With the help of angles we can say that ∠HJI=∠FJG.
What are angles?When two straight lines or rays intersect at a single endpoint, an angle is created.The vertex of an angle is the location where two points come together.The Latin word "angulus," which means "corner," is where the term "angle" originates.Vertex: The intersection of two lines or sides at an angle is called a vertex. In the diagram, O is the vertex.Arms: The angle's two sides linked at a single end. The arms of an angle are OA and OB.Initial Side: A straight line from which an angle is drawn, sometimes referred to as the reference line. The reference line is OB.The side that the angle measurement is done up to is known as the terminal side. OA is the terminal side in the diagram that is shown below.Acc to our question-
∠HJI=∠FJG=180 , they are forming linear pairs.due to transitive property of inequality we can say that-they both are equal and congruent.Hence, ∠HJI≅∠FJG are equal and congruent.

Flying against the wind, an airplane travels 7680 kilometers in 8 hours. Flying with the wind, the same plane travels 12,420 kilometers in 9 hours. What is the rate of the plane in still air and what is the rate of the wind?
Answers
The rate of the plane in still air is a = 1170 km/hr, and the rate of the wind is w = 210 km/hr.
What is speed?The distance covered in a unit of time is known as speed.
Given that, the airplane travels 7680 km in 8 hours flying against the wind, and 12420 km in 9 hours.
Therefore, the rate of the airplane against the wind is:
7680/8
= 960 km / hr
The rate of the airplane with the wind is:
12420/9
=1380 km / hr
Let the rate of the airplane in still air be a and the rate of the wind be w.
The net rate while flying against the air is:
a - w = 960 (1)
The net rate while flying with the wind is:
a + w = 1380 (2)
Add equations (1) and (2):
2a = 2340
a = 1170 km/hr
Substitute a = 1170 into equation (1):
1170 - w = 960
1170 - 960 = w
210 = w
Hence, the rate of the plane in still air is a = 1170 km/hr, and the rate of the wind is w = 210 km/hr.

the length of a rectangle is increasing at a rate of 6 cm/s and its width is increasing at a rate of 8 cm/s. when the length is 12 cm and the width is 10 cm, how fast is the area of the rectangle increasing (in cm2/s)?
Answers
The area of the rectangle is increasing at the rate of 156 [tex]cm^{2}[/tex]/s .
Let the length (cm) be l , width (cm) be w , area be A ([tex]cm^{2}[/tex]) and time (s) be t .
Given : dl / dt = 6 cm/s and dw / dt = 8 cm/s
Area of rectangle = l * w
Differentiating wrt. t ,
dA / dt = ( l ) ( dw / dt ) + ( dl / dt ) ( w )
Therefore , dA / dt = 8l + 6w
Hence , when l = 12 cm and w = 10 cm
dA / dt = ( 8 * 12 ) + ( 6 * 10 )
dA / dt = 156 [tex]cm^{2}[/tex]/s .

What is the equation of the line that passes through the point (-4, 2) and has a
slope of 1/4?
Answers
Answer:
y=1/4x+3
Step-by-step explanation:
To write an equation, let's infer we need to write it in slope-intercept form. We need the y-intercept. We can plug 1/4 and (-4,2) into y=mx+b, to solve for b. We have:
2=1/4*-4+b
2=-1+b
3=b
Since we have the slope, 1/4, we can create our equation:
y=1/4x+3
Solve for b in (y=mx+b):
b=y-mx
b=2-(1/4)(-4)
b=2+1
b=3
So the equation is y= (1/4)x + 3
Can someone please explain to me in simple words how to construct the circumcenter and incenter of a triangle? I've tried watching videos and reading articles but the wording is too complicated.
I'm doing the IXL skill if that helps
Answers
The circumcenter is where three perpendicular bisectors intersect and the incenter is where the three angle bisectors intersect.
What is circumcenter?The circumscribed circle or circumcircle of a polygon in geometry is a circle that passes through each of the polygon's vertices. This circle's circumcenter and circumradius are its centre and radius, respectively.
Construct angle bisectors of each angle of the triangle and their intersection point gives the incenter.
To find Circumcenter:
Construct perpendicular bisectors of all sides of the triangle and their intersection point gives the circumcenter.
Circumcenter Theorem: It states that the vertices of a triangle are equidistant from the circumcenter.
Incenter Theorem: It states that the incenter is equidistant from the sides of the triangle.

Answers
The homogeneity of variance is an assumption for the one-way between-subjects anova means each population from which the samples are drawn has the same level of variation.
What is homogeneity of variance?Both t tests and F tests (also known as analyses of variance, or ANOVAs) are based on the premise that the population variances (i.e., the distribution, or "spread," of scores around the mean) of two or more samples are identical. The independent samples t-test and ANOVA employ the t and F statistics, which, provided that group sizes are equal, are often resistant to breaches of the assumption. A ratio of less than 1.5 between the largest and smallest group can be used to identify equal group sizes.
The independent samples t-test and ANOVA make the assumption of homogeneity of variance, which states that all comparison groups have the same variance.

The geometric mean of a number and nine times the number is 30. What is the number?
Answers
For the given geometric mean of a required number and nine times the required number is 30 then the required number is equal to 10.
As given in the question,
Geometric mean GM = 30
Let us assume the first number is x
and second number i.e. 9 times of the first number is 9x
By the formula GM = [tex]\sqrt{x.y}[/tex]
Now putting the value
30 = [tex]\sqrt{x.9x}[/tex]
30 = [tex]\sqrt{9x^{2} }[/tex]
30 = 3x (∴ square root of 9 is 3 and sq root of x² is x)
10 = x (by dividing both the side by 3)
Therefore, for the given geometric mean of a required number and nine times the required number is 30 then the required number is equal to 10.

Answers
The price of one kilogram of jelly bean and gummy worms is $7 and $8 respectively.
Let the price of 1 kilogram of jelly bean cost be x
and the price of 1 kilograms of gummy worms be y
Dean bought 2 kilograms of jelly beans and 3 kilograms of gummy worms
for $38
2x + 3y = 38......equation 1
Sue bought 3 kilograms of jelly beans and 3 kilograms of gummy worms
for $45
3x + 3y = 45........equation 2
Subtracting equation 2 from equation 1
2x + 3y - (3x + 3y) = 38 - 45
2x - 3x + 3y - 3y = -7
-x = -7
x = 7
2(7) + 3y = 38

Answers
There is a 0.990025 probability that this area won't experience a major earthquake in the next two years.
Define probability.In the field of mathematics called probability theory, random occurrences are studied. The outcome of a random event can take any number of distinct shapes, but it cannot be anticipated before it occurs. The outcome is believed to have been decided by chance.
Given,
In a region where large earthquakes of magnitude 7 or higher have occurred about once every 200 years,
First, the likelihood of an earthquake with a magnitude of 7 or higher is 1/200 = 0.005.
The likelihood of there not being an earthquake is then requested, and it is 1-0.005 = 0.995.
The likelihood that there won't be an earthquake in two years is then

an insurance company won't repair a car when the cost of the repair is 25% or more of the car's value. if a repair costs $1400, what is the value of the car (in interval notation)?
Answers
The interval of the cost of the car is [5600, ∞).
Here we have to find the cost of the car.
Let x be the cost of the car.
So from the question, we have that the cost of the repair is 25% or more of the car's value.
So we have to find the interval notation of the cost of the car.
x ×25% ≥ 1400
x × 25/100 ≥ 1400
x ≥ 1400× 100/25
x≥ 5600
So we get that the cost of the car is greater than $5600.
