We will see that both angles are actually the same one (but in different units) so the symbol that we need to use is the equal symbol.
Which symbol correctly compares the two angles?
Here we have two angles, one in degrees and the other in radians, we want to compare them. To do it, we will need to write both of the angles in the same units.
The angles are:
pi/3 rads
60°
First, remember that:
pi rads = 180°
1 rad = (180°/pi)
With this, we can change the units of the first angle to get:
pi/3 rads = pi/3*(180°/pi) = 180°/3 = 60°
So both angles are actually the same angle, then the symbol that correctly compares them is the equal symbol.
pi/3 rads = 60°

Select all that are true for Triangle PQR
In other words, only choice A and choice D are false.
====================================================
Explanation:
An included angle is one between two given sides. Think of the angle sandwiched in between.
For choice A, the included angle is actually angle R. This is because the "R" shows up in QR and RP. This is the overlapping or shared letter between the segments. So we can see that statement A is false.
In contrast, choice B and choice C are true. Choice B is true because of what I mentioned in the previous paragraph. Choice C is true because Q shows up in both QR and PQ. It might help to draw out the diagram to see why this works.
------------------------
For choices D through F, we'll just take this logic in reverse.
The segment RP has angles R and P involved. In other words, segment RP is between angles R and P. We can rule out choice D since choice E is true.
Choice F is true as well because segment QP involves angles Q and P. No diagrams are needed but it might help to draw out the diagram to see what's going on.
------------------------
Overall, we have four true statements and they are choices B, C, E and F.

Which of the following is the graph of 2x+3y=6
Taking point (0,-2) of graph one and replacing in the equation;
2x+3y=6
2(0)+3(-2)=6
-6=6
So graph isn't the required graph.
Taking point (0,2) of graph 2;
2x+3y=6
2(0)+3(2)=6
6=6
So, graph 2 is the required graph.

Answer:
2 bicycles
Step-by-step explanation:
let no. of bicycles be xno.of tricycles = (6 -x)as there were 5 bicycles and tricycles
now,
a bicycle has 2 wheels a tricycle has 3 wheelstotal no.of wheels = 16
2x + 3(6 - x) = 16
2x + 18 - 3x= 16
2 - x = 0
2 = x
therefore, there are 2 bicycles.

Give an example of a real-world permutation in which repetition is allowed one in which repetition isn’t allowed.
Answer:
Example 1: The PIN code is an example when order is important. The PIN code 1234 is different from the PIN code 4321. When selecting more than one item without replacement and order is important, it is called a Permutation. When order is not important, it is called a Combination.
Step-by-step explanation:
When we hear the word "combination" in our daily life, we immediately think about the collection of things in the form of a set or a group. For instance, if anyone says that my bowl has a combination of apples, carrots, and bananas, then we immediately think that the bowl has three items. We are not concerned with the order in which these three things were put in the bowl. In mathematics, the combination means the number of ways in which different objects are combined to form a set.

T = 60°
Step-by-step explanation:
Angle S = 180° - 150° = 30°
Angle U = 90°
Therefore, angle T is given by
S + U + T = 180
30° + 90° + T = 180°
or
Angle T = 60°

HOPE IT HELPEDConsider a triangle A BC like the one below. Suppose that A = 100°, b =51, and c= 45. (The figure is not drawn to scale.) Solve the triangle. Carry your intermediate computations to at least four decimal places, and round your answers to the nearest tenth. If there is more than one solution, use the button labeled "or".
Answer:
[tex]A = 100^o[/tex]
[tex]B = 43.0^o[/tex]
[tex]C =37.0^o[/tex]
Step-by-step explanation:
Given
[tex]A = 100^o[/tex]
[tex]b = 51[/tex]
[tex]c =45[/tex]
Required
Complete the triangle (See attachment)
First, calculate side a using cosine's equation
[tex]a^2 = b^2 + c^2 -2bc \cos A[/tex]
[tex]a^2 = 51^2 + 45^2 -2*51*45 \cos (100^o)[/tex]
[tex]a^2 = 4626 -4590 *-0.1736[/tex]
[tex]a^2 = 4626+ 796.8[/tex]
[tex]a^2 = 5422.8240[/tex]
Take square roots
[tex]a = 73.6398[/tex]
The measure of B and C can then be calculated using sine's equation
[tex]\frac{a}{\sin A} =\frac{b}{\sin B} =\frac{c}{\sin C}[/tex]
So:
[tex]\frac{73.6398}{\sin (100)} =\frac{51}{\sin B}[/tex]
[tex]\frac{73.6398}{0.9848} =\frac{51}{\sin B}[/tex]
Cross multiply
[tex]\sin B * 73.6398 = 51 * 0.9848[/tex]
[tex]\sin B * 73.6398 = 50.2248[/tex]
Solve for sin B
[tex]\sin B = \frac{50.2248}{73.6398}[/tex]
[tex]\sin B = 0.6820[/tex]
Take arc sin of both sides
[tex]B = \sin^{-1}(0.6820)[/tex]
[tex]B = 43.0^o[/tex]
To calculate C, we make use of:
[tex]A + B + C = 180^o[/tex] --- angles in a triangle
[tex]100 + 43 + C = 180[/tex]
[tex]143 + C = 180[/tex]
Collect like terms
[tex]C =180-143[/tex]
[tex]C =37.0^o[/tex]
what times what equals -4 and adds up to 3
Answer:
-4 and 1
Step-by-step explanation:
-4 times 1 equals -4 and then -4 plus 1 equals 3
The two numbers that satisfy the given conditions are 4 and -1. They multiply to -4 and add up to 3.
To find two numbers that satisfy the given conditions, we can set up a system of equations.
Let's assume the two numbers are represented by 'x' and 'y'. We know that their product is -4 and their sum is 3, so we can write the following equations:
xy = -4 (Equation 1)
x + y = 3 (Equation 2)
To solve this system of equations, we can use the substitution or elimination method. Let's use the substitution method.
From Equation 2, we can express y in terms of x: y = 3 - x.
Substituting this into Equation 1, we get:
x(3 - x) = -4
Expanding and rearranging the equation, we have:
3x - x² = -4
Rearranging again, we get a quadratic equation:
x² - 3x - 4 = 0
We can factor this equation:
(x - 4)(x + 1) = 0
Setting each factor to zero, we find two possible solutions for x:
x - 4 = 0 --> x = 4
x + 1 = 0 --> x = -1
Now, we can substitute these values of x back into Equation 2 to find the corresponding values of y:
For x = 4: y = 3 - 4 = -1
For x = -1: y = 3 - (-1) = 4
Therefore, the two numbers that satisfy the given conditions are 4 and -1. They multiply to -4 and add up to 3.

If y varies inversely with x, and y=3 when x=16, find y when x=4
Answer:
When x =4 y=12
Step-by-step explanation:
Inverse variation is
xy = k where k is a constant
y =3 and x = 16
3*16 = k
48 = k
The equation is
xy = 48
Now let x = 4
4y = 48
Divide each side by 4
4y/4 = 48/4
y = 12
When x =4 y=12

Lena wants to replace a glass window in her restaurant. The window is in the shape of a square. Its side lengths are 7 feet. Suppose glass costs $7 for each square foot. How much will the glass cost to replace the window?
Step-by-step explanation:
It helps to draw a picture but also write what you are given
The square measures 7ft on all sides
youre paying by the square foot
to get square feet, use L x W
so 7ft x 7ft = 49 ft^2
so if we are charged $7 for 1 ft^2, then you add $7, 49 times
So youd write and solve
7 + 7 + 7 + 7 +... + 7 = $7 x 49ft^2
