9 cups of milk would be needed to make 99 cookies
If 1 cup = 11 cookies then...
99 (cookies we need to make) divided by 11 (cookies each cup) we get 9.
I hope this helps!
This is the concept of perimeter of geometric figures;
We are required to approximate the perimeter of the triangle given if JA=10, AL=23, CK=9
Summing the above measures we get;
10+23+9=42
assuming that this is half the perimeter of the whole triangle then;
perimeter=2*42=84
The answer is A
The equation is to be given, judging by the tone problem given but apparently it's not given. The equation can be derived from the problem. The area of a trapezoid is given by the equation
. Also, given that a, is the longer side, then a = h+7 and b (shorter side) = h+3 and h is the height. the equation is then
. Solving this quadratic equation, h is 4.84.
