How do you use the product of 123 times 47 to find the product of 123 times 0.47 explain the difference in the two products?
iragen [17]
123•47=5781
123•0.47=57.81

you can use the product of 123•47 to help you solve for the product of 123•0.47 by seeing that all you do is move the decimal yo the left 2 spaces. The reason you move the decimal to the left 2 spaces is because 47 is 0.47 just the decimal was moved 2 spaces to the right.

there are 3 people who work full-time and are to work together on a project but their total time on the project is to be equival
mina [271]

The problem express that the fraction of time worked by the three people need to be equivalent to one person working full time. This means that the fraction need to add up to one. We know one person works ½ time on the project and another works one third 1/3 time.

Given:

A = the amount of time that the third person needs to work on the job to add up to one

1 = ½ +1/3 + A

1 – ½ - 1/3 = A

To subtract the fractions put them all over a common denominator. Use 3 * 2 as the denominator.

1=6/6, ½ = 3/6, 1/3 = 2/6

A = 6/6 – 3/6 – 2/6

<span>A = 1/6 , The third person  must work on the project</span>

Do you know the inequality? Please explain and show answer :)
DerKrebs [107]
If u have a open circle, then the inequality has no equal sign. But if it is a closed circle, the inequality has an equal sign.
Shading to the left means " less then " .
Shading to the right means " greater then " .

(1) u have an open circle on -7 with shading to the left....
     x < -7

(2) u have a closed circle on 4.5 with shading to the left....
    x < = 4.5 (thats less then or equal)

(3) u have an open circle on -5 with shading to the right...
     x > -5

(4) u have an open circle on 1.5 with shading to the right...
     x > 1.5

A square has a side length of at+b. What is the perimeter of the square if t =c,simplified? A=7 B=10 C=9
EastWind [94]

The perimeter would probably be 292 because at+b is 7(9)+10, or 73 and there are 4 sides of a circle, so 73 times 4 is 292.
