<span>From your situations given:
If there is 1 child, there can be 0 interactions.
If there are 2 children, there can be 3 interactions.
If there are 3 children, there can be 12 interactions.
If there are 4 children, there can be 39 interactions.

The equation would be <span>an = an – 1 + 3(n – 1)
</span>
Kim's age would be 24 and her sister would be 12 since her sisters' age is half of hers x would need to be multiplied by 1/2 to get her age.
x + x(1/2)=36 where x is 24
24 + 24(1/2) = 36
24 + 12=36
Answer:
0.625
Step-by-step explanation:
Given :
Ambell company uses or procures batteries from two manufacturers.
The life of a battery in critical tool is at = 32 hours
Ambell uses 70% of its batteries from manufacturer 1 and out of that 90% batteries lasts for about 40 hours.
Similarly, 75% of the batteries procured from the manufacturer 2 lasts for about 40 hours.
Therefore, the probability that a battery is form manufacturer 1 is :
= 0.625
Answer:
Step-by-step explanation:
Let x represent the number of miles after which the cost of both options will be the same.
You have two payment options. Option A is to buy a monthly pass for $30 and pay $0.80 per ride. This means that the total amount that you would pay for x miles if you use this option is
0.8x + 30
Option B is to pay $2.30 per ride. This means that the total amount that you would pay for x miles if you use this option is
2.3x
An equation to show after how many rides the cost will be the same would be
0.8x + 30 = 2.3x
2.3x - 0.8x = 30
1.5x = 30
I think it’s 1,270.246376811594 :)
