Answer:
About 2.17 feet.
Step-by-step explanation:
Let <em>d</em> represent the diameter of the tire.
Then the circumference of the tire will be:

So, the tire will travel dπ miles after one rotation.
After 775 rotations, the total miles traveled should be 5280 feet. Thus:

Solve for <em>d:</em>
<em />

Approximate:

The circumference of the tire should be about 2.17 feet.
The value of given expression when x=-4 and y=4 is 1250.
The expression is missing in the question which is
.
We have to solve it for x= -4 and y = 4.
Now putting the value of x and y we get,



Hence the value of given expression when x=-4 and y=4 is 1250.

Answer:
29.2 percent decrease
Step-by-step explanation:
the difference between 96 and 68 is 28 bucks
28 is what percent of 96
is over of
x/100 x 28/96
cross multiply=2800/96
divide 2800 by 96 and the answer is 29.1666
Given:
A space shuttle can travel at 28968 km/h.
To find:
The distance it can cover in 8 hrs.
Solution:
We have,
Speed of space shuttle = 28968 km/h.
So,
Distance covered by the space shuttle in 1 hour = 28968 km/h.
Distance covered by the space shuttle in 8 hour = (28968 × 8) km
= 231744 km
Therefore, the distance it can cover in 8 hrs is 231744 km.
