PLEASE HELP ITS DUE TOMORROW Rina draws hexagon GHJKLM. She rotates this figure by 180° about the origin to create hexagon G'H'J'K'I'M'.
Which THREE statements are TRUE?
A
G'H' is parallel to L M.
B
ZG'M'L' is a right angle.
С
J'K' is perpendicular to GM
D
ZH'J'K' is congruent to ZHJK.
E
J'K' has twice the length as JK.
Answer:
A, B, D
Step-by-step explanation:
C is wrong. J'K' is not perpendicular to GM
E is wrong. Rotating the figure 180 degrees, does not change the size of any line segments. So J'K' cannot be twice the length of JK

A farmer rotates wheat, corn, and soybean crops on her farm the farmer produces 293 bushels of produce and sells them for a total of $1,557
The average amount earned based on the information given is $5.31 per product.
Number of farm products = 293
Total amount earned = $1557
Therefore, the average amount will be gotten by dividing the total amount by the number of farm products and this will be:
= $1557/293
= $5.31
In conclusion, the average will be $5.31.

For this year‘s prom, 35/12 grade students and 28th 11th grade students voted on the theme. The segment take a bar graph below shows the distribution of responses.
Based on the segmented bar graph, does there appear to be an associates between grade level and prom theme?
A yes, there is a different number of students in each class.
B yes, it appears that the 12th grade students prefer the 1920s more than the 11th grade students, and prefer the beach party less.
C no, both distributions of student preferences have the same four categories.
D no, both distributions of student preferences have about the same preference for each of the prom themes.
E no, by the same number of students in each class. Preferred winter wonderland and masquerade ball as prom themes.
Answer:
B
Step-by-step explanation:
Logically and if you observe the graph closely ┐( ∵ )┌
The answer is yes, there appears to be an association between grade level and prom theme based on the segmented bar graph. The Option B is correct
Is there an association between grade level and prom theme?The graph shows that 12th-grade students prefer the 1920s theme more than the 11th-grade students do, and they also have a lower preference for the beach party theme. This indicates a difference in preferences between the two grade levels for these specific prom themes.
This graph provide information on whether both distributions have the same four categories or whether they have the same preference for each of the prom themes, so, its indicate whether the number of students in each class is the same or not.

Subtract the linear expressions. (−2.6x+4.2)−(3.9x+2.5) What is the difference? Enter your answer in the box.
Answer:
-13x/2+1.7
Step-by-step explanation:
The difference of the given expression is - 6.5 x + 1.7.
Given that, (−2.6x+4.2)−(3.9x+2.5).
What is the subtraction of expressions?To subtract an algebraic expression from another, we should change the signs (from '+' to '-' or from '-' to '+') of all the terms of the expression which is to be subtracted and then the two expressions are added.
Now, (−2.6x+4.2)−(3.9x+2.5)
= (-2.6x-3.9x)+4.2-2.5
= - 6.5 x + 1.7
Therefore, the difference of the given expression is - 6.5 x + 1.7.

Answer:
The product is 240.
Step-by-step explanation:
The product is always when you multiply numbers together.
Answer:
Using 15 times table, we have 15 times 8 = 15 × 8 = 120. Hence, 15 times 8 is 120. b) First, we will write 15 times 7 minus 5 mathematically.
Table of 15 up to 20.
15 × 11 = 165 15 × 16 = 240

Answer:
∠c = 180 - 3x
Step-by-step explanation:
Triangle interior angles = 180.
Remember this fact:
The sum of the angles of any polygon = (number of sides in the figure - 2)(180)
∠a = x
∠b = 2x
∠c = 180 - 3x

What is the equation of the line that passes through the point (6,14) and is parallel to the line with the following equation? y=-4/3x -1
Answer:
[tex]y=\displaystyle-\frac{4}{3}x+22[/tex]
Step-by-step explanation:
Hi there!
What we need to know:
Linear equations are typically organized in slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-interceptParallel lines always have the same slope (m)Determine the slope (m):
[tex]y=\displaystyle-\frac{4}{3}x -1[/tex]
The slope of the given line is [tex]\displaystyle-\frac{4}{3}[/tex], since it is in the place of m in y=mx+b. Because parallel lines always have the same slope, the slope of a parallel line would also be [tex]\displaystyle-\frac{4}{3}[/tex]. Plug this into y=mx+b:
[tex]y=\displaystyle-\frac{4}{3}x+b[/tex]
Determine the y-intercept (b):
[tex]y=\displaystyle-\frac{4}{3}x+b[/tex]
To find the y-intercept, plug in the given point (6,14) and solve for b:
[tex]14=\displaystyle-\frac{4}{3}(6)+b\\\\14=-8+b\\b=22[/tex]
Therefore, the y-intercept of the line is 22. Plug this back into [tex]y=\displaystyle-\frac{4}{3}x+b[/tex]:
[tex]y=\displaystyle-\frac{4}{3}x+22[/tex]

Answer:
Option 4) y - 1 = -2(x - 0)
Step-by-step explanation:
Given the slope, m = -2, and the y-intercept, (0, 1):
Substitute these values into the following point-slope form:
y - y1 = m(x - x1)
y - 1 = -2(x - 0) ← This is the point-slope form given the slope, m = -2, and the y-intercept, (0, 1).
Therefore, the correct answer is Option 4: y - 1 = -2(x - 0)
