Answer:
C, F, D
Step-by-step explanation:
For each side of each triangle, think of the side as the hypotenuse of a right triangle. Then use the Pythagorean theorem to find the length of the hypotenuse, which is the side of the triangle.
Left problem:
From point C to point A, go 2 left and 7 up.
[tex] AC = \sqrt{2^2 + 7^2} = 7.3 [/tex]
From point A to point B, go 5 right and 1 down.
[tex] AB = \sqrt{5^2 + 1^2} = 5.1 [/tex]
From point B to point C, go 6 down and 3 left.
[tex] BC = \sqrt{6^2 + 3^2} = 6.7 [/tex]
Perimeter = 7.3 + 5.1 + 6.7 = 19.1
Do the same for the other triangles.
Middle problem:
From point F to point D, go 2 left and 7 up.
[tex] FD = \sqrt{2^2 + 7^2} = 7.3 [/tex]
From point D to point E, go 7 right and 2 down.
[tex] DE = \sqrt{7^2 + 2^2} = 7.3 [/tex]
From point E to point F, go 5 down and 5 left.
[tex] EF = \sqrt{5^2 + 5^2} = 7.1 [/tex]
Perimeter = 7.3 + 7.3 + 7.1 = 21.7
Right problem:
From point L to point J, go 7 left and 1 up.
[tex] LJ = \sqrt{7^2 + 1^2} = 7.1 [/tex]
From point J to point K, go 4 up and 5 right.
[tex] JK = \sqrt{4^2 + 5^2} = 6.4 [/tex]
From point K to point L, go 2 right and 5 down.
[tex] KL = \sqrt{2^2 + 5^2} = 5.4 [/tex]
Perimeter = 7.1 + 6.4 + 5.4 = 18.9

Suppose that your boss must choose four employees in your office to attend a conference in Jamaica. Because all 19 of you want to go, he decides that the only fair way is to draw names out of a hat. What is the probability that you, Samuel, Lisa, and Andrew are chosen
Answer: the probability that I, Samuel Lisa and Andrew are chosen is 0.0003
Step-by-step explanation:
Given that;
Number of 4 employees are to be chosen from 19 of them;
so Number of ways to choose 4 employees from 19 employees = ?
we know that;
c(n,r) = [tex]\left[\begin{array}{ccc}n\\r\end{array}\right][/tex] = n! / ( r!(n-r)!)
so we substitute
c(19,4) = [tex]\left[\begin{array}{ccc}19\\4\end{array}\right][/tex] = 19! / ( 4!( 19-4 )!) = 3876
so the probability that I, Samuel Lisa and Andrew are chosen will be;
⇒ 1 / 3876 = 0.0002579 ≈ 0.0003
the probability that I, Samuel Lisa and Andrew are chosen is 0.0003

What is the perimeter of polygon LMNPQ
Answer: c for maps
Step-by-step explanation:
17.66 units is the perimeter of the polygon.
What is Perimeter?The perimeter of a two-dimensional form is the space surrounding it. It represents the total length of the shape's sides. The units used to measure the sides of the form, such as meters, centimeters, inches, or feet, determine the units used to measure the perimeter.
To find the perimeter of the polygon LMNPQ, we need to add up the lengths of all the sides.
The distance formula for finding the distance between two points [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] is:
[tex]d = \sqrt{(x_2 - x_1)^2 + (y-2 - y-1)^2)[/tex]
Using this formula, we can find the lengths of each side of the polygon:
[tex]LM = \sqrt{(2 - 4)^2 + (4 - 2)^2} = \sqrt{8}\\MN = \sqrt{(5 - 2)^2 + (8 - 4)^2} = \sqrt{25}\\NP = \sqrt{(8 - 5)^2 + (4 - 8)^2}= \sqrt{25}\\PQ = \sqrt{(6 - 8)^2 + (2 - 4)^2} = \sqrt{8}\\QL = \sqrt{(4 - 6)^2 + (2 - 2)^2} = 2[/tex]
Therefore, the perimeter of the polygon LMNPQ is:
Perimeter = LM + MN + NP + PQ + QL
= √8 + √25 + √25 + √8 + 2
≈ 2.83 + 5 + 5 + 2.83 + 2
≈ 17.66
So, the perimeter of the polygon LMNPQ is approximately 17.66 units.

