Answer:
1) OPTION D.
2) OPTION D.
Step-by-step explanation:
1) You can calculate the surface area of the rectangular prism with the following formula:

Where w is the width, h is height and l is the length.
The figure show you that:

Then, the surface area is:
![SA=2[(3m*0.5m)+(4m*3m)+(4m*0.5m)]=31m^{2})](https://tex.z-dn.net/?f=SA%3D2%5B%283m%2A0.5m%29%2B%284m%2A3m%29%2B%284m%2A0.5m%29%5D%3D31m%5E%7B2%7D%29)
2) You can calculate volume of the rectangular prism with the following formula:

Where w is the width, h is height and l is the length.
When you substitute values, you obtain the following result:

Answer: A
The y-intercept is 43, which means that at 0 hours it was 43 degrees. The slope is -2 so it means that the temperature is decreasing at a rate of 2 degrees per hour.
1 mm is .1 cm, so 2 mm would be .1*2=.2 cm.
Answer:
Below in bold.
Step-by-step explanation:
cos x = adjacent side / hypotenuse
= 8/21
= 0.380952
So m < x = arccos 0.380952
= 67.607
= 68 degrees to nearest degree.
S ok by brother your we’ll
