a theater has 50 seats in the front row. there are 4 additional seats in each row after that. how many seats are in the 20th row?
Answers
Answer:
126
Step-by-step explanation:
The number of seats in each row can be expressed in the sequence
50, 54, 58, 62, ..... ,
This is an arithmetic sequence with n th term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 50 and d = 4 , then
a₂₀ = 50 + (19 × 4) = 50 + 76 = 126
That is there are 126 seats in the 20th row

a machine fills 150 bottles of water every 8 minutes how many minutes will it take to fill 675 bottles?
Answers
Answer:
36 minutes
Step-by-step explanation:
150b / 8m = 18.75b/m we want to know how many bottle of water per minute
675b/18.75b/m = 36m
The machine fills 675 bottles of water every 36 minutes which is determine the proportion.
What is the proportion?A mathematical assessment of two numbers is called a proportion. If two sets of provided numbers rise or fall in the same relation, then the ratios are said to be directly proportional to each other.
We have been given that a machine fills 150 bottles of water every 8 minutes
To determine the number of minutes will it take to fill 675 bottles.
Let the required number of minutes would be x
According to the given question, we can write a proportion as
150 bottles : 8 minutes = 675 bottles : x minutes
⇒ 150 / 8 = 675 / x
Apply the cross-multiplication operation,
⇒ 150x = 675×8
⇒ 150x = 5400
⇒ x = 5400 / 150
⇒ x = 36
Therefore, the required number of minutes would be 36.

Vertex of the given parabola = (1, -4)
Since, vertex form of a parabola is given by,
y = (x - h)² + k
Here (h, k) is the vertex
Now substitute the coordinates (1, -4) in the equation.
y = (x - 1)²- 4 [Vertex Form]
Further solve this equation,
y = x² - 2x + 1 - 4
y = x² - 2x - 3 [Standard form]
Further write this equation in the factored form,
y = x² - 3x + x - 3
y = x(x - 3) + 1(x - 3)
y = (x + 1)(x - 3) [Factored form]

Paula's time swimming in the Ironman Triathlon was 1 hour 25 minutes. Her time biking was 5 hours longer than her swimming time. She ran for 4 hours 50 minutes. How long did it take her to complete all three parts of the race? Use the model to help you organize your thinking.
Answers
Answer: 12 hrs 40 mins
Step-by-step explanation:
The swimming time was 1 hour 25 minutes.
Her biking time was 5 hours longer than the swimming time so it was:
= 1 hr 25 mins + 5 hours
= 6 hours 25 mins
Her running time was 4 hrs 50 mins.
Add them all up to find the amount of time ran. First add up the minutes:
= 25 + 25 +50
= 1 hr 40 minutes
Hours = 1 + 6 + 4
= 11 hours
Total:
= 11 + 1 hr 40
= 12 hrs 40 mins
Using our formula y2-y1/x2-x1, find the slope of a line through two ordered pairs show your work (-3,-4)(4,5)
Answers
Given:
The two points are (-3,-4) and (4,5).
To find:
The slope of the line that passes through the given points.
Solution:
The slope formula is
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
The line passes through the points (-3,-4) and (4,5). So, the slope of the line is
[tex]m=\dfrac{5-(-4)}{4-(-3)}[/tex]
[tex]m=\dfrac{5+4}{4+3}[/tex]
[tex]m=\dfrac{9}{7}[/tex]
Therefore, the slope of the given line is [tex]m=\dfrac{9}{7}[/tex].
