Answer:
The height of the shipping carton is
9in
Step-by-step explanation:
This problem bothers on the mensuration of solid shapes. Rectangular prism.
Given data
Volume of prism = 90in³
Area of base = 10in²
We know that the volume of a rectangular prism is expressed as
V= l*w*h
Where l= length
w= width
h= height
But our given area = l*w=10in²
Substituting our given data we have
V= A*h
90=10*h
h=90/10
h= 9 in
Answer:
it would be 0.01530612244
Your answer is 3/16 I think this is accurate for the problem
Answer:
The new coordinates are (-11, -35)
Step-by-step explanation:
When reflecting across the x-axis, you are just the Y. value. It is the opposite due to the fact that if you're moving something across the horizontal x-axis, it's actually the vertical height changing. So, you just inverse the Y value to its' negative or positive reciprocal.
Answer:
Step-by-step explanation:
Let b
Bill's rate of travel = x
Let Julie's rate of travel = 3x
The time each travels is 2.5 hours
Together they travel a distance of 190 miles
d = r*t
Bill's distance covered is r * t = 2.5x
Julie's distance travel is 2.5 * 3x = 7.5x
The total distance = Bill + Julie
2.5x + 7.5x = 190
10x = 190
x = 190/10
x = 19
Bill's distance = 2.5 * 19 = 47.5
Julie's distance = 19 * 7.5 = 142.5
Rate = distance / time
Bill's rate = 47.5 / 2.5 = 19 miles per hour.
Julie's rate = 142.5/2.5 = 57 miles per hour
Is there an easier way?
You should notice that Bill's rate is just x which is 19 miles / hour
You can also notice that Julie is going 3 times as fast or 19*3 = 57
