1. 22 students is 40% of 55

2. 24 red marbles is 40% of  60 marbles

3. 15% of $9 is $1.35

4. 12 is 6% of 200

5. Bethany sent 9 text messages to her friend yesterday.

6. There where 17.01 people in the survey.

7. The sales tax rate is 6.5%.

8. There were 10(0.1) from 18-29 that voted in the election.

9. There were 35(0.35) from 50-64 that voted in the election.

10. There were 25(0.25) of over 64 year old's that voted in the election.

11. Sahli  is incorrect because there is 30 people within ages 30-49. I think he came up with that answer so quickly because 30 + 49 = 1470 and divided by 14 = 105 with this you add 30 and get 135.

Todd is 81 years younger than Rosa. 3 years ago, Rosa’s age was 4 times Todd’s age. How old is Todd now?
Delvig [45]
Let t represent Todd's age now.
.. 4(t -3) -(t -3) = 81 . . . . . . 3 years ago, their differnce in ages was 81.
.. 3t -9 = 81
.. t = (81 +9)/3 = 30

Todd is 30 now.

_____
You can also work this by considering "ratio units." 3 years ago, the ratio of their ages was 4:1, a difference of 3. That difference corresponds to 81 years, so each "ratio unit" represents 81/3 = 27 years. Todd's age then was 1 ratio unit, 27 years. Now, Todd's age is 30.

Romashka [77]

Answer:

11,880 different ways.

Step-by-step explanation:

We have been given that from a pool of 12 candidates, the offices of president, vice-president, secretary, and treasurer will be filled. We are asked to find the number of ways in which the offices can be filled.

We will use permutations for solve our given problem.

^nP_r=\frac{n!}{(n-r)!}, where,

n = Number of total items,  

r = Items being chosen at a time.        

For our given scenario n=12 and r=4.

^{12}P_4=\frac{12!}{(12-4)!}

^{12}P_4=\frac{12!}{8!}

^{12}P_4=\frac{12*11*10*9*8!}{8!}

^{12}P_4=12*11*10*9

^{12}P_4=11,880

Therefore, offices can be filled in 11,880 different ways.
