Answer:
These methods convert everything to radians
Step-by-step explanation:
Length of arc DC fromula is radius*angle in radians
Radius of the circle of DC is 8 cm aka the outer circle.
The angle inside is 130 degrees, in radians convert and multiply by 180/[tex]\pi[/tex]
givong 130 degrees to be 13/18π
using formula, arc DC is 8*13/18π
=52/9π (in terms of pi) or 18.15 cm
or 130/360*(2π8)=18.15 (not using radians)
Length of arc QT regards the inner circle of radius 4 cm. Convert 130 degrees to radians. Using same formula as above, length of arc =4*13/18π
=26/9π or 9.08 cm
or 130/360*(2π4)=9.08 (not using radians)
Area of sector DEC suspended angle is 130 degrees of 13/18π radians. regarding large outer circle radius 8 cm.
Use formula 0.5*r^2*angle in radians fro area of sector gives:
0.5*8^2*13/18π
=208/9π or 72.61 cm^2
or 130/360*(π8^2)=72.61 (not using radians)
The area of sector QET angle 13/18πv rad and radius 4 cm using same forumla as above gives
0.5*13/18π*4^2
=52/9π or 18.15cm^2
or 130/360*(π4^2)=18.15 (not using radians)
Radian measure of angle DEC is 130 degrees again convert to radians by multiplying by π/180 gives
=13/18π
Radian measure of angle QET IS ALSO 130 degrees also
=13/18π

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

What is the surface area of the box?
O A. 21 square centimeters
B. 30 square centimeters
C. 18 square centimeters
O D. 42 square centimeters
Answer:
We can split the solid into 6 rectangles
Rectangle1 with sides (2cm, 3cm)
Rectangle2 (square) with sides (3cm, 3cm)
Rectangle3 with sides (2cm, 3cm)
Rectangle4(square) with sides (3cm, 3cm)
Rectangle5 with sides (2cm, 3cm)
Rectangle6 with sides (2cm, 3cm)
Area of rectangle = Length x Breadth
[tex]area \ of \ rectangle1 = 6cm^2\\\\area \ of \ rectangle2 = 9cm^2\\\\area \ of \ rectangle3 = 6cm^2\\\\area \ of \ rectangle4 = 9cm^2\\\\area \ of \ rectangle5 = 6cm^2\\\\area \ of \ rectangle6 =6cm^2\\[/tex]
The total surface area = 6 + 9 + 6 +9 + 6 +6 = 42 square centimeters
option D
The total surface area of all 6 rectangles is 42 square centimeters.
We can split the solid into 6 rectangles
Rectangle1 with sides (2cm, 3cm)
Rectangle2 (square) with sides (3cm, 3cm)
Rectangle3 with sides (2cm, 3cm)
Rectangle4(square) with sides (3cm, 3cm)
Rectangle5 with sides (2cm, 3cm)
Rectangle 6 with sides (2cm, 3cm)
What is the area of the rectangle?
Area of rectangle = Length x Breadth
Therefore the area of rectangle1=6cm^2
Area of the rectangle2=9cm^2
Area of the rectangle3=6cm ^2
Area of the rectangle4=9cm^2
Area of the rectangle5=6cm^2
Area of the rectangle4=6cm^2
The total surface area = 6 + 9 + 6 +9 + 6 +6 = 42 square centimeters

Write an equivalent expression to 2x + 3 + 5(x+ 6) by combining like terms
Answer:
7x + 33
Step-by-step explanation:
Distribute the multiplication in the last term: 5(x + 6) becomes 5x + 30. Then, 2x + 3 + 5(x+ 6) becomes 2x + 3 + 5x + 30. 2x and 5x are 'like terms' and add up to 7x; 3 and 30 are also like terms of a different type (constants) and add up to 33.
Thus we have the equivalent, simpler expression 7x + 33.
Which option below demonstrates the correct notation for a continuous set of all numbers between 5 and 6, not including 5, but including 6?
Answer:
The set is (5, 6]
Step-by-step explanation:
Ok, let's see the different possibles notations to describe sets.
If we want to describe a discrete set, we use {}
Like in the set:
{1, 2, 3}
That set only contains the numbers 1, 2, and 3.
If we want to describe a continuous set that does not include the extremes, we use ()
For example:
(1, 3)
Contains all the numbers between 1 and 3, but does not include 1 and 3.
If we want to include the extremes, we need to use []
[1, 3]
This set is all the numbers between 1 and 3, including the values 1 and 3.
And we can mix these last two notations, so if we want a set that includes all the numbers between 5 and 6, not including 5 but including 6, we need to write:
(5, 6]

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.

What is the area of the hexagon below? only real answers
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:
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.

help!! what are these angle measures
Answer:
m1 = 62.5
m2 = 62.5
m3 = 55°
m4 = 75°
m5 = 50°
Step-by-step explanation:
m1: Sides 1 and 2 are congruent so angle will be the exact same as m2:
180° - 55° = 125 | 125 / 2 = 62.5°
m2: same as m1; 62.5°
m3: equivalent to 55° due to its location
m4: angle of a line is 180° so 180° - 105° = 75°
m5: angles of triangle add to 180° so 180° - (75° + 55°) = 50°

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.
