How do I set up this problem?

Margaret [11]3 years ago

Hey there!

We know that perimeter is all the sides added up.

70= 2w+2L <== this is the basic equation

We know that the rectangles length is three times as long as it is wide.

So, you know that is is three times the length of the width. So, put 3 times w in as length and times that by two since there are two length sides, and keep width the same. 2w because there are two width sides. Then, solve.

70=2(3w)+2w

70= 6w+2w

70=8w

w=8.75

We can check this by plugging it in to our first equation and seeing if it works. First, we need to multiply 8.75 by 3 to get the value for length.

8.75*3= 26.25

2(26.25)+2(8.75)= 70 <=== it works!

So, the length is 26.25 cm and the width is 8.75 cm.

I hope this helps!

Plot a graph for the following data recorded for an object falling from rest
shusha [124]
  1. The kind of curve obtained is linear.
  2. The relationship between the variables is direct variation.
  3. After 4.5 seconds, I expect the velocity to be equal to 140 ft/s.
  4. The amount of time required for the object to attain a speed of 100 ft/s is 3.2 seconds.

<h3>What is a graph?</h3>

A graph can be defined as a type of chart that's commonly used to graphically represent data on both the horizontal and vertical lines of a Cartesian coordinate, which are the x-axis and y-axis.

In this exercise, you're required to plot a graph for the data (velocity and time) recorded for an object that is falling from rest.

Based on the graph for the data (see attachment), we can logically deduce the following points:

  • The kind of curve obtained is linear.
  • The relationship between the variables is direct variation.
  • After 4.5 seconds, I expect the velocity to be equal to 140 ft/s.
  • The amount of time required for the object to attain a speed of 100 ft/s is 3.2 seconds.

In the past month, Amy rented 7 video games and 4 DVDs. The rental price for each video game was $3.30. The rental price for eac
Lera25 [3.4K]

Answer:

$39.90

Step-by-step explanation:

if each video game cost $3.30, and she rented 7, then you multiply $3.30 by 7, to get $21.10, and if each DVD was $4.20, and she rented 4, then its $4.20x4= $16.80

after that you just add the two total costs together, which is $23.10+$16.80=$39.90

Pavel [41]

Answer:

1. 4

2. y = 4x

Step-by-step explanation:

1.

Divide any y value by its corresponding x value to find the constant of proportionality.

8/2 = 4

Constant of proportionality: 4

2.

Equation of proportional relation:

y = kx, where k is the constant of proportionality.

y = 4x
