Sam cleaned 1/3 of his house in 50 minutes. How many hours will it take him to clean his entire house?

please give me the correct answer and full explanation ​

Answers

Answer:  2.5 hours

This is equivalent to equivalent to 2 hours, 30 minutes.

======================================================

Work Shown:

1/3 of the house = 50 minutes

3*(1/3 of the house) = 3*(50 minutes)

3/3 of the house = 150 minutes

1 house = 150 minutes

-----------

Sam will need 150 minutes to clean the whole house

Divide this over 60 to convert to hours

150 minutes = (150/60) hours

150 minutes = 2.5 hours which is the final answer

-----------

Or you could say the following

150 minutes = 120 min + 30 min

150 minutes = (120/60) hr + 30 min

150 minutes = 2 hr + 30 min

This shows that 2.5 hours is equivalent to 2 hours, 30 minutes.

The time it takes to clean up after an anniversary party varies inversely as the number of people cleaning. If 3 people work together to clean, it will take them 90 minutes. How long will it take if the number of people cleaning is increased to 5?

Answers

Answer:

54minutes

Step-by-step explanation:

Let the time taken to clean up be t

Let the number of people cleaning be n

If the time it takes to clean up after an anniversary party varies inversely as the number of people cleaning then;

t = k/n

k is the constant of proportionality

If 3 people work together to clean, and took them 90 minutes, this means

at t = 90, n=3

Substitute

90 = k/3

k = 3×90

k = 270

To et the time it will take 5people to clean, the will say;

t =k/n

t =270/5

t = 54 minutes

Hence it will take 5 people 54minues to clean

Answer: 54 minutes

Multiply (1) by 2,

Subtract (2) from (3),

4x - 4x + 6y + y= 26 + 2

7y = 28

y = 4

Determine the equation of the line satisfying the following condition.
Containing the point (-1,-5) and parallel to 3x+2y=9

Answers

Answer: y=-3/2x-13/2

Step-by-step explanation:

To find a line parallel to the given line, we know that the two equations must have the same slope. We first want to find the slope of the given equation.

3x+2y=9             [subtract both sides by 3x]

2y=-3x+9            [divide both sides by 2]

y=-3/2x+9/2

Now, we know the slope if -3/2. All we have to do is plug in the given point to find the y-intercept.

-5=-3/2(-1)+b      [multiply]

-5=3/2+b            [subtract both sides by 3/2]

b=-13/2

Now, we know the equation is y=-3/2x-13/2.

Y=-3/2x-13/2 is definitely the answer

The random variable X takes on the values of 2, 5, n, and 15. The probability distribution of X is shown in the following table

Answers

The question is missing some parts. Here is the complete question.

The random variable X takes on the values of 2, 5, n and 15. The probability distribution of X is shown in the table below.

The expected value of X is 9.1. What is the value of n?

a) 8

b) 8.52

c) 10

d) 12

e) 14.4

Answer: d) 12

Step-by-step explanation: In a probability distribution, Expected Value is the average (or mean) value a distribution can assume.

The Expected Value, E(X), can be determine by:

[tex]E(X)=\Sigma xP(x)[/tex]

in which

x is how many times an event happens

P(x) is the probability of an event happening

The table below n is x and expected value is 9.1, then:

[tex]9.1=2*0.1+5*0.4+0.2n+15*0.3[/tex]

[tex]9.1=0.2n+6.7[/tex]

[tex]0.2n=2.4[/tex]

n = 12

Value of n in this probability distribution is 12.

The value of n in the discrete probability distribution given is 12.

The the sum of [P(X) × X] in a discrete probability distribution is the expected value

From the discrete probability table given :

P(X) × X can be expressed as :

E(X), expected value = 9.1

(0.1 × 2) + (5 × 0.4) + (15×0.3) + 0.2n = 9.1

0.2 + 2.0 + 4.5 + 0.2n = 9.1

6.7 + 0.2n = 9.1

0.2n = 9.1 - 6.7

0.2n = 2.4

n = 2.4 / 0.2

n = 12

Therefore, the value of n in the table is 12
