Answer:
x=15°
Step-by-step explanation:
Angles ∠2 and ∠4 are supplementary, so ∠2+∠4=180°
That equals to 2x+10+4x+80=180.
You can solve that equation to find what x is equal to.
2x+10+4x+80=180
6x+90=180
6x=90
x=15°

The table shows the number of visitors y (in thousands of people) an amusement park has had each year over x years. Use a graphing calculator to find an equation of the line of best fit. Round the slope and y-intercept to the nearest hundredth. Then identify and interpret the correlation coefficient.
Answer:
The equation of the line of best fit is: y = -2.33x + 591.78
The correlation coefficient is: -0.99
There is a strong negative correlation
Step-by-step explanation:
The negative correlation is seen in the sign of the correlation coefficient, which is negative.
The correlation is strong because the absolute value of the correlation coefficient (0.99) is near to one

What was his mean time?
Answer:
20 minutes
Step-by-step explanation:
The mean, or average of a data set can be found by adding all the values together, and dividing by the number of values.
The data set is: 20 minutes, 22 minutes and 18 minutes
1. Add the values together
Add all the numbers in the set together.
Data set: 20, 22, 18
Add them: 20+22+18
60
2. Divide by the number of values
Count how many numbers are in the set.
In this set, there are 3 numbers.
Divide 60 by 3
60/3 =20
20 minutes
His mean time is 20 minutes.
Answer:
30 minutes
Step-by-step explanation:
Mean means the average so the average equals (20+22+18)/2

The price of the box of 10 markers is $7. The price of the box of 24 markers is $14. All prices without tax and the price of the boxes are the same.
Part A:
Write an equation that tells the price Y for the number of markers X.
Part B:
How much would a box of 64 markers cost?
Answer:
It costs $34 to buy a box of 64 markers.
Step-by-step explanation:
Check whether we are working with a direct proportion, in which case the comparison between the price and the number of markers would be the same.
$ 14 ÷ 24 = $0.58 and $ 7 ÷ 10 = $ 0.70
The prices differ, so they are not directly proportional.
The reason is that both prices include the price of the box, which is the same. This can be thought of as the constant.
If you were to draw a graph of price (on the y -axis) and number of markers (on the x -axis) you would get a straight line where the
y -intercept would be the price of the box and the slope would be the price of a marker. (rate of change of price)
Let's find the slope.
m = (y _2 − y _1 /x _2 − x _1)
m = ($14 −$ 7 /24− 10) = ($ 7 /14 markers) = $ 0.50 / marker
Therefore each marker costs
$ 0.50 or 50 c
the price of 64 markers is:
64 × 0.5 = $ 32.00 ← this is just the markers,
How much does the box cost? Consider
$ 7 for 10 markers at $ 0.50 each
$ 7 − 10 × $ 0.50 = $ 7 − $ 5 = $ 2
The box itself costs $2
The total cost of 64 markers in a box would be:
$ 2 + $ 32 = 34#

Answer:
Carbon is a chemical element with atomic number 6 which means there are 6 protons and 6 electrons in the atomic structure. The chemical symbol for Carbon is C. It is nonmetallic and tetravalent—making four electrons available to form covalent chemical bonds. Carbon is one of the few elements known since antiquity.

For a given rectangle the length equal 3x + 2 and the width equal 5 what is the area of the rectangle
Answer:
15x + 10.
Step-by-step explanation:
To find the area of a rectangle, recall the formula is A = l × w. Therefore:
A = (3x + 2) (5)
Distribute the '5':
A = 15x + 10
Therefore, the area of the rectangle of 15x + 10.
Answer:
15x+10 units ^2
Step-by-step explanation:
The area of a rectangle can be found using:
A = l * w
The length of the rectangle is 3x+2 and the width is 5.
l=3x+2
w=5
Substitute these values into the formula.
A= 3x+2 *5
This can be rewritten as: (Commutative property of Multiplication)
A= 5* 3x+2
A= 5(3x+2)
Distribute the 5. Multiply each term inside the parentheses by the number outside the parentheses.
A= (5*3x) + (5*2)
A= 15x +10
A= 15x+10 units^2
The area of the rectangle is 15x+10 square units.

