Answer:

The amount Trevor's family pay per minute on shower water is $0.005.

Step-by-step explanation:

The cost of water is,

Cost = $0.20/liter

Amount of water used over the entire month:

Amount of water used = 72 liters

Compute the total water cost as follows:

Total water cost = Amount of water used × Cost

                           = 72 × 0.20

                           = $14.4/liter

The average number of minutes each person showered is:

Average number of minutes = 480 minutes.

The number of people in Trevor's house:

N = 6

Compute the total amount of time the 6 person showered as follows:

Total amount of time = Average number of minutes × N

                                   = 480 × 6

                                   = 2880 minutes

Compute the pay per minute on shower water as follows:

Pay per minute on water = Total water cost ÷ Total amount of time

                                          = $14.4 ÷ 2880

                                          = $0.005

Thus, the amount Trevor's family pay per minute on shower water is $0.005.

In order to solve for the variable in the equation 2(x+3)+ 5x = 3(2x-1), Jaleesa begins by applying the distributive property,
abruzzese [7]

Answer: 7x+6 = 6x-3

Step-by-step explanation: Lets begin by applying the distributive property and then combining like terms to see what the result of these steps will look like.

2(x+3)+5x = 3(2x-1)

Apply the distributive property: 2 x X = 2x and 2 x 3 = 6 and 3 x 2x = 6x and 3 x -1 = -3

2x+6+5x = 6x-3

Combine Like Terms: 2x + 5x = 7x

7x+6 = 6x-3

ANSWER TO QUESTION 1

The set of natural numbers that are factors of 20 are natural numbers that divides 20 exactly without a remainder.

These natural numbers are;

{1,2,4,5,10,20}

Therefore the correct answer is D

ANSWER TO QUESTION 2

Given that the universal set U has elements

{1,2,3,4,5,6,7,8,9,10}

and the set P also has elements

{2,4,6,8,10}

The elements of P' are the elements that are in the universal set but are not in set P.

These elements are;

{1,3,5,7,9}

The correct answer is C

ANSWER TO QUESTION 3

The distance is given by the absolute value equation

d=|130-25t|

If the is 15 feet away then d=15

This implies that;

15=|130-25t|

We now split the absolute value sign to obtain,

15=130-25t

or

-15=130-25t

We now solve for t to obtain;

15-130=-25t

or

-15-130=-25t

\frac{115}{25}=t

or

\frac{145}{25}=t

This gives us

4.6=t

or

5.8=t

The correct answer is C

ANSWER TO QUESTION 4

Given

P={0,1,2,3,4,56,7,8,9}

and

V={2,4,6,810,1216,18,20}

P\capV={2,4,6,8}

P\V are  elements in P only .

This means that we have to take out the elements of the intersection of the two sets from P.

P\V ={0,1,3,5,5,7,9}

The correct answer is B

ANSWER TO QUESTION 5

The correct answer is B.

In listing the elements of a set, we do not repeat the element. In order words we list only distinct elements.


Blueberry is repeating in both sets but we have to list it once.

ANSWER TO QUESTION 6.

The correct answer is 220

We were told that 250 play basket ball

If 120 play both sports, then

250-120=130

play only basketball

Now the number of people who play only baseball

350-250=100

But the number of people who play baseball

120+100=220

Which complex number has a distance of 17 from the origin on the complex plane?
Virty [35]

Answer:

None of the options are correct.

Step-by-step explanation:

Let the complex number is a + ib

Given distance from origin = 17 units

Now, by distance formula distance of a point  from the origin  =

17 = \sqrt{(x)^{2}  + (y)^{2} }

1) <u>Check for 2 + 15 i</u>

here, \sqrt{15^2  +  2^2}  = \sqrt{225 + 4} = \sqrt{229} ≠ 17

2)<u> Check for 17 +  i</u>

here, \sqrt{17^2  +  1^2}  = \sqrt{289 + 1} = \sqrt{290}≠ 17

3)<u> Check for 20 - 3 i</u>

here, \sqrt{20^2  +  (-3)^2}  = \sqrt{400 + 9} = \sqrt{409}≠ 17

4) <u>Check for 4 -  i</u>

here, \sqrt{4^2  +  (-1)^2}  = \sqrt{16 + 1} = \sqrt{17} ≠ 17

Hence,  none of the options are correct.

HELP PLEASE!!
Morgarella [4.7K]

Answer:

Yes! This is my area!

Step-by-step explanation:

Minimum= 51

Maximum=64

To find the median put the numbers in order

51,53,55,58,60,60,64

no cross off one by one to get the middle number

you end up with 58

first quartile is the upper half so that would be 53

third quartile is the lower half so that wou;d be 60

Hope this helps!
