mr_godi [17]3 years ago

Here's how I like to represent this:

Randy = 7

Randy * 2 = Ann

Ann + 3 = Janet

Janet + 5 = Donald


If we go along and fill in the blanks for each equation, we do this:

7 * 2 = 14

14 + 3 = 17

17 + 5 = 22

So Donald solved 22 problems.


Hope this helps!

PLEASE HELP WITH EXPLANATION <br><br> F(x) = 3 - x; g(x) = -2x <br><br> find f(g(2))
ioda

Given,

f(x) = 3 - x

and

g(x) = -2x

Now,

g(2) =  - 2(2) =  - 4

f(g(2)) = 3 - ( - 4) = 3 + 4 = 7

You make a time capsule with your friends. Find the surface area of the shape pictured. Use 3.14 to approximate pi.
Orlov [11]

Answer: 1,475.8mm^{2}

Step-by-step explanation:

1. If you join the top part and the bottom part of the figure, you obtain a sphere. Then, you must apply the formula for calculate the surface area of a sphere:

SA_s=4r^{2}(3.14)

Where r is the radius (r=\frac{10mm}{2}=5mm)

2. Then:

SA_s=4(5mm)^{2}(3.14)=314mm^{2}

3. The formula for calculate the suface area of the red part, which is a cylinder, is:

SA_c=2(3.14)(r)(h)

Where h is the height (h=32mm)

4. Then:

SA_c=2(3.14)(5mm)(32mm)=1,004.8mm^{2}

5. So, the total surface area is:

SA_t=314mm^{2}+1,004.8mm^{2}=1,318.8mm^{2}

Question help a lottery game has balls numbered 0 through 1313. what is the probability of selecting an even numbered ball or a
Licemer1 [7]
So i'm assuming 33^a is saying any number that is a square of 33 inside of 1,313 so first, to find how many even numbers divide 1,313 by two to get 656.5 so if I am not mistaken 656 numbers in 1,313 will be even. Now find all squares of 33 that don't pass 1,313 which is 33 itself and 1,089 because 33^3 is 35,937 so add 2 to 656 to get 668. so the probability is 658/1,313 i believe.
