Answer:

54

Step-by-step explanation:

120 x .45 = 54; and to check

54 ÷ 120 = 0.45

First you move the decimal point to the right 2 spaces to change the percent (%) to a decimal (change 45% to .45); and then you multiply by the 120. So it turns into

.45 x 120 = 54 the answer is: 54

To check you go in the opposite direction.  Move the decimal point to the right ( 45 x 120 ) and the answer is 5400; which is a whole number, which means the decimal is invisibly at the end; then move the decimal point back two spaces to the left and it now looks like this 54.00; which is a whole number and the two zeros at the end can be taken off; there's that invisible decimal that makes it a whole number that you p.s. don't ever need...  You are right back to 54 :)

Hope that helps! <3

Answer:

83.3%

Step-by-step explanation:

The probability of rolling a 3 on a 6-sided dice is 1/6

Since you don't want a three, there's a 5/6 chance of not rolling a 3

5/6 (use calculator and divede 5 by 6) = 0.833333 (move decimal 2 to the right) = 83.3%

Therefore, the most reasonable answer would be C, 83.3%

Simplify this number 300mm:9m​
DIA [1.3K]

Answer:

1 : 30

Step-by-step explanation:

300mm:9m​

We need to change the meters to mm

1 meter is 1000 mm

so 9 m is 9000 mm

300mm:9000mm

Divide both sides by 300

​300mm/300 : 9000/300

1 : 30

babymother [125]

Answer:

x =±2 sqrt(6)

Step-by-step explanation:

x^2 = 24

Take the square root of each side

sqrt(x^2) = sqrt(24)

x = ±sqrt(4*6)

x =±sqrt(4) sqrt(6)

x =±2 sqrt(6)
