Answer:
Percentage of cherries = 60 %
Percentage of berries = 40 %
Step-by-step explanation:
He orders 15 1/2 pounds every year.
He wants more= 1 1/4 pounds
So the total pounds = 15 1/2 + 1 1/4
= 15 + 1 + 1/2 + 1/4
= 16 + (2+1)/4
= 16 + 3/4
= 16 3/4 pounds
Out of 16 3/4 pounds they want 2/5 part to be of blue berries.
So blue berries = 16 3/4 * ( 2/5)
= 67/4 * ( 2/5)
= 67/10 = 6 7/10 pounds
Amount of cherries= 16 3/4- 6 7/10
= 10 3/4- 7/10
= 10 (15- 14)/20
= 10 1/20 pounds
Percentage of cherries = Amount of cherries/ Total amount * 100
= 201/20 / 67/4 *100
= 201/20 * 4/67 *100
= 201/335 *100
= 60 %
Percentage of berries = 100- 60 = 40 %
Answer:
7/200
Step-by-step explanation:
3.5% = 3.5/100 = (3.5/100)×(2/2) = 7/200
_____
The % symbol is a shorthand way to write "/100", so 3.5% = 3.5/100.
Answer:
6n(n - 1)(n^2 - 3n - 3).
Step-by-step explanation:
The GCF = 6n.
6n^4 - 24n^3 + 18n
= 6n(n^3 - 4n^2 + 3)
Putting n = 1 in the expression in the parentheses:
(1)^3 - 4(1)^2 + 3 = 0 so n - 1 is a factor.
Dividing:
n - 1 ) n^3 - 4n^2 + 0n + 3 ( n^2 - 3n - 3
n^3 - n^2
-3n^2 + 0n
-3n62 + 3n
- 3n + 3
-3n + 3
So the factors are 6n(n - 1)(n^2 - 3n - 3).
Answer:
1 student is taking drafting and 13 are taking algebra. None of them do both.
Step-by-step explanation:
9C5 = 9!/[5!(9-5)!
9C5 = 9!/(5!)(4!)
You finish.
7P4 = 7!/(7-4)!
7P4 = 7!/3!
You finish.
