Answer:

$\frac{y_2-y_2}{x_2-x_1}=m=\frac{-5-3}{1_(_1)} \\ m=-\frac{8} {2}=-4\\ \frac{y-y_1}{x-x_1}=m\\ \fracp{y-3}{x+1}=-4\\y-3=-4(x+1)\\ y-3=-4x-4\\y=-4x-1$

klio [65]

Answer:

see below

Step-by-step explanation:

First we need to find the radius

r =d/2 = 15.8/2 = 7.9 cm

The area of a circle is given by

A = pi r^2

= pi ( 7.9) ^2

=62.41 pi

Using 3.14 for pi

195.9674

To the nearest hundredth

195.97

Using the pi button

196.0667975

To the nearest hundredth

You earn $28 for washing 7 cars. How much do you earn for washing 6 cars?

iren [92.7K]

━━━━━━━━━━━━━━━ ♡ ━━━━━━━━━━━━━━━

Since you can earn 28 dollars by washing 7 cars, and you want to find the amount money you can make by washing 6 cars.

$\frac{28}{7} = \frac{x}{6}$

First, you should find the amount of money you can make by washing 1 car (unit rate).

$\frac{28}{7} = \frac{x}{1}$

To get from 7 to 1, you have to divide 7 by 7; 7 ÷ 7 = 1.

Do the same thing to the numerator; 28 ÷ 7 = 4.

Now you know how much you make by washing 1 car, you need to find how much you make by washing 6 cars.

$\frac{4}{1} = \frac{x}{6}$

To get from 1 to 6, you multiply by 6. 1 times 6 equals 6.

Now do the same thing to the numerator; 4 × 6 = 24.

You can earn 24 dollars by washing 6 cars.

Could someone please help me

The formula for a cone is
$v = \pi \times {r}^{2} \times ( \frac{h}{3} )$
insert 20 for your height and rearrange the formula to find the radius. Leave a comment if you need more help.
