Answer:
78.03
Step-by-step explanation:
14.50 + 10 + 48 = cost
cost = 72.25
tax = 5.78
total cost = cost + tax
total cost = 78.03

Complete question:
Benjamin decides to treat himself to breakfast at his favorite restaurant. He orders chocolate milk that costs \$3.25$3.25dollar sign, 3, point, 25. Then, he wants to buy as many pancakes as he can, but he wants his bill to be at most \$30$30dollar sign, 30 before tax. The restaurant only sells pancakes in stacks of 444 pancakes for \$5.50$5.50dollar sign, 5, point, 50. Let SSS represent the number of stacks of pancakes that Benjamin buys. 1) Which inequality describes this scenario?
Answer:
Kindly check explanation
Step-by-step explanation:
Given that :
Cost of chocolate milk = $3.25
Cost of pancakes = $5.50 (stack of 4)
Number of stacks of pancakes purchased = S
Maximum amount spent ≤ $30
Cost of chocolate + (Cost of pancake stack * number of stacks) ≤ $30
3.25 + 5.50S ≤ 30
5.50S ≤ 30 - 3.25
5.50S ≤ 26.75
S ≤ 26.75 / 5.50
S ≤ 4.86
Hence maximum number of pancake stacks he can purchase without exceeding budget = 4
Hence total number of pancakes = number of stacks * number in a stack
= 4 * 4
= 16
Answer:
Chose option have answer 3.25+5.50S [tex]\leq[/tex] 30
16 pancakes

The John Jay Theater Dept has tickets at $6 for adults, $4 for teachers, and $2 for students. A total of 280 tickets were sold for one showing with a total revenue of $1010. If the number of adult tickets sold was twice the number of teacher tickets, how many of each type of ticket were sold for the showing?
Answer:
number of adults tickets sold = x = 90
number of teachers tickets = y = 45
number of students tickets = z = 145
Step-by-step explanation:
Cost of tickets
Adults = $6
Teachers = $4
Students = $2
Total tickets sold = 280
Total revenue = $1010
Let
x = number of adults tickets
y = number of teachers tickets
z = number of students tickets
x + y + z = 280
6x + 4y + 2z = 1010
If the number of adult tickets sold was twice the number of teacher tickets
x = 2y
Substitute x=2y into the equations
x + y + z = 280
6x + 4y + 2z = 1010
2y + y + z = 280
6(2y) + 4y + 2z = 1010
3y + z = 280
12y + 4y + 2z = 1010
3y + z = 280 (1)
16y + 2z = 1010 (2)
Multiply (1) by 2
6y + 2z = 560 (3)
16y + 2z = 1010
Subtract (3) from (2)
16y - 6y = 1010 - 560
10y = 450
Divide both sides by 10
y = 450/10
= 45
y = 45
Substitute y=45 into (1)
3y + z = 280
3(45) + z = 280
135 + z = 280
z = 280 - 135
= 145
z = 145
Substitute the values of y and z into
x + y + z = 280
x + 45 + 145 = 280
x + 190 = 280
x = 280 - 190
= 90
x = 90
Therefore,
number of adults tickets sold = x = 90
number of teachers tickets = y = 45
number of students tickets = z = 145

Answer:
[tex]2z^4[/tex]
Step-by-step explanation:
Given the expression [tex]\frac{z^{-1}}{3} \div\frac{z^{-5}}{6}[/tex], we are to write it in the form of [tex]nz^n[/tex]. To do that we will simplify the given indicinal expression as shown;
[tex]\dfrac{z^{-1}}{3} \div\dfrac{z^{-5}}{6}\\= \dfrac{z^{-1}}{3} \times\dfrac{6}{z^{-5}}\\= \dfrac{6z^{-1}}{3z^{-5}}\\ = \dfrac{2z^{-1}}{z^{-5}}\\[/tex]
According to indices [tex]\dfrac{a^m}{a^n} = a^{m-n}[/tex], the resulting equation will become;
[tex]= \dfrac{2z^{-1}}{z^{-5}}\\= 2z^{-1-(-5)}\\= 2z^{-1+5}\\= 2z^{4}[/tex]
Hence expression in the form [tex]nz^n \ is \ 2z^4[/tex].

Tyler is packing lunches for a local youth program. He has 36 sandwiches, 72 apples, and 108 granola bars. What is the greatest number of lunches he can pack so that each lunch has an equal number of sandwiches, apples, and granola bars? How many of each item will the lunch contain?
Answer:
The greatest number of lunches he can pack so that each lunch has an equal number of sandwiches, apples, and granola bars is 12.
Each lunch will contain 3 sandwiches, 6 apples and 9 granola bars
Step-by-step explanation:
The greatest common divisor (GCD) of two or more numbers is the largest number by which these numbers can be divided, that is, it is the largest number that divides them all exactly.
In other words, the greatest common divisor of two numbers a and b is the largest number that divides a and divides b.
To find the greatest common divisor of two or more numbers, you start by breaking those numbers down into prime factors. In this case:
36=2²*3²
72 = 2³*3²
108 = 2²*3
The greatest common divisor is obtained by choosing only the prime factors common to the numbers, raised to the smallest exponent. That is, you choose only the common factors and those that are repeated must be raised to the minimum exponent.
The 2 appears as a prime factor in the three decompositions, whose minimum exponent is 2.
3 also appears as a common factor, whose minimum exponent is 1.
By doing the multiplication to get the greatest common divisor, you get:
2²*3=12
So the greatest number of lunches he can pack so that each lunch has an equal number of sandwiches, apples, and granola bars is 12.
To calculate how many lunches each item will contain, you simply divide the amount you have of each item by the most lunches Tyler can pack, 12.
Sandwiches: 36÷12= 3
Apples: 72÷12= 6
Granola bars: 108÷12= 9
Each lunch will contain 3 sandwiches, 6 apples and 9 granola bars

Answer:
C. 24.27 cm
Step-by-step explanation:
sin 65° = opposite ÷ hypotenuse
sin 65° = 22/x
multiply both sides of the equation by x
(sin 65°)x = 22
divide both sides of the equation by sin 65°
x = 22 ÷ sin 65°
punch in 65 sin into your calculator
x = 22 ÷ 0.90631
x = 24.27 cm
