A shipping container is in the shape of a right rectangular prism with a length of 13
Lilit [14]

Answer:

371 pounds

Step-by-step explanation:

First you find how much space is in the container

length is 13

width is 15

height is 10

2 * (15 * 13 + 10 * 13 + 10 * 15)= 950

The total space in the container is 950

Then multiply it by 0.39 to find the weight

950 * 0.39 = 370.5

Round to the nearest pound

.5 rounded is rounded to a whole number

371 pounds

Which matrix can be used to solve the system?
Brut [27]
It's the last choice.  In the top row you have the 1's that are the coefficients on the x and the y, and the solution for that equation is 21; in the second row you have the 5 from the x and the 4 from the y and the solution for that equation which is 20.  I'm more used to writing them down instead of across, but there you have it anyways
