line for the hiker's elevation is y equals=9.069.06xplus+651651, where x represents the number of minutes and y represents the hiker's elevation in feet. Use the equation of the trend line to estimate the hiker's elevation after 175 minutes.

Answers

Answer:

2236.5

Step-by-step explanation:

The regression equation for predicting hiker's elevation is

y=9.06x+651.

Here x is the number of minutes.

We wish to estimate hiker's elevation after 175 minutes. For this purpose we put x=175 in the predicted regression equation.

y=9.06(175)+651

y=1585.5+651

y=2236.5

Thus, the hiker's elevation after 175 minutes is 2236.5 feet.

log3(2x-5)=2

Answer is 41/2. Why?

Answers

I guess that your question is:

$log[6*(2x-5)]=2$

So, we can apply this property of log

$log_b~(a)=c\Leftrightarrow a=b^c$

them...

$log[6*(2x-5)]=2$

$6*(2x-5)=10^2$

$12x-30=100$

$12x=100+30$

$12x=130$

$x=(130)/(12)$

simplifying

$\boxed{\boxed{x=(65)/(6)}}$

Answer:

0.954243x−2.385606=2

Let's solve your equation step-by-step.

0.954243x−2.385606=2

Step 1: Add 2.385606 to both sides.

0.954243x−2.385606+2.385606=2+2.385606

0.954243x=4.385606

Step 2: Divide both sides by 0.954243.

0.954243x/0.954243 = 4.385606/0.954243

x=4.595901

Answer:

x=4.595901

An apple pie has a 12-inch diameter and the angle of one slice is 60 degrees. What is the area of that slice of pie? Use 3.14 as the value of pi .

Answers

r = 6 in;
60° = 1/6 · 360°
The area of the slice of pie:
A = 1/6 · r² · π
A = 1/6 · 6² · 3.14 = 18.84 in²

An apple pie has a 12-inch diameter and the angle of one slice is 60 degrees. What is the area of that slice of pie?

Answer: This problem is simple. To find the area of that slice of pie we will need to do the following: radius = diameter / 2. Therefore by replacing the values we will get 12 /2 = 6. Finally we use this formula and solve for the answer Area = πr²Θ / 360. The correct answer you should get is 18.84 in².

I hope it helps, Regards.
