find the value of 0 round to the nearest whole degree
Answer:
27°
Step-by-step explanation:
we have the 'opposite' as length 2 is opposite the angle θ
we have the adjacent (length 4) which is next to the angle θ
the hypotenuse is the longest side (we don't need)
Using SOHCAHTOA
we use TOA as O is opposite and A is adjacent
tanθ = opposite ÷ adjacent
tanθ = 2 ÷ 4
using the inverse sign to find θ
θ = tan⁻¹(2/4) = 27° (to the nearest whole degree)

Answer:
[tex]\huge\boxed{\sf{\displaystyle\frac{2}{15}}}[/tex]
Step-by-step explanation:
Hello.
In order to solve for c, we need to take the square root of both sides.
What is the square root?
It's the opposite of squaring.
Here, c is squared (multiplied by itself) so in order to isolate it, we need to take the square root of both sides.
Remember the Golden Rule of Algebra:
Whatever we do to one side, we do to the other.
Take the square root:
[tex]\sf{\sqrt{c^2}=\sqrt{\displaystyle\frac{4}{225}[/tex]
[tex]\sf{c=\displaystyle\frac{2}{15}[/tex]
I hope it helps.

Answer:
See below.
Step-by-step explanation:
For a rational function, the equation is [tex]\displaystyle \large{f(x)=\frac{a}{b(x-c)}+d}[/tex] where:-
c is horizontal shift.d is vertical shift.a/b determines how wide or narrow the graph is.x = c is a vertical asymptote.y = d is a horizontal asymptote.We are given a function [tex]\displaystyle \large{f(x)=\frac{1}{x}-1}[/tex] . Examine the function, we know that:-
.The graph has no horizontal shift as c = 0.The graph has the vertical shift which is -1. Therefore d = -1x = 0 is our vertical asymptote.y = -1 is our horizontal asymptote.Additional Info
- Asymptote line is a line that the graph tends to approach but never intersects.
From the information we have, first - draw both vertical asymptote and horizontal asymptote to make it easier to draw a graph.
Then draw a rational function’s graph as it tends to 0 when x = 0 and -1 when x tends to both sides of infinity.
You should receive a graph below that I made, see the attachment. The purple line represents the horizontal asymptote and y-axis is our vertical asymptote.

You and your friend are going into business mowing lawns. If you can mow a 1 acre lawn in 35 minutes and your friend can mow a 1 acre lawn in 50 minutes, how long will it take for you to mow 6 acres together? How much will you make if your combined rate is $20/hour?
Answer:
80$ (maybe 85)
Step-by-step explanation:
combined rate =20$/hour
It can take 85 minutes for you and your friend to mow 2 acres. 35+50=85. So 85*3 (because 6/2=3) is the number of minutes you work. 255 minutes. So 4.25 hours. If you are only being paid for hours, then you will make $80. If you are being paid the extra minutes the $85. I believe that the answer you should pick is $80.
Answer:
$41.18
Step-by-step explanation:
35/50 = 0.7
Therefore, in the time it takes you mow 1 acre, your friend mows 0.7 acres
Therefore, for every 35 minutes = 1 + 0.7 = 1.7 acres are mowed by you and your friend combined.
⇒ 1.7 ÷ 35 = 0.04857142... acres mowed every minute
⇒ 6 ÷ 0.04857142... = 123.5294118... minutes to 6 acres
Therefore, it takes 35/17 hours for you and your friend to mow 6 acres
If your rate is $20 per hour, then 35/17 x 20 = $41.18

a rectangle is also a square
the diagonals are not lines of symmetry
a rectangle has two sets of parallel sides
Answer:

I know that B and D are both true for rectangles which limits the answers to A and C.
But I don't think it's C because if the line is going diagonally through the rectangle then they won't be lines of symmetry.

8. The logo for a company is a regular hexagon inscribed inside a circle. The logo will
be painted on the side of the company's office building. The radius of the circle will be
8 ft. Find the area of the hexagon to the nearest whole foot.
Divide the hexagon into 6 equal streak triangles which would have side length equal to the radius of the circle.
the area of an equal lateral triangle = sqrt(3)/4 x radius^2
the area of the hexagon would be 6 x sqrt(3)/4 x radius^2
Area = 6 x sqrt(3)/4 x 8^2 = 166.2768 square feet
rounded to the nearest whole foot = 166 square feet.

