Answer:

~12 meters per second is your answer

Step-by-step explanation:

You need to do these specific things in order to convert.

Kilometers to meters - Multiply by 1000

Minutes to Seconds - Multiply by 60.

_______________________________________________________

First, do 20 kilometers multiplied by 1000

20 x 1000 = 20,000 meters

Do 29 minutes multiplied by 60.

29 x 60  = 1,740 seconds

_______________________________________________________

Now that we have everything converted, you need to divide it to find the speed.

Speed is Distance over Time.

20,000 meters / 1,740 seconds = Speed

Do 20,000 divided by 1,740

11.494252873563218390804597701149 That is your number.

You need to round that to the nearest whole number.

Answer:

15 minutes.

Step-by-step explanation:

One hour is equal to 60 minutes. Since you're asking for 1/4, or a quarter, of that amount of time, we should divide 60 by four.

Using a calculator, you'd get 15 asap. Without one, if you can divide 60 in half (that equals 30), then divide that half in half again (that equals 15), you'll have divided it into quarters and gotten your answer.

Answer:

t = 7

Step-by-step explanation:

total cost = 35

price per adult = 14x -> only 1 adult so 14(1) = 14

35 = 14(1) +3t

35-14 = 3t

Step-by-step explanation:

The answer is D) 0.99218

The probability that the person will not die in the next year is approximately 0.99218.

Option D is the correct answer.

It is the chance of an event to occur from a total number of outcomes.

The formula for probability is given as:

Probability = Number of required events / Total number of outcomes.

Example:

The probability of getting a head in tossing a coin.

P(H) = 1/2

We have,

The probability that a person will die in the next year is 782/100000.

To find the probability that the person will not die in the next year, we can subtract the probability of dying from 1, since the sum of the probabilities of dying and not dying is always 1.

1 - 782/100000 = 99218/100000

This fraction can be simplified by dividing both the numerator and the denominator by their greatest common factor, which is 2:

99218/100000

= 49609/50000

This fraction can be converted to a decimal by dividing the numerator by the denominator:

= 49609/50000

= 0.99218

Therefore,

The probability that the person will not die in the next year is approximately 0.99218.

Using proportions, it is found that 375 products are produced with 15 workers in 5 hours.

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

In this problem, we have that the rule of three are given as follows:

1000 products - 20 workers - 10 hours.

x products - 15 workers - 5 hours.

The measures are direct proportional, hence:

[tex]\frac{1000}{x} = \frac{20}{15} \times \frac{10}{5}[/tex]

[tex]\frac{1000}{x} = \frac{40}{15}[/tex]

Applying cross multiplication:

40x = 15(1000)

x = 15(1000)/40

x = 375.

375 products are produced with 15 workers in 5 hours.

Answer:

In the picture is how to solve it

Step-by-step explanation:

Answer:

We are multiplying sin theta by sec theta, so we first start with valuing sec theta. Re-evaluate sec theta as sec(theta), and get the reciprocal.

[tex]sin(theta) * \frac{1}{cos(theta)}[/tex] <-- reciprocal

Combine sin() with the reciprocal of sec theta.

[tex]\frac{sin(theta)}{cos(theta)}[/tex]

Rewrite this combination as tan(theta)

[tex]tan(theta)[/tex]

Since the sides are equal, they count as an identity.

[tex]sin(theta) * sec(theta) = tan(theta)[/tex]

That said, sin(theta) × sec(theta) = tan(theta) is an identity.

An equation is formed of two equal expressions. The equation of the new graph will be y=|1/(2x-4)|+3.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

The equation given is  [tex]y=\left|\dfrac{1}{2x-2}\right|+3[/tex], which is needed to be translated 1 unit to the right therefore, the value of x should be decreased by 1. Therefore, the equation of the new graph will be,

[tex]y=\left|\dfrac{1}{2(x-1)-2}\right|+3\\\\\\y=\left|\dfrac{1}{2x-2-2}\right|+3\\\\\\y=\left|\dfrac{1}{2x-4}\right|+3[/tex]

Hence, the equation of the new graph will be y=|1/(2x-4)|+3.

The pressure to the nearest tenth at the time of the first measurement  for this case was 1.82 atm approximately.

According to the Boyle's law, the pressure of a gas tends to drop as the capacity of the container increases. We can write it symbolically as:

[tex]P_1V_1 = P_2V_2[/tex]

where we have:

[tex]P_1[/tex] and [tex]V_1[/tex] are first pressure and first volume, and:

[tex]P_2[/tex] and [tex]V_2[/tex] are second pressure and second volume.

The complete question is:

" According to Boyle's law, PV = k, what was the pressure to the nearest tenth at the time of the first measurement given the following information?

V₁ = 7,450 mL, P₂ = 8.25 atm, V₂ = 1,645 mL"

So, using the Boyle's rule, we get:

[tex]P_1V_1 = P_2V_2\\\\P_1 = \dfrac{P_2V_2}{V_1}\\\\P_1 = \dfrac{8.25 \times 1645}{7450} \approx 1.82 \: \rm atm[/tex]

Thus, the pressure to the nearest tenth at the time of the first measurement  for this case was 1.82 atm approximately.

where:

If b > 1 then it is an increasing function

If 0 < b < 1 then it is a decreasing function

Given:

If the number of phones decreased by 14% each year, then each year the number of phones will be 86% of the previous year
