Answer:
7. c(n) = 10 +2(n -1)
8. c(20) = 48
Step-by-step explanation:
7. Your arithmetic sequence has first term a1=10 and constant difference d=2. The explicit formula for terms of an arithmetic sequence is ...
an = a1 +d(n -1)
If we use c(n) as the function name for the function giving the number of chairs in row n, then we can fill in the numbers we know to get ...
c(n) = 10 + 2(n -1)
__
8. Evaluating the function when n=20, we find ...
c(20) = 10 +2(10-1) = 10 +2·19 = 10 +38
c(20) = 48
There are 48 chairs in row 20.

Solve the equation | w + 1.5 = 8.75
Answer:
8.75-1.5=7.25
w=7.25
Step-by-step explanation:
Answer:
w = 7.25
Step-by-step explanation:
w + 1.5 = 8.75
To find what w is, you need to isolate. To isolate w from 1.5, you have to subtract 1.5 by 1.5.
w + 1.5-1.5 = 8.75
What you do to one side of the equal sign, you have to do to the other
w + 1.5-1.5 = 8.75 - 1.5
1.5-1.5 cancels out and 8.75 - 1.5 equals to 7.25
w = 7.25

The numbers 1 through 10 are written on individual cards and placed in a bag. If you reach into the bag and pull out a cards, what is the probability that it will not be a 9
Answer:
9/10
Step-by-step explanation:
There are 10 cards in total (1-10 is 10 numbers). Only 1 of the numbers is a 9. So the probability of picking the 9 is 1/10. Then do 1 - 1/10 to find the probability of not picking the 9. This is 9/10.

The proportion of American adults who spend between 6 and 9.99 hours a day, inclusive, on digital devises is approximately 1/3. The proportion of Americans adults who spend more than 9.99 hours on a digital dev is approximately 2/7. Find the proportion of American adults who spend at least 6 hours on digital devices. Write your result as a fraction.
Answer: 13/21 of the American adults spend at least 6 hours on digital services.
Step-by-step explanation:
The proportion that spends between 6 hours and 9.99 hours is 1/3
The proportion that spends more than 9.99 hours is 2/7
We want to find the proportion who spends at least 6 hours.
This is easy, we just need to combine the two groups from above, and that will give use the proportion that spends 6 hours or more.
We only need to add:
1/3 + 2/7
Now, the first problem we see here is that the denominators are different, then we need to rewrite both fractions to have the same denominator.
We know that 3*7 = 21, then we can use 21 as the common denominator, by multipliying by 7/7 (this is equal to 1) the first fraction, and by 3/3 the second one:
1/3 = (1/3)*1 = (1/3)*(7/7) = 7/21
2/7 = (2/7)*1 = (2/7)*(3/3) = (3*2)/21 = 6/21
Then the previous sum becomes:
1/3 + 2/7 = 7/21 + 6/21 = 13/21
This means that 13/21 of the american adults spend at least 6 hours on digital services.

You decide to take a hot air balloon ride and remember to take binoculars to look around while you are airborne. As the balloon rises, you use a GPS to determine your height in meters, h, and the distance in kilometers, d, to the farthest object that you can see. The table below shows the two measurements.
Height in meters 15 30 45 60 75 90 105
Distance in kilometers 13.833 19.562 23.959 27.665 30.931 33.833 36.598
1. Determine a function that could be used to model the data in the table.
Make sure to use h for height and d for distance.
2. If the balloon is 800 meters high, what is the farthest distance that you would be able to see? Round answer to the nearest whole number

In kite WXYZ, mZWY = 41° and mXYW = 11°
What is mWZY?
Answer:
128°
Step-by-step explanation:
In kite WXYZ, WY and XZ are longer and smaller diagonals respectively.
Longer diagonal bisects the opposite angles.
[tex] \therefore m\angle ZYW =m\angle XYW[/tex]
[tex] \because m\angle XYW = 11\degree... (given) [/tex]
[tex] \therefore m\angle ZYW =11\degree [/tex]
[tex] In\: \triangle WYZ[/tex]
[tex] m\angle ZYW + m\angle ZWY + m\angle WZY=180\degree [/tex]
[tex] 11\degree + 41\degree+ m\angle WZY=180\degree [/tex]
[tex] 52\degree+ m\angle WZY=180\degree [/tex]
[tex] m\angle WZY=180\degree - 52\degree [/tex]
[tex] \purple{\bold {m\angle WZY=128\degree}} [/tex]

What is the slope of the line that passes through the points (8,-4) and (6,3) in simplest form
Step-by-step explanation:
Rise of y-value = (-4) - (3) = -7.
Run of x-value = (8) - (6) = 2.
Slope of the line = Rise / Run = (-7) / (2) = -3.5.

If the slope of a line 1 is , what is the slope of line 2 which is perpendicular to line 1.
Step-by-step explanation:
let's say that x is the slope of line 1.
the slope of a perpindicular line is the negative reciprical of x
the slope of line 2 is then -1/x
Find the slope of the line represented by the data below
Answer:
Slope = -4
Step-by-step explanation:
Let us solve the question
∵ The slope of the line is m = Δy/Δx
∵ Δy is the change of y ⇒ Δy = y2 - y1
∵ Δx is the change of x ⇒ Δx = x2 - x1
→ Choose from the table x1, y1 and x2, y2
∵ x1 = -3 and y1 = 12
∵ x2 = -2 and y2 = 8
→ Use them to find Δx and Δy
∵ Δx = -2 - (-3) = -2 + 3 = 1
∴ Δx = 1
∵ Δy = 8 - 12 = -4
∴ Δy = -4
→ Use them to find the slope
∵ m = Δy/Δx
∴ m = [tex]\frac{-4}{1}[/tex]
∴ m = -4
∵ m is the slope of the line
∴ The slope of the line is -4

how do i solve this pls help me i got 30 mins left :(
10 points and marked brainliest!!!!!
Answer:
y = 4
Step-by-step explanation:
In this situation, because all the angles have the same arc mark, they must have the same measure which means that the triangle is equiangular. Therefore, you can use the definition of an equilateral triangle which states that if the triangle is equiangular, it must be equilateral which means that all sides are the same. This is because x + x + x = 180 → 3x = 180 → x = 60. When you learn trigonometry, you will realize that the proportion of sides corresponds to the angles. Or you could experiment and you may realise that if the angles of the triangles are all 60° then you can only form a triangle where the sides are all equal. If all sides are the same, then 9y - 3 = 7y + 5
So if 9y - 3 = 7y + 5, then
9y - 3 = 7y + 5 →
[subtract 7y from both sides]
9y - 7y - 3 = 7y - 7y + 5 →
2y - 3 = 5 →
[add 3 to both sides]
2y - 3 + 3 → 5 + 3 → 2y = 8 →
[divide both sides by 2]
y = 4

Answer: x = 4
Step-by-step explanation:
JL = 2 (MN)
3x - 2 = 2 (x + 1)
3x - 2 = 2x + 2
Subtract 2x from both sides
x - 2 = 2
Add 2 to both sides
x = 4
