Answer:
32 ft
Step-by-step explanation:
find the area of the large rectangle:
30 x 16 = 480
find the area of the small rectangle:
10 x 8 = 80
subract the small rectangle from the big rectangle to get the area of the shaded region:
480 - 80 = 400
now plug this area and the height into the equation for triangle area:
A = bh/2
400 = b(25)/2 multiply both sides by 2
2(400) = 2(25b/2)
800 = 25b divide both sides by 25
800/25 = 25b/25
32 = b
150p
To find the cost of one pen, do 60/2
So 30p/ pen
Just multiply this value by 5 :)
30 x 5= 150
Most of the information's are already given in the question. It is important to understand the language of the problem for solving the problem. Once the language is understood, then solving the problem is easy.
Let us assume the number of black jelly beans = x
Number of yellow jelly beans = y
Then from the question we can get to a equation.
3x - 7 = y
We also know from the question that
x + y = 225
x + 3x -7 = 225
4x = 225 + 7
4x = 232
x = 232/4
= 58
So Cassidy has 58 black jelly beans out of the total of 225 jelly beans
The answer to your question is -1 < y < 3
