The volume of a sphere is 267.95 m2. To the nearest meter, what is the radius of the sphere? Use
Novosadov [1.4K]

Answer:

4m

Step-by-step explanation:

  1. v=4/3 pi r^3
  2. substitute 267.95=4/3×3.14×r^3
  3. 267.95= 12.56r^3/3
  4. multiply by the reciprocal on both sides 64=r^3
  5. find the cuberoot on both sides to remove the cube hence 4=r

Click here What is the average rate of change for this exponential function for the interval from x=2 to x = 4? 15 10 -5 5 10 O
Triss [41]

Answer:

c. 6

Step-by-step explanation:

Given

See attachment for graph

Required

Average rate of change

This is calculated as:

Rate = \frac{f(b) - f(a)}{b - a}

Where

(a,b) = (2,4)

So, we have:

Rate = \frac{f(4) - f(2)}{4 - 2}

Rate = \frac{f(4) - f(2)}{2}

Using the attached graph, we have:

f(2) = 4

f(4) = 16

So, we have:

Rate = \frac{16- 4}{2}

Rate = \frac{12}{2}

Rate = 6

An office manager spent $4870 on a
Andrews [41]

Answer:

6 chairs

8 desks

Step-by-step explanation:

First, we assume that all 14 items he bought were chairs, if that was to be true then the office manager would spend...

125 x 14 =  1750$

We see that he spent less then he should have so now we start to substitute desks instead of chairs, and we have to keep in mind that if we change 1 chair to a desk then the total will increase by...

515 - 125 = 390$

Now we just find the difference between the needed total and the total that we get if the office manager would by only chairs and then divide the result by 390 in order to find the number of desks, and so we get...

(4870 - 1750) / 390 = 3120 / 390 = 8 desks

And now that we know the number of desks we just subtract the number of desks from 14 and get the number of chairs, and so...

14 - 8 = 6 chairs
