Answer:
The two watches will beep together for 20th time at 3:25 pm.
Step-by-step explanation:
My watch beeps every 15 seconds and mom's watch beeps every 25 seconds.
Thus both the watches beep at the same time at an interval of 75 seconds.
75 is the smallest multiple of 15 and 25.
They beep together at 3 pm and when they beep together for the 20th time , we have to add 20 times the time taken for both the watches to beep together.
This time interval = 20 75 = 1500 seconds = 25 minutes.
The two watches will beep together for 20th time at 3:25 pm.

<u>Given</u>:
The sides of the base of the triangle are 8, 15 and 17.
The height of the prism is 15 units.
We need to determine the volume of the right triangular prism.
<u>Area of the base of the triangle:</u>
The area of the base of the triangle can be determined using the Heron's formula.
Substituting a = 8, b = 15 and c = 17. Thus, we have;
Using Heron's formula, we have;
Thus, the area of the base of the right triangular prism is 36 square units.
<u>Volume of the right triangular prism:</u>
The volume of the right triangular prism can be determined using the formula,
where is the area of the base of the prism and h is the height of the prism.
Substituting the values, we have;
Thus, the volume of the right triangular prism is 450 cubic units.
