Answer:
At 5:15 PM , they will ring together.
Step-by-step explanation:
We have been given that first bell rings every 15 minutes and second bell rings at every 25 minutes.
In order to find when both will ring together again, we can find the LCM of these two numbers.
15 = 3 × 5
25 = 5 × 5
Therefore, LCM of these two numbers is
LCM = 5 × 5× 3
LCM = 75
Hence, 75 minutes = 75/60 = 5/4 hours
Therefore, at 5:15 PM , they will ring together.
The sum of the perimeters of two congruent triangles is TWO times the perimeter of one of them.

<u>Sometimes</u> is the answer. Hope I helped..
All factors of 12 are {-12, -6, -4, -3, -2, -1, 1, 2, 3, 4, 6, 12}, so x is one of these numbers.
t is a prime, so t∈{2, 3, 5, 7, 11, 13, 17, 19, 23....}
A) t/x cannot be 1/12, because 1 is not a prime. NOT POSSIBLE
B) 1/4 = 3/12 ...... 3 is a prime and 12 is a factor of 12. POSSIBLE
C) 1/2= 3/6 .....3 is a prime and 6 is a factor of 12. POSSIBLE
D) 1 = 2/2....... 2 is a prime and 2 is a factor of 12. POSSIBLE
E) 2 = 2/1 ....... 2 is a prime and 1 is a factor of 12. POSSIBLE
Answer: A
She could use a pyramid mold or a cube mold. This is because the bases
of those shapes are squares, even thought the actual figure is not.
Think of the pyramids in Egypt, they look triangular, but the base is
square. I'm sure there are more possible molds that you could use, but
those are just a few of the simple ones. I hope this helps! :)
