What is scale factor?Scale factor is the factor which is used to enlarge or smaller the original figure.
Scale factor is the ratio of representation measurement of the figure to the original figures.
On a blueprint, an architect drew a 12-inch line to represent the length of a 30-foot room. Thus, the scale factor of foot to inch is,
[tex]k=\dfrac{30}{12}[/tex]
Let suppose the line that represents the width of the room is 8 inches long, has the size of room in foot is x. Thus,
[tex]k=\dfrac{8}{x}\\\dfrac{12}{30}=\dfrac{8}{x}\\x=\dfrac{30\times8}{12}\\x=20[/tex]

Step-by-step explanation:
Answer: The equation 60 + x= 3x -70 could be set up to solve for x.
Step-by-step explanation:
The two remote interior angles sums will equal to the exterior angle .
Meaning that angle 60 plus angle x has to equal to angle 3x -70.
60 + x= 3x -70 Now solve for x by adding 70 to both sides
+70 +70
130 + x = 3x Now subtract x from both sides

84%, 71%, 64%, 90%, 75%, 44%, 98%
Which measure of center should Peter choose so he can have the highest percentage possible?
O Peter should choose the mean after dropping one test score.
Peter should choose the mean without dropping one test score.
O Peter should choose the median after dropping one test score.
O Peter should choose the median without dropping one test score.
Answers
t would be best if Peter's report card percentage was based on the mean and if he could drop a percent, he should drop the 44%.
Step-by-step explanation:
The median (without dropping a score) of this set would be 75%
( 44%, 64%, 71%, 75%, 84%, 90%, 98% )
The mean (without dropping a score) of this set would be 75.1428571%
526 ÷ 7 = 75.14 ( 75.1428571 )

Devaughn is 13 years younger than Sydney. The sum of their ages is 79 . What is Sydney's age?
Answers
Answer: 46 years old
Step-by-step explanation: If Devaughn is 13 years younger than Sydney,
we can represent Sydney's age as x and Devaughn's age as x - 13.
Since the sum of their ages is 79, we have x + x - 13 = 79.
This simplifies to 2x = 92.
Dividing both sides by 2, we have x = 46.
So sydney is 46 years old.

1. Which equation represents a line that passes through the point (-2,6) and is parallel to the line whose equation is 8x – 4y = 6?
Answers
Answer:
y=2x+10
Step-by-step explanation:
First, let's put the equation into slope-intercept form. We get y=2x-3/2.
Parallel lines have the same slope, so the slope of the line will be 2.
We then substitute the point into the equation to find the y-intercept.
We get y=2x+10
