Answer:
its B
Step-by-step explanation:
because if you flip e to the other side of the y-axis you'll get (2,4) and do the same with the letters and that's your answer.
Answer:
B. C'(3 , 0) , D'(7 , 1) , E'(2 , 4)
Step-by-step explanation:
reflecting the point A(x , y) across the y-axis gives us the point A'(-x , y)
Then
The image of E(-2 , 4) is E'(2 , 4)
The image of C(-3 , 0) is C'(3 , 0)
The image of D(-7 , 1) is D'(7 , 1)
Therefore
The correct answer is option B.

Given: a||b and c||d, m∠4=35°
Find: m∠1, m∠2, and m∠3
The measure of the angles m∠1, m∠2 and m∠3 are 145°, 35° and 35° respectively.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
m∠2 = m∠4 = 35° (corresponding angles are equal)
m∠2 = m∠3 = 35° (corresponding angles are equal)
m∠1 + m∠3 = 180° (base angles are supplementary)
m∠1 + 35 = 180
m∠1 = 145°
The measure of the angles m∠1, m∠2 and m∠3 are 145°, 35° and 35° respectively.

Christina wants to buy some miniature goldfish. She reads that a 9-gallon aquarium is the
right size for 3 miniature goldfish. The graph represents this relationship.
Answer:what graph?
Step-by-step explanation:
if we cant see the graph then we cant answer lol
Based on the image attached of the graph, the points that show equivalent ratios that would also be on the graph are option A and D which are: (6,18) (1,3).
What is the graph about?Note that: [tex]\frac{x}{y}[/tex]
=[tex]\frac{3}{9}[/tex]
= 1/3
So when you use 1/3 to compare all the options given, you will see that only option A and D is equal to the value given.
So if a person can write that we got 1 fish and we needs 3 gallons and when a person make a point on the line, it will be (1,3).
The other equivalent fraction is known to be 6/18. When a person multiply the numerator and denominator by 2, the value that will be obtained is:
[tex]\frac{3 x 2 }{9 x 2}[/tex] = 6/18.
So therefore, Based on the image attached of the graph, the points that show equivalent ratios that would also be on the graph are option A and D which are: (6,18) (1,3).

18. Curry powder is sold at $7.45 per 100 g. How much money will Thuy need in order to buy 3 kg of curry powder?
Answer:
Step-by-step explanation:
$7.45 = 100g
x = 3kg( 3 × 1000) = 3000g
∵ $7.45 = 100g
x = 3000g
(100 × x) = (7.45 × 3000)
100x = 22350
100x/100 = 22350/100
x = $223.5

V= 308 35/64
Answer:
explanation will answer.
Step-by-step explanation:
To convert this fraction to a decimal, just divide the numerator (35) by the denominator (64). So, 35 / 64 = 35 ÷ 64 = 0.546875. Approximated Values: 35 / 64 = 0.5 rounded to 1 significant figure. 35 / 64 = 0.55 rounded to 2 significant figures. 35 / 64 = 0.547 rounded to 3 significant figures.

7.30. Julie wants to give a 45 -minute speech, and she speaks 120 words per minute. Her written notes contain 500 words per page. How many pages should she prepare?
Answer:
10.8 pages must be prepared
Step-by-step explanation:
We first have to figure out how many words Julie would be able to say in 45 minutes. Since she can say 120 words per minute, she can speak 120*45 or 5400 words total.
We also know that Julie can write 500 words per page. Since she has 5400 words total, she needs to prepare 10.8 pages total (5400 divided by 500). If you are looking for a whole number answer, Julie needs at least 11 pages to write her complete speech.
Answer:
The number of pages she should prepare is 10.8 pages.

PLEASE HELP ME AND REMEMBER TO SHOW ALL WORK, IT'S DUE TODAY!!!
TYSM
Answer:
84°
Step-by-step explanation:
The circle has five central angles that together equal to 360°.
55° + 37° + 96° + 88° = 276°
Hence, to find the fifth central angle, we have to subtract 276° from 360°.
360° - 276° = 84°
The degree measure of the last central angle is 84°.

8. MAGAZINES You want to compare the number of words per sentence in a sports magazine to the number of words per sentence in a political magazine.
a. The data represent random samples of 10 sentences in each magazine. Compare the samples using measures of center and variation. Can you use this to make a valid comparison about the magazines? Explain.
Sports magazine: 9, 21, 15, 14, 25, 26, 9, 19, 22, 30 Political magazine: 31, 22, 17, 5, 23, 15, 10, 20, 20, 17
Answer:
I also don't know so I am sorry I need point
Answer:
On comparing the center i.e. mean we get that the sports magazine 19 uses more words than a political magazine 18 but they are almost the same because their difference is only 1. The variance of sports magazines 5.8 is greater than the variance of political magazines 5.2. We cannot use this to make a valid comparison about the magazines to a magazine the content matters or maybe the number of readers matters not the number of word count.
Step-by-step explanation:
Given: The number of words per sentence in a sports magazine to the number of words per sentence in a political magazine. The data represent random samples of 10 sentences in each magazine.
Sports magazine [tex]$$9,21,15,14,25,26,9,19,22,30$$[/tex].
Political magazine [tex]$$31,22,17,5,23,15,10,20,20,17$$[/tex].
To compare the samples using measures of center and variation.
Find the mean of both the data and compare them.Find the variance of both the data and compare them.Step 1 of 2
The mean of the words of sports magazine is [tex]\begin{aligned}(9+21+15+14+25+&26+9+19+22+30) \times \frac{1}{10} \\&=\frac{190}{10} \\&=19\end{aligned}[/tex]
The mean of the words of the political magazine is [tex]\begin{aligned}&(31+22+17+5+23+15+10+20+20+17) \times \frac{1}{10}\\&=\frac{180}{10}\\&=18\end{aligned}[/tex]
On comparing the center i.e. mean we get that the sports magazine uses more words than a political magazine.
Step 2 of 2
Variation of sports magazine is [tex]=\frac{1}{10}\times(|19-9|+|19-21|+|19-15|+|19-14|+|19-25|+|19-26|+|19-9|+|19-19|+|19-22|+|19-30|)$$\\ $$=\frac{1}{10}\times(10+2+4+5+6+7+10+0+3+11)$$\\$$=\frac{1}{10}\times58$$\\$$=5.8$$[/tex]Variation of the political magazine is \end{tabular}
[tex]=\frac{1}{10}\times(|18-31|+|18-22|+|18-17|+|18-5|+|18-23|+|18-15|+|18-10|+|18-20|+|18-20|+|18-17|)$$\\ $$=\frac{1}{10}\times(13+4+1+13+5+3+8+2+2+1)$$\\ $$=\frac{52}{10}$$\\ $$=5.2$$[/tex]
The variance of sports magazines is greater than the variance of political magazines.
We cannot use this to make a valid comparison about the magazines to a magazine the content matters or maybe the number of readers matters not the number of word count.
