Answer: 
is needed for 5 servings.
Step-by-step explanation:
Since we have given that
Hemal wanted to make desert for her family for which they made the recipe,
For 8 servings , the number of cups of flour is needed = 2
We will use "Unitary Method" ,
For 1 serving, the number of cups of flour is needed is given by
For 5 servings, the number of cups of flour is needed is given by
Hence, is needed for 5 servings.
Let's the length to be x,
then the width is 8x - 2.
Perimeter of a rectangle = 2*Width + 2*Length
Perimeter of the rectangle = 2(8x-2) + 2x = 16x - 4 + 2x = 18x - 4
Ar the same time, Perimeter of the rectangle = 88.
So, we can write
18x - 4 = 88
18x = 84
9x=42
x= 42/9 cm (length) or ≈ 4.67 cm (length)
8x - 2 = 8*42/9 - 2 ≈ 35.33 cm (width)
The answer is 16 pi or about 50.27
Answer:
= 18 red marbles
Step-by-step explanation:
Let x be the number of red marbles that must be added
Therefore;
New number or red marbles = x+12
Total marbles will be x+32
Thus;
The probability of selecting a red marble = (x+12)/(x+32)
Therefore;
(x+12)/(x+32)=3/5
5(x+12)=3(x+32)
5x+60+3x+96
2x=36
x=18
