90° = pi/2 radians
see image
180° is pi radians.
pi radians is equivalent to 180 degrees, option B is correct.
What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
The radian equivalent of 180° is pi radians.
This is because a full circle is 360°, which is equivalent to 2 pi radians. Therefore, half of a circle or an angle of 180° is equivalent to half of 2 pi radians, which is pi radians.
Hence, pi radians is equivalent to 180 degrees, option B is correct.

Answer:
7.722[tex]cm^2[/tex]
Step-by-step explanation:
Work out the area of the circle
By the length of the square, you know the diameter of the circle is 12 cm so the radius is 6cm. Then you can calculate the area of the circle by doing
[tex]6^{2}[/tex]π =36π [tex]cm^{2}[/tex]
Work out the area of the square
12 x 12 = 144 [tex]cm^{2}[/tex]
So the bit not occupied by the circle will be 144- 36π = 30.888 [tex]cm^2[/tex]
However, the shaded area is just 1/4 of this bit so 30.888 / 4 = 7.722 [tex]cm^2[/tex]

Use a system of equations to solve the following problems
1) Find the value of two numbers if their sum is 11.9 and their difference is 0.5.
Answer:
The answer is x= 6.2 and y= 5.7
Step-by-step explanation:
Let the two numbers be x and y.
1st condition:
x+y= 11.9 --- (1)
2nd condition:
x-y=0.5--- (2)
Solving 1 and 2
x+y= 11.9 --- (1)
x-y=0.5--- (2) (here +y and -y will get cancelled)
_____________
2x= 12.4
x= 12.4/2 = 6.2
∴x= 6.2
Now, put x= 6.2 in equation (1) ( u can put in eqn 2 also)
6.2+y= 11.9
y= 11.9-6.2= 5.7
∴y= 5.7
To recheck you can put the value of x and y in any of the eqns.
The LHS will be equal to RHS if the values we got are correct.

Step-by-step explanation:
Segment AB has point A located at (4, 2). If the distance from A to B is 3 units, which of the following could be used to calculate the coordinates for point B? 3 = square root of the quantity of x minus 2 all squared plus y minus 4 all squared 3 = square root of the quantity of x minus 4 all squared plus y minus 2 all squared 3 = square root of the quantity of x plus 2 all squared plus y plus 4 all squared 3 = square root of the quantity of x plus 4 all squared plus y plus 2 all squared
The equation that can be used to find the coordinates of B given the coordinates of A and the length of the line segment AB is given by: Option B: 3 =√[(x-4)² + (y-2)²]
What is the distance between two points ( p,q) and (x,y)?The shortest distance(length of the straight line segment's length connecting both given points) between points ( p,q) and (x,y) is:
[tex]D = \sqrt{(x-p)^2 + (y-q)^2} \: \rm units.[/tex]
For this case, we're specified that:
The coordinates of A are (4,2)
The distance from A to B = 3
Let the coordinates of B be (x,y), and (p,q) = (4,2), then we get;
[tex]D = \sqrt{(x-p)^2 + (y-q)^2}\\\\or\\\\3 = \sqrt{(x-4)^2 + (y-2)^2}\\[/tex]
Thus, the equation that can be used to find the coordinates of B given the coordinates of A and the length of the line segment AB is given by: Option B: 3 =√[(x-4)² + (y-2)²]

how many gallons of paint are needed for one coat on the entire exterior of the barn, including roof?
A bran with the dimensions shown is to be painted. One gallon of pain covers 400 square feet. 23 gallons of pain is need for the one coat of the barn. Option B is correct.
Given that,
A bran with the dimensions shown is to be painted.
One gallon of pain covers 400 square feet.
We have to find how much gallon of paint for one coat on the entire external of the bran, including the roof.
So,
We can see in the picture
1 side of the barn is rectangle with length and breath that is 24 feet and 60 feet.
1 side of the barn is square with side 40 feet.
The front upper side has a triangle with height 21 feet.
Now, We find the area of the rectangle.
Area of rectangle is length × breath
=24feet×60 feet
=1440 square feet
1440 square feet divided by 400 square feet
1440/400=3.6
So, the bran has 2 rectangular sides so 3.6+3.6=7.2
Now, we find the area of square.
Area of square is side × side
=40 feet ×40 feet
=1600 square feet
1600 square feet divided by 400 square feet.
1600/400=4
So, the barn has 2 square side so 4+4=8
Now, we find the area of triangle.
Area of triangle is 1/2×breath ×height.
=1/2×40 feet×21 feet
=1/2×840 square feet
=420 square feet
420 square feet divided by 400 square feet.
420/400=1.05
So, the barn has 2 triangles back and front so 1.05+1.05=2.1
Now, we find the area of roof
Roof is in rectangle with breath 60 feet and height 21 feet
Area of rectangle is length × breath
=60 feet ×21 feet
=1260 square feet
1260 square feet divided by 400 square feet.
1260/400=3.15
So, the barn has 2 rectangle roof so 3.15+3.15=6.3
Now, Adding all the areas we get
=7.2+8+2.1+6.3
=23.6
Therefore, approximately 23 gallons of pain is need for the one coat of the barn. Option B is correct.

[tex]\large\boxed{\tt x^{\circ}= 90^{\circ}}[/tex]
Step-by-step explanation:
[tex]\textsf{We are asked to find the value of x.}[/tex]
[tex]\textsf{The value of x is an angle for this triangle.}[/tex]
[tex]\textsf{Note that we are given 2 other angles, we can use what is given to us to solve for x.}[/tex]

Which two terms in (3+14) +27 could you add to get a multiple of ten?
Answer:
3 and 27
Step-by-step explanation:
Step 1: Determine which two terms we can use
We have the following numbers to choose from: 3, 14, 27
Adding two numbers to get a multiple of ten means that the number that we come up with needs to be divisible by ten. For example: 20, 30, 50, 100 are all multiples of ten.
In this example the only one that would add up to create a multiple of ten is 27 and 3 which would give us 30 which is a multiple of 10.
Answer: 3 and 27

Suppose that there are two types of tickets to a show advance and same day the combined cost of one advance ticket and one same-day ticket is $70 for one performance 20 advance tickets and 35 same day tickets were sold.The total amount paid for the tickets was $1850.what was the price of each kind of ticket
The price of the advance ticket is $40 and the price of the same day tickets is $30.
What are the linear equations that reperesent the question?a + b = $70 equation 1
20a + 35b = 1850 equation 2
Where:
a = cost of one advance ticket
b = cost of one same day ticket
What is the cost of one same day ticket?
Multiply equation 1 by 20
20a + 20b = 1400 equation 3
Subtract equation 3 from equation 2
15b = 450
Divide both sides by 15
b = $30
