A. PT and TQ are equal since they are both bisected by T. So, set them equal to each other you get the equation:
5x+3 =48
5x=45
x=9
The mass of brick is 2478 gram
<em><u>Solution:</u></em>
A brick is in the shape of a rectangular prism with a length of 8 inches, a width of 3.5 inches, and a height of 2 inches
Length = 8 inches
Width = 3.5 inches
Height = 2 inches
<em><u>The volume of rectangular prism is given as:</u></em>
![volume = length \times width \times height](https://tex.z-dn.net/?f=volume%20%3D%20length%20%5Ctimes%20width%20%5Ctimes%20height)
![volume = 8 \times 3.5 \times 2\\\\volume = 56](https://tex.z-dn.net/?f=volume%20%3D%208%20%5Ctimes%203.5%20%5Ctimes%202%5C%5C%5C%5Cvolume%20%3D%2056)
Thus volume of brick is 56 cubic inches
<em><u>Convert inches to centimeter</u></em>
1 inch = 2.54 centimeter
Therefore,
56 cubic inches = 56 x 2.54 x 2.54 x 2.54 cubic centimeter
56 cubic inches = 917.676 cubic centimeter
Thus, we get,
volume = 917.676 cubic centimeter
The brick has a density of 2.7 grams per cubic centimeter
Density = 2.7 grams
<em><u>The mass of brick is given by formula:</u></em>
![mass = density \times volume](https://tex.z-dn.net/?f=mass%20%3D%20density%20%5Ctimes%20volume)
<em><u>Substituting the values we get,</u></em>
![mass = 2.7 \times 917.676\\\\mass = 2477.724 \approx 2478](https://tex.z-dn.net/?f=mass%20%3D%202.7%20%5Ctimes%20917.676%5C%5C%5C%5Cmass%20%3D%202477.724%20%5Capprox%202478)
Thus mass of brick is 2478 gram
Answer:
A square
Step-by-step explanation:
They are both the same. There are 60 seconds in one minute, so 60*3 is 180. Since 180=180, they are equal.
