At a hardware store, they can cut a length of rope off of a big roll, so you can buy any length you like. The cost for 6 feet of rope is $7.50. How much would you pay for 50 feet of rope, at this rate?
Answers
Answer:
It should be 62.5 or 62.50.
Step-by-step explanation:
Here's why..........it would be very difficult to it another way so here is what I did....you have to find out how much 1 foot would cost which was 1.25 then multiply that by 50 and you will get 62.50.
Keelin's hourly rate went from $9.50 per hour to $10.25 per hour. What
is the percent increase?
Answers
The percentage increase in the hourly rate will be 7.89%.
What is the percentage?The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.
Given that Keelin's hourly rate went from $9.50 per hour to $10.25 per hour.
The percentage increase will be calculated as:-
Percentage increase = ( 10.25 - 9.50 ) / 9.50
Percentage increase = 0.75 / 9.50
Percentage increase = 0.0789 x 100
Percentage increase = 7.89%
Hence, the percentage increase is 7.89%.

if z varies jointly with w, x, and y. z=24 when w=2, x=3, and y=8 then z=1/2wxy
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given,
z varies jointly with w, x, and y
z=kwxy
Where k is constant.
k=z/wxy
Now plug in values of z=24, w=2, x=3, and y=8.
k=24/2.3.8
k=24/48
k=1/2
So z=1/2wxy
Hence, if z varies jointly with w, x, and y. z=24 when w=2, x=3, and y=8 then z=1/2wxy
