Answers

Answer 1
Answer:

The percentage of questions Matt has answered is 80 %

What is Percentage?

A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %

Given data ,

Number of questions Matt has answered = 20

Total number of questions = 25

Let the percentage of questions Matt has answered = x


Number of questions Matt has answered / Total number of questions = x %

Percentage of questions Matt has answered = ( Number of questions Matt has answered / Total number of questions ) / 100

                                                                    x    = ( 20 x 100 ) / 25

                                                                    x    = 20 x 4

                                                                    x    = 80 %

Hence, the percentage of questions Matt has answered is 80 %

What is the square root of 65

Answers

one way is factor
exg
if you wanted to find the square root of  36  you would factor
36=2 times 2 times 3 times 3
then group repeeting numbers then write only one of them
36=(2 times 2) times (3 times 3)
squareroot36=2 times 3=6

so factor 65
65=5 times 13
that doesn't help
next step
find squares close to that numbers
1^2=1
2^2=4
3^2=9
4^2=16
5^2=25
6^2=36
7^2=49
8^2=64
9^2=81

the answer is a little more than 8
