Answer:

The correct answer is:

C.) A triangular prism when sliced parallel to its base.

Step-by-step explanation:

We know that a triangular prism consists of 2 triangular shapes and three rectangular shapes.

  • We know that we can never obtain a cross-section similar to the base when the slicing is done perpendicular to it's base.
  • We know that when we slice a triangular pyramid parallel to the base than we will obtain a triangle of smaller dimensions.
  • But when we slice a triangular prism parallel to the  base than we obtain a cross-section that is similar to the base of a triangular prism.

Hence, the correct answer is Option: C)

To find the percent of the yellow tint in the new mixture?
Ivanshal [37]
1)We need to know the amount of yellow tint in the old mixture.

amount of yellow tint=30% of 40 liters
30%=30/100=0.3

Amount of yellow tint=0.3(40 liters)=12 liters.

2)We need to find the amount of yellow tint in the new mixture.

amount of yellow tint in the new mixture=12 liters + 9 liters=21 liters.

3) we calculate the amount of the new mixture:
amount of new mixture=40 liters + 9 liters=49 liters

4) we compute the percent of yellow tint in the new mixture:

percent of yellow tint =(amount of yellow tint / amount of mixture)*100

percent of yellow tint=(21 liters / 49 liters)100≈42.9%

Answer: The percent of yellow tint in the new mixture is 42.9%. 

note: if this answer is not correct you can try it  with 42.8%
