Answer:
B) -1/2
C) {30, 150}
Step-by-step explanation:
Question 3)
We can see that the angle equals 210* which equals 7pi/6 (in radians)
The coordinates would be [tex](\frac{-\sqrt{3} }{2}, \frac{-1}{2})[/tex]
Since the problem is asking for sinθ, we will use -1/2 (the y-coordinate)
So the answer is B) -1/2..
Question 4)
If the criteria of the answer is that it must be between 0 < θ < 360 and it must have a y-value of 1/2 in its coordinate (sinθ = 1/2), then we will choose angles that meet this criteria. When we look at the unit circle (see the attached) we can see that only the angles of 30* and 150* match this answer, so our answer is c.

The slope of the graph of machine 1 is: 1/2
The slope of the graph of machine 2 is: 4/5
Step-by-step explanation:
Machine 1
Machine 1 Table is given by
Time (sec) 1 2 3 4
Amount (gal) 0.5 1 1.5 2
Taking two points
(1, 0.5)(2, 1)Determining the slope between any two points (1, 0.5) and (2, 1)
[tex]\left(x_1,\:y_1\right)=\left(1,\:0.5\right),\:\left(x_2,\:y_2\right)=\left(2,\:1\right)[/tex]
[tex]m=\frac{1-0.5}{2-1}[/tex]
[tex]m=0.5[/tex]
[tex]m = 1/2[/tex]
Therefore, the slope of the graph of machine 1 is: 1/2
Machine 2
Taking two points from the graph of Machine 2
(0, 0)(10, 8)Determining the between any two points (0, 0) and (10, 8)
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(0,\:0\right),\:\left(x_2,\:y_2\right)=\left(10,\:8\right)[/tex]
[tex]m=\frac{8-0}{10-0}[/tex]
[tex]m=\frac{4}{5}[/tex]
Therefore, the slope of the graph of machine 2 is: 4/5

what is 39% as a fraction in its lowest form
Answers
39% as a fraction in its lowest form is 39/100.
To express 39% as a fraction in its lowest form, we need to divide the percentage by 100 and simplify the resulting fraction.
The percentage symbol "%" means "per hundred," so 39% can be written as 39/100.
To simplify this fraction, we can divide both the numerator and denominator by their greatest common divisor (GCD).
Here, the GCD of 39 and 100 is 1, so we divide both numbers by 1:
= 39 ÷ 1 / 100 ÷ 1
= 39/100
Therefore, 39% as a fraction in its lowest form is 39/100.

Which two figures on the grid below have the same area?
W
Х
Y
Z
O Wand X
O Y and Z
O Wand Z
O X and Y
HELPP
Answers
Answer:
X and Y
Step-by-step explanation:
Right triangle: a = 1/2bh
Rectangle: a = lw
Circle: a = pi*r^2
1/2*2*3 = 3
2*3 = 6
pi(1.5^2) = 7.069
Sqrt2^2 = 2
Sqrt2*2Sqrt2 = 4
2+4 = 6
figure "X" and the figure "Y" have the same amount of area.
What is Area?Area is the entire amount of space occupied by a flat (2-D) surface or an object's form. On a sheet of paper, draw a square using a pencil. It has two dimensions. The area of a form on paper is the area that it occupies.
Given four figures to find the which two figures have the same area.
To calculate the area consider these mini squares to be unit squares.
For the first figure,
area of triangle = 1 /2 * base * height
In our case,
base = 2 unit
height = 3 units
Thus, area = 1/2 * 3 * 2
Area = 3 unit square
For second figure,
area of rectangle = base * height
in our case,
base = 3
height = 2
thus,
area = 3 * 2 = 6 unit squares
For the third figure,
We will separate it into two figures one is rectangle of √2 and 2√2 sides and the other is a square of √2 side.
(Since, diagonal of the Unit square is √2 from the Pythagorean theorem)
Thus,
Area of the "Y" figure = √2 * 2 √2 + (√2)²
Area of the "Y" figure = 4 + 2
Area of the "Y" figure = 6 unit square
For the fourth figure,
Area of circle = pi * radius²
In our case,
radius = 1.5 unit
Thus,
Area = pi * 1.5*1.5
Area = 7.68 unit square
Therefore, figure "X" and the figure "Y" have the same amount of area.

The width of a rectanle is 8n - 8.5 feet and the lenght is 8.5n + 10 feet. Find the perimeter of the rectangle
Answers
Answer:
The perimeter of a rectangle is:
P = 33n+3Step-by-step explanation:
Given
The width of a rectangle w = 8n - 8.5 feet
The length of a rectangle l = 8.5n + 10 feet
To determine
The perimeter of a rectangle = P = ?
The perimeter of a rectangle can be determined using the formula
[tex]P = 2(l+w)[/tex]
substitute l = 8.5n + 10 and w = 8n - 8.5
[tex]P=2\left(8.5n+10+8n-8.5\right)[/tex]
[tex]=2\left(16.5n+10-8.5\right)[/tex]
[tex]=2\left(16.5n+1.5\right)[/tex]

Regan's New Year's resolution is to exercise more. Today, she plans to run 1.5 miles on the track around her school's football field. If each lap around the track is 0.25 miles, how many laps should she run?
Answers
Answer:
6 laps
Step-by-step explanation:
According to the scenario, calculation of the data are as follows:
Each lap = 0.25 miles
Regan's plan to run= 1.5 miles
So, we can calculate number of laps by using following formula,
Number of laps = Total miles to run ÷ each lap miles
By putting the value, we get
Number of laps = 1.5 miles ÷ 0.25 miles
= 6 laps
So, she should run 6 laps.
