Answer:
The height is 5ft
Step-by-step explanation:
We know the area is 30ft^2 and the base is 12 ft.
Plug that information in the formula for the area of a triangle,
Formula for area of a triangle:
A = (1/2)bh (area is one half of the product of the base and height)
The question gives us A = 30, and b = 12. We can plug them in and find h
30 = (1/2)(12)h
Now solve for h
30 = 6h (1/2)(12) means '12 times one half' or 'half of 12' which is 6
5 = h (30 divided by 6 is equal to 5)
Answer:
the organizers ordered 3200 tickets
Step-by-step explanation:
Answer:
230.55/8.70 = 26.5 hours (round as appropriate)
This ratio can be written as 8x+5x =390
Add the variables
13x = 390
Divide by 13 to get the value of x
390/13 = 30
