Find multiples of 30 and 40:

30: 30, 60, 90, 120, 150

40: 40, 80, 120, 160

The least common multiple is 120, so every 120 minutes they willl both ring.

1 hour = 60 minutes:

120/60 = 2 hours.

The bells ring together every 2 hours.

8 + 2  = 10 am

10 +  = 12pm

12 + 2 = 2 pm

The bells will ring together at am, 12 pm and 2 pm.

What was the cost of full coverage insurance in female in her 50s as a percentage of the same insurance in a male in his 30s if
ivolga24 [154]

Answer:

68.73%

Step-by-step explanation:

We have the insurance coverage amount for men of 30 years and for women of 50 years. Therefore, to find the percentage that represents the cost of coverage of the 50-year-old woman based on the cost of coverage of the man, we need to perform the following operation:

X_W = \frac{C_W}{C_M}*100\%

Where:

C_W: cost of coverage for a woman of 50 years.

C_M: coverage cost for a 30-year-old man.

X_W = \frac{\$819.73}{\$1192.64}*100\%

X_W = 68.73\%

Finally C_W represents 68.73% of C_W
