The answer is $380.
First find the area of the triangle. The area (A) of the triangle with base b and height h is:
A = b * h / 2
The width of the floor is the base of the triangle: b = 8 ft
The extension into the area is the height of the triangle: h = 10 ft
A = 8 * 10 / 2
A = 80/2
A = 40 ft²
The cost is $9.50/ft². So, the price of the white marble section is:
40 ft² * $9.50/ft² = $380
Answer: in order, the answer is 3, height of the pyramid, 6, then 108

Answer:
27
Step-by-step explanation:
-7*-3/5 * 45/7
-7/1 * -3/5 =21/5 * 45/7 = 3/1 *9/1=27
Answer:
True
Step-by-step explanation:
we know that
The opposite sides of a parallelogram are parallel and the length of their sides is equal.
step 1
<em>Find the slope of each side</em>
we know that
If two lines are parallel then their slopes are the same
The formula to calculate the slope between two points is equal to
we have
<em>one side</em>
Substitute the values
<em>opposite side</em>
Substitute the values
compare
m1=m2
therefore
both lines are parallel
step 2
Find the distance
the formula to calculate the distance between two points is equal to
we have
<em>one side</em>
Substitute the values
<em>opposite side</em>
Substitute the values
Compare
d1=d2
Both sides have the same length
so
1) Both lines are parallel
2) Both sides have the same length
therefore
The statement is True
