One analog clock loses 3 minutes every 2 hours and another analog clock gains 3 minutes every 4 hours. At noon, the owner sets the correct time on both clocks and leaves on a business trip. When he returns home in less than two weeks, the clocks show the same time. What time do the clocks show? PLEASE HELP ASAP

Answers

Answer 1

Answer:

12 noon

Step-by-step explanation:

Clock 1 loses 3 minutes every 2 hours. Now, 2 hours = 120 minutes.

This means, it has speed of 120 - 3 = 117 minutes for every 2 hours.

Thus, in 1 hours, it's speed = 117/2 = 58.5 min/hr

Clock 2 gains 3 minutes every 4 hours

Which means in an hour, it gains ; 4/3 minutes

Thus, it's speed an hour is; 60 + 4/3 = 61.333 min/hr

Now, When he returns home in less than two weeks, the clocks show the same time.

let's say the number of hours he was away is x. For the 2 clocks to show the same time, it means they have to show it by 12 noon at another day since it was at noon that he set the correct times before leaving.

Thus, they will both be showing 12 noon.

Twenty distinct cars park in the same parking lot every day. Ten of these cars are USmade while the other ten are foreign-made. The parking lot has exactly twenty spaces all in a row so the cars park side by side. However, the drivers have varying schedules so the position any car might take on a certain day is random. What is the probability that on a given day, the cars will park in such a way that they alternate (i.e., no two US-made cars are adjacent and no two foreign-made cars are adjacent)?

Answers

Answer:

The probability that on a given day, the cars will park in such a way that they alternate is 1.0825 × 10⁻⁵.

Step-by-step explanation:

It is provided that the cars will be parked in such a way that they will be alternating: US made, foreign made, US made, foreign made, etc.

First park all the US cars. This can be done in 10! ways, since the cars are distinct.  

Now park the foreign cars between the US cars. This can also be done in 10! ways.  

Since the sequence could begin either with a US car or with a foreign car, the possible number of ways to park alternating cars is

Favorable Outcomes = 2 × 10! × 10!

The total number of ways to park the 20 distinct cars is,

Total Outcomes = 20!

Compute the probability that on a given day, the cars will park in such a way that they alternate as follows:

[tex]P(\text{Alternate Parking})=\frac{\text{Favorable Outcomes}}{\text{Total Outcomes}}[/tex]

                                  [tex]=\frac{2\times 10!\times 10!}{20!}\\\\=\frac{2\times 10!\times 10!}{20\times 19\times 18\times ...10!}\\\\=\frac{2\times 10!}{20\times 19\times 18\times ...11}\\\\=1.0825\times 10^{-5}[/tex]

Thus, the probability that on a given day, the cars will park in such a way that they alternate is 1.0825 × 10⁻⁵.

Answer:

y=1/6x-7/6

Step-by-step explanation:

-6y = -x + 7

y = x/6 - 7/6

This is assuming you mean in standard form.

Also, you may have to write it as 'y=1/6x-7/6'

Without using a calculator, order the following expressions from least to greatest.

Answers

Here we want to order from least to greatest the following expressions:

7.12 = 7.121212...

√75

√45

We will find that the order is: √45 < 7.12 < √75

remember that:

√x = y

such that:

y*y = x

From this, is easy to see that:

√45 < √75

Now to see where 7.1212... enters, we need to compute:

(7.1212...)*(7.1212...) = (7 + 0.1212...)*(7 + 0.1212...)

                               = 7*7 + 2*7*0.121212... + 0.1212...*0.1212...

                               = 49 + 2*7*0.121212... + 0.1212...*0.1212... > 45

So we know for sure that:

7.12 > √45

And 8*8 = 64 < 75

then:

7.12 < 8 = √64 < √75

For transitivity, we have:

7.12< √75

Then the order, from least to greatest, is:

√45 < 7.12 < √75

Exponential Function:

A population of bacterium in laboratory conditions grows every 20 minutes in 10% the number of specimens. At the beginning of the observation, at 8:00 AM, the population had approximately 3,000,000 individuals:

1. Complete the following attached table (table below) as requested by completing each of the blank boxes.

2. What is the approximate population of bacterium at 10:00 AM?

3. Write the function in power form, indicating which is the dependent and independent variable.

4. Using the function found, determine the bacterial population five hours after the start of the observation.

Answers

Answer:

See below

Step-by-step explanation:

GivenInitial population at 8:00 AM3000000Growth rate = 10% = 1.1 times per 20 minSolution

1. Table

Note. I am not sure what are the last 3 rows. Just added next 3 terms.

8:00  ≡  G(0)   ≡   3000000              ≡  30000008:20  ≡  G(1)    ≡   3000000 *1.1        ≡  33000008:40  ≡  G(2)   ≡   3000000 *1.1^2    ≡  36300009:00  ≡  G(3)   ≡   3000000 *1.1^3    ≡  39930009:20  ≡  G(4)   ≡   3000000 *1.1^4    ≡  4392300

2. Population at 10:00

Time passed since 8:00 is 2 hours = 2*3*20 min = 6* 20 minPopulation = 3000000*1.1^6 = 5314683

3. Function to reflect the population growth

G(x) = 3000000*1.1^xG(x) - is dependent variable, population of bacteriax - is independent variable, time increment of 20 min

4. Population after 5 hours

The value of 8 in 8596 is blank the value of 8 in 985

Answers

The value of 8 in 8596 is 100 times the value of 8 in 985

To do this type of problem we can really sound them out. What I mean by that is say where the 8 is in particular.

When you look at 8596 you say eight THOUSAND. Therefore it is in the thousand spot. Now look at 985 you say nine hundred and EIGHTY five. Because we know that it isn’t in the hundreds spot because 9 is in it then we go to the next value which is the 10’s spot.

Now we want to look at the difference between the 1000 and 10 spot. How do you get 10 to 1000? Multiply by 100 and add two zeros to therefore get 1000. This would mean that the value of 8 in 8596 is 100 times the value of 8 in 985.
