An investor has an account with stock from two different companies. Last year, his stock in Company A was worth $5900 and his stock in Company B was worth $1850. The stock in Company A has increased 20% since last year and the stock in Company B has increased 18%. What was the total percentage increase in the investor's stock account? Round your answer to the nearest tenth (if necessary).
Answer:
Step-by-step explanation:
Final Answer: 19.5%
The total percentage 19.5% increase in the investor's stock account
What is a percentage?A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.
Given:
An investor has an account with stock from two different companies. Last year, his stock in Company A was worth $5900 and his stock in Company B was worth $1850.
The total worth is $5900 + $1850 = $7750
The stock in Company A has increased 20% since last year.
So,
20% of 5900,
= 20 x 5900 /100
= $1180
And the stock in Company B has increased 18%.
So,
18% of 1850,
= 18 x 1850/100
= $333
The total increased amount,
= $333 + $1180
= $1513
The increased percentage,
1513 = n x 7750/100
n = 1513 x 100/7750
n = 19.522
n = 19.5% to the nearest tenth.
Therefore, 19.5% is the required percentage.

A right angle intersects a line at point M.
A right angle intersects a vertical line at point M and forms 3 angles. From top to bottom going clockwise, the angles are 1, 90 degrees, 2.
Which statement is true about angles 1 and 2?
They are congruent.
They are right angles.
They are complementary.
They are supplementary.
Answer:
I've attached an image showing the intersection and the angle.
Answer:
C: They are complementary
Step-by-step explanation:
We can see from the image that angle 1, angle 2 and 90° are on a straight line. We know that sum of angles on a straight line is 180°. Thus;
∠1 + ∠2 + 90° = 180°
Rearranging, we have;
∠1 + ∠2 = 180° - 90°
Thus;
∠1 + ∠2 = 90°
Now, from angle proofs in trigonometry, it states that If the non-common sides of two adjacent angles add up to 90°, then it means that the angles are complementary.
In our problem here, sum of ∠1 and ∠2 equals 90°. Also, they are the non-common sides of 2 adjacent angles. Thus, we can say that they are complementary.

Step-by-step explanation:
A manager drew this box-and-whisker plot to represent the number of minutes each of the company's 360 employees took on their break.
Box-and-whisker plot ranging from 34 to 58 with ticks at increments of one half. Plot defined by points at 35, 37, 41, 49, 55
How many employees took a break that lasted between 37 and 41 minutes?
Select from the drop-down menu to correctly complete the statement.
About (blank) employees took a break that lasted between 37 and 41 minutes.
Answer:
90
Step-by-step explanation:
37 and 41 is only in the 25% percentile.
360 X .25 = 90
Plus, I took the K12 test and got it right.
The number of employees took a break that lasted between 37 and 41 minutes is 60.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. Unitary method is a technique by which we find the value of a single unit from the value of multiple devices and the value of more than one unit from the value of a single unit. It is a method that we use for most of the calculations in math.
We know that;
There are 360 employees in total and that they are evenly distributed along this plot. Therefore, we can divide 360 by the width of this plot to find how many employees are represented by one unit on this plot. The width of this plot is 58 - 34 = 24 units.
So, 360 / 24 = 15
This means that for every unit on this plot, there are 15 employees who took a break with that duration.
Now we can multiply this number by the width of the box to find how many employees took a break between 37 and 41 minutes. The width of the box is 41 - 37 = 4 units. So,
15 * 4 = 60
This means that there are 60 employees who took a break that lasted between 37 and 41 minutes.
Therefore, by the unitary method the answer will be 60 employees

