Answer:
Karen needs to spend $4.5 to buy new hair bands.
Step-by-step explanation:
Given:
Hair bands Karen have = 3
cost of 8 hair bands = $1
Total Hair bands she require = 39
Hence Number of of new hair bands require = Total Hair bands she require - Hair bands Karen have = 39 -3 = 36
we need to find how much money she need to spend to buy new hair bands.
cost of 8 hair bands = $1
Cost of 36 hair bands = money need to spend on hair bands
By using Unitary method we get;
Money spend on new hair bands =
Hence,Karen needs to spend $4.5 to buy new hair bands.
Any locker with a number that is a multiple of 8, 12, and 75 will contain all three animals.
The least common multiple of these three numbers is
and so any multiples of 600 between 1 and 3500 will contain all three animals. These are 600, 1200, 1800, 2400, and 3000.
Why is the LCM 600? You can determine that using the prime factorizations of the three given numbers:
The LCM can be obtained by multiplying as many prime numbers together as are needed to contain the prime factorizations of the three numbers. This is obtained with
(at least three 2s to get the 8; at least one 3 and two of the previous 2s to get 12; and at least two 5s along with the previous 3 to get 75)

Answer:
D.) 10/11
Step-by-step explanation:
Here the given word Probability has 11 letters in it. And we have to calculate the Probability of not selecting a letter P from the above word.
So the formula for calculating any probability is Total Favorable outcomes / Total number of outcomes.
Here total number of outcomes are 11 as word Probability has 11 letters.
So the probability of selecting letter P from word Probability =
Now the P(not P) = 1 - P(selecting letter P)
= 1 - =
