In the triangle below, what ratio is sin θ?
Answers
Thus, our answer is [tex]$\frac{36}{39}=\boxed{\frac{12}{13}}$[/tex].
Answer: The required ratio is [tex]\dfrac{12}{13}.[/tex]
Step-by-step explanation: In the given triangle, we are to find the ratio of sinθ.
We know that
in a right-angled triangle, the ratio sine of an angle is given by the length of the perpendicular divided by the length of the hypotenuse.
For the given right-angled triangle, we get
[tex]\sin\theta=\dfrac{perpendicular}{hypotenuse}\\\\\\\Rightarrow \sin\theta=\dfrac{36}{39}\\\\\\\Rightarrow \sin\theta=\dfrac{12}{13}.[/tex]
Thus, the required ratio is [tex]\dfrac{12}{13}.[/tex]
angie andKenny play online video games angie buys 1 software package and 3 months of game play. Kenny buys 1 software package and 4 months of game play. each software package costs $20. if there total cost is $117 what is the cost of one month game play
Answers
Kenny buys 1 software package and 4 months of game play
price of each software package = $20
total cost = $117
cost of one month game play = ?
let y is the cost of one month play
Angie buys 3 months game play and paid $20 = 20 + 3y
Kenny buys 4 months game play and paid $20 = 20 + 4y
total cost of both is $117
So the equation becomes,
(20 + 3y) + (20 + 4y) = 117
7y + 40 = 117
7y = 117 - 40
7y = 77
dividing with 7 on both sides, we get
y = 11
so, $11 is the cost of one month game play

For the ordered pair, give three other ordered pairs with θ between −360° and 360° that name the same point. (3, 135°)
Answers
Three other ordered pairs with θ between −360° and 360° that name the same point as (3, 135°) are (−243, −45°), (−177, −15°), and (315, 495°).
Explanation:The ordered pairs (−243, −45°), (−177, −15°) and (315, 495°) all name the same point as (3, 135°) with θ between −360° and 360°.
To find these ordered pairs, you can add or subtract 360° to the given angle of 135° while keeping the x-coordinate constant at 3.
For example, you could subtract 360° from 135° to get −225° and combine it with the x-coordinate of 3 to get the ordered pair (3, −225°).

BC is tangent to circle A at B and to circle D at C. What is AD to the nearest tenth? Look at image attached.
Answers
AB ⊥ BC and CD ⊥ BC ⇒ ABCD is a right trapezoid.
You can find the AD using formula:
[tex]AD= \sqrt{BC^2+(AB-CD)^2} \\ \\ AD= \sqrt{19^2+(10-7)^2} = \sqrt{361+9}= \sqrt{370} \approx 19.2[/tex]
Answer:
1. 19.2
Step-by-step explanation:
Please find the attachment.
Since we know that radius is perpendicular to tangent of a circle. So AB will be perpendicular to BC at c and DC is perpendicular to CB at C.
Now we will construct a perpendicular line to radius AB at point E from the center of our small circle. Since we have two right angles at point B and C so we will also have right angles at point E and D as well.
Length of CD is is 7 so length of BE will be 7 as well and length of EA will be 10-7=3. Length of DE will be equal to length BC that is 19.
Now we have formed a right triangle and now we will use Pythagoras theorem to find the length of AD.
[tex](AD)^{2}=(DE)^{2}+(EA)^{2}[/tex]
Upon substituting our values in above formula we will get,
[tex](AD)^{2}=(19)^{2}+(3)^{2}[/tex]
[tex](AD)^{2}=361+9[/tex]
[tex](AD)^{2}=370[/tex]
Upon taking square root of both sides of our equation we will get,
[tex]AD=\sqrt{370}[/tex]
[tex]AD=19.2353840616713448\approx 19.2[/tex]
Therefore, the length of AD will be 19.2 and 1st option is the correct choice.

