radicals and percents help?

Question

please show me how to do work, and the correct answer, if possible :]
the square root of 3 x the square root of 3 =?

square root of 100=?

125% of 600=?

40% of 70=?

90% of 40=?

5%of 80

Answer 1

square root of 100=10 (10x10=100)

125% of 600=750 (1.25x600)

40% of 70= 28 (2/5x70)

90% of 40= 36 (9/10x40)

5%of 80= 4 (1/20x80)

Answer 2

the square root of 3 x the square root of 3 =3

square root of 100=+/-10

125% of 600=750

40% of 70=28

90% of 40=36

5%of 80=4

Answer 3

the square root of 3 x the square root of 3 =3 since (3)^.5*(3)^.5=(3)^.5+.5=(3)^1=3

square root of 100=? = 10 10*10=100


125% of 600= 1.25*6= 7.50

40% of 70=.4(70)=2.8

For any x% of y => x/100* y....that simple

Answer 4

square root of 100=10

125% of 600=750

40% of 70=28

90% of 40=36

5%of 80=4

Answer 5

square root of 100=? 100^(1/2)=10

125% of 600=?1.25*600=750

40% of 70=?.4*70=28

90% of 40=?.9*40=36

5%of 80 .05*80=4

Answer 6

sqrt(3) * sqrt(3) = sqrt (3*3) = sqrt(9) = 3

sqrt(100) = 10 because 10 times 10 = 100
125% of 600= 1.25 times 600 = 750
[To change % to decimal replace % sign with decimal point and then move thedecimal point 2 places to the left]
40 % of 70 = .4(70)=28
90% 0f 40 = .9(40) =36
5% 0f 80 = .05(80) = 4

Answer 7

A percent is just that number over 100. So 5% is 5/100. Multiply whatever number you are seeking the percent of by the fractional form of the percent and you can find the percent of that number.

Answer 8

SQUARE ROOT OF 3 CAN BE REPRESENTED AS 3 TO THE 1/2 POWER
THE RULE FOR MULTIPLYING LIKE BASES IS TO ADD EXPONENTS.
3^1/2 TIMES 3^1/2 IS 3^1 WHICH IS 3

2--ASK YOURSELF WHAT # TIMES ITSELF WILL BE 100
10
3--4-5 &6--CHANGE TO DECIMAL AND MULTIPLY
% MEANS .00---MOVE DECIMAL TWO PLACES TO LEFT
40 % IS ,4 AND SO ON

Answer 9

Hi how are you I'm not good with math my dear but I can give you a site that may be able to help you to understand this quotetation of math. I hope this sites are able to guide you no matter what even for future questions.
