Hello!
The airplane is flying at 720 kilometers per hour. Since the plane is flying 720 kilometers, it would only take one hour. So the plane would take 1 hour to travel 720 kilometers per hour.
I hope this helps!

From the above expression we get,
=》x + y = 7 - [1]
=》3x - 2y = 11 - [2]
now, let's solve :
multiplying [1] by 3
=》3x + 3y = 21
=》 3x - 2y = 11
subtracting
now, subtracting [2] from [1]
=》3x + 3y - 3x + 2y = 21 - 11
=》5y = 10
=》y = 2
now, plugging the value of y as 2 in equation [1]
=》x + y = 7
=》x + 2 = 7
=》x = 5
So, value of :
x = 5y = 2Acute Lines that never intersect Right An angle that is more than 180°, less than 360° Obtuse An angle that is more than 0°, less than 90° Straight Intersecting lines that form 90° angles Reflex Measures exactly 90° Parallel An angle that is more than 90°, less than 180° Perpendicular Measures exactly 180° find their partner.

Answer:Acute An angle that is more than 0°, less than 90°
Right Measures exactly 90°
Obtuse An angle that is more than 90°, less than 180°
Straight Measures exactly 180°
Reflex An angle that is more than 180°, less than 360°
Parallel Lines that never intersect
Perpendicular Intersecting lines that form 90° angles
Step-by-step explanation:An acute angle is an angle that is between 0° and 90°. Examples are 50°, 25° e.t.c
A right angle is formed when two lines that are perpendicular to each other intersect. The angle formed is exactly 90°.
An obtuse angle is an angle that is between 90° and 180°. Examples are 101°, 98.9°
A straight angle is an angle that is exactly 180°. It is sometimes called flat angle.
A reflex angle is an angle that is between 180° and 360°. Examples are 340°, 192°
A parallel angle is an angle formed by lines that never intersect.
A perpendicular angle is formed by lines that intersect by forming an angle of 90° to each other.
answer is 90 because 360 divided by two equals is 180 then 180 divided by two equal 90 mean answer is 90

A bowl contain
- 3 red erasers
- 4 blue erasers
- 6 green erasers
- 7 erasers
An eraser will be drawn from the bowl and replace 50 times. What is a reasonable prediction for the number of the number of times a green eraser will be drawn?
Answer:
15 times
Step-by-step explanation:
6 green erasers / 20 total erasers =0.3
0.3(50) = 15
The number of times a green eraser will be drawn will be 15 times.
What is the expected value?The expected value is given below.
E(x) = np
Where n is the number of samples and p is the probability.
A bowl contains 3 red erasers, 4 blue erasers, 6 green erasers, and 7 erasers.
The probability of getting a green eraser will be calculated as,
P = 6 / (3 + 4 + 6 + 7)
P = 6 / 20
P = 0.30
Then the expected value is calculated as,
E = 0.30 x 50
E = 15
The number of times a green eraser will be drawn will be 15 times.
More about the expected value link is given below.

An earring has the shape of a rhombus. The height is 5.2 mm and the
area of the earring is 39 mm2. What is the length of each side of
the earring?
9514 1404 393
Answer:
7.5 mm
Step-by-step explanation:
As with any parallelogram, the area of a rhombus is given by ...
A = bh
Using the given values, we find ...
39 mm² = b(5.2 mm)
b = (39 mm²)/(5.2 mm) = 7.5 mm
The length of each side is 7.5 mm.
Answer:
Solution given:
height=5.2mm
Area of rhombus=39mm²
we have
Area of rhombus=base*height
39=5.2×base
base=39/5.2
base=7.5mm
the length of each side of
the length of each side ofthe earring is 7.5mm.

If the measure of angle 0 is 7/6. The equivalent measurement in degrees is
|blank| °
Answer:
the angle in degree is 30°
If the measure of the angle in radian form is 7π/6 then it is 210° in degrees form.
What is angle?An angle is basically an inclination of surface towards a object. It is measured in degrees as well as in radian.
How to convert angle into degrees?We have been that the angle is 7π/6 and we have to convert this angle into degrees.
We have to just put π=180 to convert the radian form into degrees.
Angle=7*180/6
=7*30
=210°
Hence if the measure of the angle in radian form is 7π/6 then it is 210° in degrees form.

Mean__
Median__
Mode__
Range__
Answer:
Mean: 6
Median: 6
Mode: 8
Range: 5
Step-by-step explanation:
Mean: is the sum of all numbers divided by the amount of numbers.
Median: the middle number.
Mode: the number that is often being occurred.
Range: the difference between the beginning number and the ending number.
--------------------------------------------------------------------------------------------------------------
Mean: 7 + 3 + 5 + 6 + 4 + 8 + 4 + 7 + 8 + 8 = 60 divided by 10 equals 6.
Median: 7, 3, 5, 6, 4, 8, 4, 7, 8, 8. The median is between those numbers so we're going to identify the number between 4 and 8. well obviously is 6 but if you want to do some math then add the two medians and then divided by two.
Mode: 7,3,5,6,4,8,4,7,8,8. The mode in this case is 8 because it is being used the most out of all of the other numbers.
Range: 7, 3, 5, 6, 4, 8, 4, 7, 8, 8. the range is 5 (in this case) because it is the difference between the largest number and the smallest number.

A sample of 144 was taken from a population with a standard deviation of 36
inches. What is the margin of error for a 68% confidence interval?
A. 9
B. 6
C. 3
D. 12
Answer:
9 inches
Step-by-step explanation:
The population is within 6 standard deviations of the mean with a confidence of 99.7 percent, 3 above and 3 below
The standard deviation of the sample mean is equal to the population standard deviation divided by the square root of the sample size
population standard deviation = 36
sample size = 144
standard deviation of the sample mean = 36/ sqrt(144)
=36/12
=3
The margin of error is the number of standard deviations above the mean * the standard deviations
margin of error = 3 * 3
= 9 inches

Answer: 24 m squared
Step-by-step explanation:
Lets break this down step by step. When you see an irregular polygon and want to find the area, you can break it down into smaller shapes.
I have split the shape into a parallelogram and a rectangle.
Area of parallelogram : 6*2 (formula = bh)
Area of rectangle: 6*2 (formula = bh)
Now we add the areas of both the parallelogram and rectangle together to get 24m squared.
Answer:
24 m²

The length of a shadow of a building is 26 m. The distance from the top of the building to the tip of the shadow is 37 m. Find the height of the building.
Answer:
26.3 m
Step-by-step explanation:
The length of a shadow of a building is 26 m. The distance from the top of the building to the tip of the shadow is 37 m. Find the height of the building.
We solve the above question using Pythagoras theorem
c² = a² + b²
Where
c = Longest part of the triangle = 37 m
a = Height of the triangle = ?
b = Length of the shadow = 26 m
Hence:
37² = a² + 26²
a² = 37² - 26²
a = √37² - 26²
a = √(693)
a = 26.324893162m
Approximately = 26.3 m
