The surface area of a rectangular prism is 2,280 square feet. If the width and height are 20 and 15 feet, the length of the pris
kolbaska11 [484]

Answer:

The statement is trrue.

Step-by-step explanation:

Given that,

The surface area of a rectangular prism = 2,280 square feet

Width, b =20 feet

Height, h = 15 feet

The formula for the surface area of a rectangular prism is given by :

A=2(lb+bh+hl)

Where

l is the length of the prism

Substitute all the values,

A=2(lb+bh+hl)\\\\2,280=2(20l+20\times 15+15l)\\\\1140=(20l+20\times 15+15l)\\\\1140=35l+300\\\\1140-300=35l\\\\35l=840\\\\l=24\ feet

So, the length of the prism is equal to 24 feet.

Find the values of x and y that make k || j and
MArishka [77]

Answer:

  • x = 80°
  • y = 130°

Step-by-step explanation:

The interior is a parallelogram when adjacent angles are supplementary. This requires ...

  (x -30)° + (x +50)° = 180°

  2x + 20 = 180 . . . . . . . . . . . collect terms, divide by °

  2x = 160 . . . . . . . . . . . . . . . subtract 20

  x = 80 . . . . . . . . . . . . . . . . . divide by 2

Then the angle x+50 is ...

  (x +50)° = (80 +50)° = 130°

This is also the measure of the angle marked y.

For the lines to be parallel, x = 80, y = 130°.

Two trains leave stations 442 miles apart at the same time and travel toward each other. One train travels at 95 miles per hour
Brrunno [24]

(75 + 95) \times x = 442

x =  \frac{442}{75 + 95}  = 2.6

so it takes 2.6 of hours which is the same as 2 hours and 36 minutes for them to reach eachother.