theta, equals, start fraction, 8, pi, divided by, 9, end fraction radians to degrees.
Answer:
[tex]160^\circ[/tex] is the degrees value of [tex]\theta = \dfrac{8 \pi}{9}[/tex].
Step-by-step explanation:
We are given the following details about the angle [tex]\theta[/tex]:
[tex]\theta =\dfrac{8\pi}{9}\text{ radians}[/tex]
It is know that the relation between radians and degree units is as follows:
[tex]\pi \text{ radians} = 180 ^\circ[/tex]
We can use simply use unitary method to convert radian value of [tex]\theta[/tex] to degrees.
[tex]\pi \text{ radians} = 180 ^\circ[/tex]
[tex]\Rightarrow 1 \text { radian}= \dfrac{\pi}{180} ^\circ[/tex]
[tex]\Rightarrow \dfrac{8\pi}{9} \text{ radians} = \dfrac{180}{\pi} \times \dfrac{8\pi}{9} ^\circ\\\Rightarrow \dfrac{180 \times 8}{9}^\circ\\\Rightarrow 20 \times 8^\circ\\\Rightarrow 160 ^\circ[/tex]
Hence, [tex]\theta = 160^\circ[/tex]
Find the center, radius, and intercepts of the circle given below and then sketch the graph of the circle.
x²+(y-1)^2=1
Answer:
Center (0, 1)
Radius 1
x-intercept (0, 0)
y-intercept (0, 0), (0, 2)
Step-by-step explanation:
(1) A circle that has center (a, b) and radius r can have the equation as below:
(x - a)^2 + (y - b)^2 = r^2
Re-write the original equation: x^2 + (y - 1)^2 = 1, we have:
(x - 0)^2 + (y - 1)^2 = 1^2
=> The center of this circle: (a, b) = (0, 1) and the radius r = 1
(2) To find out the x-intercept, we substitute y = 0 into original equation.
=> x^2 + (0 - 1)^2 = 1
=> x^2 + 1 = 1
=> x^2 = 0
=> x = 0
=> x-intercept (0, 0)
(3) To find out the y-intercept, we substitute x = 0 into original equation.
=> 0^2 + (y - 1)^2 = 1
=> (y - 1)^2 = 1
=> y - 1 = -1 or y - 1 = 1
=> y = 0 or y = 2
=> y-intercept (0, 0) and (0, 2)

A. 7/2
B. 7√3/3

Answer B
One thing that gave it away was that we are dealing with a 30-60-90 triangle so in the final equation we should have (x=Any number) [tex]x\sqrt{3}[/tex] not square root two
The triangle ABC with ∠C as right angle , BC = 7 and ∠b = 30 degrees has AC as 7√3 / 3
What is a right angle triangle?A right angle triangle is a triangle that has one of its angle as 90 degrees. Therefore, the sides can be found using trigonometric ratios.
BC = 7 units
∠b = 30°
Hence, AC can be found as follows;
tan 30° = opposite / adjacent
tan 30 = AC / 7
cross multiply
AC = 7 tan 30
AC = 7 × 1 / √3
AC = 7 / √3
AC = 7√3 / 3

The tens digit is three less than the units digit. If the digits are reversed, the sum of the reversed number and the original number is 121. Find the original number.
help!!!!!
Answer: 47, 74
Step-by-step explanation:
Let x = units digit
x – 3 = tens digit
Then the number is 10(x – 3) + x and the reversed number is 10(x) + (x – 3)
Equation
The reversed number plus the original number equal 121.
10(x) + (x – 3) + 10(x – 3) + x = 154
10x + x – 3 + 10x -30 + x = 121
22x – 33 = 121
22x = 154
x = 7 (units digit)
x – 3 = 4 (tens digit)
