RPM   =  Pages read / number of minutes  ....so we have

[ 8 + 1/3]  / 5   =

[25/3] / [5 / 1]   =

25/3  *  1/5   =

25/5 * 1/3  =

5 * 1/3   =

5/3   = 1 + 2/3  pages per minute

i got 12.56

V  = [ pi/3 ] * r^2 * h  =    [pi/3] * 1.2^2 * 5   = about 7.54 units^3

It is really nice that you said thank you. All answerers really appreciate people like you.

Just next time could you please put your thank you on the relevant question thread. :)

-3(n+5)=12 n must be -9 because -9+5=-4 then -4*-3=12

-3(n+5)=12

First, use the distributive property.

-3*n=-3n

-3*5=-15

So your new equation is...

-3n-15=12

Next, add 15 to each side to put n on one side.

-15+15=0

12+15=27

You now have...

-3n=27

Finally, divide each side by -3 to make -3n into n.

-3n/-3=n

27/-3=-9

In conclusion...

n=-9

Slope doesn't have anything to do with this unless your slope is the answer.

15-(-10)=x

Whenever you subtract a negative, you can just simply add it. You can change this to...

15+10

15+10=25

So...

15-(-10)=25

I have no idea what you are looking for, but just so you know, this statement is false.

4 - 5 = -1

9 - 5 = 4

-1 does not equal 4.

Ashley rides for 50 minutes, and travels 8 miles.

Since you want to find miles per minute, let's divide both by 50 minutes.

50/50=1 minute

8/50=0.16 miles

So...

Ashley travels at a rate of 0.16 miles per minute.

Note:

Guest, I've noticed that you are posting a lot of problems like these. Did you actually attempt the homework you have, or are you just posting every problem you get? This forum is to help you with math, not to do it for you.

Let's set the whole number, 19, aside.

As for .625, we can just convert that to 625/1000 because the smallest value is the thousandths place.

All we have to do know if reduce!

625/1000 reduces to 5/8.

Now we add 5/8 to 19, and get 19 5/8.

No problem, Guest!

PLEASE DON'T POST YOUR QUESTION TWICE!!. SEE YOUR ANSWER BELOW.

This problem comes from one of the greatest American puzzleists of all time.....Sam Lloyd.....it seems more difficult than it really is......

Let W = the river's width

When they first meet, they have traveled the same amout of time.....one boat has traveled 720 yards and the other has traveled W-720 yards......let the rate of the first boat = R1  and the rate of the second boat = R2  ....and we have that.....

T1     =   T2    ....or......

[720]/R1  = [W - 720]/R2   →   R2/ R1   = [W- 720] / [720]    (1)

Wnen they next meet, they have again traveled the same amount of time......The first boat has traveled the width of the river, (W), plus 400 yards and the second boat has traveled 2W - 400....again  we have that

T3   = T4   ....or.....

[W +  400] /R1  = [ 2W - 400] / R2  →  R2/R1  = [2W - 400] / [W + 400]  (2)

Equating (1) with (2), we have

 [ W - 720] / 720=  [2W - 400] [W + 400]

720[2W - 400]  = [W - 720] [W + 400]

1440W - 288000 = W^2 - 320W - 288000

W^2 - 1760W  = 0

W(W - 1760)  = 0

Reject W = 0......and the solution  is.....W = 1760 yards.....exactly 1 mile wide  !!!!

You want to know how many people came every day on average, so just divide both 14 days and 2,755 people by 14.

14 days/14=1 day

2,755/14=approximately 196.79 people a day

So on average, 196.79 (or 197 rounded too the nearest whole) people a day come to the store.

19.625= 19 and 5/8

carlos reads 8 and 1/3 pages in 5 minutes what is his average reading rate in pages per minute

(81/3) / 5=1 2/3 pages per minute.

8 1/3 pages over 5 minutes is equal to x pages in 1 minute.

All that needs to be done is divide 5 minutes by 5 to equal 1 minute, and divide 8 1/3 by 5, too. 8 1/3 divided by 5 is 1 1/3.

Carlos reads an average of 1 1/3 pages per minute.

Envelope!

It starts with an e and ends with one, but usually only contains one letter in it.

Proportional to what? To each other? No. They have a common factor together such as 3 .

Just divide 8/50=.16 miles per minute.

First get a common denominator 2/3 becomes 16/24 then 6/8 becomes 18/24 so 

16/24+18/24=34/24 or 1 10/24 or 1 5/12

The power seris (in one variable) is an infinite series of the form. where an represents the coefficient of the nth term, c is a constant, and x varies around c (for this reason one sometimes speaks of the series as being centered at c).

A seris  \(f(x) = \sum_{n=0}^\infty a_n \left( x-c \right)^n = a_0 + a_1 (x-c)^1\) Note that i only put the first variable here, but like i said it tends to infinity THE ANSWEAR IS not  \( a_0 + a_1 (x-c)^1\)

What is the value of sin 4/pi and how can we calculate or or convert it ??

4/pi=1.27...........etc. is NOT valid, because sine must be between +1 and -1.

well to get that you do 2755/14 = 196.7857142857142857

 well since you can't have a .7857142857142857 of a person you round up to 197 so about 197 people visited the store each day

Just divide number of people by the number of days.
