This rectangular prism is intersected by a plane that contains points n, p, u, and r.
what is the perimeter of the cross section?
enter your answer in the box. round only your final answer to the nearest tenth.

The perimeter is : 44.3 ft

Step-by-step explanation:

Two of the parallel sides ST and NP of the plane will each equal = 6  feet

Side PU will be

= 261 feet

=16.155 feet

So, the perimeter will be = 44.31 feet

Rounding this final answer to the nearest tenth we get 44.3 feet.

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
