Answer:
56
Step-by-step explanation:
Given that Lydia is painting flower vases.
Paint required for painting one flower case = 3/16 quart
total paint available with Lydia = 21/2 quart
We have to find the no of flower cases that can be painted.
This is a problem of direct variation since when no of flower cases increase paint required also increases.
3/16 quart for 1 flower case
Hence 21/2 quart for 21/2 divided by 3/16
= 21*16/(3*2) (by rule for fraction division)
= 7(8)
= 56
The probability that both the husband and wife are hired is 
<u><em>Explanation</em></u>
Total number of people = 11 and total number of sales positions = 5
So, the total possible number of ways for selecting 5 people from 11 people will be: 
Now if both the husband and wife are hired, then it means <u>the remaining (5-2)= 3 positions are filled from the remaining (11 -2) = 9 people</u>.
So, the possible number of ways for selecting 3 people from 9 people will be: 
Thus, the probability 
Answer:
False the correct answer would be x^12
Step-by-step explanation:
When calculating an exponent at the power of an exponent the exponent should be multiplied. 3x4=12. The correct answer is x^12.
