How long did Kajal speak on the phone?

Answers

Answer:

1 hour and 29 minutes

Step-by-step explanation:

4:50 pm to 6:00 pm is 1 hour and 10 minutes.

6:00 pm to 6:19 pm is 19 minutes.

1 hour and 10 minutes + 19 minutes = 1 hour and 29 minutes.

Explanation:

Let's find out how long Kajal spoke on the phone.

4:50 + 10 mins = 5:00

5:00 + 60 mins = 6:00

6:00 + 19 mins = 6:19

To find the total time between 4:50 + 6:19, we add the distances.

10 mins + 60 mins + 19 mins = 89 mins

Thus, Kajal spoke on the phone for 89 minutes.

A bacteria culture doubles every 5 hours. Determine the hourly growth rate of the bacteria
culture. Round your answer to the nearest tenth of a percent.

Answers

[tex]\sqrt[5]{2}-1 = 1 +x - 1[/tex]Answer:

14.87% per hour

Step-by-step explanation:

Let's pretend we're starting with one bacteria.

Double of one is two

We're gonna have to use this formula: A = P(1 + x)ⁿ

A = Amount (which is 2)

P = Initial amount (which is 1)

x = percentage per time (hour)

n = amount of time (hours)

So our equation will look like this:

2 = 1(1 + x)⁵

First, we need to root both sides to isolate (1 + x)

[tex]\sqrt[5]{2} = \sqrt[5]{(1+x)}[/tex]

[tex]\sqrt[5]{2} = 1 +x[/tex]

Then subtract both sides by 1

[tex]\sqrt[5]{2}-1 = 1 +x - 1[/tex]

[tex]x=\sqrt[5]{2}-1[/tex]

[tex]\sqrt[5]{2} = 1.148698355[/tex]

1.148698355 - 1 = 0.148698355

x = 0.148698355

A store is having a sale on CDs. Adrian buys five CDs and spends $40. If he decides to go back to the sale, and buy two more CDs, how much will he pay? How much with he pay for eight CDs?

Answers

Answer:

If Adrian buys 2 more CDs, he will pay $56.

Adrian will pay $64 for eight CDs.

Step-by-step explanation:

So, we already know that 5 CDs costs $40. That means that we can use this information to figure out how much 1 CD costs.

40 ÷ 5 = $8 per CD

Now that we know that each CD costs $8, we know that if Adrian buys 2 more CDs, then he will pay $16 ($8 x 2) more than his current price.

$40 + $16 = $56.

If Adrian buys 2 more CDs, he will pay $56.

Now, in order to find out how much 8 CDs costs, we just need to divide $8 by 8.

$8 x 8 = $64

Therefore, Adrian will pay $64 for eight CDs.
