Calculate the sphere volume vv

Answers

Answer 1

Answer:

The volume of the sphere equals 2,393.9 [tex]cm^{3}[/tex] if we were to round to the nearest tenth.

Step-by-step explanation:

The volume of the sphere can be found by using the following formula...

(In the following formula "r" is the radius)

Volume = (4π[tex]r^{3}[/tex]) / 3 = [tex](4)(3.14)(8.3)^{3} / 3[/tex] ≅ 2,393.9 [tex]cm^{3}[/tex]

Answer 2

Answer:

2393.9

Step-by-step explanation:

4πr³/3=4π(8.3)³/3=4π*571.787/3=4*3.14*571.787/3≈2393.9

Paul is comparing two high-speed Internet service providers (ISPs) for his business. The graph represents the cost of each ISP as a function of t, the duration in months of a service contract.

A coordinate grid showing Internet Service Provider Cost, with Service Contract in months along the horizontal axis, and Total Cost in dollars along the y-axis. Two lines are graphed. One line is labeled I S P A and passes through (0, 180) and (12, 300). The second line is labeled I S P B and passes through (0, 0) and (12, 300).

If C(t) = 180 + 10t represents ISP A and C(t) = 25t represents ISP B, how long would the service contracts need to be for the total costs to be the same?

6 months
8 months
10 months
12 months

Answers

Answer:

12 months

Step-by-step explanation:

Theres an awful amount of needless information to get through.

Only the last paragrph is needed.

C(t) = 180 + 10t

C(t) = 25t

Set the equations equal

25t = 180 + 10t

Subtract 10t from both sides

15t = 180

Divide both sides by 15

t = 12

The answer for x is 80°

Step-by-step explanation:

60°+40°+x=180°

X=180°-60°-40°

X=80°

It’s 80 because the sum of all the angles should be 180 so you’d subtract the angles u already have which is 60+40=100 and then u subtract that from 180 and u get 80

X=80

Answers

Answer:

About 6.32 hours.

Step-by-step explanation:

P= production

t=# of hours needed

How many hours are needed to reach the production level of 400?

Plug the numbers into the formula given.

400=300+50 ( t-10 squared)

Combine like terms- 400=350 (t-10 squared)

subtract 350 from itself, then do the same to the other side.

400-350=350-350(t=-10 squared)

50= (t-10squared)

50-10= 40 squared

40 squared= about 6.32.

Hope this helps! Have a nice day :)

Lydia buys peanut butter in bulk for $0.20 an ounce. How much does 18 ounces of the peanut butter cost?

Answers

Answer:

3.6 dollars

Step-by-step explanation:

Lets go over what we know:

Each ounce of penut butter cost 0.2$, or 1/5$

We need 18 ounces.

To solve this, lets multiply the cost per ounce by the amount of ounces:

0.2*18

1/5*18

18/5

This can be simplfied into:

3 3/5

We know each 1/5 is 20 cents(0.2), so 3 cents would be 3*0.2 = 0.6:

3.6 dollars

So the answer is for 18 ounces, it cost 3.6 dollars.

Hope this helps!

3(x−2)=2(x−3)

(3)(x)+(3)(−2)=(2)(x)+(2)(−3)(Distribute)

3x+−6=2x+−6

3x−6=2x−6

Step 2: Subtract 2x from both sides.

3x−6−2x=2x−6−2x

x−6=−6

Answers

Answer:

y = 800,000[1.03]

Step-by-step explanation:

Given:

Number of people attend 2012 country fair = 800,000

Attendance increases = 3% per year

Find:

Function represents attendance after 2012

Computation:

A = P[1+r]ⁿ

Assume;

Number of people attend country fair after 2012 = y

So,

y = 800,000[1+3%]¹

y = 800,000[1+0.03]

y = 800,000[1.03]

Function represents attendance after 2012 is y = 800,000[1.03]
