Answer:
900 black and white copies were printed.
Step-by-step explanation:
From the information provided, you know that they printed 9 black and white copies for every 2 colored copies and you can use a rule of three to find the amount of black and white copies that were printed if they printed 200 color copies:
9 black and white → 2 colored
x ← 200 colored
x=(9*200)/2=900
According to this, the answer is that 900 black and white copies were printed.
The number of basketball games that must be scheduled in a league with n teams is given by G(n) = (n2 - n)/2 where each team plays every other team exactly once. A league schedules 21 games. How many teams are in the league?
Answer:
There are 7 teams in the league
Step-by-step explanation:
Given that the number of games is given by:
[tex]G(n) = \frac{(n^2-n)}{2}[/tex]
The equation will be used to determine the number of games. As we already know, that 21 games are scheduled which means G(n) is 21 so we have to find n when G(n) is 21
Putting this mathematically
[tex]21 = \frac{n^2-n}{2}[/tex]
Multiplying equation by 2
[tex]2*21 = 2*\frac{n^2-n}{2}\\42 = n^2-n\\n^2-n-42 = 0\\n^2-7n+6n-42 = 0\\n(n-7)+6(n-7) = 0\\(n-7)(n+6)=0\\n-7 = 0 => n=7\\n+6=0 => n=-6[/tex]
As the number of teams cannot be negative, the number of teams in league are 7.
Hence,
There are 7 teams in the league

At a school carnival, tickets can be purchased to participate in different activities. The table
shows the total cost for different numbers of tickets.
8 | 2.00
12 | 3.00
20 | 5.00
30 | 7.50
50 | 12.50
What is the constant of proportionality that relates y, the total cost in dollars, to x, thenumber of tickets purchased?
Answer:
0.25
Step-by-step explanation:
Here, we want to find the constant of proportionality that relates total cost in dollars to number of tickets purchased
Mathematically, that will be ;
7.50/30 = 1/4 = 0.25
Kindly note we can select any pair
The ratio of both at any point in time is constant
Joe takes out a loan for $19,000. He will pay the loan back monthly. The interest rate is 7.6% per year and the length of the loan is 4.5 years. TEKS 8.12(A), 8.12(B) 1. Determine how many payments need to be made. Explain.
Answer:
54 monthly payments
Step-by-step explanation:
the total number of payments = 4.5 years x 12 payments per year = 54 monthly payments
each monthly payment = loan / PV annuity factor
loan = $19,000PV annuity factor, 54 periods, 0.6123%) = 45.6139monthly payment = $19,000 / 45.6139 = $416.54

What equation in Slope-Intercept Form represents the line that passes through the points ( -3,3) and ( 1,2)?
Answer:
[tex]y=-\frac{1}{4}x+\frac{9}4}[/tex]
Step-by-step explanation:
Answer:
Step-by-step explanation:
(x₁ , y₁) = (3, -3) & (x₂ , y₂) = (1 , 2)
[tex]slope = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\[/tex]
[tex]= \frac{2-3}{1-[-3]}\\\\= \frac{-1}{1+3}\\\\=\frac{-1}{4}[/tex]
m = (-1/4)
y - y₁ = m(x - x₁)
[tex]y - 3 = \frac{-1}{4}(x - [-3])\\\\y - 3 = \frac{-1}{4} (x + 3)\\\\y - 3 = \frac{-1}{4}x-\frac{3}{4}\\\\ y = \frac{-1}{4}x-\frac{3}{4} + 3\\\\ y =\frac{-1}{4}x+\frac{-3+12}{4}\\\\ y =\frac{-1}{4}x+\frac{9}{4}[/tex]

A two-day moving truck rental from Best Rentals costs $60 and $0.35 per mile driven. A two-day moving truck rental from Easy Movers costs $80 and $0.25 per mile driven. Let m represent the number of miles driven. Which equation can be used to find the number of miles for which the rentals would cost the same amount? 60 + 0.35 m = 80 + 0.25 m 60 m + 0.35 = 80 + 0.25 m 60 + 0.35 m = 80 m + 0.25 m 60 m + 0.35 = 80 m + 0.25

