Answer:
The volume of the given figure is 150 mm³
Step-by-step explanation:
The formula of the volume of the triangular pyramid is V = 
AH, where
- A is the area of its base
The formula of the area of a triangle is A = 
bh, where
- b is the length of its base
- h is the length of its height
In the given figure
∵ The pyramid has a triangular base
∵ The triangle has a base of 12 mm and a height of 7.5 mm
∴ b = 12 mm and h = 7.5 mm
→ By using the 2nd formula above, find the area of the base
∴ A = (12)(7.5)
∴ A = 45 mm²
∵ The height of the pyramid is 10 mm
∴ H = 10 mm
∵ A = 45 mm²
→ Substitute them in the first formula above to find the volume
∴ V = (45)(10)
∴ V = 150 mm³
∴ The volume of the given figure is 150 mm³
Answer:
0.6b - 3c
Step-by-step explanation:
Multiply 0.2 and 3b
0.2 x 3b = 0.6b
Then multiply 0.2 and 15c
0.2 x 15c = 3c
We can't add these, 3c and 6b because they have different letters.
different letter vs. different letter =
don't add
different letter vs. normal number like 5 =
dont add
same letter vs. same letter =
add
normal number vs. normal number =
add
This all goes the same for dividing, subtracting, and multiplying
I hope this helped! :)

a 'quadrilateral' is a 4-sided polygon and all 4-sides polygons have interior angles whose sum is 360 degrees
Answer:
Step-by-step explanation:
1) Number of children = c
Number of adults = a
Total ticket = 250
c + a = 250 -------------------(I)
Cost of 'c' children tickets = 200c
Cost of 'a' adult tickets = 450a
Total cost = 76000
200c + 450a = 76000 ------------------(II)
Multiply (I) by (-200) and then add
(I)*(-200) -200c - 200a = -50000
(II) <u> 200c + 450a = 76000 </u>
<u> </u> 250a = 26000
a = 26000/250
a = 104
Plug in a = 104 in equation (1)
c + 104 = 250
c = 250 - 104
c = 146
2)Number of children = 146
Number of adults = 104
