Which of the following is true of the location of the terminal side of an angle 0 who's sine value is 1/2?- has a reference angle of 30° and is in quadrant one or two- as a reference angle 30° and is in quadrant one or four- has a reference angle of 60° and is in quadrant one or two- as a reference angle of 60° in is in quadrant one or four
Answers
Out of the following the statement has a reference angle of 30° and is in quadrant one or two- is true of the location of the terminal side of an angle 0 whose sine value is 1/2.
Since the reason behind this is that the sine value of 1/2 can be written as sin(30°), this means that the terminal side of the angle is located at 30°, which is either quadrant one or two. Quadrant one is the upper right quadrant of the coordinate plane, and quadrant two is the upper left quadrant.
The reference angle of an angle is the angle between the terminal side of the angle and the positive x-axis. In this case, the reference angle would be 30°. The reference angle of an angle is important because it is used to determine the quadrant in which the terminal side of the angle is used to determine the quadrant in which the terminal side of the angle is located. The reference angle must be less than 90° in order for the terminal side to be located in the first and second quadrants.

The perimeter of a pool is 150 m. the rectangle at the right is a scale drawing of the pool. The length of each square on the grid represents 1 cm. draw another scale drawing of the pool using the scale 25 m to 2 cm. Explain why your drawing is accurate.
Answers
The dimensions of the another rectangle is 2 cm and 4 cm.
According to the statement
We have to find that the perimeter of another rectangle.
So, For this purpose, we know that the
The perimeter of a shape is defined as the total length of its boundary.
From the given information:
The perimeter of a pool is 150 m. the rectangle at the right is a scale drawing of the pool. The length of each square on the grid represents 1 cm. draw another scale drawing of the pool using the scale 25 m to 2 cm.
Then
From the given rectangle,
Length of the rectangle = 5 cm
Width of the rectangle = 10 cm
Ratio of length : width = 1 : 2
Perimeter of the rectangle = 2(l + b)= 150 cm
l + b = 75 -----(1)
Since, l : b = 1 : 2
l/b = 1/2
b = 2l ------(2)
From equations (1) and (2),
l + 2l = 75
3l = 75
l = 25 m
Width 'b' = 2(25) = 50 m
Now we've to draw a rectangle with a scale = 25 : 2
Therefore, multiplier factor = 25/l = 25/2
l = 2 cm
Similarly,
50/w = 25/2
w = 4 cm
Now we are able to draw a rectangle with length = 2 cm and width = 4 cm.
So, The dimensions of the another rectangle is 2 cm and 4 cm.

The line represented by 4y = 2x + 12 is dilated by a scale factor of k centered at the origin, such that the image of the line has an equation of y = (1/2)x + 30. What is the scale factor?
Answers
Answer:
10
Step-by-step explanation:
4y = 2x + 12
Divide both sides by 4:
y = ½ x + 3
This has a slope of ½ and a y-intercept of 3.
The other line has the same slope and a y-intercept of 30.
So the scale factor is 10.

Answers
The ordered pair which s included in the solution to this system of inequality y ≥ 2/3x + 2, y < - 1/3x + 1 is (-6, -2) and (-6, 3).
The correct answer option is option B and C
How to solve the system of inequality?y ≥ 2/3x + 2
y < - 1/3x + 1
Check all that applies:
(x, y) = (−6, −3)
(x, y) = (−6, −2)
(x, y) = (−6, 3)
(x, y) = (−6, 4)
It can be seen that x = -6Use this to find the value of yy ≥ 2/3x + 2
substitute x = -6 into the inequality
y ≥ 2/3(-6) + 2
y ≥ -12/3 + 2
y ≥ - 4 + 2
y ≥ - 2
(x, y) = (-6, -2)
y < - 1/3x + 1
substitute x = -6 into the inequality
y < -1/3(-6) + 1
y < 6/3 + 1
y < 2 + 1
y < 3
(x, y) = (-6, 3)
So therefore, the solution to the system of inequality is (-6, -2) and (-6, 3).

A man, a woman, and their four children randomly stand in a row for a family picture. What is the probability that the parents will be standing next to each other?
Answers
Answer:
Required probability = 2 / 11
Step-by-step explanation:
Sample space of 5 person = 11!
One woman one man arrangement = 2!
Arrangement without woman = 10!
Required probability = [2!][10!] / [11!]
Required probability = 2 / 11
The probability that the parents will be standing next to each other is 2/11
Probability is the likelihood or chance that an event will occur.
Probability = Expected outcome/Sample spaceGiven a woman, man and their four children, if their parents will be standing next to each other, that makes it 5 people. The sample space for 5 people is 11!
The parent arrangement is 2!If they are arranged without the woman, the expected event will be 10!Pr(parents standing next to each other) = 2!10!/11!
Pr(parents standing next to each other) = 2*10!/11*10!
Pr(parents standing next to each other) = 2/11
Therefore the probability that the parents will be standing next to each other is 2/11

(c) In how many way we can list the digits{1,1,2,2,3,4,5}so that notwo identical digit are in consecutive positions?
Answers
Answer:
660 ways
Step-by-step explanation:
we have two numbers in consecutive positions in this question
(1,1) and (2,2)
numbers of ways that (1,1) are in consecutive positions = 6!/2! = 360
number of ways that (2,2) are in consecutive positions = 6!/2! = 360
the permutation of (11),(22),3,4,5 = 5!
ps: I counted the pairs as one each.
5! = 120
to get total number of permutations
7!/2!2!
= 5040/4
= 1260
the number of ways that 2 identical digits are not consecutively positioned = 1260-360-360+120
= 660 ways
