What is the distance between the points (1,6) and (-7,3) on a standard coordinate plane?
39
73
173
55
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)

A horse travels at about 65 kph. At this rate, how far can it travel in 20 minutes
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.....

I kinda need help and an explanation Cant understand
Answer:
look in explanation
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.

Sandra drove 117 miles in an hour and 30 minutes to visit her son at college, without stopping. If the speed limit is 60 mph, explain why she should or should not get a speeding ticket. Make sure to include mathematical computations in your answer.
Answer:
She should get a speeding ticket. The speed limit is 60mph and her speed was 78 mph, 18 miles over the speed limit.
Step-by-step explanation:
She drove 117 miles in 90 minutes.
117/90 = 1.3 miles per minute
1.3 miles x 60 minutes = 78 mph

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
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°

p = 180-140
p= 40
Answer:
The answer is 40°. W and X are congruent to each other.
Define:
Congruent: Triangles that have both the same shape and the same size.
Straight line= 180degrees

When 3 times a number is added to the square of the number, the result is 40. Determine the number
Answer:
5 or -8
Step-by-step explanation:
[tex](3 \times x) + x {}^{2} = 40[/tex]
[tex]3x + {x}^{2} = 40[/tex]
[tex] {x}^{2} + 3x - 40 = 0[/tex]
using factorization method
[tex]( {x}^{2} + 8x) ( - 5x - 40) = 0[/tex]
[tex]x(x + 8) - 5(x + 8) = 0[/tex]
[tex](x - 5)(x + 8) = 0[/tex]
[tex]x - 5 = 0[/tex]
or
[tex]x + 8 = 0[/tex]
[tex]x = 5[/tex]

You are making a scale model of a sports field. The
actual field is a rectangle with a length of 315 ft and a
width of 300 ft. Your scale model is 15 in. wide. What is
its length in inches?
Answer:
15.75 inches
Step-by-step explanation:
You can use a ratio to find your answer by cross multiplying.
300 ft 315 ft
---------- = ----------
15 in x in
Cross multiplying would give you:
300x = 15 x 315
300x = 4725
x = 4725 / 300
x = 15.75 inches
I want need help because I’m having trouble on this question Evaluate: 2-4 =
Find the measure of each missing angle
I’ll give BRAINLEST!!
Answer:
angle 4 = 115°[vertically opposite angles]
angle 2+ angle 4=180°[linear pair]
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°
angle7+ 211°=360°
angle7=360°-211°
angle7=149°
angle7+angle6=180°[linear equation]
149°+angle6=180°
angle6=180°-149°
angle6=31°
angle4+angle6+angle3= 180°[by sum of all angles is 180°]
115°+31+angle3=180°
146°+angle3=180°
angle3=180°-149°
anble3=41°
