Step-by-step explanation:
Let the number of singing act be x
Let the number of comedy act be y
If the total act is 14, then;
x+y = 14..... 1
If singing acts are 4.5 minutes long and comedy acts are 3.5 minutes long and the acts lasts 59 minutes, then:
4.5x + 3.5y = 59 .......... 2
Solve both equation simultaneously for x and y
x+y = 14
45x+35y = 590
.................................
x+y = 14......... *9
9x+7y = 118....... 1
...............................
9x+9y = 126
9x+7y = 118
Subtract both equations
9y-7y = 126-118
2y = 8
y = 8/2
y = 4
Substitute y = 4 into equation 1;
From 1: x+y = 14
x+4 = 14
x = 14-4
x =10
Hence there are 10 singing acts and 4 comedy acts in the show
Answer: I assume the radius is 1/2 the base of 6 in.
r = 3 ft
h = 10 ft
s = 10.4403 ft
V = 94.2478 ft³
L = 98.3976 ft²
B = 28.2743 ft²
A = 126.672 ft²
r = radius
h = height
s = slant height
V = volume
L = lateral surface area
<span>B = base surface area </span>
A = total surface area
π<span> = pi = 3.14159</span>
<span>√ = square root</span>
I really do not know the answer to this question
Hi!



<u>Explanation: </u><u><em>This question is about math, and this lesson is about order of operations. I will give you a hint. You had to used PEMDAS, P-Parenthesis should be go first, E-Exponents, M-Multiply, D-Divide, A-Add, and S-Subtract. If you use multiply, divide, add, or subtract it should go left to right. First, you had to multiply and divide should go left to right. And it gave us -15+10. And finally, you should add and subtract by left to right. And it gave us -5 is correct answer. Hope this helps! Thank you for posting your question at here on Brainly. And have a great day. -Charlie</em></u>
