Answer:
1. 3sqrt(2)
Choice C
2. 2sqrt(3)
Choice D
Step-by-step explanation:
1. sqrt(x+3)
sqrt(15+3)
sqrt(18)
sqrt(9*2)
sqrt(9)sqrt(2)
3sqrt(2)
Choice C
2. 6/sqrt(x)
6/sqrt(3)
no radicals in the denominator, multiply by 1 in the form of the radical
6/sqrt(3) * sqrt(3)/sqrt(3)
6sqrt(3)/ (sqrt(3)*sqrt(3))
6sqrt(3)/3
2sqrt(3)
Choice D
Answer:
B. 20
Step-by-step explanation:
First, 20% of 20 is 4.
36 decreased by 4 (36-4) is 32.
The equation is N (160%)=32 or 1.6n=32
160% because it was already 100%, and its increased by 60% (100+60)
Divide both sides by 1.6.
You get n=20

Answer:
1 1/4
Step-by-step explanation:
You know that 8/8 = 1.
Removing a common factor of 2 from numerator and denominator of 2/8 reduces the fraction to lowest terms: 1/4
Your mixed number is 1 1/4.
If you're at a 75% in the class and get a 75% on the midterm, you will still have a 75% no matter how many points it's worth.
