The sides of a triangle are in the ratio 3 : 4 : 5. What is the length of each side if the perimeter of the triangle is 90 cm?
iogann1982 [59]
What we can do is set up an algebraic equation. 

our variable can me L for Length

3L+4L+5L=90

now all we have to do is solve

12L=90
----   ----
12      12

L=7.5

now multiple each number in the ratio by 7.5 to find out how long each side is

3 times 7.5 is 22.5
4 times 7.5 is 30
5 times 7.5 is 37.5

the side lengths are 22.5, 30, and 37.5

Answer:

2x + 2x+2 = 3x + 1

4x + 2 = 3x + 1

Subtract 3x from both sides

4x - 3x + 2 = 3x - 3x + 1

x + 2 = 1

Subtract 2 from both sides

x + 2 - 2 = 1 - 2

x = -1

Hope this helped!!!

Ronch [10]

Answer:

So, the population mean is 3.66.

Step-by-step explanation:

We will calculate the average value by summing all the values and dividing by the  size of sample.

We have population contains six members, with values 1,1,2,3,5,10.

Therefore, n=6.  

We use the formula to calculate the population mean:

\mu=\frac{x_1+...+x_n}{n}\\\\\mu=\frac{1+1+2+3+5+10}{6}\\\\\mu=\frac{22}{6}\\\\\mu=3.66

So, the population mean is 3.66.
