Answer:
30 degrees.
Step-by-step explanation:
Rotational symmetry is defined as a figure having the same appearance when rotated by a certain angle.
The wheel has 12 "handles." We can use these as reference points when rotating the image.
We also know that we can rotate by a total of 360 degrees. We can say that:
360/12 = 30 degrees.
Each time you rotate the wheel by 30 degrees, the image will end up on another handle (looks the same). This shows rotational symmetry.

Kiley found $8.75 in nickels and quarters in the cabinet above the washing machine. Let x represent the number of nickels
she found and y represent the number of quarters. Which equation written in standard form represents the amount of
money she found, and what does its y-intercept represent?
O The equation in standard form is 0.05x + 0.25y = 8.75; the y-intercept represents that if she found 0 nickels, she must
have found 175 quarters.
The equation in standard form is 0.05x + 0.25y = 8.75; the y-intercept represents that if she found 0 nickels, she must
have found 35 quarters.
The equation in standard form is x + 5y =175; the y-intercept represents that if she found 0 nickels, she must have found
175 quarters.
The equation in standard form is x + 5y =175; the y-intercept represents that if she found 0 nickels, she must have found
35 quarters.
Answer:
0.05x+0.25y=8.75; the y intercept represents that if she found 0 nickels she must have found 35 quarters.
Step-by-step explanation:
1. Solve for y:
0.25y= 8.75-0.05x (subtract 0.05x on both sides)
y= (8.75-0.05x)/0.25 (divide by 0.25 on both sides)
2. Since the y intercept can be found when x equals 0, plug in 0 for x into the equation.
y=(8.75-0.05(0))/0.25
y= 8.75/0.25
y=35

Lines A B, A D, and A C create two angle. The space between lines A B and A D is (2 x minus 10) degrees. The space between lines A D and A C is (x minus 20) degrees.
If mAngleDAC = 25°, what is mAngleDAB in degrees?
What is mAngleBAC in degrees?
Answer:
it is 80 degrees for first and then 105 degrees for second
Step-by-step explanation:
The measure of ∠BAC is 105°.
Given that, ∠DAC=(x-20)°=25° and ∠DAB=(2x-10)°.
What are adjacent angles?The two angles are said to be adjacent angles when they share the common vertex and side.
Now, ∠DAC=(x-20)°=25°
⇒x=45°
So, ∠DAB=(2x-10)°=80°
Then ∠BAC=∠DAC+∠DAB=25°+80°=105°
Therefore, the measure of ∠BAC is 105°.

Using system of equations answer this word problem. 1) Scott and Paul are selling Pies for a school fundraiser. Customers can buy apple pies and lemon meringue pies. Scott sold 3 apple pies and 12 lemon meringue pies for a total of 141$. Paul sold 2 apple pies and 5 lemon meringue pies for a total of 64$ What is the cost of each of one apple pie and one lemon meringue pie? (Show your work and tell me how to do it and I'll give you brainlist!)
Answer:
Step-by-step explanation:
We first need to come up with a system of equations that models this situation. Let's call apple pies "a" and lemon pies "L". Then we look to each individual involved in selling these pies and come up with an equation for each. Scott sold 3 apple and 12 lemon pies. The combination of this number of these 2 types of pies grossed him $141. In equation form, the combination of this number of these 2 types of pies is an addition thing. Namely,
3a + 12L = 141
For Paul, his combination was 2 apple and 5 lemon for a total of $64. His equation is
2a + 5L = 64
We need to solve this system either by substitution or elimination/addition to come up with the cost of both types of pies. I chose elimination/addition because I think in this case it is easier, and easier is good.
Setting up for elimination/addition:
3a + 12L = 141
2a + 5L = 64
Let's first eliminate the a terms. That means that the coefficient on each a has to be the same but with different signs. The LCM of both 3 and 2 is 6, so we will multiply the top equation by 2 and the bottom equation by -3 (we could also have chosen to eliminate the L's first; we also could have chosen to eliminate the a's first but made the 2 negative instead of the 3. As long as you do the math correctly, you'll get the same answer regardless of how you choose to do it). Multiplying the first equation by 2 and the second by -3 gives us a new system:
6a + 24L = 282
-6a - 15L = -192
The reason this is called the elimination or addition method is because the goal is to eliminate, but you do that by adding the columns together. As you can see, 6a - 6a eliminates the a terms, right? What you're left with then is
9L = 90 and
L = 10
Now that we know the cost of a lemon pie, we can back sub in to solve for the cost of an apple pie. It doesn't matter which equation you back sub into, as long as it has both an L and an a in it. I'll choose the first equation we wrote when we took on this nightmare:
3a + 12L = 141. Subbing in 10 for L gives us
3a + 12(10) = 141 and
3a + 120 = 141 and
3a = 21 so
a = 7
That means that lemon pies cost 10 each and apple pies cost 7 dollars each.
Maria gathered the data in the table. She finds the line of best fit to be y = 2.78x – 4.4. A 2-column table with 5 rows. The first column is labeled x with entries 1, 2, 3, 4, 5. The second column is labeled y with entries negative 2, 1.3, 4.2, 7.3, 8.9. What is the residual value when x = 4?
Answer:
The residual value when x = 4 is 0.58
Step-by-step explanation:
The residual value of a fitted function is the difference between the actual value of the data for a given input and the result of the fitted function. On this problem for the actual values, when [tex]x = 4[/tex] we have [tex]y_{data} = 7.3[/tex] , although, for the fitted function on the same value of "x", we have a different value, which is calculated below:
[tex]y(4) = 2.78*4 - 4.4 = 6.72[/tex]
The residual value is:
[tex]\text{residual value} = y_{data} - y_{function} = 7.3 - 6.72 = 0.58[/tex]
The residual value when x = 4 is 0.58
Functions are written in terms of variables. The residual value when the value of x is 4 is 0.58
Table and valuesFunctions are written in terms of variables. Given the following function that represent the data in the table
y = 2.78x – 4.4
If the value of x is 4, the corresponding value of y is expressed as:
y = 2.78(4) – 4.4
y = 11.12 - 4.4
y = 6.72
Determine the residual value
Residual value = 7.3 - 6.72
Residual value = 0.58
Hence the residual value when the value of x is 4 is 0.58

The measure of each interior angle of a regular polygon can be expressed as x-5 and the number of sides by 10x. Determine the following the number of degrees in each exterior angle
Answer:
0.1948° in each exterior angle
Step-by-step explanation:
The exterior angle measure is 360° divided by the number of sides. Here, that is 10x, so the exterior angle is ...
360°/(10x) = 36°/x
The measure of the interior angle is the supplement of the exterior angle, so we have ...
x -5 = 180 -(36/x)
x(x -5) = 180x -36 . . multiply by x
x^2 -185x = -36 . . . . . subtract 180x
x^2 -185x +8556.25 = -36 +8556.25 . . . . complete the square
(x -92.5)^2 = 8520.25
x -92.5 ≈ ±92.3052
x ≈ 184.8052 or 0.19480
It does not make any sense for the number of sides to be 10·0.1948 = 1.948, so we assume the number of sides is 184.8052·10 = 1848.
Then the number of degrees in each exterior angle is ...
36°/184.8052 = 0.1948
