Answer:
I'm pretty sure its B
Step-by-step explanation:
I think it's that because you are trying to divide 3/4 by 1/10 so you need to flip the second number and multiply 3/4 by 10/1.. not positive haven't done it in a while.
Your answer should be 32 because 384 <span>÷ 12 = 32</span>
Answer:
24 possible outcomes
Step-by-step explanation:
Combination has to do with selection. For example, if r object is selected from a pool of n objects, the number if possible ways can be expressed according to the combination formula:
nCr = n!/(n-r)!r!
Applying this in question, if each student receives one of 4 calculator models and one of 3 types of ruler, the number of ways this can be done is:
4C1 × 3C1
4C1 = 4!/(4-1)!1! {If a student gets one calculator)
4C1 = 4×3×2/3×2
4C1 = 4ways
3C1 = 3!/(3-2)!1! {If a student gets a ruler}
3C1 = 3×2/1
3C1 = 6ways
Total number of possible outcomes if a student gets one ruler and one calculator will be 4×6 = 24ways
The formula for the area is length times width, so for question 17, multiply those two numbers together.
If he drives 9 miles to work per day and works 5 days a week, you would need to get the total of miles per week. Then, once you do, multiply that number by 52.
