Answer:
Step-by-step explanation:
we know that
In a triangle
the ratio between the lengths of the two legs is equal to the tangent
so
therefore
the answer is
Option B
-------> could be the ratio
because is the value of the
Option C
------> could be the ratio
because is the value of the
Option E
-------> could be the ratio
because is the value of the
The options B, C and E giving the ratios are correct.
What are ratios?Ratio, in math, is a term that is used to compare two or more numbers. It is used to indicate how big or small a quantity is when compared to another. In a ratio, two quantities are compared using division.
Given that, a 30-60-90 right triangle, we need to find the ratio between the lengths of the two legs of the triangle,
Since, we know that,
In a right triangle, the ratio between the lengths of the two legs is equal to the tangent.
so,
Tan 30° = 1/√3
Also,
√3 / 3 = 1/√3
3/3√3 = 1/√3
Hence, the options B, C and E giving the ratios are correct.

What is the approximate surface area of the Hayden Sphere in terms of T?
4731 ft?
37857 ft?
75697 ft2
18927 ft?
Answers
Answer:
[tex]A=7569\pi \ ft^2[/tex]
Step-by-step explanation:
The diameter of a sphere is 87 feet.
We need to find its surface area. The formula for surface area is given by :
[tex]A=4\pi r^2[/tex]
Where
r is the radius of the sphere
[tex]A=4\pi \times (\dfrac{87}{2})^2\\\\=7569\pi \ ft^2[/tex]
So, the surface area of the sphere is equal to [tex]7569\pi \ ft^2[/tex].

If y=4, what does x equal??
Answers
Answer:
since y=4
from one of the equations
6x+4y=46
substitute y=4 In the equation
6x+4(4)=46
6x+16=46
6x=46-16
6x=30
divide both sides by the co efficient of'x'
6x/6=30/6

12/23 plus -11/23 e eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee
Answers
Answer:
1/23
Step-by-step explanation:
This honestly super easy, but here it is!
12/23+(-11/23)
With no negatives, it would be 12/23+11/23 and the answer would be 23/23 AKA 1, because 12+11=23.
With negatives though, you always have to subtract the number itself from the positive number if the number is negative. Here we will subtract 11 from 12, which brings us to 1/23.
Hope this helped!

Now, we have a right triangle with a known angle and a known side. With this type of triangle, we can use basic trigonometry applications.
The side opposite to the 90 degree angle is the hypotenuse. The hypotenuse is YZ. The two legs are WZ and YW.
We can use cosine function to find tangent because the YZ is not known.
tangent is side opposite of angle divided by side adjacent to angle.
tan(72) = WZ / 4.25
4.25tan(72) = WZ
0.3 = WZ
The courtyard outside East Middle School is in the shape of a rectangle and half-circle.
What is the approximate area of the courtyard?
Answers
Answer:
The correct option is the third one counting from the top. (5892 m^2)
Step-by-step explanation:
First, we need to remember that:
For a rectangle of length L and width W, the area is:
A = L*W
For a circle of diameter D, the area is:
A = pi*(D/2)^2
Where pi = 3.14
In the image, we can see a rectangle and half a circle, the total area of the image will be equal to the area of the rectangle plus the area of the half circle.
In the image, we can see a rectangle of length L = 100m and width W = 50m
Then the area of the rectangle is:
A = 100m*50m = 5000m^2
And we can see that for the half-circle the diameter is D = 50m
Note that the area of a half-circle is half of the area of a complete circle, then the area of that half-circle is:
A = (1/2)*(3.14*(50m/2)^2) = 981.25 m^2
If we add these two areas we get:
Total area = 5000m^2 + 981.25 m^2 = 5981.25 m^2
If we round it up, we get:
Total area = 5982 m^2
The correct option is the third one counting from the top.

The giant outlier is Palm Beach county. We can see that it lies well beyond the range of votes this regression model would predict for Buchanan, based on the observed linear trend between total votes and votes for Buchanan across all the other counties. Calculate the residual for Palm Beach county to determine just how much larger Buchanan's vote total was compared to what we'd predict based on the election results from the other counties.

Answer:
Hello your has some missing information attached below is the missing information
answer : 2355.62
Step-by-step explanation:
Calculating the residual for Palm Beach county
Given that total votes = 430772
and The regression equation = 56.115131 + 0.0023197 * Total Votes
The predicted Buchanan = 56.115131 + 0.0023197 * 430772 = 1055.377
while the Actual Votes Buchannan = 3411
Residual for Palm Beach county = Actual votes Buchannan - Predicted
= 3411 - 1055.377 = 2355.62
