Ok I have no idea if this is what it’s asking but I’ll give it a try

24inch=2 ft

2r=24 then r=12inch=1ft

V=πr^2.h

π.1.40= 40πft^3 so the answer I think is 40π

I have to find the variable but is it 20/7= 24/x or 24/20= 7/x

harkovskaia [24]

It can actually be done many ways. You must match up the corresponding sides.

For example, 24/20 and x/7 would work so would, 24/x and 20/7, and 7/20 and x/24. Most proportions are set up the same way. You just have to make sure to go in the same order for the two triangles. Sorry if it's confusing.

So let's use-20/7 and 24/x.

First, we multiply 7*24 and 20*x and we get 20x=168

Then we divide to get 168/20. X=8.4

If point P(4, 7) is on line l, what is the equation of line l in slope intercept form?

alexira [117]

Answer:

A. y=2x-9

Step-by-step explanation:

A. Parallel lines have the same slope. That means the line y=2x+3 has the same slope as any line parallel to it. So the slope is 2.

Using m=2, substitute it and (4,-1) into the point slope form and simplify to find the y-intercept.

In a game called Taxation and Evasion, a player rolls a pair of dice. If, on any turn, the sum is 7, 11, or 12, the player gets

AnnZ [28]

Answer:

$Probability = \frac{243}{1024}$

Step-by-step explanation:

Given

$Sum = \{7, 11, 12\}$

$Rolls = 5$

Required

Probability of not getting audited

If a pair of dice is rolled, the following are the observations of the sum

$Outcomes = 36$

$Sum\ of\ 7 = 6$

$Sum\ of\ 11 = 2$

$Sum\ of\ 12 = 1$

So, in a single roll; The probability of getting audited is:

$p= \frac{1 + 2 + 6}{36}$

$p= \frac{9}{36}$

$p= \frac{1}{4}$

The probability of not getting audited in a single roll is:

$q = 1 - p$ --- Complement rule

$q = 1 - \frac{1}{4}$

Take LCM

$q = \frac{4 - 1}{4}$

$q = \frac{3}{4}$

The probability of not getting audited in 5 rolls is:

$Probability = q^5$

$Probability = (\frac{3}{4})^5$

$Probability = \frac{3^5}{4^5}$

$Probability = \frac{243}{1024}$
