Answer:

V(s) = 332,9 m³

Step-by-step explanation:

The volume of a sphere is:

V(s) = (4/3)*π*r³

if we know  r  = 4,3 m then

V(s)  = (4/3)*3,14*(4,3)³

V(s)  = 332,8693 m³

Rounding the answer to the nearest tenth

V(s) = 332,9 m³

zhannawk [14.2K]

We have been given some information about the type of car and the number of miles driven.

Using those data with table, we have to find about what will be the repairs and maintenance for this vehicle in dollars and cents.


"Car = 8 cylinder sedan" means use V-8 Sedan which is in the 6th column of the table.


"Year driven = third" Means select Third Year which belongs to 6th column of the table.


"Miles driven = 9,000" means  select catagory in which 9000 miles falls. You can see that number of miles is decreasing in the table when going from left to right direction. So the 6th column (11,5000 miles) is good choice.


we have to find the "repairs and maintenance" which is in 3rd row of the table.

Now  we check where the 3rd row and 6th column meet.

We see that they meet at value 2.3 of the table so we will use that for calculating answer.


Repairs and maintenance cost per mile = 2.3 cents

Number of miles driven = 9000

Then total cost = 9000*2.3 = 20700 cents

To convert that into dollar, divide by 100

20700/100 = 207.00

Hence final answer is 207 dollar and 0 cents.

After 35 minutes, he started charging his phone. 21 minutes later, the battery is at 23%. Explain how you would determine when t
VLD [36.1K]

Answer:

91.30 minutes

Step-by-step explanation:

Assuming that when you start charging the phone it had 0% charge, what you should do is a rule of three.

That is, yes in 21 minutes I charge 23%, how long will it take to charge 100%.

charge time     charge percentage.

21 minutes                  23%

 x minutes                  100%

Then it would be:

x = 100 * 21/23 = 91.30

So you would have to wait 91.30 minutes to wait for the full charge.

A, B, and C are collinear points. B is between A and C. AB = 5x + 8 BC = 6x - 1 AC = 12x - 11 Find AC.
Vlada [557]

Answer:

AC = 198

Step-by-step explanation:

Since all these points are collinear, we know that the addition of AB plus BC should give the same as AC. We can then set an equation that addresses this identity:

AB + BC = AC

5x +8 +6x - 1 = 12x - 11

Now re-arranging like terms in order to combine them:

8 - 1 + 11 = 12x - 5x - 6x

19 - 1  = 12x - 11x

18 = x

Now that we know the value of 'x", we can determine the value of AC:

AC = 12x - 11

AC = 12 (18) - 11

AC = 216 - 18

AC = 198
