Answer:

19.209372712298546 (C)

Step-by-step explanation:

For this you use pythagorean theorem. a squared + b squared = c squared which is your missing side. 15 squared is 225 and 12 squared is 144 so together thats 369. Now we know c squared is 369 so we find the square root of that and boom. So your answer is C (19.2)

A red light blinks every 12 seconds and a blue light blinks every 9 seconds. When will both lights blink at the same time?

mote1985 [20]

Answer:

Step-by-step explanation:

We need to find the LCM of the two numbers because we need to know the lowest number that 12 and 9 are both in.

12 × 1 = 12

12 × 2 = 24

12 × 3 = 36

12 × 4 = 48

9 × 1 = 9

9 × 2 = 18

9 × 3 = 27

9 × 4 = 36

We can see that 36 is the lowest number that occurs both in 12 and 9 so the blue and red light will both link at 36 seconds

List the single-digit divisors of 2100. I really need help

liberstina [14]

Answer:

1, 2, 3, 4, 5, 6, 7

Step-by-step explanation:

Prime factors of 2100 are:

2100 = 2*2*3*5*5*7

The single-digit divisors are:

1, 2, 3, 2*2= 4, 5, 2*3= 6, 7

-----------------------------------------------------------------

Another solution is you divide 2100 by all numbers 1 through 9 and list those divisible:

2100/1 = 2100, yes
2100/2 = 1050, yes
2100/3 = 700, yes
2100/4 = 525, yes
2100/5 = 420, yes
2100/6 = 350, yes
2100/7 = 300, yes
2100/8 = 262.5, no
2100/9 = 233.33, no

So all the numbers from 1 to 7
