Consider the enlargement of the triangle and use the measurements to calculate the scale factor. 2 triangles have corresponding side lengths of 8 centimeters and 64 centimeters. Scale factor =.
The scale factor is the ratio of the second triangle length to the first triangle length. Then the scale factor is 8.
What is dilation?Dilation means the changing of the size of the object without changing the shape. The size of the object may be increased or decreased based on the scale factor.
Two triangles have corresponding side lengths of 8 centimeters and 64 centimeters.
Then the scale factor will be
[tex]\rm Scale \ factor = \dfrac{Side \ of \ second \ triangle }{Side \ of \ first \ triangle } \\\\\\Scale \ factor = \dfrac{64}{8}\\\\\\Scale \ factor = 8[/tex]
The scale factor is 8.

question 6 Which set of coordinates does NOT represent a function?
Answer:
The first one
Step-by-step explanation:
You can't repeat coords on the x or y coordinate, meaning that the one to the left is wrong because it is the only one that repeats
Answer:
First table
Step-by-step explanation:
How do you figure out if a relation is a function? You could set up the relation as a table of ordered pairs. Then, test to see if each element in the domain(x) is matched with exactly one element in the range(y). If so, you have a function!
Let's try it on the first table; Lucky us! we found it! the value 1 and 2 repeat more than once connecting with with two DIFFERENT y values!

8 cupcakes cost $32. What is the unit cost per cupcake?
============================================================
Explanation:
The "per cupcake" means "for each cupcake" or "for 1 cupcake".
To get that initial "8 cupcakes" into "1 cupcake", we divide both given values by 8
8/8 = 132/8 = 4The ratio 8 cupcakes : $32 then becomes 1 cupcake : 4 dollars
In other words, the unit cost is 4 dollars per cupcake.

Answer:
x = 145 degrees
Step-by-step explanation:
In leftmost triangle, missing angle :
= 180 - (90 + 35)
= 55 degrees
Top angle of middle triangle :
= 180 - (60 + 55)
= 180 - 115
= 65 degrees
Bottom angle of middle triangle :
= 180 - (90 + 65)
= 25 degrees
Linear pair
= 180 - 25
=> x = 145 degrees

Answer:
Factored form: (x+4)(x+5) = 0
x = -5 or -4
Step-by-step explanation:
To factor x^2 + 9x + 20, we need to find 2 numbers that multiply to 20 and add up to 9.
The reason for that is because when you multiply (x+a)(x+b) using FOIL, you will get x^2 + ax + bx + ab.
Anyway, 4 and 5 would satisfy this, because 4+5 = 9 and 4*5 = 20. We can then factor the equation to (x+4)(x+5).
To solve (x+4)(x+5) = 0, we need to make either x+4 = 0 or x+5 = 0. That means x can be either -5 or -4.

What is the approximate area of the shaded region under the standard normal curve below? Use the portion of the standard normal table given to help answer the question. A normal curve with a peak at 0 is shown. The area under the curve shaded is negative 2 to negative 1. Z Probability 0. 00 0. 5000 1. 00 0. 8413 2. 00 0. 9772 3. 00 0. 9987 0. 02 0. 14 0. 34 0. 84.
The area under the shaded region from 1 to 2 is 0.14
What will be the shaded region area?Probabilities actually define the percentage of the happening of an event
Here the shaded region shows the probability of the z-scores
The shaded region 1 to 2 is represented as:
[tex]P(1 < z < 2)[/tex]
By using the probability of z-score we can have
[tex]P(1 < z < 2)=P(z < 2)-P(z < 1)[/tex]
From the given standard normal table:
[tex]P(z < 2)=0.9772[/tex]
[tex]P(z < 1)=0.8413[/tex]
So, we have:
[tex]P(1 < z < 2)=0.9772-0.8413[/tex]
[tex]P(1 < z < 2)=0.1359[/tex]
The approximated value will be
[tex]P(1 < z < 2)=0.14[/tex]
Thus the area under the curve shaded is 1 to 2 is 0.14

, when substituted for the variable, makes the equation 5 x − 3 = 7 true?
Answer:
x should equal 2
Step-by-step explanation:
5x2=10
10-3=7
How can you know if this equation is true? 12+38=410=25 1 2 + 3 8 = 4 10 = 2 5 CLEAR CHECK Because 1+3=4 1 + 3 = 4 and 2+8=10 2 + 8 = 10 , this equation must be true. Because 25<12 2 5 < 1 2 , this equation can not be true. This equation must be true, because when you add fractions the sum is always less than 12 1 2 . Because 38<12 3 8 < 1 2 , this equation must be true.
Given:
The equation is
[tex]\dfrac{1}{2}+\dfrac{3}{8}=\dfrac{4}{10}=\dfrac{2}{5}[/tex]
To find:
Whether the given equation is true or not.
Solution:
In addition of two fractions, we can not add numerator and denominator separately. First we need a common denominator, then we add numerators.
We have,
[tex]\dfrac{1}{2}+\dfrac{3}{8}[/tex]
Taking LCM, we get
[tex]\dfrac{1}{2}+\dfrac{3}{8}=\dfrac{1\times 4+3}{8}[/tex]
[tex]\dfrac{1}{2}+\dfrac{3}{8}=\dfrac{4+3}{8}[/tex]
[tex]\dfrac{1}{2}+\dfrac{3}{8}=\dfrac{7}{8}\neq \dfrac{4}{10}[/tex]
So, the given equation is not true.
Therefore, the correct option is B.

Step-by-step explanation:
The given information are;
The of the object = 180°
Therefore, a line drawn though the a point on the preimage passing through the center of rotation
A second line is drawn from the center of rotation, towards the direction of the expected location of the image of the chosen point on the preimage which should in this case be 180° and the distance from the location of the point on the image to the given center of rotation should be the same as the distance of the point of the preimage from the given center of rotation.

Elaine is in London for one day only. She only has time to see two shows of the three shows she likes. The shows are Hamilton, Aladdin and Thriller. She makes her choice of the two shows at random. What is the probability that she sees Aladdin and Thriller?
Answer:
[tex]\frac 13[/tex]
Step-by-step explanation:
All three shows she likes are Hamilton, Aladdin, and Thriller.
But she can watch only two shows among the three shown.
The possible combination of the shows she can watch are
(Hamilton and Aladdin), (Aladdin and Thriller) and (Hamilton and Thriller).
So, the total number of possible events (available options)= 3.
As we have to determine the probability of watching Aladdin and Thriller, so here Aladdin and Thriller is the favorable event.
So, the number of favorable event=1
Now,
[tex]\text{Probability}=\frac{\text{Total number of possible events}}{\text{Total number of favorable events}}[/tex]
[tex]=\frac{1}{3}[/tex]
Hence, the probability that she sees Aladdin and Thriller is [tex]\frac 1 3[/tex].