From 2010 to 2011, the population of Queens increased by 16,075. Brooklyn's population increased by 11,870 more than the population increase of Queens. a) Estimate the total combined population increase of Queens and Brooklyn from 2010 to 2011. (Round the addends to estimate.)
Answer: 44000
Step-by-step explanation:
From the question, we are informed that the population of Queens increased by 16,075.
Brooklyn's population increased by 11,870 more than the population increase of Queens. This means that Brooklyn's population will be:
= 16075 + 11870
= 27945
The total combined population increase of Queens and Brooklyn from 2010 to 2011 will then be:
= 16075 + 27945
Estimating 16075 gives 16000
Estimating 27945 gives 28000
Adding then together equals
16000 + 28000 = 44000

Jason has a rectangular garden with the length of 10 m and a width of 3 m he will double the area of the garden by adding the same number of meters to both the length and the width what will be the length in meters of the garden after Jason in large is it
Answer:
2 m
Step-by-step explanation:
The length and width of a rectangular garden is 10 m and 3 m respectively.
He will double the area of the garden by adding the same number of meters to both the length and the width. Area = 2(10 × 3) = 60 m².
Let x is amount of increase in the length and width such that area will be :
(10+x)(3+x) =60
30+10x+3x+x² = 60
x²+13x-30=0
x²+15x-2x-30=0
x(x+15)-2(x+15)=0
x=2 and x = -15
Neglecting negative value, he aded 2 m toboth length and width of the garden.

The cooper family owns a luxery sedan and a compact car the fuel tank capacity for the luxury seden is 22.45 gallon and of the compact car is 8.7 gallons find the diffrence in the fuel tank of the teo car
Given :
The cooper family owns a luxery sedan and a compact car the fuel tank capacity for the luxury seden is 22.45 gallon and of the compact car is 8.7 gallons.
To Find :
The difference in the fuel tank of the two car.
Solution :
Capacity of sedan, S = 22.45 gallons.
Capacity of compact car, C = 8.70 gallons.
Difference in the capacity :
D = S - C
D = 22.45 - 8.70 gallons
D = 13.75 gallons
Therefore, difference in the fuel tank of the two car is 13.75 gallons.
Hence, this is the required solution.

Because of a problem in the program, the timer in a video player did not begin counting until the video had been playing for several seconds. The player began counting at 000 seconds, even though the video had already played 190190190 frames. The video plays 252525 frames per second. How many frames had the video already played when the time was equal to -3\dfrac{2}{5}−3 5 2 minus, 3, start fraction, 2, divided by, 5, end fraction seconds?
Answer:
105 frames
Step-by-step explanation:
Given that:
At 0 seconds, the video had already played 190 frames and there are 25 frames being played per second.
When the time is equal to [tex]3 \dfrac{2}{5}[/tex], the number of frames that are already being played is:
[tex]= 3 \dfrac{2}{5} \times 25[/tex]
[tex]= \dfrac{17}{5} \times 25[/tex]
= 17 × 5
= 85 frames.
But recall that, the frames had already played 190 frames at 0 seconds, then the number of frames that had already been played when the time is equal to [tex]3 \dfrac{2}{5}[/tex] is;
=(190 - 85) frames
= 105 frames

105

Step-by-step explanation:
Are all terminating and repeating decimals rational numbers? Explain.
Answer:
All terminating and repeating decimals are not rational numbers. For example, pi is a non-terminating & irrational number.
Step-by-step explanation:
The given statement "Are all terminating and repeating decimals rational numbers? Expla" is true.
Yes, all terminating and repeating decimals are rational numbers. A
rational number is defined as any number that can be expressed as a ratio of two integers, with the denominator not equal to zero.
Terminating decimals are those decimals that end after a finite number of digits.
For example, 0.75 is a terminating decimal because it ends after two digits. To show that such decimals are rational,
We can rewrite the decimal as a fraction.
0.75 can be expressed as 75/100 or simplified to 3/4.
Since both the numerator and denominator are integers, 0.75 is a rational number.
Now
Repeating decimals are those decimals that have a repeating pattern of digits after the decimal point.
For example, 0.3333... is a repeating decimal because the digit 3 repeats infinitely.
To show that repeating decimals are rational, we can use a similar approach to terminating decimals.
Take 0.3333... as an example.
We can represent this decimal as an infinite series:
0.3333... = 3/10¹ + 3/10² + 3/10³+ ...
This can be simplified using the formula for the sum of an infinite geometric series:
0.3333... = 3/10¹ + 3/10² + 3/10³+ ...
= (3/10)/( 1 - 1/10) (by sum of infinite geometric serires)
= 3/9
Since 3/9 can be simplified to 1/3, we can conclude that 0.3333... is a rational number.
Thus, all terminating and repeating decimals are rational numbers because they can be expressed as a ratio of two integers.
