Hi there!
We know that the equation for the volume of a pyramid is:
V = 1/3(bh)
We know that:
V = 200 km³
b = 12 × 5 = 60 km²
We can plug these into the equation:
200 = 1/3(60)(h)
Simplify:
200 = 20h
Divide both sides by 20:
200/20 = 20h/20
h = 10 km
Since 6 is positive, it's (x+blank)^2
6/2=3, and (x+3)^2 = x^2+6x+9. We have x^2+6x-2, so we have to add 9 to both sides to get (x+3)^2-2=9, then subtract 9 from both sides to get
(x+3)^2-11=0, or (x+3)^2=11. Square root both sides to get x+3=sqrt(11), and x=sqrt(11)-3, which is approximately 0.32
Answer:
x=19, y=-5
Step-by-step explanation:
Add the equations in order to solve for the first variable. Plug this value into the other equations in order to solve for the remaining variables.
Point Form:
(19, -5)
Equation Form:
x=19, y=-5
Hope this helps.
Answer:
m = 30
Step-by-step explanation:
total = 24
m = amount paid
change = 6
m - 6 = 24
<u> +6 +6</u>
m = 30

Answer:
1. 45
2. 24
3. 32
Step-by-step explanation:
One
Ashley= 3/4 * Steve
Ashley= 3/4 * 60
Ashley = 180/4
Ashley = 45
Two
60% of 40
60/100 * 40
2400/100 = 24
Three
40% 80 = 40/100 * 80 = 3200 / 100 = 32
