Answer:
128 students in total
Step-by-step explanation:
25/100 = 1/4
1/4 = 32/ x
1 x 32
6 sin 2x = 6 cos x Using the identity sin 2x = 2 sin x cos x:-
12 sin x cos x = 6 cos x
6 cos x ( 2 sin x - 1) = 0
either 6 cos x = 0 or 2 sin x - 1 = 0 so sin x = 1/2
x = pi/2, 3pi/2 , pi/6, 5pi / 6
answer is ( pi/6, pi/2, 5pi/6, 2pi/2)

Answer:
The surface area of the prism is <u>480 in²</u>.
Step-by-step explanation:
Given:
The prism dimensions are 8in 15in 17in and 9in.
Now, to find the surface area:
So, to get the surface area we put formula:
a=8in, b=15in, c=17in and h=9in.
Surface area = 2A+(a+b+c)h.
Whereas,
And,
<em>Now, we find </em><u><em>s</em></u><em> first:</em>
<em>Then, we get</em><u><em> A </em></u><em>:</em>
<em>On solving we get:</em>
Now, putting the value of A in the formula to get the surface area:
Therefore, the surface area of the prism is 480 in².
The answer is going to be b. hope that helped
