Determine which sides correspond with each angle in triangle ABC below
Answer:
1. b 2.a 3c
Step-by-step explanation:
The sides that correspond to each angle in triangle ABC are:
Angle XYZ corresponds with side length YZ
Angle ZXY corresponds with side length XZ
Angle YZX corresponds with side length YX
What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Since, We know that;
The corresponding sides are segments located at the same relative position of an angle.
So, the corresponding sides of the angles are:
Side YZ & angle XYZ,
Side XZ & angle ZXY,
And, Side YX and angle YZX
Thus, The sides that correspond to each angle in triangle ABC are:
Angle XYZ corresponds with side length YZ
Angle ZXY corresponds with side length XZ
Angle YZX corresponds with side length YX

(08.03)A group of 22 students participated in a race. Their scores are below:
Score (points)

6–7
8–9
10–11
12–13
Number of Students
3

Would a dot plot or a histogram best represent the data presented here? Why?
-------------------------
Here are the answer choices:
A: Dot plot, because a large number of scores are reported as ranges
B: Dot plot, because a small number of scores are reported individually
C: Histogram, because a large number of scores are reported as ranges
D: Histogram, because a small number of scores are reported individually
Answer:
A dot plot generally shows the data for a specific value, it is just like how you would need each individual's score. A histogram shows data for a range of values. The best one to use here is a histogram.
Step-by-step explanation:
Answer: The answer is C
Step-by-step explanation: Histograms show ranges and the table shows ranges and scores. A dot plot would not fi this situation as well as histograms because histograms are best when it comes to ranges.

Step-by-step explanation:
y = [tex]\frac{1}{5}x + 2[/tex]
Find two points
When x = 0 , y = 0 + 2 = 2
D(0 , 2)
When x = 5;
[tex]y=\frac{1}{5}*5+2= 1 + 2 = 3[/tex]
E(5, 3)
Plot (0, 2 ) and (5 , 3) in the graph and join the points. This will be the line for the equation y =(1/5)x + 2
y = -x + 8
When x =4 , y = -4 + 8 = 4
A(4 , 4)
When x = 6 ; y = -6 + 8 = 2
B(6 , 2)
Plot (4,4) and (6, 2) in the graph and join the points. This will be the line for the equation y = - x + 8.
This lines will intersect at point (5,3) and that point will be the solution of the equation.

Answer:
Quadratic function, None of the above, and ?
Step-by-step explanation:
So remember what I told you about earlier, lets look at that first one.
So we can see that x is increasing by 1 and y is decreasing by 3...And then it increases by 3! And after that another 9! Well, that seems like it is reversing, as it changes from decreasing to increasing in y coordinates. So knowing that is reverses from decreasing to increasing in y, it must be a quadratic function!
Next we have a increase in 1 and a decrease by 17...then 12...then 7 in y. This isnt decreasing by a constant amount like a linear function. It doesnt seem like a obvious exponential decrease either, and it isnt reversing like a quadratic function does. I am going to use something called logarthms, which you don't even need to think about yet, just to make sure that it is not an exponent. Althouhg the difference in the exponent was only 0.0018, it is a differnece. So this must be a none of the above, sicne none of the functions apply. (If this is incorrect, and it is exponential, then the test is wrong. While the method I used is something found in mid algebra 2, it is still a method of finding a exponent of a number.)
Now we finish up with a change in x of 1, and a change of y by...-11, -11, -11!
Well, what do you think this is, thinking back on what I have said so far.
It is a constant change of -11y and 1x. Remember, a CONSTANT CHANGE.
What do you think it is :)

Consider g(x) = 3x − 3. What is an equation for each graph in terms of g?
7. y-intercept is 0
8. y-intercept is 8
9. y-intercept is −3
Answer:
Refer to explanation!
Step-by-step explanation:
g(x)=3x-3 can be rewritten as g(0) = 3(0) - 3, which makes g(0) = -3. This also makes the y-intercept = to -3.

The graph shows the distance, in miles, that Anders traveled over a period of nine hours.
Use the graph to determine the constant of proportionality between the number of miles traveled and the number of hours traveled.
A. 60
B. 65
C. 130
D. 585
Answer: B. 65
Step-by-step explanation:
Choose any point on the number line with natural numbers for both coordinates. For this case, let's use (4, 260).
To find the constant of proportionality, divide the Y coordinate by the X coordinate. 260 ÷ 4 = 65. While optional, it is reccomended to use two points to confirm your answer. Let's do that with (2, 130). Since 130 ÷ 2 = 65, this confirms that the constant of proportionality is 65.

y = x + 2.5
Step-by-step explanation:
slope = (y2-y1)/(x2-x1) where the variables indicate the coordinates of the two points
slope = (2.5-1.5)/(0+1) = 1
equation = y-y1 = m(x-x1)
y - 2.5 = x
y = x + 2.5

Mimi uses a 7.5-gal bucket to fill a wading pool. She pours 12 buckets full of water into the pool, which can hold up to 138 gal of water. She wants to solve for n, the number of additional full buckets of water she can pour into the pool.
Answer: 6 full buckets.
Step-by-step explanation:
138(pool)/7.5(a bucket)=18.4
18-12=6 full buckets.
Ms. Steven creates a drawing in her kitchen. Her drawing is 7cm in length and 4cm in width. The scale on the drawing is 1cm = 3ft. What is the actual area of the kitchen in square ft?
Answer:
7cm=7×3ft=21ft
4cm=4×3ft=12ft
here
length=21ft
breadth=12ft
now
area= l×b
=21ft×12ft
=252ft^2
Answer: 252 ft²
Step-by-step explanation:
The drawing's dimensions are given to be 7 cm in length, and 4 cm in width. Those values are multiplied by 3 to get the scaled drawing. This gives us 21 feet and 12 feet. When you multiply 21 feet by 12 feet, you get 252 ft². DO NOT FORGET to put the ² in the final answer.
