Answer:
1. The time it would take Inex to run 1 mile is 5 minutes 20 seconds
2. Great has the fastest (lowest) time
3. When running a mile Great is faster than Inex by 20 seconds
Step-by-step explanation:
1. The distance Great ran in 5 minutes = 1 mile
The distance Inex ran in 1 minute and 20 seconds = A quarte mile = (1/4) mile
We note that 1 minute and 20 seconds = 4/3 minutes
Given that the time Inex ran 1/4 mile = 4/3 minutes...(1)
We have;
The time it would take Inex to run 1 mile is given as follows;
1 = (1/4) ÷ (1/4)
1 mile = ((1/4) ÷ (1/4)) mile = (1/4) mile/(1/4)
The time to run 1 mile = The time to run (1/4) mile/(1/4) = 4/3 minutes/(1/4) (by dividing both sides of equation (1) by (1/4),
4/3 minutes/(1/4) = 4 × 4/3 minutes = 16/3 minutes = [tex]5\frac{1}{3}[/tex] minutes= 5 minutes 20 seconds
The time it would take Inex to run 1 mile = 5 minutes 20 seconds
2. Given that Great ran a one mile race in 5 minutes, and Inex ran the same one mile race in 1 minute and 20 seconds, Great has the fastest (lowest) time
3. The amount faster Great's time is faster than Inex's time to run one mile = 5 minute 20 seconds - 5 minutes = 20 seconds.

A salesman earns 20% commission on all the merchandise that he sells. Last month he sold $900 worth of merchandise. How much commission (in dollars) did he earn last month?
Answer: $180
Step-by-step explanation:
Given
Salesman earns 20% commission on merchandise he sells
Last month sales by him are $900
So, his commission out of $900
[tex]\Rightarrow 20\%\ \text{of}\ 900=0.2\times 900\\\Rightarrow \$180[/tex]
So, he grabbed $180 dollar as commissions

Answer:
C) 4(5c -2d)
Step-by-step explanation:
You would need to find the greatest commen factor in the equation.
it would end up being 4 since it is the biggest number that can divide between 8 and 20.
20/ 4 = 5
8/4 = 2
so you would leave the varibles since you can't take them out and put 4 on the outside of the parantheses.
4(5c -2d)

A sculpture is in the shape of a cylinder. The sculpture has a diameter of 10 feet and a height of 21 feet. Which measurement is closest to the total surface area of the sculpture in square feet?
Answer:did u get the answer?
Step-by-step explanation:sorry
The measurement of total surface area of the sculpture in square feet is 814 square feet.
What is the surface area of a cylinder?The surface area of a cylinder can be calculated by adding the area of its lateral surface to the sum of the areas of its two circular ends. The formula for lateral surface area is given by: 2πrh
where r is the radius of the circular base and h is the height of the cylinder.
Since the diameter of the cylinder is 10 feet, the radius is 10/2 = 5 feet.
So, the lateral surface area of the cylinder = 2 × π × 5 × 21 = 210π square feet.
The area of each circular end is given by πr². Since the radius is 5 feet, the area of each circular end is π × 5² = 25π square feet.
Therefore, the total surface area of the cylinder is 210π + 2 × 25π = 260π square feet.
The value of π is approximately 3.14, so the surface area of the cylinder is approximately 260 × 3.14 = 816.4 square feet.
So, the closest measurement of the total surface area of the sculpture in square feet is 816 square feet.

Both gliders reach the same altitude on the given interval.
Neither glider reaches a maximum altitude on the given interval.
OD
Answer:
Robbie's glider
Step-by-step explanation:
Robbie reaches the greater maximum altitude in the first 6 seconds after launch option (C) Robbie's glider is correct.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
It is given that:
Melissa and Robbie are flying remote control gliders.
The altitude of Melissa's glider, h(s), in feet, is modeled by this function:
m(s) = 0.4(s³ - 11s² + 31s - 1)
Plug s = 6 seconds in the function m(s)
m(6) = 0.4(6³ - 11(6)² + 31(6) - 1)
m(6) = 0.4(216 - 396 + 186 - 1)
m(6) = 0.4(5)
m(6) = 2 feet
From the graph of Robbie:
At s = 6 seconds
Altitude = 13 feet (approximately)
Thus, Robbie reaches the greater maximum altitude in the first 6 seconds after launch option (C) Robbie's glider is correct.
