I think you are referring to this:
The volume of the sink shaped like a half sphere is [2000/3] π in^2.
A. The volume of a cylinder =area of the base * height
For this part the cup has a diameter, d, of 4 in and height, h, of 8 in.
[2000 / 3]π / [32π] = 20.83
Answer: 21 cups.
B. For this part the diameter of the cup is 8 in and the height is 8 in
And the number of cups needed is [2000π/3] / (128π) = 5.2
Answer: 5 cups
Take both mixed numbers (a whole number plus a fraction) and turn them into improper fractions ( a numerator (top number) bigger than the denominator (bottom number). To do this, multiply the denominator by the whole number, and add the result to the numerator.
5 5/8 will become 45/8
1 1/2 will become 3/2.
Area is length* width, so width would be Area/ length. So 45/8 is the area and 3/2 is the length. Now you have (45/8)/(3/2). To divide fractions, take the second fraction and flip the numerator and denominator, forming the reciprocal (2/3). Now multiply 45/8 and 2/3
The result is 90/24, and simplifying would get 15/4, or 3 3/4. This is the width(or length)
Answer:
10 is maximum of packages of quesadillas.
Step-by-step explanation:
x= number of wings
y= number of quesadillas
x+y=20
8x+10y=$160
if x=7
then 7+y=20
20-7=14=y
14*10=140
8*7=56
Rasheed can't buy 20 packages, since it'll go over his budget.
So 160-56=104
And 104/10= 10 minimum
10*10=100
100+56=160
So he can buy 10 packages of quesadillas.
Answer:
you are correct
Step-by-step explanation:
5 - 2(x + 2)
Since parenthesis comes first in PEMDAS, distribute 2
5 - 2x - 4 = 1 - 2x
