Answer: 0.78 and 39/50
<h3>
Explanation:</h3>
What we know:
- We need to find 78% as a fraction and decimal
How to solve:
The decimal is easy enough, and then the fraction can be found from there. D will represent decimal, p will represent percentage, and F will represent fraction.
<h3>
Process:</h3>
Decimal
Set up equation D = p / 100
Substitute D = 78% / 100
Simplify D = 0.78%
Remove % sign D = 0.78
Fraction
Set up equation F = p / 100
Substitute F = 78% / 100
Remove % sign F = 78 / 100
Simplify if needed F = /2 /2
F = 39 / 50
Solution: 0.78 and 39/50
Check:
Multiply the decimal by 100 to check the decimal
0.78 x 100 = 78; 78%
Divide the fraction to check the fraction
39/50 = 0.78; see above
If the diameter is 2 and the radius is 1 then the volume is V = 2.0943951 m^3
In this problem, we need to solve for the measurement of the width of the rectangular prism on which the formula is Volume = length * width * height. Ther are given values such as length = 3.2 inches, height = 9.6 inches and volume = 138.24 cubic inches. Solving for the width, we have shown it below:
Volume = length * width * height
138.24 = 3.2 * width * 9.6
138.24 / (3.2*9.6) = width
4.5 inches = width
The answer is 4.5 inches for the width of the rectangular prism.
Answer:
Width also known as (W) = 1.5 meters
Area also known as (A) = 6 square meters
Length also known as (L) = ?
the formula to find Length is:
Step-by-step explanation:
Choice 3 is the answer
1.5x = 6
x=4
substitute 4 for the x
1.5(4)=6
1.5×4 = 6
so
6=6
so the answer is
1.5x=6
x=4
