Answer:
22.5
Step-by-step explanation:
What you need to do is calculate the volume of the Box. With the box being the volume of the piramid added to the prism surrounding the box with volume 15.
If you want to calculate it yourself stop reading here, because I will work it out now.
Volume box = a*b*c
Volume prism = 15
Volume pyramid = (b * c * a)/3
The prism has the volume of the box minus the pyramid so
abc - (abc)/3 = 15
abc - (1/3)abc = 15
(2/3)abc = 15
abc = 22.5
So 22.5 is the volume of the figure
Answer:
D=6+13=19
Step-by-step explanation:
F=26+12=38
M=109-18=91
k=231-56=175
Answer: Angle BEC is also 45 degrees.
Step-by-step explanation: This is because the opposite and congruent angle of BEC is 45 degrees. Congruent means the same. Therefore, Angle BEC is 45 degrees.
The first one because when you simplify it equals to 3<span>√2x2x2x2x2x2xk12, so then you can take out two 2s and 4ks.

C = child tickets
a= adult tickets
c + a = 157
6.20c + 9.30a = 1178.00
6.20c + 9.30a = 1178.00
-6.20c -6.20a = -973.40
3.10a = 204.60
a = 66 adult tickets
c + 66 = 157
-66. -66
c= 91 child tickets
