Jack is driving from his house to the airport. at 9: 00 am, he is 150 miles from the airport. at 10: 30 am, he is 75 miles from the airport. what is jack’s average driving speed between 9: 00 am and 10: 30 am?
miles/hour

I b3live it is 50 miles/hour

Step-by-step explanation:

We need to know how many miles he drove from 9:00 to 10:30 so you do 150-75 which is 75. Then, you do 75÷1.5 because 9:00 and 10:30 are an hour and a half apart and then you get 50 mph.

the answer is  

a.

4,624π mm2

step-by-step explanation:

“ a line segment that has the endpoints on the circle and passes through the midpoint is called the diameter. the diameter is twice the size of the radius. a line segment that has its endpoints on the circular border but does not pass through the midpoint is called a chord. a circle is the same as 360 small circle up the number 0 . i hope this .
