Answer:
True , because all properties preserved under dilation from triangle abc to a'b'c'.
Step-by-step explanation:
Given : A triangle abc is dilated by a factor of 2/3 , result triangle a'b'c'
To find :After dilation, properties of triangle abc and a'b'c' is true or false.
Solution:
Dilation of a triangle are result either decrease or increase the corresponding length of triangle , its depends on by which scale factor triangle is dilated ,and dilation does not affect the angle measures of triangle.here scale factor is 2/3 so corresponding sides of triangle a'b'c' decreases.
So, dilation of triangle are not congruent but similar to the original triangle abc
Therefore , basic properties of triangle preserved under dilation of triangle by a scale factor.

line a passes through points (5,8) and (10,6). line b is perpendicular to a. what is the slope of line b?
Answer:
2/5
Step-by-step explanation:
First, we need to find the slope of line a. To do this, we subtract the two y values and then the two x values and divide these two differences.
10-5=5
6-8=-2
5/-2= -5/2
A perpendicular line's slope will always be equal to the negative reciprocal of the intersects. So, we just flip the numerator and denominator and then add a negative to our first slope to get the slope of line b.
-2/5
--2/5
2/5

Write an expression for the slope of the line in the graph using the letters u,v,s, and t.
Answer:
We conclude that the slope between (s, t) and (u, v):
slope = [v - t] / [u - s]Step-by-step explanation:
We can find the slope between two points (x₁, y₁) and (x₂, y₂) using the formula
slope = [y₂ - y₁] / [x₂ - x₁]
In our case, the two points are
(x₁, y₁) = (s, t)
(x₂, y₂) = (u, v)
Thus, the slope between (s, t) and (u, v)
slope = [v - t] / [u - s]
Therefore, we conclude that the slope between (s, t) and (u, v):
slope = [v - t] / [u - s]A company prints 4580 copies of the same book. The number of pages in the book, including the cover pages, is 79. What is the total number of pages, including the cover pages, that the company prints?
Answer: 361,820 pages
Step-by-step explanation:
The company prints 4,580 copies of the same book and it has 79 pages including cover pages.
The total number of pages the company prints therefore is:
= 4,580 * 79
= 361,820 pages

A student measures the length of her dress to be 60 inches long but the actual length of her dress is 65 inches long. What is the percent error of this student
Answer:
8.333% error
Step-by-step explanation:
using percent error formula
(actual - expected) / expected * 100 %
actual = 65
expected = 60
plug
(65-60)/60 * 100%
= 8.33 %
Explain the importance of putting your data set in order from least to greatest
Answer:
The mean may not be a fair representation of the date
Step-by-step explain the average is easily influenced by outliers (very small or large values in the data set that are not typical). The median is another way to measure the center of a numerical data set. ... Thus, the median is truly the middle of the data set.

If Mr. Jones buys paddles for $35 instead of $50 and uses the same percent increase on price how many paddles most Mr. Jones sell for the total paddle sales before tax and to be at least $250 explain your answer
Answer: 4 paddles
Step-by-step explanation:
Mr. Jones buys the paddle for $35 and sells at 180% of the purchase price:
= 35 * 180/100
= $63
For the number of paddle sales to be at least $250, he should sell:
= 250/63
= 3.97
= 4 paddles
Michael has 3 quarters, 2 dimes, and 3 nickels in his
pocket. He randomly draws two coins from his pocket,
one at a time, and they are both dimes. He says the
probability of that occurring is because 2 of the 8
coins are dimes. Is he correct? Explain.
My Answer:
The events are dependent.
The size of the original sample space is 8. It changes to 7 after the first dime is chosen.
The probability of picking the first dime is 2/8.
The probability of picking the second dime is 1/7
To find the probability of the compound event, multiply the probabilities.
I got it correct, on edge 2020/2021
Answer:
No. Choosing two dimes are dependent events. The probability of choosing the first dime is 14 and the probability of choosing the second dime is 17 . The probability that both coins are dimes is (14)(17) = 128.

Answer:
a)
(i) 43, 56
(ii) -1,3
b)-27
c) -21 +4n
Step-by-step explanation:
For a,i, you can see that it decreses by 7 each time so you subtract 7 from 50 to get 43, then you subtract 7 from that to get 56. For a,ii it increases by 4 each time so you add 4 to -5 to get -1, then add 4 to that to get 3. For b, because it is the 15th term you are looking for, you can plug 15 into the equation as n so 78-7n to 78- 7*15, 78-105, -27. For c, you know that each time it increases by 4, so you know you add 4n, and then for the base, you have to find the term before -17 so you subtract 4 to get -21. Put it together and get -21+4n.

How do I fine x to the nearest tenth ??
Answer:
x = 13.6
Step-by-step explanation:
Here, we want to find the value of x
to find the value of x. we are going to use the sine rule
It states that the ratio of the sine of an angle to the measure of the side facing the angle is fixed for a triangle
In this case;
11/ sin 27 = x/ sin 34
x = 11 sin 34/sin 27
x = 13.6

The values of m and n are whole numbers greater than 1. Which is true about the quotient
Answer:
"The expression will always equal m" is true about the quotient of [tex]\frac{m}{n}[/tex] ÷ [tex]\frac{1}{n}[/tex]
Step-by-step explanation:
Let us solve the question
∵ The expression is [tex]\frac{m}{n}[/tex] ÷ [tex]\frac{1}{n}[/tex]
→ In the division of fractions, we change the division to multiplication
and reciprocal the fraction after the division sign
∵ The reciprocal of [tex]\frac{1}{n}[/tex] is [tex]\frac{n}{1}[/tex]
∴ [tex]\frac{m}{n}[/tex] ÷ [tex]\frac{1}{n}[/tex] = [tex]\frac{m}{n}[/tex] × [tex]\frac{n}{1}[/tex]
→ In the multiplication of fractions, we can simplify the terms in
the numerators by the terms in the denominators
∵ There is n in the numerator and denominator
∴ Cancel n up and down
∴ [tex]\frac{m}{n}[/tex] × [tex]\frac{n}{1}[/tex] = [tex]\frac{m}{1}[/tex]
∴ [tex]\frac{m}{n}[/tex] × [tex]\frac{n}{1}[/tex] = m
∴ [tex]\frac{m}{n}[/tex] ÷ [tex]\frac{1}{n}[/tex] = m
∴ The quotient is m
∴ The expression will always equal m
