Answer:
3 inches
Step-by-step explanation:
Given that the volume of the rectangular prism or a cylinder needs to be cubic inches. The container being made is a rectangular prism with a height of inches and length of inches.
A rectangular prism is a polyhedron with six rectangular faces.
Therefore the required width (w) needed to produce a container with a volume of cubic inches is given by:
volume of a rectangular prism = height * width * length
Substituting:
= * * w
258.75 = 11.5 * 7.5 * w
w = 258.75 / (11.5 * 7.5)
w = 3 inches
The required width is 3 inches
Answer:
y=1
Step-by-step explanation:
Start by plugging in -3 for x in the equation 2x+5y=-1 then solve for y.
2(-3)+5y=-1
-6+5y=-1 (add 6 to both sides)
5y=5 (divide both sides by 5)
y=1
X=14
every triangle equals 180 when adding all the angles together 72+36 = 108 So 180-108 = 72 (also note this is an isosceles triangle)
Now 72-16 = 56
56÷4 = 14
