z varies jointly with w, x, and y. z=24 when w=2, x=3, and y=8.
Answer:29739
Step-by-step explanation:
neosbs elenelend sidn
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

Keelin's hourly rate went from $9.50 per hour to $10.25 per hour. What
is the percent increase?
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%.

Answer:
2/3 cups
Step-by-step explanation:
if we put all ingredients toghether will have
1/4+2/3+1 and 1/3=1/4+1 and 2/3+1/3=1/4+ 2= 2cups and 1/4 or 2.25 cups
So 2.25 cups is 1 batch of dressing
6 cups is x batches of dressing
cross multiply x=6*1/2.25= 6/2.25
so insted of 1/4 vineger will need (1/4)(6/2.25)=6/9=2/3 cups of vinegar

Find the volume of a right circular cone that has a height of 17.6 m and a base with a
radius of 8 m. Round your answer to the nearest tenth of a cubic meter.
Answer:
1179m^3
Step-by-step explanation:
Given radius=8m
Height=17.6m
Volume of the cone=1/3πr^2h
1/3 πr^2h
=1/3×3.14×8×8×17.6
=1178.96
Nearest tenth is 1179
So volume is 1179m^3
