what degree of rotation about the origin will cause the triangle below to map onto itslef
Answers
Answer:
[tex]360^o[/tex]
Step-by-step explanation:
Given
The attached plot
Required
Which degree maps the triangle onto itself
The degrees that can map a point, line, or shape onto itself are:
[tex]\theta=360,720,1080,1440, 1800, 2160, 2520, 2880, 3240, 3600[/tex]
i.e. multiples of 360
Looking at the given options
[tex](a)\ 360^o[/tex] is correct because it can be found in the listed multiples
In other words, it will map point [tex](x,y)[/tex] to point [tex](x,y)[/tex]

You roll a six sided number cube and flip a coin.What is the probability of rolling a number less than 6 and flipping heads?Write fraction in simplest form
Answers
Answer:
5/12
Step-by-step explanation:
Probability to roll a number<6 = 5/6 (each number has probability of 1/6, and there are 5 numbers < 6)
Probability to toss heads = 1/2
Condition "and" = multiplication of probabilities=5/6*1/2=5/12

Solve for x. The triangles in each pair are similar. Please explain!! I’m so confused
Answers
Answer:
[tex]x = 5[/tex]
Step-by-step explanation:
Given
[tex]\triangle JDC[/tex] similar to [tex]\triangle JKL[/tex]
Required
Find x
To do this, we make use of the following equivalent ratios
[tex]JK:JL = JD:JC[/tex]
This gives
[tex]98 : 63 = 7x + 7:27[/tex]
Express as fraction
[tex]\frac{98 }{ 63} =\frac{ 7x + 7}{27}[/tex]
Multiply both sides by 27
[tex]27 * \frac{98 }{ 63} =\frac{ 7x + 7}{27} * 27[/tex]
[tex]27 * \frac{98 }{ 63} =7x + 7[/tex]
[tex]3* \frac{98 }{ 7} =7x + 7[/tex]
[tex]3* 14 =7x + 7[/tex]
[tex]42 =7x + 7[/tex]
Collect like terms
[tex]7x = 42 - 7[/tex]
[tex]7x = 35[/tex]
Divide both sides by 7
[tex]x = 5[/tex]

Respuesta:
Población = Todos los pasajeros en el autobús
Muestra = los 10 pasajeros entrevistados
Variable = inocencia del conductor; por tanto es una variable cualitativa
Explicación paso a paso:
La población se refiere a todo el conjunto de observaciones que están relacionadas con un evento o experimento en particular. Aquí, todos los pasajeros del vehículo constituyen la población, ya que nuestra investigación se basa en el vehículo.
La muestra es un subconjunto de la población que generalmente se elige al azar de manera que sea representativa de la población.
La variable que pretendemos medir es si el conductor es inocente o no. Por lo tanto, llamamos a esto la variable medida. Debido a que la culpa o la inocencia no es numérica, se considera una variable cualitativa.

Answers
Answer:
10.9
Step-by-step explanation:
Given that,
Hypotenuse = 12
One leg = 5
We need to find the another leg. Let it is b. We can solve it using Pythagoras theorem as follows :
[tex]H^2=h^2+b^2\\\\b^2=H^2-h^2\\\\b^2=12^2-5^2\\\\b=10.9[/tex]
So, another leg is 10.9.
Maya and Zack built the tent below in their backyard how much material did they use to build the tent
Answers
Answer:
[tex]Area = 279ft^2[/tex]
Step-by-step explanation:
Given
See attachment for tent
Required
The material needed
This implies that we calculate the surface area of the tent.
This is calculated as:
Area = 2 * Area of Congruent triangles + 2 * Area of Congruent Rectangles + Area of Base Rectangle
So, we have:
[tex]Area = 2 * \frac{1}{2} * 6 * 8 + 2 * 10.5 * 7 + 10.5 * 8[/tex]
[tex]Area = 48 + 147 + 84[/tex]
[tex]Area = 279ft^2[/tex]
the cost of 21 articles is equal to selling price of 18 articles. find the profit or loss percent.
Answers
Answer:
If all the items are sold, the profit percentage is 14.28%.
Step-by-step explanation:
Given that the cost of 21 articles is equal to selling price of 18 articles, to find the profit or loss percent the following calculation must be performed:
21 = 100
21 - 18 = X
21 = 100
3 = X
(3 x 100) / 21 = X
300/21 = X
14.28 = X
Therefore, if all the items are sold, the profit percentage is 14.28%.

The perimeter of a rectangle is 73 inches. If the length is 16 inches, write and solve an equation to
find the width.
Answers
Answer:
Step-by-step explanation:
The equation for finding the perimeter of a rectangle is 2Lx2H
So since the length is 16, you multiply that by 2 to get 32.
Then you subtract 32 from 73 which leaves you with 41, then your equation is left as 2H=41, so you divide 41 by 2 which is 20.5, and that is your height

y=[tex]\frac{1}{2}x-2[/tex]
Step-by-step explanation:
Perpendicular lines have negative reciprocal gradients(slopes) so the slope of your new line would be 1/2. Then you use the point to find the new y-intercept
y=mx+b
2=[tex]\frac{1}{2}[/tex](8)+b

Kelly Slater and Andy Irons are in a surf competition among 10 competitors.
If all surfers are at an equal surfing level, then what is the probability that Kelly will place 1st and Andy will place
2nd? Write your answer as a simplified fraction.
Answers
Answer:
The probability that Kelly will place 1st and Andy will place 2nd is 1/90, or 1.11%.
Step-by-step explanation:
Since Kelly Slater and Andy Irons are in a surf competition among 10 competitors, to determine, if all surfers are at an equal surfing level, then what is the probability that Kelly will place 1st and Andy will place 2nd, the following calculation must be performed:
1/10 x 1/9 = X
0.1 x 0.11 = X
0.01111 = X
1/90 = 0.011111 = X
Therefore, the probability that Kelly will place 1st and Andy will place 2nd is 1/90, or 1.11%.
