Answer: 144 times

Step-by-step explanation:

In 30 seconds , it beats 36 times

Another 30 seconds - 36 times

Another 30 seconds - 36 times

Another 30 seconds - 36 times

Therefore , in two minutes , it will beat , 36 + 36 + 36 + 36 times

Therefore , it will beat 144 times .

Another Approach

30 Seconds - 36 times

1 second - 36/30 times

Since 120 seconds make 2 minutes , then

120 seconds - 36/ 30 x 120

= 144 times

Factor 15 + 50.<br> 5(10 + 3)<br> 5(3 + 10)<br> 3(5 + 25)<br> 10(5 + 5)
Agata [3.3K]

Answer:

B

Step-by-step explanation:

So we have the expression:

15+50

Since 5 goes into both 15 and 50, we can factor out a 5. First, rewrite the numbers as:

5(3)+5(10)

Factor out the 5:

=5(3+10)

So, our answer is B

And we're done!
