If there were 300 accidents in 1967 and 380 in 1968, what is the percent increase?

Answers

Answer:

As per the statement:

If there were 300 accidents in 1967 and 380 in 1968.

Number of accident in 1967= 300

Number of accident in 1968= 380

then;

Increase in accident = 380-300 = 80

Using formula to find the percent increase:

$\text{Increase in percent} = \frac{\text{Increase in accident}}{\text{Number of accident in 1967}} * 100$

Substitute the given values we have;

$\text{Increase in percent} = (80)/(300) * 100$

Simplify:

$\text{Increase in percent} = (80)/(3) = 26(2)/(3) \%$

Therefore, $26(2)/(3) \%$ is the percent increase

First find the amount of increase: 380-300=80. Then divide the amount of increase by the original amount: 80/300=.266666667. Normally you round to the tenths place: .27. Then make it a percent: .27=27%. The percent of increase is 27% :) hope this helps

A ship is about to sink in 20 minutes with 15 people on board. A nearby island and a boat are their only escape, but the boat can only carry 5 people at a time. It takes a total of 9 minutes for the boat to go from the ship to the island and back. People can't swim due to the threat of sharks. How many people would survive and reach the island?

Answers

10 people will reach the island and survive

Final answer:

Considering the time constraints of the situation, only 2 trips can be made before the ship sinks. Therefore, only 10 people, as the boat carries 5 per trip, can reach the island alive.

Explanation:

This question is a mathematical problem that can be solved by considering the time constraints. To start, we know that the boat can carry 5 people at a time and it takes 9 minutes to go from the ship to the island and back.

This means that only 5 people can be transported to the island every 9 minutes.

However, the ship will sink in 20 minutes, so the boat will only be able to make 2 trips - one at the beginning, and the second after 9 minutes. Therefore only a total of 10 people (5 people per trip) will be able to reach the island before the ship sinks.

Need help in solving this problem. Section is under limits at infinity, horizontal asymptotes...(a) A tank contains 5000L of pure water. Brine that contains 30g of salt per liter of water is pumped into the tank at a rate of 25L/min. Show that the concentration of salt after t minutes (in grams per liter) is
C(t)+ 30t/200+t
(b) what happens to the concentration as t--> infinity?

Answers

(a) you can show the concentration by:

amount of salt / amount of water

amount of salt

= 30g / L

= [ 30 * 25g ] / [ 25L ] , 25L = 1 min

= [ 30 * 25g ] / min

amount of water

= 5000 + 25t

[ 30 * 25t ] / [ 5000 + 25t ]

= [ 30 * 25t ] / 25*[ 200 + t ]

= 30t / [ 200 + t ] yeah

(b)

lim t->∞ [ 30t / ( 200 + t ) ]

= lim t->∞ [ ( (1 / t) * 30t ) / ( (1 / t) * ( 200 + t ) ) ]

= lim t->∞ [ 30 / ( (200 / t) + 1 ) ]

= 30 / ( (200 / ∞) + 1 )

= 30 / 1

= 30

A phone company charges $25 per month, plus an installation fee of $50. If you have paid the phone company $375, how many months have you had the phone?

Answers

The total bill was inclusive of the one-time payment of $50 and an additional payment of $25 per month. The only unknown variable here is the amount of months you've had the phone. This can be solved by isolating the unknown variable, like so:

Let: x = number of months

Total bill = one-time payment + monthly payment * number of months
$375 = $50 + $25x
375 - 50 = 25x
325 = 25x

325/25 = 25x/25
x = 13

Therefore, you've had the phone for 13 months.
