First off, we'll convert the mixed fraction to "improper" and check about, keeping in mind that, there are 5280 feet in 1mile.

A=g≈-32
v=⌠a dt since a≈-32
v=-32t+C, where C is the initial velocity, which we are told is 20 ft/s
v=-32t+20
h=⌠v dt
h=-32t^2/2+20t+C, where C is the initial height, so what is a reasonable initial height? How about 3 ft since we are swinging a bat around maybe our waist level... maybe :P
h=-16t^2+20t+3
Your choices may have made a different assumption about the initial height of course but you did not show your choices, but certainly it will be:
h(t)=-16t^2+20t+hi, where hi is the initial height in feet.
This of course ignores air resistance and flight dynamics of a spinning ball with seams, which will make a significant difference in real life :)
Answer:
18.04 gallons
Step-by-step explanation:
The cost of filling the empty tank of the vehicle is $71.98.
If each gallon of gas costs $3.99, then we have to find the volume of the sedan's tank in gallons.
Now, $3.99 is the cost of 1 gallon of gas.
Hence, $71.98 will be the cost of
gallons.
Therefore, the volume of the tank is 18.04 gallons. (Answer)
Answer:
5% did not pass inspection
Step-by-step explanation:
Given


Required
Determine the percentage of parts that didn't pass inspection.
First, we need to calculate the number of those that didn't pass inspection.



Next, we calculate the percentage as follows:

The above formula is derived by dividing the number of parts that didn't pass inspection by the total machine inspected, then multiplied by 100%
So:




<em>5% did not pass inspection</em>
Answer:
Step-by-step explanation:
The formula for determining the area of a rectangle is expressed as
Area = 2(L + W)
Where
L represents the length of the rectangle.
W represents the width of the rectangle.
A proper rectangle has a length of 6 inches and a with of 8 inches. The area of the rectangle would be
6 × 8 = 48 inches^2
A square with a side length of 3 inches was cut of it. The formula for determining the area of a square is l^2
Therefore,
Area of square = 3^2 = 9 inches ^2
The area of the remaining paper would be
48 - 9 = 39 inches^2
