Given the diagram below, what is sin (30°) ?
Answer:
A. 1/2.
Step-by-step explanation:
The ratio of the sides of a 30-60-90 triangle is 2:1:√3 where 2 is the hypotenuse. 1 is the shortest leg and √3 is the longest leg.
In the diagram we see that the longest leg is opposite the 60 degree angle.
So the longest leg is 3.5√x and the shortest leg ( from applying the ratios) = 3.5√x / √3.
and the hypotenuse is 2 * 3.5√x / √3 (using the ratios again).
So sin 30 = shortest leg / hypotenuse = 3.5√x / √3 / 2 * 3.5√x / √3
= 1/2.

C. [tex]4\sqrt{5}[/tex]
D. [tex]5\sqrt{4}[/tex]
Answer:
8√5 units.
Step-by-step explanation:
See the diagram in the coordinate plane attached.
A rhombus has four equal sides and to find the perimeter of the rhombus we have to measure any of the sides of the figure of the rhombus.
The coordinates of the topmost point are (-1,-1) and that of the rightmost point are (3,-3).
Therefore, side length of the rhombus will be
[tex]\sqrt{(- 1 - 3)^{2} + (- 1 - (- 3))^{2}} = \sqrt{20} = 2\sqrt{5}[/tex] units.
So, the perimeter of the rhombus will be (4 × 2√5) units = 8√5 units. (Answer)
The distance between two points [tex](x_{1},y_{1})[/tex] and [tex](x_{2},y_{2})[/tex] on a coordinate plane is given by

the cone's base is 5 centimeters, and its height is 10 centimeters.
The number of times one needs to use the completely filled cone to completely fill the cylinder with water is
Reset
Next
Answer: 24times
Step-by-step explanation:
Formula for the volume of a cylinder = πr²h
Volume of the cone = 1/3πr²h
Therefore the volume of the cylinder = 22/7 x 10² x 20
= 22/7 x 10 x 10 x 20
= 6285.71cm³
Therefore , the volume of the cone = 1/3 x 22/7 x 5² x 10
= 1/3 x 22/7 x 5 x 5 10
= 5500/21
= 261.9cm³
Therefore the number of times needed to use the completely filled cone to completely filled the cylinder with water = 6285.71/261.9
= 24times.

11. If line a is parallel to line b, solve for x:
(7x + 11)
(10x - 43)
To find the value of x for parallel lines with expressions (7x + 11) and (10x - 43), set them equal and solve the resulting equation, which gives x = 18.
If line a is parallel to line b and we have the expressions (7x + 11) for line a and (10x - 43) for line b, then the corresponding angles formed by these lines and a transversal would be equal. To solve for x, we set the two expressions equal to each other because the slopes of parallel lines are equal. The equation would be 7x + 11 = 10x - 43.
Subtract 7x from both sides: 11 = 3x - 43.Add 43 to both sides: 54 = 3x.Divide both sides by 3: x = 54 / 3.Therefore, x = 18.This is the value of x that makes the two expressions equal, thus confirming the lines are parallel.
There are 100 freshman students at a school. The probability that a freshman plays a sport is 0.55. The probability that a freshman plays a musical instrument is 0.34. The probability that a freshman plays both a sport and a musical instrument is 0.15. What is the probability that a freshman student at this school plays either a sport or a musical instrument?
The probability that a freshman student at this school plays either a sport or a musical instrument is 0.74
Step-by-step explanation:
The addition rules in probability are:
P(A or B) = P(A) + P(B) ⇒ mutually exclusive (events cannot happen at the same time)P(A or B) = P(A) + P(B) - P(A and B) ⇒ non-mutually exclusive (if they have at least one outcome in common)∵ The probability that a freshman plays a sport is 0.55
∴ P(sport) = 0.55
∵ The probability that a freshman plays a musical instrument is 0.34
∴ P(music) = 0.34
∵ The probability that a freshman plays both a sport and a musical
instrument is 0.15
∴ P(sport and music) = 0.15
To find the probability that freshman student at this school plays either a sport or a musical instrument use the second rule above because it is non-mutually exclusive
∵ P(sport or music) = P(sport) + P(music) - P(sport and music)
∴ P(sport or music) = 0.55 + 0.34 - 0.15
∴ P(sport or music) = 0.74
The probability that a freshman student at this school plays either a sport or a musical instrument is 0.74

The probability that a freshman student at this school plays either a sport or a musical instrument is indeed 0.74
To find the probability that a freshman student plays either a sport or a musical instrument, we can use the principle of inclusion-exclusion for probability.
The principle states that for any two events A and B, the probability of the union of A and B is given by:
[tex]\[ P(A \cup B) = P(A) + P(B) - P(A \cap B) \][/tex]
Let event A be the event that a freshman plays a sport, and event B be the event that a freshman plays a musical instrument.
We are given the following probabilities:
P(A) = 0.55 (the probability that a freshman plays a sport)
P(B) = 0.34 (the probability that a freshman plays a musical instrument)
P(A and B) = 0.15 (the probability that a freshman plays both a sport and a musical instrument)
Using the principle of inclusion-exclusion, we calculate the probability Upon reviewing the calculation, it appears there was an error in the final step.
The correct calculation should be:
[tex]\[ P(\text{either A or B}) = P(A \cup B) \][/tex]
[tex]\[ P(\text{either A or B}) = 0.74 \][/tex]
Therefore, the probability that a freshman student at this school plays either a sport or a musical instrument is indeed 0.74, not 0.64 as initially stated.
The final answer is [tex]\(\boxed{0.74}\).[/tex]

