Answer:
Option C - 16 units
Step-by-step explanation:
Since the base is a square and it has an area of 576 sq.units, thus, if the side length of the base is x, then;
x² = 576
x = √576
x = 24
To get the height, we will divide this side length by 2 and use Pythagoreas Theorem.
Since, we are told that the pyramid has a slant height of 20 units,
So using pythagoras theorem, we can find the height of the pyramid as;
h² = 20² - (24/2)²
h² = 400 - 144
h² = 256
h = √256
h = 16 units
Answer:
The area is 207 square feet
Step-by-step explanation:
*The area of the rectangle whose dimensions are 21 and 15 is 315 square feet
*The area of the rectangle whose dimensions are 12 and 9 is 108 square feet
*By subtracting the small area from the big area you will get the area of the polygon
*The area of the polygon = 315 - 108 = 207 square feet
Answer: x = 9.5
Step-by-step explanation:
3x - 12 = 5x - 31
First, add 31 to each side.
We get:
3x + 19 = 5x
Subtract 3x from each side.
We get:
19 = 2x
Divide both side by 2
9.5 = x
17/4 because you have to do 4x4 +1 which equal 17 then make that an improper fraction.
The answer is A. 1/5 because only 1 out of the 5 possible answers has 1 pair of parallel sides.
A. 1/5
