Looks like you meant to write (p/q)³ if so it's power of a quotient

Answer:

Let's suppose you meant $(\frac{P}{Q} )^3$

If that is true, we would apply power of a quotient.

Step-by-step explanation:

The law about power of a quotient defines: "the power of a quotient is equal to the quotient obtained when the numerator and denominator are each raised to the indicated power separately, before the division is performed".

The principal at valley elementary school had 840 stickers that he gave to 42 children. 2/3 of the children were boys and each o

STatiana [176]

Answer: each girl received 30 stickers.

Step-by-step explanation:

Let x represent the number of stickers that the boys received.

Let y represent the number of stickers that the girls received.

The total number of children was 42. 2/3 of the children were boys. It means that the number of boys were

2/3 × 42 = 28

The number if girls would be

42 - 28 = 14

The total number of stickers that the school principal shared was 840. It means that

28x + 14y = 840- - - - - - - - -1

Each of the boys received the same number of stickers while each girl received twice as many as each boy. It means that

y = 2x

Substituting y = 2x into equation 1, it becomes

28x + 14 × 2x = 840

28x + 28x = 840

56x = 840

x = 840/56

x = 15

y = 2x = 15 × 2

y = 30

Look at the figure below; what additional information do you need to have to determine if segment DE is the midsegment?

77julia77 [94]

1. If you knew that DE = $\frac{1}{2}$ CB
Then you would know it is a mid-segment.

2. If you knew that CD = DA and BE = EA (point D and point E are midpoints of their respective segments)
