10. What is an expression for the perimeter of the triangle?
11. What is an expression for the area of the triangle?
12. Think about values for x, y, and z that would make the following statements true. If you think these values exist, give an
example of them. If you think they do not exist, explain why.
a.
The perimeter and area are both rational numbers.
b.
The perimeter is an irrational number and the area is a rational number.
C.
The perimeter and area are both irrational numbers.
Answers
Answer:
See explanation, and comment for more details!
Step-by-step explanation:
10. The perimeter of any shape is the sum of the length of the sides, which means that the perimeter of this triangle is x+y+z.
11. Since this is a right triangle, the two legs form the height and base. The area of this triangle is therefore x*y/2.
12.
a. x=3, y=4, z=5
b. \(x=\sqrt{2}, y=\sqrt{2}, z=2\)
c.\(x= \sqrt{3}, y=2, z=\sqrt{7}\)
Hope this helps!

ASAP: Which equation best represents the line of best fit for the data in the scatterplot above?
Answers
Answer:
F : y = -x + 4
Step-by-step explanation:
The first observation about this scatterplot is that the best line of fit will be a line going diagonally from top left to bottom right(or bottom right to top left)
Such a line has negative slope
Equation will be of the form
y = mx + b where m is a negative number
We can eliminate H and I since both lines have a positive slope which means that the line will go in a diagonal bottom left to top right direction
Let's examine options F and G
F: y = - x + 4
G: -9x + 3
Plug in some values for x from the graph and see which of the lines comes closest to the y values computed from the equations
At x = -5, the y value from the graph appears to be either 7 or 8
F: y = -x + 4 ==> -(-5) + 4 = 5 + 4 = 9; pretty close to graph's point value
G: -9x + 3 ==> -9(-5) + 3 = 45 + 3 = 48; this is greatly different from the graph value
At x = 0; the y value from graph is close to 4
From the equations we get
F: y = -x + 4 ==> y = -(0) + 4 = 4; pretty darn close
G: y -9x + 3 => y = -9 + 3 = -6; large difference
One more point
At x = 20, the point on the graph appears to be close to -19
From the equations we get
F: y = -x + 4 = -20 + 4 = -16; not too different
G: y = -9x + 3 = -9(20) + 3 = -180 + 3 = 177; way off
So the best line of fit would be
F : y = -x + 4
The equation that best represents the line of fit from the scatter plot is given as follows:
y = -x + 4.
How to define a linear function?The slope-intercept representation of a linear function is given by the equation shown as follows:
y = mx + b
The coefficients m and b have the meaning presented as follows:
m is the slope of the function, representing the increase/decrease in the output variable y when the input variable x is increased by one.b is the y-intercept of the function, representing the numeric value of the function when the input variable x has a value of 0. On a graph, it is the value of y when the graph of the function crosses or touches the y-axis.From the scatter plot, we have that when x = 0, y = 4, hence the intercept b is given as follows:
b = 4.
When x = 20, y is approximately -16, hence the slope m is obtained as follows:
-16 = 20m + 4
20m = -20
m = -1.
Hence the function is:
y = -x + 4.

Jalissa's mom purchased coffee from the local coffee shop. The first cup of coffee was $4.15. Each refill is $1.25. She also decided to get a bagel for $3.50. If Jalissa's mom had 2 refills and a $0.50 discount as part of the rewards program, how much did she spend at the coffee shop?
Answers
1.25 x 2 = 2.50
4.15 + 3.50 = 7.65
7.65 + 2.50 = 10.15
10.15 - 0.50 = 9.65
Answer:
$9.65
Step-by-step explanation:

