Answer:
3610 dollars
Step-by-step explanation:
Remark
If you take the Cube Root of the volume, that will give you the length of an edge of the cube. If you square the edge, you get the area of one of the faces of the cube.
The Cost = the Area of 1 face * 10 dollars. is the answer.
Given
Volume = 6859 cubic feet
Cost per square foot = 10 dollars.
Solution
V = 6859 feet^3 Take the cube root of both sides
Edge = ∛V
Edge = ∛V = ∛6859
Edge = 19 feet exactly.
Area of the floor = s^2
Area of the floor = 19^2
Area of the floor = 361 square feet
Cost = 10 * 361 = $3610
<u>The correct answer is </u><u>8.5 in.</u>
<h3 /><h3>What is Heron's formula in math?</h3>
- Heron's formula, formula credited to Heron of Alexandria for finding the area of a triangle in terms of the lengths of its sides.
- In symbols, if a, b, and c are the lengths of the sides: Area = Square root of√s(s - a)(s - b)(s - c) where s is half the perimeter, or (a + b + c)/2.
we know that
The formula of area of triangle is equal to
We have
b = BC = 6 in
h = AD = x in
substitute
Heron's Formula is a method for calculating the area of a triangle when you know the lengths of all three sides.
Let a,b,c be the lengths of the sides of a triangle.
The area is given by:-
where p is half the perimeter
a = 9 in , b= 9 in, c = 6 in
Find the area
Substitute the value of the area in the equation 1 and solve for x
25.46 = 3x
x = 25.46/3
x = 8.5 in

Answer would be : B-p > 2
Answer:
D. b + a = c
Step-by-step explanation:
c – a = b
Add a to both sides.
c = b + a
b + a = c
Answer: D. b + a = c
