9 divided by 4 = 9/4.

Well....without knowing the question, I couldn't  determine which might be correct...

Oh and the awnser to mine is either 4% 12% 25% or 0.04% so wait my awnser would be 12%??

Divide :

( Number who like bowling )   /  ( Total number in survey)

This will produce a decimal......move the decimal two places to the right and add a " % " sign

8+27+12+9+11+18+18+8+30+29+8+812+10+10+18+28 = 1056

1056/16 = 66

Thank you CPhill, you're always so helpful! :) 

Radical form

V  = pi *r^2 * h         divide by  pi * h

 V / (pi * h)   =   r^2     take the square root of both sides

√  [  V / (pi * h) ]    = r

Exponential form

[ V / (pi * h) ] ^ (1/2)  = r 

4356 pi   =  pi * r^2 * 9       divide both sides by 9pi

(4356 pi ) / ( 9 pi)  = r^2

484   =  r^2       take the square root of both sides

22 cm  = r

Did you try to see if Wolfram/Alpha will give you an answer?

measure of arc across from 39º + measure of arc across from xº = 180º

(2 * 39) + (2 * x) = 180

39 + x = 90

x = 90 - 39 = 51º

You got it! 👍

Triangle A'B'C'   will  be (scale factor)^2  times as large as ABC.....iin other words, 4^2  = 16 times the area......

11.28/3.28 = 3.5 pounds of cheese

70/36.5 =1.06^n

 1.9178= 1.06^n

n = Log(1.9178) / Log(1.06)

n = 11.175 Years. Or in about 2011.

I can try, but I might get it wrong!

Is this the function: P(n) = 36.5 (1.06)ⁿ

We want to solve for n when P(n) = 70

70 = 36.5 (1.06)ⁿ

70/36.5 = 1.06ⁿ

ln(70/36.5) = ln(1.06ⁿ)

ln(70/36.5) = n * ln(1.06)

\(\frac{\ln(70/36.5)}{\ln(1.06)}=n\approx11.176\)

So..since the function considers the year 2000 the starting point,

The population should reach 70 thousand in the year 2011  

 yeah

How many "three-fourths" feet of wire are in \( 10\frac12 \) feet of wire?

\(10\frac12 \div \frac34 \\~\\ \frac{21}{2} \div \frac34 =14\)

There are 14 "three fourths" feet of wire in \( 10\frac12 \) feet of wire.

So, there are 14 pairs of earrings that navya is able to make.

14 pairs

cool!! Thank you.

I reread the question it does say what I wrote. But the answer is wrong when I put that amount in.  It seems like I made you mad. Sorry if I did.
