Suppose someone opens the valve on a large water tank so that water drains out. Choose a starting volume of water in the tank (from 100 to 500 gallons), and choose how much water drains out each day (from 2 to 5 gallons). Write the equation that models the relationship between time (x) and water volume (y) in slope-intercept form.

Answers

Answer 1

If we are to choose any number from 100 to 500, you may take any other number but for the purpose of showing how things are done here, let me choose 100 gallons. Similarly, we choose 2 gallons to be drain out each day.

The equation that would best represent the relationship between the given parameters is,
y = 100 - 2x

where y is the volume of water after x days.

8. Find the congruence transformation that maps ∆ABC to ∆A’B’C’. Explain your reasoning

Answers

In this case, to flip any of the points to map up accurately to the other points, we would have to do a transformation of reflection about the y-axis. The reason behind this is that out of other transformation process, we can only achieve the image of triangle ∆A’B’C’ through reflection.

Dilation will not work since it only changes the size of the object. The shape and position will not affected.

A translation will not work because although the shape can move, it still needs to flip to achieve triangle ∆A’B’C’.

A rotation will also not work because when you rotate it, the shape will still not map over the new one.

Therefore the only answer to this question would be to reflect triangle ∆ABC about the y-axis.

Aunt Mary is 6 times as old as Jane. If Aunt Mary is 72 years old, how old is Jane?

Answers

x = Jane's age
6x =Aunt Mary's age

6x = 72
x = 72/6
x = 12 years [Jane]

Jane is 12 years old.

Because if Mary is 6 times older than just divide her age by 6. Which is 12.

And you can check like this:
-Jane is 12
-Mary is 6 times that
-so Mary is 72

A bicycle lock has a four-digit code. The possible digits, 0 through 9, cannot be repeated. What is the probability that the lock code will begin with the number 5? . What is the probability that the lock code will not contain the number 0? .

Answers

First let's find the number of the elements in the sample space, that is the total number of codes that can be produced.

The first digit is any of {0, 1, 2...,9}, that is 10 possibilities
the second digit is any of the remaining 9, after having picked one.
and so on...

so in total there are 10*9*8*7 = 5040 codes.

a. What is the probability that the lock code will begin with 5?

Lets fix the first number as 5. Then there are 9 possibilities for the second digit, 8 for the third on and 7 for the last digit.

Thus, there are 1*9*8*7=504 codes which start with 5.

so

P(first digit is five)=[tex] \frac{n(first -digit- is- 5)}{n(all-codes)}= \frac{1*9*8*7 }{10*9*8*7 }= \frac{1}{10}=0.1 [/tex]

b. What is the probability that the lock code will not contain the number 0?

from the set {0, 1, 2...., } we exclude 0, and we are left with {1, 2, ...9}

from which we can form in total 9*8*7*6 codes which do not contain 0.

P(codes without 0)=n(codes without 0)/n(all codes)=(9*8*7*6)/(10*9*8*7)=6/10=0.6

Answer:

0.1 ; 0.6

The probability that the lock code will begin with the number 5 is:

0.1

The probability that the lock code will not contain the number 0 is:

0.6

What is Probability?

This refers to the use of permutations to find the possible occurrence of events.

The total number of elements is 10

Hence, the total codes is 5040.

P(five)= n(first number)/n(all codes)= 1/10= 0.1

Next,

P(codes without zero)= n(codes without zero)/n(all codes)

(9*8*7*6)/(10*9*8*7)=6/10=0.6

=0.6

In two or more complete sentences describe how to determine the appropriate model for the set of data, (0,2), (2,3), (5,4), (10,5).

Answers

The very first thing to do in every correlation activity is to plot the gathered data points in a scatter plot. It is better to use software tools like MS Excel because they have a feature there that uses linear regression like that one shown in the picture.

Once you plot the data points, make a trendline. You are given with options. If you want a linear function, then you will have a linear model with a function equation of y = 0.2907x + 2.2643. It has a correlation coefficient of 0.9595. That's a strong correlation already. The R² value tells how good your model fits the data points. If you want to increase the R², a better model would be a quadratic function with the equation, y = -0.0209x²+0.506x+2.0232. As you can see the R² increase even more to 0.9992.

Answers

A. (x,y) - (y,-x) is the rule to rotate the figure 90 degrees clockwise.

Answer:

A. [tex](x,y)\rightarrow (y,-x)[/tex]

Step-by-step explanation:

We have been given that figure ABCD is a rectangle with point A (−2, 5). We are asked to choose the rule that would rotate the figure 90° clockwise.