For each ride, a taxi service charges an initial fee plus an additional fee based on the number of kilometers of the trip. The graph shows the cost for taxi rides. Select a true statement. The rise is 4 while the run is 2. The selection of answers are:
A: The slope is 2.1. This means that each kilometer costs $2.10.
B: The slope is 5. This means that each kilometer costs $5.
C: The y-intercept is 2.1. This means that the initial fee is $2.10.
D: The y-intercept is 5. This means that the ride lasts 5. kilometers.
Which one is right and why?
Answers
THIS MIGHT NOT BE WHAT YOU ARE LOOKING FOR AND MIGHT NOT BE CORRECT! READ FIRST!
The answer is A. The slope of the line is rise/run = 4/2 = 2.1. This means that each kilometer costs $2.10. The y-intercept is 2.1, which means that the initial fee is $2.10. So the correct statement is: The slope is 2.1. This means that each kilometer costs $2.10.
The other statements are incorrect. The slope is not 5, so each kilometer does not cost $5. The y-intercept is not 5, so the ride does not last 5 kilometers. The y-intercept is the value of the function when the input is 0, which in this case is the initial fee of $2.10.

In a pile of playing cards, there are six hearts, twelve clubs, and six diamonds. What is the probability that you will draw a heart?
1/2
1/6
1/4
1/3
Answers
Answer:
Step-by-step explanation:
1/4 because all equal 24 together
and so
12 is half so pulling a club would be 1/2
6 is a fourth so pulling a diamond or heart would be 1/4
because 6x2=12 so pulling a diamond or heart would be 50 - 50 from pulling a heart/diamond or a club
6=cards
2=diamonds and hearts
The probability of drawing a heart from the pile of 52 cards is 0.25.
The ratio of the number of favorable outcomes to the total number of outcomes of an event is defined as probability.
We know, the probability of an event = Number of favorable outcomes/Total number of outcomes.
As it is given that there are 6 hearts, 12 clubs, and 6 diamonds in a pile of playing cards.
Therefore, the total number of outcomes = 6+12+6= 24
and number of favorable outcomes = 6
Now, the probability of an event = 6/24
= 1/4
= 0.25
Therefore, the probability of drawing a heart is 0.25.

Hey There!
Let's solve....
Isolate for x first which is
\(x = \frac{3 + 3y}{4} \\ \)
\(substitute \: x = \frac{3 + 3y}{4} \\ \\ \brack \: 5 \times \frac{3 + 3y}{4} - 4y = 3 \\ \\ \)
Now simplify...
\( \brack \: \frac{15 - y}{4} = 3 \\ \\ = y = \frac{15 - 3}{4} \\ \\ = \frac{12}{4} \\ simplify \\ \\ \frac{ \cancel{12} ^{3} }{ \cancel{4}^{1} } \\ x = 3\)
Y=3
We need to find value of y first... now x
\(x = \frac{3 + 3 \times 3}{4} \\ \\ =x = \frac{3 + 9}{4} \\ \\ = x = \frac{12}{4} \\ simplify \: \frac{ \cancel{12}^{3} }{ \cancel{4} ^{1} } \\ \\ value \: of \: x = 3 \)

x = -1.3
I hope this is right, and I am sorry if this is wrong if it is! I rlly hope this helps you out and you can understand my method and the way I typed this!!
Step-by-step explanation:
We are going to use one of my fav methods! The substitution method!
Set this aside for now: 4x - 3y = 3 We gonna use this one: 5x - 4y = 3
5x - 4y = 3
= 5x - 3 = 4y
( also, the subtraction is with the 4y as a negative, so 4y would be positive if you moved it!)
Divide all of the equation by 4!
y = \(y = \frac{5x - 3}{4}\)
Now, you take take the other equation and substitute the y with what you have above!
\(4x - 3 times \frac{5x - 3}{4} = 3\)
you cross multiply 4( the denominator) with the other side that has only a three!
4x - 3 \(times 5x - 3\) = 12
4x - 15x - 3 = 12
-11x - 3= 12
Move the three to the other side become positive!
-11x = 15
divide both sides by -11
x = -1.3
Container A has 800 ml of water and is leaking 6 ml per minute.

Let m represest the number of minutes the contains are leaking.
How many minutes, m, will it take for the two containers to have the same amount of water?
Answers
It will take 50 minutes for the two containers to have the same amount of water.
Based on the information given, the equation to solve the question will be:
800 - 6m = 1000 - 10m
Collect like terms
-6m + 10m = 1000 - 800
4m = 200
Divide both side by 4
4m/4 = 200/4
m = 50
Therefore, it'll take 50 minutes.
