Answer:
The dimensions of the screen are
Length:102 feet
Width: 82 feet
Step-by-step explanation:
we know that
The area of the rectangle (movie screen) is equal to

where
L is the length
W is the width
we have

so
----> equation A
The screen is 20 feet longer than it is wide.
so
---> equation B
substitute equation B in equation A

solve for W

solve the quadratic equation by graphing
the solution is W=82 ft
see the attached figure
Find the value of L

therefore
The dimensions of the screen are
Length:102 feet
Width: 82 feet
Answer:
x=6
y=4
Step-by-step explanation:
just find the number that will match or u could just plug in one of those number and find other number
If you change both to a fraction you would see that you have 1/6 and 1/4 (.25 as a fraction). So 1/5 would be in between them.
You could also change both as a decimal. 1/6 =.166666 and .25 so any number in between them would be correct such as .2 which is the same as 1/5.
To convert cm³ to m³, you can break down the units.
cm³ = cm x cm x cm
Each cm is converted to m so :
m³ = m x m x m
= 1/100 x 1/100 x 1/100
= 0.000001
So, 1cm³ is 0.000001m³, so to convert cm³ to m³ you divide your value by 1,000,000 and vice versa.
1. 0.35m³
2. 8m³
3. 43.34m³
4. 30m³
5. 0.77m³
