Tom has a water tank that holds 5 gallons of water.Tom uses water from a full tank to fill 6 bottles that each hold 16 ounces and a pitcher that holds 1/2 gallon.How many ounces of water are left in the water tank?

Answers

Answer 1
Answer:

Answer:

503.525 gallon ( approx )

Step-by-step explanation:

Given,

Water hold by of the water tank = 5 gallon

We know that, 1 gallon = 133.228 ounces

⇒ Water hold by of tank in ounces = 5 × 133.228 = 666.139 ounces,

Here, it is given that, 6 bottles that each hold 16 ounces and a pitcher that holds 1/2 gallon is used from tank,

Since, the quantity of water hold by6 bottle in which each hold 16 ounces = 6 × 16 = 96 ounces,

Also, 1/2 gallon = 1/2 × 1 gallon = 1/2 × 133.228 = 66.614 ounces

Thus, the total consumed water = 96 + 66.614 = 162.614 gallon

Hence, the quantity of water left in the tank = Water hold by of tank in ounces - the total consumed water

= 666.139 - 162.614

= 503.525 gallon
Answer 2
Answer: 1 gallon is 128 ounces, 5 gallons is 640 ounces. So 6*16=94 ounces Pitcher equals 64 ounces, so 640-158=452, there are 452 ounces of water left

Which of the following relations is a function?A. (2,4), (-5, 6), (2, 3), (-6, 2)
B. (8, 1), (-5, 4), (2, 1), (8, 2)
C. (2,4), (-5, 2), (8, 1), (-6, 2)
D.
(2,0).(-5, 3), (8, 1), (-5,5)

Answers

Answer: OPTION C

Step-by-step explanation:

A relation is a function when each input value has one and only output value.

For option A:

 (2,4), (-5, 6), (2, 3), (-6, 2)

You can observe that the input value "2" has two output values. Then it is not a function.

For option B:

(8, 1), (-5, 4), (2, 1), (8, 2)

You can observe that the input value "8" has two output values. Then it is not a function.

For option C:

(2,4), (-5, 2), (8, 1), (-6, 2)

You can observe that each input value has only one output values. Then it is a function.

For option D:

(2,0).(-5, 3), (8, 1), (-5,5)

You can observe that the input value -5 has two output values. Then it is not a function.

For a set of data to be a function each x value has to have different y values.

A. (2,4), (-5, 6), (2, 3), (-6, 2)

B. (8, 1), (-5, 4), (2, 1), (8, 2)

D.(2,0).(-5, 3), (8, 1), (-5,5)

The bolded coordinates are the ones of each data set that makes it not a function. As you can see the x values all have different y values.

This leaves C. as the answer!

Fuel economy estimates for automobilos built in a certain yoar predicted a mean of 26.8 mpg and a standard deviation of 72 mpg for highway driving. Assume that a normal distribution can be applied. Within whatrange are 99.8% of the automobiles?

Answers

Answer:

range=u ± 3.09 sd

Step-by-step explanation:

Given:

mean, u= 26.8 mpg

standard deviation, sd=72 mpg

% contained in interval = 99.8%

the interval for 99.8% of the values of a normal distribution is given by

mean ± 3.09 standard deviation= u ± 3.09 sd

                                                      =26.8  ± 3.09(72)

                                                      =26.8 ± 222.48

                                                      = 249.28 , -195.68

range=u ± 3.09 sd = 249.28 , -195.68 !

Your first instinct was to multiply it out and get rid of the parentheses. 
That's often a good instinct, but this time, it made things harder for you.

This is a good example of a rule you should consider: 

         Before you do anything to anything, sit back, relax,
         LOOK at the problem, THINK about it, and plan your
         strategy.  Decide what the solution might look like,
         and what you're going to do to the given information
         in order to move towards the solution.

You might look at this particular equation and ponder:

-- If I multiplied this thing out and got rid of the parentheses, it would
have x³ in it.  So there are going to be 3 solutions.

-- If either factor is zero, then the equation is true.

-- One of the factors is 6x.  Setting that to zero gives one solution: x=0.

-- The other two solutions come from setting   (4x² - 4) = 0 .

-- That's the difference of 2 squares, so it's    (2x + 2) (2x - 2) = 0

-- The other 2 solutions come from setting each of those factors to zero.

There you are.  You got this far just by thinking, without even picking up
your pencil yet.
6x( 4x^2 -4) = 0 
then 6x = 0  --- eqn.1
or (4x^2-4) = 0 --- eqn.2 
from eqn.1 we get that x=0 
from eqn.2 we get:
4x^2=4
x^2=1
x^2 - 1 =0 
(x-1) * (x+1) = 0 
so x = +1 and -1 
the final answer is x= 0, -1 , 1