We know that rule of rotating a figure 90 degrees clockwise is: [tex](x,y)\rightarrow (y,-x)[/tex]

Upon looking at our given choices we can see that option A is the correct choice.

After rotating our given point 90 degree clockwise, the coordinates of point A would be:

Find the measures of all of the angles in the parallelogram.

Answers

In a parallelogram, the opposite angles are equal so:
FED = DGF = 59x - 1
EDG = GFE = 121x + 1
And now since we know angles in a quadrilateral always add up to 360°, we can create an equation and solve for x:
2(59x - 1) + 2(121x + 1) = 360
118x - 2 + 242x + 2 = 360
360x = 360
x = 1
Now sub into our angle equations:
FED = DGF = 59(1) - 1 = 58°
EDG = GFE = 121(1) + 1 = 122°

Joey has a full 40 coins consisting of only quarters and nickels if the total value is $5.00 how many of each does joey have.

Answers

q + n = 40....q = 40 - n
0.25q + 0.05n = 5

0.25(40 - n) + 0.05n = 5
10 - 0.25n + 0.05n = 5
-0.25n + 0.05n = 5 - 10
- 0.20n = -5
n = -5 / -0.20
n = 25 <=== 25 nickels

q + n = 40
q + 25 = 40
q = 40 - 25
q = 15 <== 15 quarters

n=number of nickles
q=number of quarters

40 coins total so
n+q=40

total value is 500 cents
5n+25q=500
divide both sides by 5
n+5q=100

so we gots
n+q=40
n+5q=100

elimination
multily first equation by -1 and add to 2nd equation

-n-q=-40
n+5q=100 +
0n+4q=60

4q=60
divide both sides by 4
q=15

sub back
n+q=40
n+15=40
minus 15 both sides
n=25

25 nickles and 15 quarters

Using the given points, determine the slope.

(0, 32) and (100, 212)

Answers

Hi!

To find the slope of two given points, subtract the y values, and subtract the x values, or..

[tex] \frac{(y2 - y1)}{(x2 - x1)} [/tex]

[tex] \frac{(212 - 32)}{(100 - 0)} [/tex]

[tex] \frac{180}{100} [/tex]

The answer is 9/5 or 1.8.

Hope this helps! :)

The slope is the change in y divided by the change in x.

The slope is the ratio of rise to run.

so:

slope = (212-32) / (100-0) = 9/5 = 1.8

Answers

Check the picture attached.

let m(VTI)= m(ITU)=a and let m(VUI)= m(IUT)=b

Then, in triangle TUV:

2a+2b+c=180°

2(a+b)+c=180°

c=180°-2(a+b)

In triangle TUI:

a+b+109°=180°

a+b=180°-109°=71°

substitute in c=180°-2(a+b):

c=180°-2(a+b)=180°-2*71°=180°-142°=38°

a basketball player has already scored 56 points in a game the team record for point a in a game is 72 which equation would allow you to find out how many more points the player needs to tie the record

Answers

One equation that would work is 56+x=72 where x is the number of points the player needs.

Answer: The player needs 16 more points to tie the record.

Step-by-step explanation:

Let the number of points the player needs to tie the record be 'x'.

Number of points that a basketball player has already scored = 56

Number of points a team need for record in a game = 72

According to question, it becomes,

[tex]x+56=72\\\\x=72-56\\\\x=16[/tex]

Hence, the player needs 16 more points to tie the record.

What is the solution to this system of linear equations?

x + y = 4

x − y = 6

Answers

This is a simultaneous equation so you have to find the value of x or y. We can do this by adding the 2 equations. This would make 2x, and y + -y = nothing. 4 + 6 = 10. So we have the equation 2x = 10. Divide both sides by 2 and you get the value of x, which is 5. You then plug this into the orignal equation, either one will work. You get a value of -1 for y.
x = 5 when y = -1.

Answer:

x = 5 and y = -1

Step-by-step explanation:

[tex]x + y = 4[/tex]

[tex]x - y = 6[/tex]

To solve for x and y , we use elimination method

In the given equations, the co efficient of y are same with different coefficient

So we add both equations

[tex]x + y = 4[/tex]

[tex]x - y = 6[/tex]

--------------------------------

[tex]2x=10[/tex]

Divide both sides by 2

x= 5

now we plug in x value in first equation

[tex]5 + y = 4[/tex]

Subtract 5 on both sides

y= -1
