To find that , divide the estimate by the actual weight and multiply by 100.
8/6*100=133.33%(rounded)
Therefore the percent error is 133.33%.
Answer:
![3x^2 + 15x - 252 = 0](https://tex.z-dn.net/?f=3x%5E2%20%2B%2015x%20-%20252%20%3D%200)
Step-by-step explanation:
The volume of the prism is 252 cubic centimeters.
The volume of a rectangular prism is gotten by the formula:
V = l * w * h
where l = length
w = width
h = height
The height of the prism is 3 cm.
Let x be the width of the prism.
The length of the prism is 5 cm longer than the width.That is:
l = 5 + x
The volume of the prism is therefore:
V = (5 + x) * x * 3
![=> 252 = (5x + x^2) * 3\\\\252 = 15x + 3x^2\\\\=> 3x^2 + 15x - 252 = 0](https://tex.z-dn.net/?f=%3D%3E%20252%20%3D%20%285x%20%2B%20x%5E2%29%20%2A%203%5C%5C%5C%5C252%20%3D%2015x%20%2B%203x%5E2%5C%5C%5C%5C%3D%3E%203x%5E2%20%2B%2015x%20-%20252%20%3D%200)
This is the equation that models the volume of the tray in terms of x.
Answer:
Angle 1 = 10 degree, Angle 2 = 170 degree
Step-by-step explanation:
m1 + m2 = 180 degree
(x - 24) + 5x = 180
6x - 24 = 180
6x = 204
x = 34
m1 = x - 24 = 34 -24 = 10 degree
m2 = 5x = 5(34) = 170 degree
Answer:
80
