Answer:
and
Step-by-step explanation:
Given:
Equation 1:
Simplifying the above equation by dividing both sides by 100
Equation 2:
Simplifying the above equation by dividing both sides by 400.
Now the system of equation is:
(1a)
(2a)
Solving by elimination
Multiplying equation (2a) with
(2b)
Adding equations (1a) and (2b) in order to eliminate
+
We get
∴
Plugging in equation (2a).
Adding both sides.
∴
Answer:
5 is b and 6 is b
Step-by-step explanation:
5. The area of the trapezoid face is 80 and then multiply by 9 to get volume.
6. The area of the trapezoid face is 16.5 and then multiply by 13 to get volume.
Make sure you pick b for 6 and NOT d. The units are not correct for volume in d.
Answer:
120 %.
Step-by-step explanation:
That is (1032 * 100) / 860 %
= 120 %
Answer:
l = 626.4/bh
Step-by-step explanation:
A triangular prism have a base that is triangular in shape. The volume of a prism has the volume represented as follows.
volume = Al
where
A = Base area
l = width
Since the base is a triangle the base area will be the area of a triangle. Therefore,
volume of a triangular prism = 1/2bh l
where
b = base of triangle
h = height of triangle
volume = 313.2 ft³
313.2 = 1/2bh l
Make the width(l) subject of the formula
multiply both sides by 2
626.4 = bhl
divide both sides by bh
l = 626.4/bh
l = 626.4/bh
recall l = width
