Mathematics
1 answer:
Taya2010 [7]4 years ago
5 0

Answer:

-(-4.1b - 6c - 8) = 4.1b + 6c + 8

Step-by-step explanation:

Given

-(-4.1b - 6c - 8)

Required

Simplify

To solve this using distributive property, we simply open the bracket

-(-4.1b - 6c - 8)

This becomes

= -1 * -4.1b -1 * - 6c -1 * - 8

= 4.1b + 6c + 8

Hence;

-(-4.1b - 6c - 8) = 4.1b + 6c + 8

The formula for the bowline of a sphere is V=4/3πr^3. solve for r
Tpy6a [65]

Answer:

r=\sqrt[3]{\frac{3V}{4\pi}}

Step-by-step explanation:

v= \frac{4}{3} \pi r^3

We need to isolate 'r'

To isolate 'r' , first multiply by 3 on both sides

3v=4* \pi r^3

divide by 4pi on both sides

\frac{3V}{4\pi} = r^3

Take cube root on both sides

\sqrt[3]{\frac{3V}{4\pi}}= r

Initially, the ratio of Ed’s toy cars to Pete’s toy cars was 5:2. After Ed gave 30 toy cars to Pete, they each had an equal numb
Burka [1]
So here is the answer. Initially, Ed's toy cars compared to Pete's toy cars was 5:2. So for every 5 cars that Ed has, Pete has 2. Now that Ed gave 30 cars to Pete. So here it goes. The total number of ratio units is 5+2=7, so each will have an equal number if they both have 3.5 ratio units. That is, if Ed transfers to Pete 1.5 ratio units, their car counts will be equal. Thus 1.5 ratio units = 30 cars, or 1 ratio unit = 20 cars. Therefore, this makes <span> 7*20 cars = 140 cars.

What is the equation in slope-intercept form of a line that passes through the points (5,3) (4,-3)
Darya [45]

Answer:

y=6x-27

Step-by-step explanation:

To find the slope of a line given 2 points; use this equation.

\frac{y_2-y_1}{x_2-x_1} = \frac{rise}{run}

(5,3) (4,-3)

x_1   y_1    \\x_2  y_2\\\\

\frac{3 - (-3)}{4-5} =\frac{-6}{-1}  = 6

slope = 6

as for y-intercept use this method in the attachment
