Answer:
Step-by-step explanation:
Given that,
The perimeter of the base of pyramid, P = 10.7 ft
The height of the pyramid, h = 9.8 ft
We need to find the volume of the pyramid.
The perimeter of square is given by :
4s = 10.7, s is side
s = 2.675 ft
Now the volume of pyramid is given by :
So, the volume of the pyramid is equal to .
Answer:
see below
m = males = 50
e = females = 25
a = adults = 7
Step-by-step explanation:
Givens
Let the adults = a
let the males students = m
lef the female students = e
Equations
a + m + e = 82
m = 7*a + 1
e = 1/2 * (7a + 1)
Solution
a + 7a + 1 + 1/2(7a + 1) = 82 Remove the brackets on the left.
a + 7a + 1 + 3.5*a + 1/2 = 82 Combine the like terms on the left.
11.5a + 1.5 = 82 Subtract 1.5 from both sides.
11.5a + 1.5 - 1.5 = 82 - 1.5 Combine
11.5a = 80.5 Divide by 11.5
a = 80.5/11.5
a = 7
The number of adults = 7
===============================
m = 7a + 1
m = 7*7 + 1
m = 50
===============================
e = 1/2 m
e = 1/2 * 50
e = 25
Answer:
- 4.5x + 4.7
Step-by-step explanation:
(2.5x - 5) - (7x - 9.7)
2.5x - 5 - 7x + 9.7
2.5x - 7x + 4.7
- 4.5x + 4.7
D (5, -5)
E (2, -7)
F (6, -1)
G (10, -8)
If you need an explanation as to how I did, you just add 4 to the x coordinate and subtract 5 from the y coordinate since going down is negative.
