Answer:
I can't help.
Step-by-step explanation:
There is no question, so therefore, I can not help.
They have enough balloons because I used division as my operation. 3 can go into 16 five times. I got 1 after subtracting and bring down 2. 3 can go into 12 evenly 4 times. 12 minus 12 equals 0 with no remainder. So, they get 54 balloons for each group. But I want to know how many EACH student gets enough balloons. 54 divided by 6 groups equals 9 balloons for each student.

Answer:
7.25cm
Step-by-step explanation:
Let the complete question be;
<em>Jill cuts a piece of cardboard in the shape of a trapezoid. The area of the is 43.5sp cm. If bases are 3.5cm and 8.5cm long, what is the height.</em>
<em />
Area of a trapezoid = 1/2(a+b)*h
a and b are the parallel sides (bases)
h is the height
Given
a = 3.5cm
b = 8.5cm
A = 43.5 sq.cm
Required
Height h
Substitute the given values into the expression
Area of a trapezoid = 1/2(a+b)*h
43.5 = 1/2(3.5+8.5)*h
43.5 = 1/2 * 12h
43.5 = 6h
h = 43.5/6
h = 7.25cm
Hence the height is 7.25cm
