Answer:
B
Step-by-step explanation:
34 x 1/2 = 17 (Line A'B')
28 x 1/2 = 14 (Angle A')
The length of A'B' and measure of angle A after the dilation are respectively: 15 & 28°.
What is the similarity of triangles?Triangles with the same shape but different sizes are said to be similar triangles. Squares with any side length and all equilateral triangles are examples of related objects. In other words, if two triangles are similar, their corresponding sides are proportionately equal and their corresponding angles are congruent. Triangle resemblance is shown here by the symbol "≈"
By Pythagoras theorem we can check, the given sides do not form a right angle triangle.
Now, let's apply the dilation to the given triangle ABC.
Since the dilation factor is 1/2, the length of each side of A'B'C' will be half of the corresponding side of ABC.
So, the length of AB is 30 and the length of A'B' is 1/2 of AB, which is 15.
To find the measure of angle A', we need to use the fact that corresponding angles in similar triangles are congruent. S
ince ABC and A'B'C' are similar triangles, angle A is corresponding to angle A'. We know that angle A is 28 degrees, so angle A' must also be 28 degrees.
Therefore, the answer is D. A'B' is 15 and mZA' is 28°.

8^2 + b^2 = 10^2, and b = 6
Step-by-step explanation:
This is a right triangle, so use the Pythagorean theorem
a^2 + b^2 = c^2, where 8 is a, b is b, and 10 is c
8^2 + b^2 = 10^2
64 + b^2 = 100
100 - 64 = 36
b^2 = 36
b = 6

A total of 640 tickets were sold for the school play. They were either adult tickets or student tickets. There were 60 fewer student tickets sold than adult tickets. How many adult tickets were sold?
NO LINKS
Answers
Answer:
350 adult tickets were sold
Step-by-step explanation:
Let x represent the number of adult tickets sold.
Since there were 60 fewer student tickets sold than adult tickets, the number of student tickets sold can be represented by x - 60
Create an equation that sets up these terms equal to 640, then solve for x:
(x) + (x - 60) = 640
2x - 60 = 640
2x = 700
x = 350
So, 350 adult tickets were sold

Answer:
1: 3/3 of 4 is equal to four because 3/3 is a whole.
2: 2/3 of 4 is less than 4 because 4 represents a whole number, and 2/3 is not whole.
3: 4/3 of 4 is greater than 4 because 4/3 is bigger than a whole.
Step-by-step explanation:
3/3, 2/2, and 4/4 could all be equal to 4 because they all represent a whole, since the number 4 is a whole.
2/3 and 1/2 both are parts of a whole. 1/2 of 4 would be 2. Since they all represent "parts" of a whole. (4)
4/3 is greater than 4 because the top number is bigger than the bottom number. In order for 4/3 to be equal to 4, both numbers would need to be the same, regardless of what numbers they are. Hope this helped! Have a great day/night! Please give brainliest so I can get to the virtuoso rank!

9. B 10. C 11. A 12. C
Step-by-step explanation:
Greater rate of change simply means slope! Which ever of the functions has the greatest slope (positive or negative)
9.
a. The graph shows the line going up by 4, and across by 3, or, a slope of 4/3
b. the table is increasing by 10, so, 10/1
c. -6 = -6/1, out of all of these, we divide by the denominators and determine which number is the greatest, ignoring whether or not the value is positive or negative
a. 4/3 = 1.333333
b. 10/1 = 10
c. -6/1 = -6 (remember, ignore the sign)
In this case, B is the greatest number, therefore, it has the greatest rate of change
10.
a. -3 / 3 = -1 (ignore the negative!)
b. 2/1 = 2
c. 4/1 = 4
In this case, C, is the greatest number, meaning its rate of change is highest
11.
a. -1/3 = -0.333333 (ignore the yk what!)
b. 0.25/1 = 0.25
c. -1/5 = -0.20 (you already know)
In this case, a, is the greatest number, meaning, its rate of change is the highest
12.
a. 0/1 = 0
b. 0.5/1 = 0.5
c. 2/1 = 2
In this case, c, is the greatest number, meaning, its rate of change is the highest.

5x = 7⋅ 55
x= 77
1/5/6 = 6x/6
x= 1/30
x+ 2.17 = 5
x+ 2.17 = 5 - 2.17 = 5 - 2.17
x=2.83
Step-by-step explanation:
Answer:
Step-by-step explanation:
1) [tex]\frac{5}{7}x = 55\\[/tex]
Multiply both sides by 7,
[tex]7*\frac{5}{7}x=55*7\\[/tex]
[tex]5x = 55 * 7[/tex]
Now divide both sides by 5
[tex]\frac{5}{5}x=\frac{55*7}{5}\\\\x = 11*7\\\\x = 77[/tex]
ANS: x = 77
2) 6x = 1/5
Divide both sides by 6
[tex]\frac{6}{6}x=\frac{1}{5*6}\\\\x = \frac{1}{30}[/tex]
3) 2.17 + x = 5
Subtract 2.17 from both sides
2.17 - 2.17 +x = 5 - 2.17
x = 2.83
[tex]4) \frac{20}{3}=\frac{10}{9}x[/tex]
Multiply both sides by 9
[tex]\frac{20}{3}*9=\frac{10}{9}x*9\\\\20*3=10x\\[/tex]
Divide both sides by 10
[tex]\frac{20*3}{10}= \frac{10}{10}x\\\\2*3 = x\\\\x = 6[/tex]

Answer: p = 75 + 250
Equation of the situation, in slope-intercept form is given as .
Where,
b = y-intercept
m = slope
n = number of computers sold
p = total cost
All we need to find is the value of m and b.
Using two pairs from the table of values, (4, 550) and (6, 700):
Substitute n = 4, p = 550, and m = 75 in , and find the value of b.
Subtract 300 from each side
b = 250
Substitute m = 75, and b = 250 in
