The way tires on wheels work is that when the wheel turns one complete
turn, it moves (forward or backward) by a distance that's the circumference
of the tire.

Now, we know that the circumference of a circle is (π) times the diameter.
The diameter of the tire on this bus is 1 meter.  So its circumference is
(π · 1 meter), and every time it turns once, the bus moves 1 meter down
the road.

If the tire rotated 8,000 times, then the bus moved 8,000π meters,
or 8π kilometers.

THAT's the exact answer.  If you want to know how far that actually is,
then you take some number that's approximately π and multiply it by
8 km.  You can never get an exact answer like that, because you can
never write the exact value of π with digits.

In school, we often use  ' 3.14 ' for π .  If you do that, then the bus
traveled

                   (8 km) x (3.14)  =  25.1 kilometers .

When you do that, you have to remember that it's approximate.
If you want an exact answer, then you have to leave π in the answer.

Abdi's bowling scores for June were 117, 98, 104, 121, 105, 104, 120, and 111. What is the mean of this data?
elena-s [515]
The first thing that you have to do is line it up from least to greatest: 98,104,104,105,111,117,120,121. Then you add all of the numbers and divide the total of all the number of scores she has. 880/8=110. 110 is the answer of your question. ( I got 8 because I had to count all the numbers and I got 880 because I added all the numbers).

Answer: No solution

Step-by-step explanation:

Perimeter= 2(length) + 2(width)

If they have the same perimeter than we can write their values as an equation like this:

2(10) + 2x = 2(6) + 2(x + 3)

20 + 2x = 12 + 2(x+3)

DISTRIBUTE THE 2 TO THE X AND THE 3

20 + 2x = 12 + 2x + 6

COMBINE LIKE TERMS

20 + 2x = 18 + 2x

SUBTRACT 2X FROM BOTH SIDES

20 = 18

<u>THE EQUATION HAS NO SOLUTION, AND YOU ARE CORRECT</u>

Interest calculated on a balance every three months is said to be compounded quarterly.
Mariulka [41]

Answer:

True

Step-by-step explanation:

The year is typically divided into equal different lengths of time. There are, for example, quarters, which divide the year by 4, i. e., in 4 periods of 3 months each. Other example are semesters, in this case, the year is divided into 2 periods of 6 months each. Taking this into account, an interest calculated on a balance every three months is compounded quarterly.
