Answer:
12.75
Step-by-step explanation:
The computation of the geometric mean of sqrt 77 and sqrt 343 is given below:
As we know that
Geometric mean = 
where
a is the first number = 
And, the b is the second number = 
Now first we have to convert into a number
For a it, is = 8.78
And, for b, it is = 18.52
Now the geometric mean is
= 12.75
Answer
Area: 3,818
Perimeter: 258
Type: Rectangle
Solution
To find the Area you have to do
Length x Width
so it is 83 times 46 which is 3818
To find Perimeter it is
Length + Length + Width + Width
or 83 + 83 + 46 + 46 = 258
For type i don’t know so probably the type is rectangle
Volume of a cube = a³ = 1728
a = ³√1728
a = 12 mm
In short, Your Answer would be 12 mm
Hope this helps!
Well first you need to find the LCM (least common multiple) of 4 and 6 (the denominators) so that you can subtract them from each other.
4: 4,8,12,16,20
6: 6, 12, 18, 24
The LCM is 12.
Now we can subtract the two mixed numbers by turning them into improper fractions.
5 3/12 -> 27/12
3 10/12 -> 42/12
42-27=15
The fraction is 15/12, which simplifies into 1 1/4.
She cut off 1 1/4 feet of the board.
<u>EXPLANATION </u>
First you will need <u>TWO</u> numbers. One being the percentage and the other being the number your trying to find the percent out of.
<u>EXAMPLE</u>
Imagine you have 130 crayons. Out of the 130 crayons you found that 15% of them were broken.
First you want too take the 15% and put it over 100, because a percentage always goes over 100. Now that you have the 15/100 you now wanna take the 130 crayons and put the variable <u>X</u> over it. Now that you have the fractions 15/100 and X/130 you want to cross multiply them to get <u>100x </u>and <u>1950</u>. For the final step your going to want to take 1950 and divide it by 100 to get your answer, <u>19.5</u>.
I hope this helped you find out the method for solving a percentage problem while using proportions.
