Answer:
AC is about 41. 095 miles long.
Step-by-step explanation:
You can use the Law of Cosines to solve this: c^2 = a^2 + b^2 – 2ab cos(C)
Substitute in your values, and you're good to go!
c^2=16^2+28^2-2(16)(28)(cos(117))
c^2 = 256 + 784 - 896(cos(117))
c = sqrt(1040 - 896(cos(117)))
c is about 41. 095 miles long.
Answer:
38 grams

7.6*5=38
Answer:
The first answer choice: 15 cm x 3.14 cm x 2cm^2 = 188.4 cm^3
Step-by-step explanation:
Formula:
V=πr^2h
radius=2
height=15
V=π(2)^2*15
π(4)*15
4*15=60
60π
π=3.14
60(3.14)
188.4
Since its volume you have to cube it
188.4 cm^3
Answer: 1800
Step-by-step explanation:
Given : A certain system has two components.
Number of different models of the first component = 6
Number of different models of the second component = 10
A salesman must select 2 of the first component and 3 of the second to take on a sales call , so we use combinations ( ∵ order of selection not matters)
The number of different sets of components can the salesman take = 
![\dfrac{6!}{2!(6-2)!}\times\dfrac{10!}{3!(10-3)!}\ \ [\because\ ^nC_r=\dfrac{n!}{r!(n-r)!}]](https://tex.z-dn.net/?f=%5Cdfrac%7B6%21%7D%7B2%21%286-2%29%21%7D%5Ctimes%5Cdfrac%7B10%21%7D%7B3%21%2810-3%29%21%7D%5C%20%5C%20%5B%5Cbecause%5C%20%5EnC_r%3D%5Cdfrac%7Bn%21%7D%7Br%21%28n-r%29%21%7D%5D)
Hence, the number of different sets of components can the salesman take = 1800
