Answer:C
Step-by-step explanation:9 times 12 equals 108
Are you have to do for the answer is just multiply those two numbers and then figure out if one of those multiple-choice questions have the same answers than that’s answer
Answer:
See below.
Step-by-step explanation:
To calculate a percentage divide by the part by the whole, You will get a decimal. The decimal becomes a percentage after you multiply by 100. This moves the decimal place two places to the right. So 0.10 becomes 10%.
1. 20 is 50% of 40 since 20/40 = 0.5
2. 8/ 32 = 0.25 so it is 25%
3. 2/40 = 1/20 = 0.05 so it is 5%
4. 100/25 = 4 so it is 400%
5. 3/ 2 = 1.5 so 150%
To find a percentage of a number, multiply the number by the decimal conversion of the percent.
6. 0.15(300) = 45
7. 33/75 = 0.44 so it is 44%
8. 12/18 = 2/3 = 0.66 so it is 66%
9. 0.35(1000) = 350
10. 40 is 20% of what can be solved by remembering that 20* 5 = 100%. So 5*40 = 200. The number is 200.
Answer:
Number of committees that are possible =210
Step-by-step explanation:
Total names in ballot = 10
Total members to be elected for the committee = 4
So, we need the number of different ways in which 4 names out of 10 can be elected for the committee.
To find the number of ways in which the committee can be elected, we use the combinations which is given as
where represents total number of members and represents total number of members to be elected.
So,
[Canceling the common numbers]
∴ Number of committees that are possible =210