Answer:
See below for answers and explanations
Step-by-step explanation:
Problem 1
To convert from polar to Cartesian coordinates, recall that [tex](x,y)=(r\:cos\theta,r\:sin\theta)[/tex], thus, [tex](x,y)=(6\:cos\frac{5\pi}{6},6sin\frac{5\pi}{6})=(6(-\frac{\sqrt{3}}{2}),6(\frac{1}{2}))=(-3\sqrt{3},3)[/tex]
Therefore, C is the correct answer
Problem 2
Convert from polar to Cartesian coordinates:
[tex](x,y)=(-5\:cos\frac{2\pi}{3},-5\:sin\frac{2\pi}{3})=(-5(-\frac{1}{2}),-5(\frac{\sqrt{3}}{2}))=(\frac{5}{2},\frac{-5\sqrt{3}}{2})[/tex]
Therefore, U is the correct answer
Problem 3
Since [tex]r=\sqrt{x^2+y^2}[/tex], then [tex]r^2=x^2+y^2[/tex]. Don't also forget to use the substitution [tex]x=r\:cos\theta[/tex]:
[tex]x^2+y^2-7x=0\\\\r^2-7rcos\theta=0\\\\r(r-7cos\theta)=0\\\\r-7cos\theta=0\\\\r=7cos\theta[/tex]
Therefore, B is the correct answer
Problem 4
[tex]r=(tan\theta)(sec\theta)\\\\r=(\frac{sin\theta}{cos\theta})(\frac{1}{cos\theta})\\ \\\frac{r^2}{r}=(\frac{rsin\theta}{rcos\theta})(\frac{r}{rcos\theta})\\ \\\frac{x^2+y^2}{\sqrt{x^2+y^2}}=(\frac{y}{x})(\frac{\sqrt{x^2+y^2}}{x})\\ \\x^2+y^2=\frac{y(x^2+y^2)}{x^2}\\ \\1=\frac{y}{x^2}\\\\x^2=y[/tex]
Therefore, A is the correct answer

you spin the spinner, flip a coin, then spin the spinner again. find the probability of the compound event. write your answer as a fraction or percent. if necessary round your answer to the nearest hundredth.
(Spinning an odd number, flipping head, then spinning yellow)
Answer:
1/9
Step-by-step explanation:
Probability is defined as the number of cases fitting a constraint divided by the number of total cases.
We will calculate the number of total cases first (bc its easier xD):
3 numbers for the first spin times 2 cases for the flip times 3 numbers for the first spin = 18 total cases.
Now, we will calculate the number of cases fitting the constraint:
For the first constraint, there are two possible ways of spinning an odd number, landing on 1 or 3.
For the second constraint there is only 1 way, which is spinning a head.
For the 3rd constraint, there is only 1 way to spin yellow.
2 * 1 * 1 = 2
Number of cases over total cases:
2/18 = 1/9
Step-by-step explanation:
we seek the probability of a combination of independent events.
since they are independent, we can simply multiply the 3 individual probabilities.
1. spin an odd number (in our case that means 1 or 3) out of the possible 3. that probabilty is therefore 2/3.
2. flipping head with a coin. so, 1 out of possible 2. that probabilty is therefore 1/2
3. spin yellow. that is 1 out of possible 3. that probabilty is therefore 1/3.
again, none of the single events is influencing the outcome of any of the other 2 events, so, the total probabilty of the combination is the product of the single probabilities :
2/3 × 1/2 × 1/3 = 2/18 = 1/9
FYI : the first single probabilty is actually the result of an "or" relationship of 2 possible results of one event :
the probabilty to get an odd number is the same as the probabilty to get 1 or to get 3. both are non-overlapping possible outcomes of one event, so we can add the individual probabilities for the result.
each possible outcome has the probabilty of 1/3, so the "or" relation has a probabilty of 1/3 + 1/3 = 2/3.
Solve completely (all missing sides and all missing angles) using trig ratios or laws. Round to the nearest tenth.
Answer:
Step-by-step explanation:
3. Use Cosine law to find the length of the unknown side (PR)
q² = p² + r² - 2prCos Q
q is the opposite side of ∠Q;
p is the opposite side of ∠P; p = 33
r is the opposite sides of ∠R ; r = 67
q² = 33² + 67² - 2* 33*67 Cos 19°
= 1089 + 4489 - 4422 * 0.95
= 1089 + 4489 - 4200.9
= 1377.1
q = √1377.1
q = 37.1
PR = 37.1
To find the angle use law of sin
[tex]\sf \dfrac{q}{Sin \ Q} =\dfrac{p}{Sin \ P}\\\\\\\dfrac{37.1}{Sin \ 19}=\dfrac{33}{Sin \ P} \\\\\\\dfrac{37.1}{0.33}=\dfrac{33}{Sin \ P}\\\\\\37.1* Sin \ P = 33 *0.33\\\\Sin \ P =\dfrac{33*0.33}{37.1}[/tex]
Sin P = 0.3
[tex]P = Sin^{-1} 0.3\\[/tex]
P = 17.5°
∠R = 180 - (19 + 17.5)
