Hello from MrBillDoesMath!
Answer: Choice "B", which is 3
Discussion:
The consecutive integers <= 7 are
1,2,3,4,5,6,7
4 is the largest number in this list that makes sense in this problem (for example, 5 + 6 > 7, 7 + 6 > 7 don't satisfy the problem)
1 + 2 = 3 <= 7
2 + 3 = 5 <= 7
3 +4 = 7 <=7 (*)
The lesser integer in the last equation (*) is 3
Thank you,
MrB
If you use the formula V=bh you can find the volume of a tranangular prism.
To find the area of the triangle you have to use the formula A=1/2bh
A=1/2(14)(20)=140ft2= Base of the triangle
V=bh V=140x30
V=4200ft2
you do 15.0 x 4.0 and that would give you the answer of 60.
the bridge is 60m above the water.
