Answer: 1,162.9 cm3
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Volume of a square pyramid: 1/3 x base area x height
Where
base area = base side length ^2
Replacing with the value given:
Base area = 15.9^2
base area : 252.81 cm2
Back with the volume formula:
V = 1/3 x base area x height
Replacing with the values given and solving for V (volume)
V = 1/3 x 252.81 x 13.8 = 1,162.9 cubic centimeters
Feel free to ask for more if needed or if you did not understand something.
The answer would be 2:3.
So basically two - thirds.
Hope this helps and if it does happy studying.
Answer:
The slope remains a constant 
as it is parallel.
Explanation:
1. Line Q is defined as a slope of 
; i.e. 
2. Line R is defined to be parallel of Line Q.
3. Line Q is linear and has no domain restrictions.
The definition of being parallel requires the same slope.
The sum of the left side of these two equations is equal to the same of the right side is these two equations
4x+8y + (-4x+2y) = 20 + 30
10y =50 ( x is eliminated)
y=5
Take this into the second equation
-4x +2y = 30
-4x + 2*5 = 30
x=-5
So x=-5
y=5
Answer:
3
Step-by-step explanation:
(40/5)-7+2
PEMDAS says parentheses first, so divide inside the parentheses
(8)-7+2
Then add and subtract from left to right
1 +2
3
