V = PI x r^2 x H

471 = 3.14 x 5 x H
471 = 15.7 x h

h = 471 / 15.7 = 30 cm

314/ 15.7 = 20 cm

30-20 = 10 cm difference

What is the equation of the line passing through the points (4, -7.5) and (6, -3.5) in slope-intercept form?

Ratling [72]

Answer:

Your answer will be

y=2x-15.5

Step-by-step explanation:

Hi, there you must know the slope-intercept form which is

y=mx+b

m=slope

b=y-intercept

You can also use

the slope formula which is

$\frac{y_2-y_1}{x_2-x_1}$

in this case

it will look like this

$\frac{-7.5-(-3.5)}{6-4}$ = $\frac{-4}{2}$ =-2

So the slope is -2

Now we will find the y-intercept

-7.5=2(4)+b

-7.5=8+b Subtract 8 both sides

-15.5=b

Your y-intercept is -15.5

Hope this helps

The ratio of points scored by 3 boys in a game is 7:10:12. If the sum of their scores is 232, what was the highest score?

4vir4ik [10]

Answer:

96 points

Step-by-step explanation:

Ratio problems can be solved like this:

Let x equal an unknown value.

Now, we can write an equation.

7x + 10x +12x = 232

We want to find 12x, so we have to find x first. We can simplify our equation to:

29x = 232

Now, divide both sides by 29.

x=8

We then solve for 12x by multiplying 8 and 12, and get 96 points.
