1) to calculate the measurement of Unlabeled angle:
180-90-27=63°;
2) to calculate the measurement of y:
180-51-63=66°
Answer:
y= 66
the angle that the arrow is pointing to = 63
Step-by-step explanation:
you can subtract 90 by 27 to get the angle measure that the arrow is 63
we know that all of the angles in a triangle are 180
so we can add up 51 and 63 to get 114
we subtract 180 by 114 to get 66
66 degrees

help me do examples for a function and a non function
Answers
Answer:
{(1,2) (3,4) (5,6)} and {(1,2) (1,4) (5,6)}
Step-by-step explanation:
you really want to think of a function as a vending machine. if you press B12 on a vending machine because thats where the chips are, only the chips should come out. in a function, the input value aka x (B12, what youre putting in) should only have one output value aka y, (the chips)
an example of a function would be {(1,2) (3,4) (5,6)}
an important thing to remember is that one output value can belong to multiple input values. there can be chips (output) in both B12 and C12 (inputs) BUT as i said before, there CANNOT be two outputs for one input. B12 cannot give you both chips and a drink.
using this, another example of a function would be {(1,2) (3,2) (5,2)}
an example of an non function would be {(1,2) (1,4) (5,6)} because x, the input value, has multiple output values which is not possible. the output of 1 can not be 2 and 4 at the same time which we can see in the (x,y) coordinates.

Step-by-step explanation:
The area fo a circle is pi x Radius to the power of 2. 20 ft is the radius and 20x20= 400. 400 x Pi = 1,256.6370614359. The house takes up 1/4 of the whole area so 1,256... ÷ 4 = 314.159265359. This is the value of 1/4 of the area so times 314... times 3 to get 3/4ths of the area. 942.4777960769

2) b = 14.14 (nearest hundredth)

Sine Rule
[tex]\sf \dfrac{a}{\sin A}=\dfrac{b}{\sin B}=\dfrac{c}{\sin C}[/tex]
(where A, B and C are the angles and a, b and c are the sides opposite the angles)
Question 1
The interior angles of a triangle sum to 180°
⇒ m∠B = 180° - 90° - 55° = 35°
Given:
A = 55°B = 35°C = 90°c = 20[tex]\implies \sf \dfrac{a}{\sin 55}=\dfrac{b}{\sin 35}=\dfrac{20}{\sin 90}[/tex]
[tex]\implies \sf a=\dfrac{20\sin 55}{\sin 90}=16.38304089...[/tex]

Question 2
The interior angles of a triangle sum to 180°

Given:
A = 23°B = 67°C = 90°a = 6[tex]\implies \sf \dfrac{6}{\sin 23}=\dfrac{b}{\sin 67}=\dfrac{c}{\sin 90}[/tex]

To find the quadrent a coordinate pair is in:
1. look at the "x" value in the (x,y) pair
2. if its negetive go leftward and if its positive go rightward
3. once you have moved to the respective x location do the same thing with the y coordinate in the (x,y) pair
4. up is positive for y and down is negitive.
for example (3,3) would be 3 to the right and 3 up so its in the top right quadrent
(-3,-3) would be 3 left and 3 down so its in the bottom left
What is the solution to this inequality?
−4x − 8 > −20
Question 7 options:
x > −3
x < −3
x > 3
x <3
Answers
Answer:
[tex]\boxed{\sf{D. \quad x < 3}}[/tex]Step-by-step explanation:
It is necessary to isolate the term of x from one side of an inequality to find its solution.
-4x-8>-20First, add by 8 from both sides.
[tex]\sf{-4x-8+8 > -20+8}[/tex]
Solve.
-20+8=-12
Rewrite the problem down.
[tex]\sf{-4x > -12}[/tex]
Multiply by -1 from both sides.
(-4x)(-1)<(-12)(-1)
Solve.
Multiply the numbers from left to right.
(-12)(-1)=12
4x<12
Divide by 4 from both sides.
4x/4<12/4
Solve.
Divide the numbers from left to right.
12/4=3
x<3
Therefore, the correct answer is D. x<3 (last option).I hope this helps you! Let me know if my answer is wrong or not.

Answer:
Reflected along x axis
Translated 7 units to the right
A transformation of a point is the movement of the point from its initial position to a new position. If an object is transformed, all its points are also transformed. Types of transformation are reflection, rotation, dilation and translation.
Figure ABCD has A at (- 4, 4), B at (- 2, 2), C at (- 2, - 1), D at (- 4, 1).
If a point (x, y) is reflected along the x axis, its x coordinate remains the same and the y coordinate is opposite (negated). The new point is at (x, -y)
If a point (x, y) is translated h units to the right, the new coordinate is (x+h, y).The transformation are as follows:
It is reflected along the x axis so that the new coordinates would be at A1 at (- 4, -4), B1 at (- 2, -2), C1 at (- 2, 1), D1 at (- 4, -1)
It is translated 7 units to the right, The new coordinates are A' at (3, -4), B' at (5, -2), C' at (5, 1), D' at (3, -1)

Then we can solve for x.
Combine like terms:
4x+20=180
4x+20-20=180-20
4x=160
4x/4=160/4
x=40
Now we plug in 40 for x.

4003.595 ÷ 160 ≈ 25.02

A store is giving out cards labeled 1 through 10 when customers enter the store. If the card is an even number, you get a 15% discount on your purchase that day. If the card is an odd number greater than 6, you get a 30% discount. Otherwise, you get a 20% discount. The table shows the results of 400 customers. What is the relative frequency for each discount? If the manager of the store wants approximately half of the customers to receive the 20% discount, does this seem like an appropriate method? Explain.
Answers
Answer:
No
Step-by-step explanation:
It is not an appropriate method because if you add all of the people that got 1, 3, and 5 together to get all the people that got the 20% discount, you get 140/400 people, and in order for it to be half there would have to be, or close enough to, a total of 200/400 people.
15% discount = 185/400 or 46.25%
20% discount = 140/400 or 35%
30% discount = 75/400 or 18.75%
