Thx! :)

Good Job! ;)

-(121^.5) = -11

OR

(-121)^.5 = Error: not real

;))))))))))))))) 

X=4240:(164Y+24Yx2) 

But basically you count with 164 portions for cats, and since the dog supplies are twice as much, you double the bumber of dogs, so it's 48. 

Now add up 164+48, which is 212. So in total, you are basically buying 212 portions of supplies, since you need 2 portions for the dogs. 

Now divide 4240 by 212 and you get 20. 20 is the cost per portion, so for a dog it would be $40.

I hope I did it okay.

Hiyaa

Solveit  is correct......

Just take the amount of the total job that each pipe can do in one hour, 1/20 and 1/30, respectively......add them   and take the reciprocal.......this is the time - in hours - to complete the job

Hey 

1. 40% of 75 is 30

75*.4=30

2. 30 is 33% of 90

90*.333...=30

3. 55 is 20% of 275

55/.2 = 275

4. She will have to sell 114 boxes because 95*.2=19

95+19=114.

1.  what is 40% of 75

 75 x 40 / 100 
 3000 / 100 
 30

3. 100%/x%=90/30
(100/x)*x=(90/30)*x       - we multiply both sides of the equation by x
100=3*x       - we divide both sides of the equation by (3) to get x
100/3=x 
33.3333333333=x 
x=33.3333333333

I'll let Rar do the rest!! <3

the height is x

you have:

L-length

W-width

H-height

V=L*W*H

their volumes are same and you know L W H of the first one and L W of the second one

L1*W1*H1=L2*W2*H2

\(2*3*4=3*2*H\)

H=4

The function is 8x 

Substituting 7 for x, it would equal 56

7*8=56

Hehe. <3

Let's use 3.14 for pi.

3.14*12 = 37.68

So the circumference is 37.68 ft

EDIT: Hayley, you beat me to it. +5

All thanks Guys 

Hey Lak!! :)

Matt conducted a survey to determine his classmates’ favorite professional baseball team. After polling 45 classmates, Matt arranged his data in the table below.

Favorite Baseball Team

Team

Number of Students

Atlanta Braves

9

Chicago Cubs

9

Colorado Rockies

1

L.A. Dodgers

1

New York Mets

10

Philadelphia Phillies

3

Pittsburgh Pirates

6

Boston Red Sox

5

Texas Rangers

1

What fraction of the people that Matt surveyed named the Philadelphia Phillies or the Pittsburgh Pirates as their favorite team? Write the fraction in simplest form.

If d= 12 feet, then C=12*pi  feet, which is approximately 37.68 ft. 

........???

Why is there always a spanish post?

how do u find the height?

Hayley, that would be 7 divided by 2 divided by 3.

Instead do 7 2/3

Or make it an improper: 23/3

Or make it a decimal: 7.6666......
