Ok so you will be finding the perimeter of this rectangle. The formula is P(perimeter)=2L(length) + 2W(width)

so the length is 48 and the width is 1/2 of 48, and we all know that 1/2 of 48 = 24 right? so in the formula is says 2L so we will take 48 and multiply it by 2 and get 96. The same way with the width. 24 times 2 = 48 so then we add them together and get 144. Therefore the perimeter and the length of fringe that she will use (or how ever you say it) will be 144 inches.

Hope this helps!;)

The Jones family has 3 children.
Lubov Fominskaja [6]
Amy = x
Betty = y
Carl = z
x + y = 29
x + z = 27
y + z = 22
y = 29 - x
z = 27 - x
29 - x + 27 - x = 22
-2x + 56 = 22
-2x = - 34
x = 17
y = 12
z = 10
Oldest child is Amy (17) and youngest child is Carl (10)
17 - 10 = 7
The difference between oldest child and youngest child is 7 years.

GalinKa [24]

Answer:

9 cards.

Step-by-step explanation:

Given:

Yasmine needs to create invitations for the party.

She has ¾ of an hour to make the invitations.

It takes her 1/12 of an hour to make each card.

Question asked:

How many invitations can Yasmine create?

Solution:

Yasmine takes \frac{1}{12} hour create number of cards = 1

Yasmine takes 1 hour to create number of cards = \frac{1}{\frac{1}{12} }=1\div\frac{1}{12}=1\times\frac{12}{1} =12

Yasmine takes \frac{3}{4} hour to create number of cards = 12\times\frac{3}{4} =\frac{36}{4} =9

Therefore, Yasmine can create 9 cards.

If B is the midpoint of AC and the length of AC is 23.8 what is the legength of AB
swat32
Hey there,

So explain and to illustrate (how B is the midpoint of AC and the length of AC is 23.8 what is the length of AB

<span>                                       A-----------------B----------------C
</span>
So, \boxed{AC} in the problem here is to be considered the (Whole area of this line). AC is the whole thing. 

So, what we do in this problem, we do . . .

23.8 ÷ 2 because we need to find what is AB, so we will find the one half of it, which in this illustration is to be considered AB

23.8 ÷ 2 = \boxed{11.9}

\boxed{AB=11.9}

Hope this helps.
