I'm going to also give you how to get the answer... not just the answer.. you will need to know this for a test :/ so learn it :P
Step-by-step explanation:
Sin(30)=12
to remember what Sin and Cos at those speacial angles in degrees are.. just use this Sin(degrees)
Sin(0) = 0/2 =0
Sin(30)= [tex]\sqrt{1}[/tex]/2 = 1/2
Sing(45) = [tex]\sqrt{2}[/tex]/2 = [tex]\sqrt{2}[/tex]/2
Sin(60)=[tex]\sqrt{3}[/tex]/2 = [tex]\sqrt{3}[/tex]/2
Sin(90)=[tex]\sqrt{4}[/tex]/2 = 1
Cos is exactly the same but counts backwards from 90°
Cos(90) = 0/2 =0
Cos(60) = [tex]\sqrt{1}[/tex]/2 = 1/2
Cos(45) = [tex]\sqrt{2}[/tex]/2 = [tex]\sqrt{2}[/tex]/2
Cos(30) = [tex]\sqrt{3}[/tex]/2 = [tex]\sqrt{3}[/tex]/2
Cos(0) =[tex]\sqrt{4}[/tex]/2 = 1
note that the numerators just count from 0,1,2,3,4 , see? you can remember sin and cos now :) since you can count to 4 :P
Sin(30) =12
1/2 =12 while that statement makes no sense.... obviously 1/2 isn't equal to 12 but.. what's being said is that the angle of 30° gives you a side that is 12 units long.
so looking at what I wrote above.. which angle in degrees matches Sin when you look at Cos?
Sin(30)= 1/2 and Cos(60) also = 1/2 huh
sooo β = 60 °
got it? :/

What function is graphed below?
Y=x/3
Y=2 x +3
Y= 2 x + 3
Y = 3x
Answer: its y=x/3
So x/3 is the slope and means the same as 1/3 x
the 1/3 shows we go up one and over 3 because slope is y/x

Step-by-step explanation:
You can create point c at (3,4) to make a right triangle
Then you know that the 2 legs are 6 and 8
We need to find the hypotenuse
You can use pythagorean theorem:
6^2+8^2=c^2
So c=10
So the distance is 10 units

The mean of six numbers is 14. If one of the six numbers is removed, the mean becomes 5. What is the value of the number removed?
Answer:
Remember, the mean is calculated by adding the scores together and then dividing by the number of scores you added. In this case, the mean would be 2 + 4 (add the two middle numbers), which equals 6. Then, you take 6 and divide it by 2 (the total number of scores you added together), which equals 3.
Step-by-step explanation:
Hope I helped.It's just a reminder of helpful things for means!
Answer:
59
Step-by-step explanation:
Suppose a, b, c, d, e and f represent the 6 numbers.
Then, [tex]\frac{a + b + c + d + e + f}{6} = 14\\[/tex]
(1) a + b + c + d + e + f = 84
Let's remove f
then [tex]\frac{a + b + c + d + e}{5} = 5[/tex]
(2) a + b + c + d +e = 25
Substitute 25 in for a + b + c + d +e in equation (1)
We have 25 + f = 84
f = 59

A basketball player scores 28 points in
a game. She scores 35% of the total
team points.
How many points does her team score in
total?
a 63
b 65
C 72
d 80
Answer:
d) 80
Step-by-step explanation:
(35% = 0.35)
equation:
⇒ [tex]0.35x = 28[/tex]
divide 0.35 on both sides
⇒ [tex]\frac{0.35x}{0.35} = \frac{28}{0.35}[/tex]
solve:
⇒ x = 80
The total number of points will be 80. The correct option is D.
What is an expression?In mathematics, expression is defined as the relationship of numbers, variables, and functions using mathematical signs such as addition, subtraction, multiplication, and division.
Assume a basketball player scores 28 points per game. She accounts for 35% of the team's total points.
Calculate the number of the points below,
35% of x = 28 points
x = ( 28 x 100 ) / 35
x = 80 points
Therefore, the number of points will be 80. Option D will be the right answer.

This composite figure is created by placing a sector of a circle on a rectangle. What is the area of this
composite figure? Use 3.14 for it. Show all calculations that lead to the answer and include units. Please provide steps to prove your answer.
Answer:
148.12m²
Step-by-step explanation:
At first, lets find the area of rectangle.
length = 14m
breadth = 6m
Area of rectangle = length x breadth
= 14 x 6
= 84m²
Now, For the area of sector of the circle,
Given angle (a) = 34
radius = 14m
Area of the sector = a / 360 x pi x r²
= 34/360 x 3.14 x 14²
= 34 / 360 x 3.14 x 196
= 58.12m²
Now adding both areas,
84 + 58.12 = 142.12m²
Segment of a circle is the part of the circle. The total area of the composite figure is 142.1544 m².
What is the area of the segment of a circle?The area of the segment of the circle is given by the formula,
[tex]\rm \text{Area of the rectangle} = \pi r^2 \times \dfrac{\theta}{360}[/tex]
As it is given that the composite figure is made up of a circular segment and a rectangle, therefore, we will find the area of the rectangle and the area of the circular segment individually.
Area of the rectangle
The area of the rectangle is the product of its length and breadth, therefore, the area is,
[tex]\rm \text{Area of the rectangle} = Length \times breadth[/tex]
[tex]= 14 \times 6\\\\=84\rm\ m^2[/tex]
Area of the sector of the circle
[tex]\rm \text{Area of the rectangle} = \pi r^2 \times \dfrac{\theta}{360}[/tex]
[tex]= \pi \times 14^2 \times \dfrac{34}{360}\\\\=58.1544\rm\ m^2[/tex]
The total area of the composite figure
The total area of the composite figure
= Area of rectangle + Area of the segment of the circle
= 84 + 58.1544 m²
= 142.1544 m²
Hence, the total area of the composite figure is 142.1544 m².
