777 ÷ 46 = 16 Remainder 41
16 buses and the rest have to fit into vans
41 ÷ 12 = 3 vans remainder 5
we need 4 vans, so the number of empty seats = 12 - 5 = 7
Ans: 16 buses, 7 empty seats in the last van.
15% of 400 = x
.15 x 400 = x
X = 60 (tip)
400 + 60 = 460
Answer:
1. 42000/70000= 6/10= 3/5
2. 11/15 were not medium moutain stages
3. 3/5 = .60
Letter E is correct.
Area of equilateral trianlge= (1/2) tiime a^2 square root 3
Equation for the base is = x^2+y^2 =9
at x ,
y= square root (9-x^2)
Side of triangle a= 2y
d times Volume = (1/2)a^2 square root 3 dx
d times V= (square root 3) (9-x^2) dx
V= square root 3 INT (9-x^2) dx
-3V= 2square root INT (9-x^2) dx
0
V= 2 square root 3 ( 9x-x^3/3)
V=2 square root 3 ( 27-9)
V= 36 square root 3
The answer is E.
You would distribute multiply every thing inside the parenthesis by the number on the out side of it on the the left the go to the other side of the addition sign and do the same then combine like terms
