Answer:
36 pencils
Step-by-step explanation:
Let h and p represent the number of highlighters and the number of pencils, respectively.
Then h + p = 45, and h = 45 - p.
Tom paid a total of $30 for these supplies, with ($2/highligher)(h) + ($0.333/pencil) adding up to that amount.
substituting 45 - p for h in 2h + 0.333p = 30, we get:
2(45 - p) + 0.333p = 30, or
90 - 2p + 0.333p = 30
Combine the constants: 60 = 2p - 0.333p, or 60 = 1.667p
Then p = 60/1.667 = 35.9928, or 36.
Tom bought 36 pencils for $12, and 45-36, or 9, highlighters for $18, for a total purchase of $30. This shows that these calculations are correct.
The correct answer is 16/81. Hope this helps.
(2/7)^2 x (7/9)^2
((2^2)/(7^2)) x ((7^2)/(9^2))
(4/49) x (49/81)

Answer:
66%
Step-by-step explanation:
Given :
Age Percentile
75 97
65 90
55 78
45 58
35 37
25 13
20 66
To Find :The percentage of drivers who are younger than 20 is _____%.
Solution:
Refer the given table
The percentile corresponding to age 20 is 66.
Percentile : A data item is said to be in nth percentile of distribution if n% of the distribution are less than that particular data item.
So, drivers who are younger than 20 are said to be in 66 percentile if 66%of the distribution are less than that particular data item.
Hence The percentage of drivers who are younger than 20 is 66%.
Answer:
C
Step-by-step explanation:
It is the exact opposite because when you divide by 4 you go lower and when you multiply by 4 you go higher, thus making them inverse operations
