At Petey's Pizza, two large one-topping pizzas and three dozen wings cost $54. Four large one-topping pizzas and one dozen wings cost $48. Let (L) represent the number of large one-topping pizzas, and let (W) represent the number of dozens of wings. Write a system of equations you could use to find the cost of a single one-topping pizza and a dozen wings.
Answer:
2L + 3W =54
4L + W = 48.
Step-by-step explanation:
Given
L = Large one-topping Pizzas
W = Dozen Wings
From the first statement; we have that:
2L and 3W cost $54.
The expression for this is:
2L + 3W =54
From the second statement; we have that:
4L and 1W cost $48.
The expression for this is:
4L + W = 48.
Hence; The system of equations is
2L + 3W =54
4L + W = 48.

Fun Zone charges an entrance fee
of $4.50 and $0.65 per ticket. Happy
Town charges $0.40 per ticket and a
$5.00 entrance fee. How many
tickets must be purchased in order
for the total to be the same at both
Fun Zone and Happy Town?
Answer:
2 tickets
Step-by-step explanation:
To be the same they must equal each other.
4.50 + 0.65x = 0.40x + 5
isolate the variable
subtract 4.50 from both sides
0.65x = 0.40x + 0.50
subtract 0.40x from both sides
0.25x = 0.50
divide both sides by 0.25
x = 0.50 ÷ 0.25
x = 2
Sione just landed a great job as an engineer where he will make $55,000 a year. The company he will work for guarantees a 3% pay increase each year so it's employees' salaries keep up with inflation. At the end of the 1st year Sione will have made $55,000 dollars. What is the recursive function that will represent this situation?
Answer:
s(x) = 55000*1.03^xStep-by-step explanation:
First year salary
$55000Annual pay rise

Find missing angle !.
Answer:
[tex]\huge\boxed{130 \textdegree}[/tex]
Step-by-step explanation:
We can use a couple of angle relationships to find the missing angle.
1. All angles in a triangle add up to 180°
We know that all angle in a triangle will add up to 180°. Since we know the measure of 2, we can find the other angle easily.
[tex]180-35-95\\\\180-130\\\\50[/tex]
So the other angle in the triangle is 50°.
2. The 50° angle and the missing angle are supplementary.
We know that the missing angle and the third triangle angle are supplementary. This means that their angle measures will add up to 180°.
Since we know one, we can find the measure of the other.
[tex]180-50\\\\130[/tex]
So the missing angle is 130°.

A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by the given equation. Using this equation, find the time that the rocket will hit the ground, to the nearest 100th of second.
Answer:
9.72 seconds
Step-by-step explanation:
9.72 seconds ( approx )
Step-by-step explanation:
Since, the equation that shows the height of the rocket from the ground,
Where,
x = time after launch, in seconds,
When the rocket hits the ground,
y = 0,
i.e.
By the quadratic formula,
∵ Time can not be negative,
So, the time taken to hit the ground = 9.716 seconds ≈ 9.72 seconds.
The time at which the rocket will hit the ground to the nearest hundredth of seconds is 15 seconds.
What is a quadratic equation?An algebraic equation of the second degree in x is a quadratic equation. The quadratic equation is written as ax2 + bx + c = 0, where x is the variable, and a must not be zero.
As per the given height of tower y in terms of time is seconds x
y = -16x² + 240x + 115
The height of the tower when the rocket hit the ground will be zero.
Thus, y = 0
0 = -16x² + 240x + 115
16x² - 240x - 115=0
By quadratic equation formula,
x = [-(-240) ± √((-240)²+4×16×(-115))]/ 2×16
x = [240 ± 254.8725]/32
x = 15.46 and x = -0.46 since time can be never negative thus 15.46 seconds will be correct.
15.46 to the nearest hundred is 15.
Hence "The time at which the rocket will hit the ground to the nearest hundredth of seconds is 15 seconds".

Answer:
The difference in cost per mile is $0.94.
Step-by-step explanation:
Uber
7x = 20.37
x = $2.91 per mile
Lyft
4y = 15.4
y = $3.85 per mile
3.85 - 2.91 = 0.94
Hello.
To find the difference in cost per mile, divide the cost by the amount of miles, then subtract the two answers.
20.37 / 7 = 2.91 (cost per mile {cpm} for Uber)
15.40 / 4 = 3.85 (cost per mile {cpm} for Lyft)
3.85 - 2.91 = 0.94
The difference in cost per mile is $0.94

A number is randomly selected from the set {1, 2, 3, 4, 5, 6, 7, 8}. If the number chosen is greater than 3, what is the probability it is odd?
Answer:
Hello!
The probability that the number chosen is greater then 3 and odd is 2/8
There are 5 numbers greater then 3, and of those 5, five and seven are the only odd numbers. So that is 2/8
Step-by-step explanation:
There are 5 numbers greater then 3, and of those 5, five and seven are the only odd numbers. So that is 2/8
If you are only talking about the numbers that are actually greater then 3 as your population, it is 2/5 :)
(I would appreciate Brainliest, please and thanks)
If a number randomly chosen is greater than 3, the probability that the number is odd is 2/5
How to determine the probability?The set of numbers is given as:
Set = {1, 2, 3, 4, 5, 6, 7, 8}.
The numbers greater than 3 are:
G3 = {4, 5, 6, 7, 8}
The odd numbers greater than 3 are
OG3 = {5, 7}
The required probability is then calculated using:
P = n(OG3)/n(G3)
This gives
P = 2/5
Hence, the probability is 2/5

A school nurse can give 25 eyes test in a two-hour period. How long will it atke the nurse to give eye test to all 600 student sin her school?
Answer:
96 hours
Step-by-step explanation:
25 eyes - 2 hours
1200 eyes* - x hours
[tex]x = \frac{2 \times 1200}{25} [/tex]
[tex]x = 96[/tex]
*each student has 2 eyes. So 600 students have 600×2=1200 eyes.
It will take the nurse 48 hours to give eye tests to all 600 students in her school.
What is Expression?An expression is combination of variables, numbers and operators.
If the nurse can give 25 eye tests in two hours, then she can give 12.5 tests in one hour (since 25 divided by 2 equals 12.5).
To give eye tests to all 600 students, the nurse will need to give 600 tests in total.
Using the rate of 12.5 tests per hour, we can set up a proportion:
12.5 tests / 1 hour = 600 tests / x hours
Apply Cross-multiplication
12.5 tests × x hours = 600 tests
Divide both sides by 12.5 tests
we get, x hours = 600 tests / 12.5 tests per hour
x hours = 48 hours
Therefore, it will take the nurse 48 hours to give eye tests to all 600 students in her school.
