12
Step-by-step explanation:
Quotient rule,
Do this,
a^(n-3)=a^9
Since the exponents have to be the same, this turned into a simple one step equation:
n-3=9
+3 +3
**n = 12, so the final answer is 12.
Answer:
27.37 and 9.18
Step-by-step explanation:
(4)
Using the cosine ratio in the right triangle
cos64° = =
( multiply both sides by x )
x × cos64° = 12 ( divide both sides by cos64° )
x = ≈ 27.37 ( to the nearest hundredth )
(5)
Using the sine ratio in the right triangle
sin35° = =
( multiply both sides by 16 )
16 × sin35° = x , then
x ≈ 9.18 ( to the nearest hundredth )
Answer:
Jim pays 200 more dollars per month than Mike.
Step-by-step explanation:
Jim--> $1600/month
Mike--> 7/8(Jim's rent)
7/8(Jim's rent)
7/8(1600)
= $1400
1600-1400= 200
Jim pays 200 more dollars per month than Mike.
I hope that makes sense!
