Right triangle ABC is transformed into right triangle A'B'C what is the scale factor of dilation
Answers
Answer:
D. 3
Step-by-step explanation:
The scale factor used to transform right triangle ABC into right triangle A'B'C' is the ratio of any corresponding side length of ∆A'B'C' and ∆ABC.
Thus, using the ratio of side length A'B' to side length A'B', we can get the scale factor as follows:
A'B' = 12 - 6 = 6 units
AB = 4 - 2 = 2 units
Scale factor = A'B' : AB = 6 : 2 = 6/2 = 3

Solve for x and/or y:
Answers
Answer:
C) x=35
Step-by-step explanation:
First, we know that the total amount of degrees in a rotation is 360. As the picture tells us, the opposite angles will be exactly the same. Taking this information, we can have the following equation:
4x + 2(3x+5) = 360
By now using our linear equation skills, we get:
10x+10=360
10x=350
x=35
The degree amount of x for c) is 35 degrees.
C. Since the angles form a linear pair, their sum equals 180.
So, 2x + 3x + 5 = 180
x=35
D. Since the angles are verticle, they equal each other.
So, 3x + 5 = 5x -57
x=31

I have also used an online algebra calculator to check my answer so this is correct.
Two cyclists are 7 miles apart when they begin biking away from each other in opposite directions. The speed of the first cyclist is 12 miles per hour. The speed of the second cyclist is b miles per hour greater than the speed of the first cyclist.
How many miles does the second cyclist bike in 45 minutes?
Answers
Answer:
The distance covered by the second cyclist in 45 minutes is (3/4·b + 9) miles
Step-by-step explanation:
The given parameters are;
The distance between the two cyclist when they begin biking away from each other = 7 miles
The first cyclist's speed = 12 miles per hour
The second cyclist's speed = 12 + b miles per hour
Therefore, we have;
The equation for distance covered, d = Speed × Time
The distance covered by the second cyclist in 45 minutes, [tex]d_{45 \ minutes}[/tex] is given as follows;
45 minutes = 3/4 hour
[tex]d_{45 \ minutes}[/tex] = (12 + b) × 3/4 = (3/4·b + 9) miles
The distance covered by the second cyclist in 45 minutes = (3/4·b + 9) miles.
Answer:
The distance covered by the second cyclist in 45 minutes is (3/4·b + 9) miles
Step-by-step explanation:
The given parameters are;The distance between the two cyclist when they begin biking away from each other = 7 milesThe first cyclist's speed = 12 miles per hourThe second cyclist's speed = 12 + b miles per hourTherefore, we have;The equation for distance covered, d = Speed × TimeThe distance covered by the second cyclist in 45 minutes, is given as follows;45 minutes = 3/4 hour = (12 + b) × 3/4 = (3/4·b + 9) milesThe distance covered by the second cyclist in 45 minutes = (3/4·b + 9) miles.

He used a graphing tool to display the data in a scatter plot, with x representing the minutes spent memorizing the poem and y representing the number of errors. Then he used the tool to find the equation of the line of best fit:
y = -0.118x + 14.327.

Geometry Writing Prompt 2
Directions: Determine what reason is missing from the proof. Write one paragraph explaining how you know that’s the correct reason. See the grading rubric for all requirements for writing a paragraph.
Option 1:
Answers
The missing reason is AAS Congruence Theorem
You can simply say AAS for short, and your teacher will likely know what you mean.
The AAS stands for Angle Angle Side. It refers to the fact how we can use two pairs of congruent angles, and a side that is not between the angles, to prove two triangles are congruent.
In this case, ABE = CDE are the two congruent 90 degree angles, and AEB = DEC are the two vertical angles
The two congruent sides are shown by the tickmarks, so AB = CD. In other words, this information is given.
Keep in mind that AAS is slightly different from ASA, so the order matters.
A public swimming pool that holds 45,000 gallons of water is going to be drained for maintenance at a rate of 100 gallons per minute. The amount of water, w (in gallons), in the pool after t minutes is given by the function w = 45,000 – 100t. How many minutes will it take to empty the pool?
Answers
Answer:
450 minutes
Step-by-step explanation:
Given
w = 45000 - 100t
Required
Determine how long it'll take to empty the pool
Being empty means there's no water in the pool.
So, we have to set w to 0 to get the value of t
i.e w = 0
Substitute 0 for w in w = 45000 - 100t
0 = 45000 - 100t
Collect Like Terms
100t = 45000
Divide through by 100.
t = 450
Hence, it'll take 450 minutes to empty the pool
