Answer:
(c)
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos42° =
= 
Multiply both sides by 12
12 × cos42° = x, hence
x ≈ 8.9 → (c)
Since you said men to women, there are 5 men in the dance recital and 6 women in the dance recital.
1. Look how the problem states. Ex: Ratio of men to women.
2. Look at the ratio. 5:48.
3. We know that there are 48 female performers at the dance recital.
So, there are 5 men at the dance recital.
Answer:$25.80
Step-by-step explanation:
6.45/5 = 1.29
1.29 x 20 =25.80
Lateral area of triangular prism = (a+b+c)h where a, b and c are the sides of the triangular base, h is the height.
LA= (a+b+c)h=
a=4
b=6
c=?
c=9
h=8
c=√6²+4²=√80 or approximately 9
you should get An Area= (4+6+√80)8
LA= 80+8√80
Answer:
7/12 cannot be reduced
Step-by-step explanation:
7 = 7
12 = 2 * 2 * 3
7 and 12 have no common factors other than 1, so the fraction 7/12 cannot be reduced. 7/12 is already written in lowest terms.
