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:
12.50
Step-by-step explanation:
18.20-5.60= 12.50
Multipy 3 by 6 multiply 1 by 4 and 7 by 4 then add the numbers
There are several important information's already given in the question. Based on those given information's the answer can be easily deduced.
Ratio of the radii of two spheres = 9 : 2
then
Ratio of the volume of the two spheres = 9^3 : 2^3
= 729 : 8
I hope that this is the answer that you were looking for and the answer has actually come to your desired help.
Because the shape is not undergoing a dilation, the perimeter of the original image and the new image is the same. The only thing that is changing is the placement of the original figure.
I hope this helps! :)