If csctheta=11/4 & tan Thea< 0 Use the fundamental identities to evaluate cottheta.
Answer:
[tex]\cot{\theta} = -\frac{\sqrt{105}}{11}[/tex]
Step-by-step explanation:
Fundamental identities:
These following trigonometric identities are used to solve this question:
[tex]\sin^{2}{\theta}+\cos^{2}{\theta} = 1[/tex]
[tex]\csc{\theta} = \frac{1}{\sin{\theta}}[/tex]
[tex]\cot{\theta} = \frac{\cos{\theta}}{\sin{\theta}}[/tex]
With the cossecant, we can find the sine. So:
[tex]\csc{\theta} = \frac{1}{\sin{\theta}}[/tex]
[tex]\frac{11}{4} = \frac{1}{\sin{\theta}}[/tex]
[tex]11\sin{\theta} = 4[/tex]
[tex]\sin{\theta} = \frac{4}{11}[/tex]
With the sine, we find the cosine.
Since the tangent is negative, the cosine is negative. So
[tex]\sin^{2}{\theta}+\cos^{2}{\theta} = 1[/tex]
[tex](\frac{4}{11})^{2} + \cos^{2}{\theta} = 1[/tex]
[tex]\frac{16}{121} + \cos^{2}{\theta} = \frac{121}{121}[/tex]
[tex]\cos^{2}{\theta} = \frac{105}{121}[/tex]
[tex]\cos{\theta} = -\frac{\sqrt{105}}{11}[/tex]
Cotangent:
[tex]\cot{\theta} = \frac{\cos{\theta}}{\sin{\theta}}[/tex]
[tex]\cot{\theta} = \frac{-\frac{\sqrt{105}}{11}}{\frac{4}{11}}[/tex]
[tex]\cot{\theta} = -\frac{\sqrt{105}}{11}[/tex]
The function Y=4.75+2.20(X-1) can be used to determine the cost in dollars for a taxi ride in Houston, TX. What is the rate of change of the cost in dollars with respect to the number of miles?
Answer:
2.20 dollars/mile
Step-by-step explanation:
Given the function:
y = 4.75 + 2.20(x-1)
Before we get the rate of change of the cost, we need to write the expression in the form y = mx+c where;
m is the rate of change of the cost
From the function given:
y = 4.75 + 2.20(x-1)
Open the parenthesis
y = 4.75 + 2.20x -2.20
y = 2.20x + 2.55
On comparing with the standard
m = 2.20
Hence the rate of change of the cost in dollars with respect to the number of miles is 2.20 dollars/mile

Answer:

Step-by-step explanation:
if 50% is 7 what is 25%, 75%, and 100%
Answer:
100% = 14
75% = 10.5
25% = 3.5
Answer:
100% = 1475% = 10 1/250% = 725% = 3 1/2Step-by-step explanation:
50% if a number is also 1/2 of that number. So, we multiply 7 by 2 to get 14.
Now we know that we need to solve for 25%, 75%, and 100% of 14.
100% of a number is just that number, so 100% of 14 is 14.
To solve for 75% of 14, we multiply 3/4 by 14.
3/4 x 14/1 = 42/4 = 10 1/2
The final number to solve for is 25% of 14.
1/4 x 14/1 = 14/4 = 3 1/2
Which of these expressions equal 15 when x=1/2 and y=3? Circle all that apply. Please help with this my teacher need me to work out xy+3 1/2+20x Btw guys 3 1/2 are mixed numbers if your wondering
Answer:
15
Step-by-step explanation:
First you would replace the x and y's with 1/2 and 3.
So it would look like: (1/2) (3) + 3 1/2 + 20 (1/2)
Next, you go by PEMDAS (parenthesis, exponents, multiplications, division, addition, subtraction)
So you would first multiply and the parenthesis that I added mean multiplication.
1.5 + 3.5 + 10
So then all that is left to do is add because I multiplied everything out.
So it is 5 + 10 which is 15