bla bla bla 20 characters
Answer:
-7
Step-by-step explanation:
We are given that a function
[tex]y=-2+5 sin(\frac{\pi}{12}(x-2))[/tex]
We have to find the minimum value of y.
We know that range of sin x is [-1,1].
[tex]-1\leq sin(\frac{\pi}{12}(x-2))\leq 1[/tex]
[tex]-5\leq 5sin(\frac{\pi}{12}(x-2))\leq 5[/tex]
[tex]-5-2\leq -2+5sin(\frac{\pi}{12}(x-2))\leq 5-2[/tex]
[tex]-7\leq -2+5sin(\frac{\pi}{12}(x-2))\leq 3[/tex]
[tex]-7\leq y\leq 3[/tex]
Maximum value of y=3
Minimum value of y=-7
Hence, the minimum value of given function =-7

x=4
sub back
y=1/2x
y=1/2(4)
y=2
(4,2) is the solution
To find the solution of y₁ = 1/2 x and y= -x + 6, let's y=y₁
-x + 6 = 1/2 x ↔ -2x +12 = x ↔ -3x= -12 and x = 4. For x = 4 , y =2.
And the solution is the intersection point between y and y₁ which is nothing but the solution or te coordinate of this point that is (4,2)

if you roll a normal dice 120 times. How many odd numbers would you expect to get
Answers
This means there's a 50% chance of an odd number, so 120/2 = 60
Answer:
60 odd numbers
Step-by-step explanation:
A normal dice has 6 different sides numbered from 1 to 6, each side has the same probability of appearing when you roll the dice, i.e., in the long run each number will appear 1/6 of the times. We have three different odd numbers in a normal dice each will appear 1/6 of the times in the long run. Therefore, in the long run we hope to get 3/6 = 1/2 of the times an odd number and rolling the dice 120 times will produce about 120(1/2) = 60 odd numbers.

y = 1
solution is (0,1)
The given system of equations, x - 2y = 2 and x - 2y = -2, are parallel lines and do not intersect, thus there is no common solution to the system.
Explanation:In mathematics, to find the solution to a system of equations, we generally try to find the values of variables that satisfy all the equations in the system. When looking at the given equations: x - 2y = 2 and x - 2y = -2, we can see that there is something strange. These two equations are equivalent to each other, meaning they represent the same line. This is due to the fact that both equations have the same coefficients for the x and y variables (1 and -2 respectively). So, if two lines are equivalent, they are essentially the same line. This means there are infinitely many solutions which satisfy this system of equations, since all points on the line satisfy both equations. However, if two lines have the same coefficients but different constants (the numbers without the variables), as in our case, then they are parallel and do not intersect, indicating that there's no solution for the system of equations. Therefore, this system of equations has no solution.

20c + 10b = 800

Multiply the second equation by -2.
20c + 10b = 800

Now it is only to add the two equations.
0 - 50b = -1000
b = -1000/-50
b = 20
Now that we have discovered the 'b' we will substitue in the equation.
10c + 30 . 20 = 900
10c + 600 = 900
10c = 300
c = 300/10

Answers
Answer:
The correct statement is:
On average, the height of a garden gnome varies 3.2 inches from the mean of 6 inches.
Step-by-step explanation:
We are given a data of 11 gardens as:
2 9 1 23 3 7 10 2 10 9 7
Now on removing the outlier i.e. 23 (since it is the very large value as compared to other data points) the entries are as follows:
x |x-x'|
2 4
9 3
1 5
3 3
7 1
10 4
2 4
10 4
9 3
7 1
Now mean of the data is denoted by x' and is calculated as:
[tex]x'=\dfrac{2+9+1+3+7+10+2+10+9+7}{10}\\\\x'=\dfrac{60}{10}\\\\x'=6[/tex]
Hence, Mean(x')=6
Now,
∑ |x-x'|=32
Now mean of the absolute deviation is:
[tex]\dfrac{32}{10}=3.2[/tex]
This means that , On average, the height of a garden gnome varies 3.2 inches from the mean of 6 inches.
