Answer:
16.8 cm
Step-by-step explanation:
Sin (theta)=opposite/HYPOTENUSE
Where theta=71 and opposite=15.9
Putting in the above formula
Sin 71=15.9/AC
AC=15.9/sin71
AC=15.9/0.945
AC=16.8 cm
21×pi
Step-by-step explanation:
Volume of Cone = 1/3×pi×r^2×h
1/3 × pi × (3)^2 × 7
=65.97 in^3 and in terms of pi, 21pi
Use p.e.m.d.a.s.
<span>first multiply 6Q and 8Q = 48Q
then subtract 58Q and 48Q = 10Q

Answer:
1. -7.5
2. $1
3. 40
Step-by-step explanation:
For number 1, it can be solved by using the PEMDAS method, or see explanation below:
6x - 4x - 36 = 6 - 2x
2x - 36= -2x + 6
4x + 36 = 6
4x = -30
x = -15/2 or -7.5
For number 2, substitute 3 into both equations:
f(x) =1.50(3) + 2.00
and
f(x) = 2.00(3) + 1.50
This would get $6.50 and $7.50, which, if subtracted, gets $1.
For number 3, do something similar to the previous problem. Substitute 3 for x. It would be 5(2^3), or 40.
Hope this helps!
