Hint 1: divide the region into two semi-circles and a rectangle.

Edit: sniped

We can change this shape into two easier shapes to deal with: 2 semi circles and 1 rectangle.

Now, we see that 2 semi circles is equal to one circle. So, let's first calculate the area of the circle. That is pi(r^2), which in this case is 16pi. (I got the radius from half of 8)

Now, what about the rectangle? We know that the width is 8...but what about the length? Well, it's not 18! As you see, we need to subtract 2r, which is 8, from 18. This gives us 10. So, 8(10) is 80.

Now, adding the two areas together, we get 80+16pi.

As follows:

Let TU and VW be chords of a circle, which intersect at S, as shown. If ST = 3, TU = 15, and VW = 3, then find SW.

Volume of a pyramid = 1/3  A_b h

Let x  be  the weight  of a sack of sugar

Let y  be  the weight  of  a sack of flour

We  have  these inequalities

2x + 3y ≤  40

y - 2x ≤ 6

See  the  graph here  :  https://www.desmos.com/calculator/rlbzlpxzgz

The    max  weight  of a sack of flour  occurs  at the "corner point" of  the  feasible region  =   11.25  lbs

You want to use the intersecting chord theorem. This means that:

60^2 = (48)(48+x)

It should be very simple from here! 

2^2 = 4  

3.5^2 = 12.25

 4< integer < 12.25      you can count them

2 5/8 or  2.625

P = 2( 5+4+3+2 ) 

No matter how many friends bring money, or how many people eat.....   Bertha brought 3 out of (4 +3 ) = 3/7 of the food....she should get 3/7 of the money

IMO  

4 / 24 =1/6 of a yard/sec. Its speed downstream

4 / 40 =1/10 of a yard/sec. Its speed upstream

[1/6 + 1/10] / 2 =2/15 yards/sec. Its speed in stillwater.

Thanks much. That makes a lot of sense. You guys really know how to make a neat answer!

40%  of total is yellow and yellow  is  equal to   green fish - 6            (yellow = green -6)

.4  (green + yellow) =  green - 6

.4 (green + green - 6) = green - 6

.8 green - 2.4 = green - 6

3.6 = .2 green

green = 18                                   yellow = 12  

The average of two 2-digit positive integers is equal to the decimal number obtained by writing one of the two-digit integers before the decimal point and the other two-digit integer after the decimal point. What is the smaller of the two integers?

x:    from R to S is   21 units         2/3  x  21   added to -6 =  8

y:    from  R to S is  -24 units        2/3  x -24  added to 19 = 3

Ilorty is correct....    the    -49  thru -1   cancel out the   +1 thru + 49   and you are left with  50 + 51 = 101    sum of 101 integers (including zero)

Pretty straightforward..... see if you think so:

The two semicircle ends form a complete circle of diameter 30  :      distance =  pi * d

then add the two 50 m sides       Done !

Five years ago   Joseph was    33- 5 =   28 y/o        He WAS twice as old as Ann who must have BEEN 14

                                                                                                                 ..... and add 5 more to find here age in 5 years time ......

I am a bit confused at what you mean n=-40.0891...

How is -4949/101=-40.0891? 

Maybe check your math...

P.S. Next time, maybe be a little nicer instead of saying "This screws up your answer"

OK sorry!
