A shipping container is in the shape of a right rectangular prism with a length of 7.5
katrin [286]

Answer:

about 1036 pounds

Step-by-step explanation:

First we'll find the volume, then we'll use that to get the weight.

V = lwh

  = 7.5 * 14 * 10.5

  = 1102.5 cubic feet

We know that it weighs .94 pounds per cubic foot. The per tells us to multiply.

1102.5 cubic feet * .94 pound / cubic foot

          = 1036.35 pounds

          <u>= about 1036 pounds</u>

densk [106]

Answer:  There are 177100 possible groups.

Step-by-step explanation:

Given: Total employees = 25

Number of  employees  wants to choose = 6

The combination of n things taken r at a time is given by:-

^nC_r=\frac{n!}{r!(n-r)!}

Put n = 25 and r= 6, we get

^{25}C_6=\frac{25!}{6!(25-6)!}\\\\=\frac{25\times24\times23\times22\times21\times20\times19!}{6!19!}\\\\=177100

Hence, there are 177100 possible groups.

Need help on 9 and 10
Wewaii [24]
9.) The relation can not be a function only if the domain is the same. If you plot the points on a graph and use the Vertical Line Test(VLT) you would see that none of the points would be on the same line. It doesn't matter if the range is the same

10.)On the graph your y-intercept would be 2 so that is where you plot your first point. In order to find the slope you need to go up three spaces and one space to the left this is also known as "rise over run". *Remember you always go up spaces for "rise over run" but if the slope is positive then you go to the right and if its negative you go to the left.

I hope this helps love! :)
