The correct answer is C. Aimee used the Associative and Commutative properties to put numbers that are easy to add next to each other.
Answer:
40 percent increase
Step-by-step explanation:
Starting point - 95
End point - 133
133-95 = 38
38/95 = 0.4
0.4*100=
40
Answer:
24/5
Step-by-step explanation:
The way I think about areas of sectors is a fraction of the pie. You know what percentage of the "pie" (in this case, circle) you want, because they give you the angle of the sector and you know a circle always has 360°. So technically, you're trying to find 48/360 th of the entire area (36). If you're using a calculator, it doesn't matter if you simplify the fraction, but if you're doing it by hand simplifying makes everything a lot easier.
The equation will be:
Area = 24/180 × 36
= 2/15 × 36
= 72/15
= 24/5
I hope this helped! Also, in Khan Academy, when you get an answer wrong/right, you can view their explanation by clicking "hint" or sometimes "see how we did it" shows up.
Yes, a trinomial is also a polynomial.
We want to choose 4 people and we have 6 people to choose from. This is a combination of 6, 4 by 4. Also called <em>six choose four</em>.
The following formula:
Is the combination of objects choosen from a total of . It's choose .
For our problem, we just need to compute the following:
Thus
Therefore the answer is 15 different combinations
