Answer:
The length is 11ft.
The width is 8ft.
Step-by-step explanation:
Hello!
Perimeter of a rectangle:
- P = perimeter
- l = length
- w = width
We know that the length is 5 ft less than twice the width, which can be expressed by the equation: l = 2w - 5. We can plug in 38 for "P".
We can substitute the equation for l, and solve for the width.
<h3>Solve for W</h3>
The width is 8. We can solve for the length by plugging it back into the equation l = 2w - 5
<h3>Solve for L</h3>
- l = 2w - 5
- l = 2(8) - 5
- l = 16 - 5
- l = 11
The length is 11.
The dimensions are 11 ft and 8 ft.
Answer:
The systems of equation for the amount spent are as follows
Step-by-step explanation:
In this problem we are expect to give a model or an equation that represents the amount of money spent per month given a fix subscription amount and a variable fee which is based on extra minutes spent.
let Y represent the amount of money spent in total for the month
The first case:
Subscription =$5
charges per minutes = $0.99
therefore the amount spent can be modeled as
The second case:
Subscription =$10
charges per minutes = $0.79
therefore the amount spent can be modeled as
Answer:
height = 18m
Step-by-step explanation:
cone volume = 3183.96 m³
1/3 πr²h = 3183.96
1/3×3.14×13×13×h = 3183.96
h = 3183.96×3/13×13×3.14
h = 9551.88/530.66
h = 18