Otto's investment portfolio consisted of shares of internet stock and copper stock. During the year, the value of his internet shares increased $10\%$, but the value of his copper shares decreased from $\$10{,}000$ to $\$9{,}000$. During the same year, the total value of his portfolio increased by $6\%$. What was the dollar value of his internet shares at the end of the year?
Answer:
44000
Step-by-step explanation:
Let w be the initial value of Otto's internet stock, in dollars. At the beginning of the year, the total value of his portfolio is w+10,000 dollars. At the end of the year, the total value of his portfolio is 1.1w+9,000 dollars. Since increasing by 6% is equivalent to multiplying by 1.06, we have
1.06(w+10,000)=1.1w +9,000
Distributing and collecting terms, we find w=40,000. At the end of the year, his internet stock is worth 40,000* 1.1=44,000 dollars.

During the summer, Jody earns $10 per hour babysitting and $15 per hour doing yardwork. This week she worked 34 hours and earned $410.
If x represents the number hours she babysat and y represents the number of hours she did yardwork, which system of equations models
this situation?
A.
X+ y = 34
10x+ 15y = 410
OB. X + y = 410
10x + 15y = 34
C.
X+ y = 34
15x+10y= 410
OD. x + y = 410
15x+10y = 34
Answer:
A
Step-by-step explanation:
x+y=34 (add the seperate hours together to get the total amount of hours)
10x+15y=410 (multiply the money made each hour by the hours worked and add them together to get the amount of money joy made)
The system which creates a mathematical representation of the given condition will be X+ y = 34 and 10x+ 15y = 410 so option (A) will be correct.
How to form an equation?When trying to set up or construct a linear equation to fit a real-world application, identify the known quantities and use the unknown quantity as a variable.
In other words, an equation is a set of variables that are constrained through a situation or case.
x = number of hours babysitting.
y = number of hours yard work.
Given that
She worked a total of 34 hours
So x + y = 34 will be the correct formation.
Jody earns $10 per hour babysitting
So a total of 10x money Jody will earn through babysitting.
$15 per hour doing yardwork
So a total of 15x money Jody will earn through yard work.
Given that
A total of $410 Jody earned so
10x + 15y = 410 will be the correct formation.

Every student in the senior class is taking history or science. There are $200$ seniors in the class. If there are $126$ seniors taking history and $129$ seniors taking science, how many students are taking both history and science?
Answer: 55
Step-by-step explanation:
126+129= 255
255-200=55
55 students are taking both history and science.
To solve this, we set up the problem as follows: Let H represent the set of students taking history, S represent the set of students taking science, and N represent the total number of seniors. We're given that N = 200, |H| = 126 (the number of students taking history), and |S| = 129 (the number of students taking science). The number of students taking both can be found by adding the number of students in sets H and S and subtracting the total N. This calculation is often represented by the formula |H ∩ S| = |H| + |S| - N, where |H ∩ S| is the number of students taking both history and science.
Using the formula, we calculate: |H ∩ S| = 126 + 129 - 200 = 55. Therefore, 55 seniors are taking both history and science.

Elyse has $18 on a gift card that she can use to rent movies online. The graph at the right shows the amount of money remaining on her gift card ba. sed on the number of movies she rents. Find the unit rate of the graph, and describe what it means in the context of the situation.
Answer:
see the explanation
Step-by-step explanation:
The complete question in the attached figure
Let
x ----> the number of movies
y ----> the amount of money remaining on her gift card
we know that
The slope of the linear equation is equal to the unit rate
take two points from the graph
(0,18) and (2,12)
Find the slope
[tex]m=(12-18)/(2-0)[/tex]
[tex]m=(-6)/(2)=-\$3\ per\ movie[/tex] ---> is negative because is a decreasing function
That means -----> Each movie she rents cost her $3, so her gift card balance will decrease $3 for every movie rented
The linear equation is equal to
[tex]y=-3x+18[/tex]
For y=0
[tex]0=-3x+18[/tex]
[tex]x=6[/tex]
so
6 is the maximum number of movies that Elyse can rent on line
The unit rate is the ratio of the change in the y-coordinate value to the change in the x-coordinate value between any two strategically chosen points. Elyse's unit rate represents the cost per movie rental.
Explanation:While the graph isn't directly available, the principle to find the unit rate of the graph is the same. The unit rate is the ratio of the change in the vertical (y-axis) value to the change in the horizontal (x-axis) value between any two distinct points on the graph. In the context of Elyse's movie rentals, the unit rate would represent the cost per movie.
To calculate this, you'd subtract the y-coordinate value of the second point from the y-coordinate value of the first point. This represents the change in the balance of the gift card. Then you'd subtract the x-coordinate value of the second point from the x-coordinate value of the first point, representing the number of movies rented. Dividing the change in balance by the number of movies gives the cost per movie, which is our unit rate.
For example, if she had $12 after renting 2 movies and $6 on her card after renting 4 movies, the unit rate would be computed as: (12 - 6) / (4 - 2) = $3 per movie. This means that for every movie that Elyse rents, she spends $3 from her gift card.
