White raven [17]3 years ago

Answer:

answer b (0.73)

Step-by-step explanation:

"Triple" means to increase in size by a factor of 3.  

Thus, B = (1 + r)^2 becomes

3 = (1 + r)^2.  Our task is to determine the value of r, the annual interest rate.

Taking the square root of both sides, we get

√3 = 1 + r, which yields √3 - 1 = r.

This is approx. 1.732 - 1.000, or 0.732.  Answer b) is closest.

Someone help me plz.
Svetllana [295]
Answer:
20%

Explanation:
What we know:
- there are 25 cans in total
- 5 of them are root beer cans

Using this information, we can say that 5/25 cans are root beer cans. To find the percent, we change the fraction into a decimal and then multiply it by 100.

To change 5/25 into a decimal, we divide the numerator and denominator.
5/25=0.2

And we multiply the decimal by 100 to get the percent:
0.2*100=20

Therefore, 20% of Cam’s cans are root beer cans.

I hope this helps!

Nadya [2.5K]

Answer:

7:24 pm

Time taken will be longer

Step-by-step explanation:

Given that:

Distance between Manchester and London = 195 miles

Departure time = 3.30 pm

Average speed of Coach = 50 mph

Arrival time in London :

Time taken = distance / speed

Time taken = 195 / 50 = 3.9 hours (3 hours (0.9 * 60) = 3 hours 54 minutes

= 3:30 pm + 3 hours 54 minutes = 7:24 pm

If the speed is Lower then the Timetaken will be longer and subsequently coach will arrive after 7:24 pm
