The length of a rectangle is four times its width.
If the perimeter of the rectangle is 70 ft, find its length and width.

Answers

Answer 1
Let L represent length of rectangle

Let W represent width of rectangle

L=4W

2L+2W=70

Substitute 4W for L

2(4W)+2W=70

8W+2W=70

10W=70

Divide both sides by 10

W=7

Use equation from beginning

L=4(7)

L=28

Width is 7 ft, length is 28 ft

Check work

2(28)+2(7)=70

56+14=70

70=70

Answer:

D. y = 2x

Step-by-step explanation:

The slope of the line is 2, so you get 2x. Therefore, the equation is y = 2x.

the equation is answer D

Step-by-step explanation:

the slope is 2 and the y-intercept (b) is zero so it isn't written.

The highest common factor (HCF) of two numbers is 6.
The lowest common multiple (LCM) of the same numbers is 60

What are the two numbers?
Please explain every step

Answers

Answer:

12 and 30

Step-by-step explanation:

HCF = 6 = 2×3 means they both have in common a factor of 2 and a factor of 3, but at least one of the numbers has no more than one of each of these factors.

LCM= 60=2²×3×5 means That the combined product of their factors counting only once the ones they have in common is 60.

so they could be 2×2×3 = 12 and 2×3×5 = 30

The local community center hosted a marathon as a fundraiser. Runner A completed the marathon with a time of 4.37 hours. Runner B completed the marathon in 4.29 hours. Which runner completed the race faster (by having a lower time)? Explain how you know. (100 points + brainliest)

Answers

Based on the information given in the question, the completion time of runner B is lower than that of Runner A ; Hence, runner B completed the race faster.

Given the running time of two runners :

Runner A = 4.37

Runner B = 4.29

The runner with the lesser running time will complete the marathon faster as this means he has a higher speed.

Comparing the running times of both runners :

4.37 > 4.29

Therefore, Runner B completed the race faster than runner A.

Write an equation in Slope-Intercept Form using the table below. ​

Answers

Answer:

y = x + 46

Step-by-step explanation:

When writing an equation of a line, keep in mind that you always need the following information in order to determine the linear equation in slope-intercept form, y = mx + b:

1. 2 sets of ordered pairs (x, y)

2. Slope (m)

3. Y-intercept (b)

First, choose two pairs of coordinates to use for solving the slope of the line:

Let (x1, y1) = (0, 46)

(x2, y2) =  (1, 47)

User the following formula for slope

[tex]m = \frac{y2 - y1}{x2 - x1}[/tex]

Plug in the values of the coordinates into the formula:[tex]m = \frac{y2 - y1}{x2 - x1} = \frac{47 - 46}{1 - 0} = \frac{1}{1} = 1[/tex]

Therefore, the slope (m) = 1.

Next, we need the y-intercept, (b). The y-intercept is the y-coordinate of the point where the graph of the linear equation crosses the y-axis. The y-intercept is also the value of y when x = 0. The y-coordinate of the point (0, 46) is the y-intercept. Therefore, b = 46.

Given the slope, m = 1, and y-intercept, b = 46, the linear equation in slope-intercept form is:

y = x + 46

Step-by-step explanation:

Since all triangles' angles add up to 180 degrees, you can add the sum of the angles you already know and subtract it from 180.

126+24=150

180-150=30

so angle Q = 30 degrees

the answer to your question, the Q equals 30 degrees.

it takes a snail 10 seconds to move 1 centimeter. How far does snail travel in 2 seconds

Answers

Answer:

0.2

Step-by-step explanation:

If it takes 10 seconds to move 1 centimetres, and you want to know about 2 seconds, you can divide by 5 on both sides.

1/5 = 0.20

It takes 2 seconds to move 0.2 centimetres (aka 20 milimetres).

The snail will travel 0.2 centimetre in 2 seconds.

it takes the snail 10 seconds to move 1 centimetre. The means in every 10 seconds the snail moves 1 centimetre.

The distance the snail can cover in 2 seconds can be computed below:

10 seconds = 1 cm

2 seconds = ? cm

cross multiply

distance it takes the snail to travel in 2 seconds = 2 / 10

distance it takes the snail to travel in 2 seconds = 1 / 5

distance it takes the snail to travel in 2 seconds = 0.2 cm

Therefore, the snail will travel  0.2 cm in 2 seconds .

Define your variables as
"C" = # of children
"a" = # of adults
Write a system of equations to represent this information solve the system to find out how many children and how many adults came to the amusement park that day.

Answers

Answer:

Children = 124

Adults = 93

Step-by-step explanation:

x = children

y = adults

x + y = 217

x = 217 - y

15.50x + 20y = 3782

15.50 (217-y) + 20y = 3782

3363.50 - 15.50y + 20y = 3782

4.5y = 3782 - 3363:50

y = 418.50/4.5

y = 93

x + 93 = 217

x = 217 - 93

x = 124
