angle1,2 , and angle3 form a straight line. If m angle3 is six more than twice m angle1 m angle2 is 27 less than m angle3 find m angle2
Answers
Since it's an angle on a straight line, the value of angle 2 is 23.25°
Angle 1 = m
Angle 2 = m - 27
Angle 3 = 2m + 6
It should be noted that the sum of angles in a straight line is equal to 180°, therefore we need to equate all the angles given to 180°. This will be:
m + (m - 27) + (2m + 6) = 180°
m + m - 27 + 2m + 6 = 180°
4m = 180° + 27° - 6°
4m = 201°
m = 201/4
m = 50.25°
Therefore, angle 2 will be:
m - 27 = 50.25 - 27 = 23.25°

Step-by-step explanation:
To solve you just need to divided the area by the length or width the question has provided. Please note I am in 7th grade.
Part 1 state the domain and range of the given relation.
Part 2 is the relation a function
{(-1, 2),(1, 2),(3, 2), (6, 2)}
Please help
Answers
A function is a relation in which NO two ordered pairs have the same first component and different second components.
The set of first components (x-coordinates) in the ordered pairs is the DOMAIN of the relation.
The set of second components (y-coordinates) is the RANGE of the relation.
Part 1:
Domain: {-1, 1, 3, 6}
Range: {2, 2, 2, 2}
Part 2:
To determine whether the given relation represents a function, look at the given relation and ask yourself, “Does every first element (or input) correspond with EXACTLY ONE second element (or output)?”
Remember that a function can only take on 1 output for each input.
It helps to plot the points on the graph and perform the Vertical Line Test (VLT):
The Vertical Line Test allows us to know whether or not a graph is actually a function. If a vertical line intersects the graph in all places at exactly one point, then the relation is a function.
As you can see in the attached screenshot, every vertical line drawn only has 1 point in it. This means that each x-value corresponds to exactly one y-value. The given relation passed the VLT. Therefore, the relation is a function.

Step-by-step explanation:
Seeing as most of your answers are wrong, I'll start from the beginning.
a rational number is a number that can be expressed as a fraction.
an integer is a whole number.
an irrational number is a number that cannot be expressed as a fraction.
an integer is also always a rational number.
Using this, we can sort the values.
-77/11 can be simplified as -7, which is an integer.
the square root of 144 is 12, which is an integer.
0.25 is a decimal that can be expressed as a fraction, which makes it a rational number that is not an integer.
the square root of 20 is a value that cannot be expressed as a fraction, which makes it irrational.
17/4 is a fraction that is not a whole number, which makes it a rational number but not an integer.
finally, 2*the square root of 10 is irrational.

A horse travels at about 65 kph. At this rate, how far can it travel in 20 minutes
Answers
Answer: Approximately 21.667 km
This value as a fraction is 65/3, but I think the decimal form is probably more practical in real world settings.
======================================================
Work Shown:
20 min = 1/3 of an hour, since 20/60 = 1/3. In other words, there are three chunks of 20 minutes that make up a full hour.
distance = rate*time
distance = (65 kph)*(1/3 hr)
distance = (65*1/3) km
distance = (65/3) km
distance = 21.667 km which is approximate
Answer:
Distance rate=Rate x Time
Distance= (75 km/h) 20 mins
Convert 20 mins in hours= 1/3 h
Distance= (75 km/h) (1/3 h)= 25 km.....

angle 2+ 115 = 180°
angle 2 = 180°-115°
angle 2=65°
angle1+angle2+80°=180°[sum of all angles is 180°]
angle1+65°+80°=180°
angle 1 + 140° = 180°
angle 1=180°-140°
angle1 =40°
angle2= angle5[vertically opposite angles]
angle7+angle5+61°+90°=360°[sum of all angles of quadrilateral is 360°]
angle7+ 65°+ 61° +90°=360°

What is the distance between the points (1,6) and (-7,3) on a standard coordinate plane?
39
73

55
Answers
Step-by-step explanation:
I think you are missing the square root signs or so in the answer options.
the distance between 2 points is calculated by using Pythagoras for right-angled triangles.
c² = a² + b²
c is the Hypotenuse of the triangle and the distance between the points, which are the end points of the Hypotenuse.
a and b are the legs and enclose the 90 degree angle. they are the differences of the x and y coordinates between the 2 points.
so,
distance² = (1 - -7)² + (6 - 3)² = 8² + 3² = 64+9 = 73
=>
distance = sqrt(73)
