Answer:
14.95
Step-by-step explanation:
74.75 divided by 5 is 14.95
B = 1/4c + 14
d = 5/4c - 2
b = d
1/4c + 14 = 5/4c - 2
1/4c - 5/4c = -2 - 14
-c = - 16
c = 16 <=== chris got 16 correct
b = 1/4c + 14
b = 1/4(16) + 14
b = 4 + 14
b = 18 <=== Brian got 18 correct
d = 5/4c - 2
d = 5/4(16) - 2
d = 20 - 2
d = 18 <=== damien got 18 right also
Answer:
he sum of the angles in all these triangles will be n x 180 degrees. The sum of the angles around the interior point is clearly 360 degrees, so the sum of the polygon’s angles will be (180n)-360 = (n-2) x 180 degrees.Here we have (n-2) x 180 = 2160, so n-2 = 12. So the polygon has 14 sides. 606 views

Answer:
Step-by-step explanation:
The formula for the volume of a sphere of radius r is V = (4/3)(pi)r^3.
Here, with r = 3 in, the volume is
V = (4/3)(3.14)(3 in)^2, or V = 36(pi)(27 in)^3 = 36pi in^3
Answer:
Step-by-step explanation:
We are given the following in the question:
A storage shed is to be built in the shape of a (closed) box with a square base.
Volume = 150 cubic feet
Let s be the edge of square base and h be the height.
Volume of cuboid =
where l is the length, b is the base and h is the height.
Volume of box =
Area of base =
Cost of concrete for the base = $4
Cost of base($) =
Area of roof =
Cost of material for the roof = $2
Cost of roof ($) =
Area of 4 walls =
Cost of material for the side = $2.50
Cost of material of side($) =
Total cost
= Cost of base + Cost of 4 sides + Cost of roof
is the required cost function.