For each value of y, determine whether it is a solution to 2y> 18.
Answer:
2y>18......
2(8)= 16>18 no
2(11)= 22>18 yes
2(12)= 24>18 yes
2(6)= 12>18 no
Answer:
Step-by-step explanation:
We have 4 value of y : 8 ; 11 ; 12; 6
To determine whether it is a solution to the inequality 2y > 18, we have to substitute these values in
Substitute 8 in, we get : 2 x 8 > 18
16 > 18 (not true)
So, this is not a solution
Substitute 11 in, we get : 2 x 11 > 18
21 > 18 (true)
So, this is a solution
Substitute 12 in, we get : 2 x 12 > 18
24 > 18 (true)
So, this is also a solution
Substitute 6 in, we get : 2 x 6 > 18
12 > 18 (not true)
So, this is not a solution
There are 2 values that satisfy this inequality for y : 11 and 12

A scale drawing of a rectangular park had a scale of 1 cm = 80 m.
9.1 cm
12 cm
What is the actual area of the park in meters squared?
Answer:
8,736m squared
Step-by-step explanation:
ok so if the park drawing has sides measuring 9.1cm by 12cm, and our scale is 1cm=80m we can solve as follows:
area of the model is length x width = 9.1x12=109.2cm squared
now we know 1cm=80m and we have 109.2cm so we can multiply 109.2cm by 80m to get the area of the actual park which is 8,736m squared

D O 1/4
Answer:
D
Step-by-step explanation:
Firstly,you must divide (6,2) to (x¹y¹).After that,you must divide (10,3) to (x²y²).Then you must substract (y²-y¹,x²-x¹).It will be like this (3-2,10-6).So the correct answer is 1,4 (D).Hope you will understand!

Aaden owns a small business selling used books. He knows that in the last week 87 customers paid cash, 5 customers used a debit card, and 24 customers used a credit card.
Based on these results, express the probability that the next customer will pay with cash as a percent to the nearest whole number.
Using it's concept, it is found that there is a 75% probability that the next customer will pay with cash.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
In this problem, out of 87 + 5 + 24 = 116 customers, 87 paid with case, hence the probability as a decimal is given by:
p = 87/116 = 0.75.
As a percentage, we have that:
0.75 x 100% = 75%.
75% probability that the next customer will pay with cash.

Beatriz went on a road trip. By the end of the first day, she was 200\text{ km}200 km200, end text from the starting point of her trip, in a direction that is a °300, degree rotation from east. By the end of the second day, she was 150\text{ km}150 km150, start text, space, k, m, end text from where she was at the beginning of that day, in a direction that is a 250\degree250°250, degree rotation from east. What is Beatriz's direction, relative to the starting point of her trip, by the end of the second day?
The direction of Beatriz relative to the starting point of her trip is approximately [tex]278.806^{\circ}[/tex].
How to find the position of Beatriz relative to the starting point of her tripAfter a careful reading of the statement, we find that final position ([tex]\vec r[/tex]) by the end of the second day is found by means of this vector sum:
[tex]\vec r = \vec r_{1} + \vec r_{2}[/tex] (1)
Where:
[tex]\vec r_{1}[/tex] - Vector distance of the first day relative to starting point, in kilometers. [tex]\vec r_{2}[/tex] - Vector distance of the second day relative to the final point of [tex]\vec r_{1}[/tex], in kilometers.If we know that [tex]\vec r_{1} = (200\,km \cdot \cos 300^{\circ}, 200\,km\cdot \sin 300^{\circ})[/tex] and [tex]\vec r_{2} = (150\,km\cdot \cos 250^{\circ}, 150\,km\cdot \sin 250^{\circ})[/tex], then final position of Beatriz relative to origin is:
[tex]\vec r = (200\,km\cdot \cos 300^{\circ}, 200\,km\cdot \sin 300^{\circ})+(150\,km \cdot \cos 250^{\circ}, 150\,km\cdot \sin 250^{\circ})[/tex]
[tex]\vec r = (48.670, -314.159)\,[km][/tex]
And the direction relative to the starting point ([tex]\theta[/tex]), in degrees, is found by following inverse trigonometric relation:
[tex]\theta = \tan^{-1} \frac{r_{y}}{r_{x}}[/tex] (2)
If we know that [tex]r_{x} = 48.670\,km[/tex] and [tex]r_{y} = -314.159\,km[/tex], then the direction of Beatriz relative to the starting point of her trip is:
[tex]\theta = \tan^{-1} \left(\frac{-314.159\,km}{48.670\,km} \right)[/tex]
[tex]\theta \approx 278.806^{\circ}[/tex]
The direction of Beatriz relative to the starting point of her trip is approximately [tex]278.806^{\circ}[/tex]. [tex]\blacksquare[/tex]

If m∠CED = 56° and m∠AEB = (7x – 8)° then what is m∠BEC?
Using the definition of angles on a straight line, the measure of angle BEC is: 62°.
What are Angles on a Straight Line?Angles that lie on a straight line add up to 180 degrees.
Thus, given that EB bisects ∠AEC, therefore:
m∠BEC = 1/2(180 - m∠CED)
Plug in the values
m∠BEC = 1/2(180 - 56)
m∠BEC = 1/2(124)
m∠BEC = 62°
