Answer:

Width = 5

Length = 2*5 = 10

Step-by-step explanation:

Givens

Let the width = W = x

Let the length = L = 2x

Equation

Area = L * W

Solution

Area = 2W * W Substitute into the given equation

Area = 2W^2 Simplify the right

50 = 2W^2 Divide by 2

50/2 = 2W^2 / 2 Simplify

25 = W^2 Switch

W^2 = 25 Take the square root of both sides

sqrt(w^2) = sqrt(25)

Answers

w = 5 ft

L = 2 * 5 = 10 ft

The distance a car travels is directly related to the time it travels. The distance is 300 miles when time is 5 hours. What is t

Y_Kistochka [10]

Because the distance a car travels is directly related to the time it travels, the distance varies directly with the time: d=a*t. "a" would be the constant of variation. Just substituted the given values(300 and 5) into the equation, and you would get 300=5a. Divide both sides by 5 and you get a=60. So, the constant of variation is 60

Pile Y has the greater mean number of pages per book because it is 5 books less than pile W.

<h3>How to calculate greater mean number of pages?</h3>

From the complete information, we can deduce that the number of each pile of book is given as follows:

Red books = 10 × 5 = 50 red books.

Blue books = 5 × 5 = 25 blue books.

Therefore, total books in pile W = 50 + 25 = 75 books.

Mathematically, the mean for each pile can be calculated by using the following formula:

Mean = [F(x)]/n

Mean = 75/10

Mean = 7.5.

Red books = 10 × 5 = 50 red books.

Mean = [F(x)]/n

Mean = 50/5

Mean = 10.

In conclusion, pile Y has the greater mean number of pages per book because it is 5 books less than pile W.

examine the graph below. select the solutions to the graph from the following points. select three that apply.

vova2212 [387]

Answer:

Options (1), (2), (3)

Step-by-step explanation:

Let the equation of the line is,

y = mx + b

Here m = slope of the line

b = y-intercept

Given line on the graph is passing through two points (-3, 0) and (0, 1).

Slope of this line will be,

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

= $\frac{1-0}{0+3}$

= $\frac{1}{3}$

y-intercept of the line 'b' = 1

Equation of the line will be,

y = $\frac{1}{3}x+1$

If the points given in the options satisfy the equation, they will be the solution of the line.

Option (1),

For (3, 2),

2 = $\frac{3}{3}+1$

2 = 2

True.

(3, 2) is the solution.

Option (2)

For (21, 8),

8 = $\frac{21}{3}+1$

8 = 8

True.

(21, 8) is the solution.

Option(3)

For (-15, -4),

-4 = $\frac{-15}{3}+1$

-4 = -4

True.

(-15, -4) is the solution.

Option (4)

For (12, 9)

9 = $\frac{12}{3}+1$

9 = 5

False

(12, 9) is not the solution.

Option (5)

For (-6, 1)

1 = $\frac{-6}{3}+1$

1 = -1

False

(-6, 1) is not the solution.

Therefore, Options (1), (2), (3) are the solutions.
