Answer:
Sonya pays a flat fee of $30 for her phone bill and pays $2 per gigabyte she uses per month. Put Sonya's bill as an equation with d being how many gigabytes she uses per month.
Step-by-step explanation:
We get the flat fee of $30 from "30 + 2d" and the $2 per gigabyte from "30 + 2d" and since we want to find out Sonya's total bill, that's where the + in "30 + 2d" comes from. We want the variable to be d therefore d is how many gigabytes she uses per month.

A total of 447 tickets were sold for the school play. They were either adult tickets or student tickets. The number of student tickets sold was two times the number of adult tickets sold. How many adult tickets were sold?
Answer:
149
Step-by-step explanation:
Adult ticket = x
Let the student ticket be 2x
2x + x = 447
3x = 447
x = 447/3
x = 149
If the number of student tickets sold was two times the number of adult tickets sold approximately 149 adult tickets were sold for the school play.
Let's assume the number of adult tickets sold as 'x'.
According to the given information, the number of student tickets sold is two times the number of adult tickets sold. So, the number of student tickets sold can be expressed as 2x.
We are also given that the total number of tickets sold is 447. Therefore, we can write the equation:
x + 2x = 447
Combining like terms, we have:
3x = 447
To find the value of x, we divide both sides of the equation by 3:
x = 447 / 3
Using a calculator, we find:
x ≈ 149

From 1985 through 1995, the yearly gross farrm revenue (in millions) in the United States can be modeled by the function R(t)=-t^2+7t+159 and the yearly farm cost (in millions) in the United States can be modeled by the function c(t)=t^2+131 where t is the number of years since 1985. Write a new function, P(t), that models the yearly profit after 1985
The profit function is simply the difference between the revenue function and the cost function. The profit function that models the yearly profit after 1985 is [tex]P(t) = 7t + 28[/tex]
Given that:
[tex]R(t) = t^2 + 7t + 159[/tex]
[tex]c(t) = t^2 + 131[/tex]
The profit function P(t) is calculated as follows:
[tex]P(t) = R(t) - c(t)[/tex]
So, we have:
[tex]P(t) = t^2 + 7t + 159 - (t^2 + 131)[/tex]
Open brackets
[tex]P(t) = t^2 + 7t + 159 - t^2 - 131[/tex]
Collect like terms
[tex]P(t) = t^2- t^2 + 7t + 159 - 131[/tex]
[tex]P(t) = 7t + 28[/tex]
Hence, the profit function that models the yearly profit after 1985 is [tex]P(t) = 7t + 28[/tex]

One angle of a right triangle is 2 less than 3 times the size of the other acute angle. What is the measure of each
angle?
Explanation:
Right-angled triangles have one of their angles to be 90°.
Angles in a triangle is 180°
=>The other two angles will sum up to 90°
Let x represent the other acute angle
2 less than 3 times the size of the other acute angle.
3(x)-2=one angle.
Equating both angles to 90°
=> other acute angle + one angle =90°
=> x+3x-2=90°
=>4x-2=90°
=>4x=90-2
=>4x=88
Divide both sides by 4
x=22°
Other acute angle=22°
One angle= 3(22)-2
=>66-2
=>64°
Proof= 22+64+2+90=180°

The sum of twice a number and 4 is equal to the sum of the number and 3.
Answer:
number = - 1
Step-by-step explanation:
let the number be n then twice the number is 2n , so
2n + 4 = n + 3 ( subtract n from both sides )
n + 4 = 3 ( subtract 4 from both sides )
n = - 1
The number is - 1

Tony is going to watch a movie in his collection. He has 5 action movies, 4 comedies, and 3 dramas.
He will randomly select one movie. What is the probability that the movie he selects is not a drama?
Answer:
9/12 (75%)
Step-by-step explanation:
There's a total of 12 movies (5+4+3).
Since there are 5 action, there's a 5/12 probability that he selects action.
4 comedies, so 4/12 probability that he selects comedies.
3 dramas, so 3/12 probability that he selects drama.
4+5 = 9 so there's a 9/12 or 75% probability that he won't select drama.

S(-4, -6) and T(-7, -3); Find R.
Answer:
(13,-6)
Step-by-step explanation:
The midpoint is the exact halfway point, so all you need to do is find the distance between those two points and apply it again.
First find the x coordinate. The distance from -9 to 2 is 11. So you add 11 to 2, and you get 13, which is your x coordinate.
Then do the same thing with the y coordinate. And you get -6.
Your endpoint is (13,-6)

Kimmie wants to earn money by baking and selling cookies. She works up a business plan and finds her cost and revenue functions whose graphs are shown above in green and red, respectively.
A). How many cookies must be produced and sold to break even?
B). What is the dollar amount coming in and going out if Kimmie just breaks even?
C).Use the formulas to write Kimmie's profit function, P(x), from producing and selling x cookies. (NOTE: Profit = Revenue - Cost)
D). How much profit will Kimmie earn if she produces and sells 520 cookies?
Using profit/cost/revenue concepts, it is found that:
a) 400 cookies must be produced and sold to break even.b) The dollar amount coming in and going out is $400.c) The profit function is [tex]P(x) = 2x - 800[/tex]d) Kimmie will earn a profit of $240.----------------------
The revenue function, that is, how much Kimmie earns selling x cookies, is given by: [tex]R(x) = 5x[/tex]The cost function, that is, the cost of producing x cookies, is given by: [tex]C(x) = 800 + 3x[/tex]----------------------
Question a:
The break even point is the value of x for which the revenue is the same as the cost, that is:
[tex]R(x) = C(x)[/tex]
Thus
[tex]5x = 800 + 3x[/tex]
[tex]2x = 800[/tex]
[tex]x = \frac{800}{2}[/tex]
[tex]x = 400[/tex]
400 cookies must be produced and sold to break even.
----------------------
Question b:
The dollar amount is [tex]R(400)[/tex].
[tex]R(400) = 5(400) = 200[/tex]
The dollar amount coming in and going out is $400.
----------------------
Question c:
Profit is revenue subtracted by cost, thus:
[tex]P(x) = R(x) - C(x)[/tex]
[tex]P(x) = 5x - (800 + 3x)[/tex]
[tex]P(x) = 5x - 800 - 3x[/tex]
[tex]P(x) = 2x - 800[/tex]
The profit function is [tex]P(x) = 2x - 800[/tex]
----------------------
Question d:
The profit earned is P(520), thus:
[tex]P(520) = 2(520) - 800 = 240[/tex]
Kimmie will earn a profit of $240.

Yes, Eugene needs to round down to show the time required to earn the full million dollars,
Yes, Eugene can use traditional rounding rules to show the time required to earn the full million dollars.
O No, Eugene would need to round the years up to the nearest whole number to show the time required to earn the full million dollars.
Not enough information to determine viability
Step-by-step explanation:
Is the salary $1,045,000/week? Then yes - easy.
Is the salary $1,045.00/week? Then yes, 19 years will get him there.
(1045/week)*(52 weeks/year) = $54,340/year
$1,000,000/($54,340/year) = 18.4 years
