Answer:
13.01 d -2.65
Step-by-step explanation:
3.26d + 9.75d - 2.65
Combine like terms
3.26d + 9.75d - 2.65
13.01 d -2.65
Answer:
(5, -3)
Step-by-step explanation:
let (x1, y1) = (6, -7) and (x2, y2) = (4,1)
(Xmidpoint, Ymidpoint) = ( (x1+x2) / 2, (y1+y2) / 2)
= (5, -3)
Answer:
20.78 cm^3 to the nearest hundredth.
Step-by-step explanation:
Volume = 1/3 * a * h where a = area of triangular base and h = the height.
The area of the triangle
= 1/2 * base * height
Its height = √(10^2-5^2)
= √75.
So its area = 1/2 * 10 * √75
= 5√75
So for the pyramid we have:
300 = 1/3 * 5√75 * h
h = 300 / (1/3 * 5√75)
= 20.78 cm^3.
7n+12
if n is the number of students, then n=6 so plug 6 in for n
so 7(6)+12
7(6)=30+12=42
so the cost for 6 students would be $42
