Check my calculations, please.
1/4 mile = .25
11.11 sec. = .003086 hrs.
rate * time = distance
distance / time = rate
.25 / .003086 = 81.0110 = 81 mph.

Question 1169313: For most products, higher prices result in a decreased demand, whereas lower prices result in an increased demand (economists refer to such products as normal goods). Let
d = annual demand for a product in units
p = price per unit
Assume that a firm accepts the following price - demand relationship as being a realistic representation of its market:
d = 800 10p
where p must be between $20 and $70.
a. How many units can the firm sell at the $20 per-unit price? At the $70 per-unit price?
b. What happens to annual units demanded for the product if the firm increases the per unit price from $26 to $27? From $42 to $43? From $68 to $69? What is the suggested relationship between per-unit price and annual demand for the product in units?
c. Show the mathematical model for the total revenue (TR), which is the annual demand multiplied by the unit price.
d. Based on other considerations, the firm’s management will only consider price alternatives of $30, $40, and $50. Use your model from part (b) to determine the price alternative that will maximize the total revenue.
e. What are the expected annual demand and the total revenue according to your recommended price?

Question 1169801: A well-known fact is that a negative number multiplied by a negative number yields a positive number, or, in other words, that (−1)(−1)=1. When asked to justify this, three students reasoned as follows:
Student 1:
" Take the number line. Subtracting the smaller from the larger should give us the distance between two numbers. Now consider 0 and −1 on the number line.
The distance between them should be 1. So we have that
0−(−1)=1⟹−(−1)=1⟹(−1)(−1)=1
This proves the claim."

Question 1169943: A bearing for a roller is .4 inches in diameter and .9 in. in length. The bearings are made from a material weighing 500 lbs. per cu. ft. Determine number of bearings in a 100 lb. container.
Check my calculations, please.
The bearing are cylinders. (I think).
Cylinder volume: Pi * r^2 * height (or length).
3.1416 ^ .2 * .2 * .9 = .11309 cu. in.
1728 cu. in. = 1 cu. ft.
.11309 cu. in. = .00006545 cu. ft.
.00006545 * 500 = 56.54 = 55 lbs.

55 * 100 = 5500 bearings.

Question 1169980: A pipe 8 in. in diameter is transporting water at 48 ft. per min. Determine amount (gal.) will pass a certain point per hr.
A pipe is a cylinder.
Check my calculations, please.
Volume = Pi * r^2 * length
3.1416 * 4 * 4 * 576 = 28952.98 = 28953 cu. in.
231 cu. in. = 1 gal.
28953 / 231 = 125.337 = 125 gal.
125 * 60 = 7500 gal. per hr.
