Average speed = (distance covered) / (time to cover the distance)
= (500 miles) / (6.7 hours)
= (500 / 6.7) (mile/hour)
= 74.63 miles per hour.
I imagine there were quite a number of pit stops included in that.
This is faster than I expected when I first read your question.
That's really gettin' with it for cars in 1911 !
Answer:
Part A) The system of equations is equal to
Part B)
The length is 
The width is 
Step-by-step explanation:
Part A)
we know that
The perimeter of the triangle is equal to the sum of the length of its three sides
In this problem
-----> equation A
The perimeter of rectangle is equal to
In this problem
------> equation B
Part B)
Using a graphing tool
Solve the system of equations
We know that
The intersection point both graphs is the solution of the system of equations
The intersection point is 
see the attached figure
step 3
Find the length and width of the rectangle
The length is 3x
The width is 7y
Try this option:
using a formula 'V=1/3 * Area_of_base * height' it is possible to find volume of the sand:
V=1/3 * 3 * 5²=25 cm³
Answer:
What percentage of pick-up truck drivers want their next vehicle purchase to be another pick-up truck?
Should the speed limit be decreased on the highway connecting two large cities?
How many pedestrians would use a walkway built over a busy road?
Step-by-step explanation:
We use samples when using an entire population is not feasible.
It is not reasonable to ask every pick-up truck driver what they want their next purchase to be; there are too many owners of pick-up trucks. This means we should use a sample.
Many people drive a highway that connects two large cities. It is not reasonable to survey every person that drives it, so we should use a sample.
On a busy road, we may have many pedestrians; this means we should use a sample instead of the entire population.
A term subtracted by 1, then multiplied by 3.
