A shipping container is in the shape of a right rectangular prism with a length of 13.5 feet, a width of 4 feet, and a height of
podryga [215]

Answer: 227 pounds.

Step-by-step explanation:

By definition, the volume of a rectangular prism can be calculated with the following formula:

V=lwh

Where "w" is the width of the rectangular prism, "l" is the length and "h" is the height of the rectangular prism.

In this case you know that:

l=13.5\ ft\\\\w=4\ ft\\\\h= 7.5 ft

Substituting values into the formula, you get that the volume of the shipping container is:

V=(13.5\ ft)(4\ ft)( 7.5 ft)\\\\V=405\ ft^3

You know that it was completely filled with  contents that weigh 0.56 pound per cubic foot, approximately. Then, its density is:

d=0.56\ \frac{lb}{ft^3}

Since:

d=\frac{m}{V}

Where "m" is mass and "V" is volume, you can susbstitute values and solve for "m":

0.56\ \frac{lb}{ft^3}=\frac{m}{405\ ft^3}\\\\(0.56\ \frac{lb}{ft^3})(405\ ft^3)=m\\\\m\approx227\ lb

Can you guys help me​
Fudgin [204]

Answer:

The answer is 76.

Step-by-step explanation:

≅ means to be equal to.

☆Angle DGE ≅ EGF.

Therefore, 3x + 8 = 5x - 12

☆Let's solve that equation.

3x  + 8 = 5x - 12 \\  \frac{ - 5x \:  \:  \:  \:  \:  \:  \:   =  - 5x  \:  \:   \:  \:   \: \:  \:  \: }{ - 2x + 8 =  - 12}  \\  \frac{  \:  \:  \:  \:  \:  \:  \:  \: - 8  =  - 8}{  \frac{ - 2x}{ - 2}  =  \frac{ - 20}{ - 2} }   \\ x = 10

We found the value of x which is 10.

☆Let's Now plug in.

DGE \\ 3x + 8 \\ 3(10) + 8 \\ 30 + 8 \\ 38

and the other:

EGF \\ 5x - 12 \\ 5(10) - 12 \\ 50 - 12 \\ 38

☆They asked for what the angle of DGF measured. So we would have to add both sides

38 + 38 = 76

☆The answer is 76

The bill is $100.99. You want to leave a 20% tip. How much should the tip be?
Arisa [49]

Answer:

$20.20

Step-by-step explanation:

First Convert 20% into a decimal, by dividing it by 100

Percent = out of 100

20/100 = 0.2

Now, multiply the decimal (0.2) with the bill amount ($100.99):

0.2*100.99

$20.198 <== *remember, we are using money, so we round to the nearest cent (dime)

$20.20 <== how much tip you want to leave

How much you pay altogether:

(Bill + tip)

100.99 + 20.20

$121.19

Hope this helps!
