Well, if the radius is 10, then the circumference is \frac{2*10*22}7=\frac{440}7
What's the unit? Either way, 22 rev. per minute means each minute you go by 22*\frac{440}7=\frac{9680}7 units per second. Now you got the linear speed, just find out the time by dividing the distance by the speed!
So, what's the unit for the radius?

Help me plssss<br> Find m &lt; ABC.
jonny [76]

Answer:

m<ABC=51°

Step-by-step explanation:

The inscribed angle is half the measure of the intercepted arc. This means that angle ABC=1/2 arc AC

Using this, let's make an equation

5x+11=(1/2)(16x-26)

5x+11=8x-13

11=3x-13

24=3x

x=8

Now go back to angle ABC and substitute for x

5(8)+11=51

m<ABC=51°

How to solve 4x+7=15
Over [174]
<span>4x+7=15

First step is to subtract 7 from both sides to get rid of it.
4x + 7 - 7 = 15 - 7
4x = 8

Now all you have to do is divide both sides by 4.
4x/4 = 8/4
x = 2

The answer is x = 2.</span>

Leena walked 2/3 of a mile What is 2/3 written as a sum of unit fractions with the denominator of nine
aliya0001 [1]
Bear in mind that multiplying anything, and anything whatsoever by 1, has a product of the anything itself.

so, let's multiply 2/3 by 1 then and check about,

\bf \cfrac{same}{same}=1\qquad thus\cfrac{2}{3}\cdot 1\implies \cfrac{2}{3}\cdot \cfrac{3}{3}\implies \cfrac{6}{9}&#10;\\\\\\&#10;\textit{now, we can split that and write it as a sum}\implies \cfrac{1+5}{9}\implies \cfrac{1}{9}+\cfrac{5}{9}

Pls answer 18 20 and 22 show your work
Svetlanka [38]

Answer:

18- 300

20- 1,500

22- 300

Step-by-step explanation:

You can easily find the answer like this:

18. Multiply 60 and 100 together. The hundred is from 100%. After that, divide it by 20 because of the percent. After doing this, you should get 300.

20. 360*100=36,000 36,000/24= 1,500

22. 9*100=900 900/3=300


I hope this is what you were looking for. If you need more out of this, ask me to answer it again. :)
