Write each rate as a unit rate. 3 inches of rain in 6 hours
y = 3x - 3
and
y = 2x + 2
Answers
6 = 3(3) - 3 --> 6 = 9 - 3 --> 6 = 6 ... So yes, (3, 6) is a solution for y = 3x - 3.
Now let's move on to the next equation. If we plug in the same x and y values, then y = 2x + 2 will change to 6 = 2(3) + 2. Now comes the solving ...
6 = 2(3) + 2 --> 6 = 6 + 2 --> 6 > 8 ... So the coordinates do not work for the second equation since the two answers are not equal.
It isn't.

6).
The volume of a sphere is
(4/3) (pi) (radius)³ .
In #5, the 'pi' is already there next to the answer window.
You just have to come up with the (4/3)(radius³).
Remember that the radius = 1/2 of the diameter.
7). The volume of a cylinder is
(pi) (radius²) (height) .
Divide the juice in the container by the volume of one can,
to get the number of cans he can fill.
8). The volume of a cone is
(1/3) (pi) (radius of the round bottom)² (height) .
He starts with a small cone, he then adds clay to it to make it higher.
The question is: How much clay does he ADD to the short one,
to make the bigger one ?
Use the formula to find the volume of the short one.
Use the formula again to find the volume of the bigger one.
Then SUBTRACT the smaller volume from the bigger volume.
THAT's how much clay he has to ADD.
Notice that the new built-up cone has the same radius
but more height than the first cone.

Don't worry if you don't understand this.
The answer will be this number:
(1/3) (pi) (radius²) (height of the big one minus height of the small one).

You cannot evaluate for (g o f)(0). You will get an undefined answer.
(g o f)(x) tells you to plug in the f(x) function for the x-variable in the g(x) equation; so it would be like saying g(f(x)). This would result in (g o f)(x) = (1/x) - 4. Now plug in 0, (g o f)(0) = 1/0 - 4. One cannot divide by zero in order to simplify the equation and get an answer... unless an undefined answer counts, which I'm pretty sure it doesn't.

Answer:
30 different signals
(n = no. of objects)
(r = no. of objects selected)
Step-by-step explanation:
this is a permutation problem so use the formula:
5P5 / 2! 2! 1! <- its 5 P 5 because there are 5 flags, 2 red, 2 white, and 1 blue
[5! / (5 - 5)!] / 2 x 2 x 1 <- the permutation formula is: n! / (n - r)!
= 120 / 4
= 30
(i know this was like 6 years ago but just in case someone needs the correct answer)
