#9 . . . #12, and #14:  Excellent.  All correct, and good estimates.

#13:  A very picky comment: 
Your math is correct, but the camera can't take 2/3 of an image. 
That's why the question asked "How many complete images ...".
After 66 images, there is still some time remaining, but not enough
for another image.  So it captures 66 complete images in 3 seconds.


If you are really in elementary school, then I think you're doing
the work of a prodigy.  Keep it up !  And best of luck to you.

First, you should solve for f(2x), which equals 2*(2x)=4x.  Now, solve the integral of f(2x)=2*(2x)=4x, to get that\int\ {(f(2x)=4x)} \, dx= 2x^2.  You can check this by taking the integral of what you got.  Now by the Fundamental Theorem\int\limits^2_0 {4x} \, dx=[2x^2] ^{2}_{0}=2(2)^{2}-2(0)^2=8.

This should be the answer to your question, if I understood what you were asking correctly.

In a class of 47 students, the number of males is 7 less than twice the number of females. How many females and how many males a
Rom4ik [11]
X=number of females
47-x=number of males
# of males is 2*(number of females)-7:
47-x= 2x-7
add x to both sides:
47=3x-7
add 7 to both sides:
54=3x
divide both sides by 3:
x= 18 females
47-18= 29 males

A sign language club made $627.50 from selling popcorn at a festival. The popcorn cost the club $95.00. Which expression represe
Charra [1.4K]

Answer:

(627.50-95)/m

Step-by-step explanation:

The total value of money earned was $627.50. Then subtract the amount of money the popcorn cost, $95.00. This subtraction would make the difference of $532. This equation would be in parentheses because you have to get the difference before you can divide the profits among the club members. After you put that into parentheses, divide the difference by M. This will give you the equation (627.50-95.00)/m hope this helps!
