The angles have the same measure because of the corresponding angles theorem.
[tex]\huge\boxed{112^\circ}[/tex]
To solve this problem, we need to understand the basic rules of transversals across parallel lines.
When a line crosses another line or lines, it is a transversal.
When the two lines it crosses are parallel, the eight angles formed have interesting properties that we can use.
For this question, we will look at corresponding angles. If two angles meet these two conditions, they are congruent:
Both angles are on the same side of the transversal.One angle is interior (between the parallel lines) and the other is exterior.These two conditions are met for [tex]\angle JIK[/tex] and [tex]\angle GFI[/tex], so they are congruent and their measures are equal.
This means that [tex]m\angle JIK=m\angle GFI=\boxed{112^\circ}[/tex]

3 meters of cloth is the ratio of 3:7
When given 3 meters of cloth to divide in the ratio 3 : 7 then one part of the division will have 0.9 meters and the other side will have 2.1 meters.
How to use ratio to divide?The ratio is 3 : 7 which means that the 3 meters of cloth should be divided such that one part is 3 to the 7 of the other part.
First, find the denominator:
= (3 + 7)
= 10
The smaller part of the cloth:
= 3 / 10 x 3 meters of cloth
= 9 / 10 meters
= 0.9 meters
The larger part of the cloth:
= 7 / 10 x 3 meters of cloth
= 21 / 10
= 2.1 meters

Answer:
perimeter is 24in. sq
Step-by-step explanation:
6in. per side* 4 sides= 24in. perimeter
Answer:
48 inches
Step-by-step explanation:
The perimeter is the distance around the shape. To find it, add the length of each side together. Assuming each side has two small squares, then each side would be 12 inches. Add 12 + 12 + 12 + 12, in order to get 48

Hannah estimated that a bottle could hold 2.2 liters. The actual volume of the bottle was 2 litters. What was the percent error in hannas measurements?
Answer:
I dont have a direct answer but i think i can help.
Step-by-step explanation:
For example, 2%, read "percent", is two every hundred. When we have 100 liters of water, 2% is 2 liters. If we have 200 liters of water, then 2% is 4 liters. Converting a percentage into a fraction can be done by dividing by 100, following the definition of a percentage.

A student graphs 5x−y=7 on a coordinate plane. Which equation, when graphed on the same coordinate plane, will result in a system of equations with no solution? 5x−y=7 5 x − − y = 7 5x−y=1 5 x − − y = 1 x−5y=35 x − − 5 y = 35 x−5y=5
Answer:
5x−y=1
Step-by-step explanation:
An equation is a statement that shows the equality between two expressions.
An equation is said to have no solutions if after solving the equation and the result is a statement like a = b, where a and b are different numbers.
The equation after it is simplified would have the same coefficients and different constant.
Given:
5x−y=7
An equation that will result in a system of equations with no solution will have the same coefficient but different constant.
Hence 5x−y=1, would give a system of equations with no solution.
Simplifying gives:
7 = 1 (no solution)

Step-by-step explanation:
-6: y = -6
y = [tex]\frac{2}{3}[/tex] (-6)
y = -4
y = [tex]\frac{2}{3}[/tex] (-6) + 1
y = -4 + 1
y = -3
-3: y = -3
y = [tex]\frac{2}{3}[/tex] (-3)
y = -2
y = [tex]\frac{2}{3}[/tex] (-3) + 1
y = -2 + 1
y = -1
0: y = 0
y = [tex]\frac{2}{3}[/tex] (0)
y = 0
y = [tex]\frac{2}{3}[/tex] (0) + 1
y = 1
3: y = 3
y = [tex]\frac{2}{3}[/tex] (3)
y = 2
y = [tex]\frac{2}{3}[/tex] (3) + 1
y = 2 + 1
y = 3
6: y = 6
y = [tex]\frac{2}{3}[/tex] (6)
y = 4
y = [tex]\frac{2}{3}[/tex] (6) + 1
y = 4 + 1

Which graph represents a linear function?
Answer:
y + 2x = 10 (third option)
Step-by-step explanation:
We can see that every time x increases by one, y increases by -2, meaning that the slope is -2.
We also know that the y-intercept is 10 because that is the value of y when x is equal to 0.
Now, we can create the equation using the slope-intercept form (y = mx + b, where m is the slope and b is the y-intercept).
y = -2x + 10
If you look at the third option, that equation is just a rearranged form of our equation (y + 2x = 10).
This means that the third option is correct.
Answer:
C, or y+2x=1-
Step-by-step explanation:
Test them one by one. Put the y into the equation and the x in the equation. Whichever ones always work are the correct answer. Remeber, you have to consider all the possible values of x and y when you test them!

The mean can be misleading if you don't know the spread of data items. True or false...
Answer:
True
Step-by-step explanation:
When data is skewed toward the high or low end, the mean can be a misleading measure of central tendency. In such a case the central tendency for the data items shifts toward either the high or low end -- away from the mean. The median then becomes the better measure.
The mean could be misleading when we don't know the spread of data items is to be considered as the true.
Role of mean:
The mean do have the high impact on the extreme observations. In the case when the observation is high so automatically the remaining observations should be low due to which the mean should be increased.
So based on this, we can conclude that The mean could be misleading when we don't know the spread of data items is to be considered as the true.

The scale factor of a model plane to the actual plane is 1 to 20.
Find the wing area of the model if the wing area of the actual plane is 400 ft^2
Answer:
1 ft²Step-by-step explanation:
The scale factor = 1 : 20
The area is the product of two dimensions, so the area of the model part to actual part is:
1 ² : 20 ² = 1 : 400If the actual plane has wing area of 400 ft², then the model will have wing area:
400 ft² / 400 = 1 ft²Evaluate 8-m/n+p2 when m=8, n=2p =7

We have been given that
equation is 8-m/n+p²
where
m= 8;
n= 2;
and p= 7;
Substitution property - If a variable is equal to a specified amount, that amount can be directly substituted into an equation for the given variable.
By using substitution property in equation

average before the final exam for a course. That score includes everything but
the final, which counts for 25% of the course grade.
What is the best course grade your friend can earn?
What is the minimum score would your friend would need on the final to earn a 75% for the course?
%
Give answers accurate to at least one decimal place.
Answer:
best course grade: 84.25%least final grade: 63%Step-by-step explanation:
You have a course average of 79% that is 75% of your grade, and you want to know ...
the least final score for a course average of 75%the best possible course average.Weighted averageThe course average is computed as the weighed average of the course grade so far and the final grade. The weighs are 75% and 25%, respectively. In formula form, the relation between the final grade (f) and the course average (c) is ...
0.75(79) + 0.25f = c
Solving for f, we have ...
f = 4(c -59.25) = 4c -237
a) Best course gradeAssuming the best final grade is 100, the best course grade is ...
c = 0.25(100) +59.25 = 25 +59.25 = 84.25
The best course grade is 84.25%.
b) Least final gradeFor a course grade of 75%, the least final grade necessary is ...
f = 4(75) -237 = 300 -237 = 63
The minimum score on the final for a 75% for the course is 63%.

Additional comment
Here we have percentages with two different bases. The course grade percentages have a base of the greatest possible number of credits. The weight percentages have a base of the whole course grade. Working with percentages of percentages can be confusing if the base of the percentage is not clear.
We often find it easier to deal with grades expressed as a number 0 to 100, rather than as a percentage. That is what we have done here (except in the final answers). The final answer expresses the course grade as a percentage so as to be consistent with the problem statement.
