The members of the drama club have 100 tickets to sell
to the school play. Students pay $5 per ticket, and
nonstudents pay $10 per ticket. The drama club needs
to collect at least $800 in total ticket sales. The system
of inequalities represents the number of student tickets,
s, and the number of nonstudent tickets, n, the members
must sell.
S + n < 100
5s + 10n > 800
Answer:40
Step-by-step explanation:
answer is 40
A
The number of tickets sold to the student is s = 40 (maximum) and to the nonstudent is n = 60(minimum) in order to collect at least $800 in total ticket sales.
The members of the drama club have 100 tickets to sell Students pay $5 per ticket, and nonstudents pay $10 per ticket. Inequalities given S + n < 100, 5s + 10n > 800. Maximum tickets for students and minimum tickets for nonstudents are to be determined.
Inequality can be defined as the relation of an equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.
Here,
Let S + n = 100 -----(1)
5s + 10n = 800 ----(2)
Solving equations 1 and 2
S = 40 and n = 60
in order to hold the inequality s should be a maximum of 40 or n should be a minimum of 60.
Thus, the number of tickets sold to the student is s = 40 (maximum) and to the nonstudent is n = 60(minimum) in order to collect at least $800 in total ticket sales.

1. Express the product of 2x2 + 7x – 10 and x + 5 in standard form.
Answer:
Step-by-step explanation:
It will be easier if you bring that binomial in-front, imo. But the main thing you want to do here is actually really easy. You have to distribute that x to every single term in the trinomial, then do the same thing for the 5. Add up everything.
Distribute the x and 5 like this:
[tex]x(2x^2+7x-10) + 5(2x^2+7x-10)[/tex]
[tex]2x^3+7x^2-10x+10x^2+35x-50[/tex]
Now combine like terms:
[tex]2x^3+17x^2+25x-50[/tex]
There's your answer. Btw, standard form means the exponents are in order high to low and all variables before constants
The product of the expression is 2x³ + 17x² + 25x - 50.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
2x² + 7x - 10 and x + 5
Multiply both expressions.
(2x² + 7x - 10) x (x + 5)
2x³ + 10x² + 7x² + 35x - 10x - 50
Combine like terms.
2x³ + 17x² + 25x - 50
Thus,
The expression is 2x³ + 17x² + 25x - 50.

There are 48 people in a gym class what fraction represents the number of people running? 5/8 of the people were in spin class 1/3 of the people were lifting weights the remaining people were running
Answer: B.1/24
Step-by-step explanation:
Find out the number of people in spin class and those lifting weights, subtract them from the total number in the gym and then make this a fraction.
Step 1
Number of people in spin class ;
= 5/8 * 48
= 30 people
Number of people lifting weights;
= 1/3 * 48
= 16 people
Step 2
Number of people running
= 48 - 30 - 16
= 2 people
Step 3
Convert this to a fraction in its lowest form;

Find the approximate side length of a square game board with an area of 199 Inches Squared
The side length of a square game board with an area of 199 inches² is 14.11 inches.
What is the area?An object's area is how much space it takes up in two dimensions. It is the measurement of the number of unit squares that completely cover the surface of a closed figure.
Given:
The area of the square is 199 inches²
Calculate the length of the square as shown below,
Area of the square = The length of the square × The length of the square
199 = l² (Here l is the length of the square)
l = √199
l = 14.11 inches
Thus, the length of the board is 14.11 inches.

If x+y=12 and xy=15,find the value of (x^2+y^2)
Answer: [tex]x^2+y^2=\dfrac{105\pm 18\sqrt6}{2}[/tex]
Step-by-step explanation:
EQ1: x + y = 12 --> x = 12 - y
EQ2: xy = 15
Substitute x = 12-y into EQ2 to solve for y:
(12 - y)y = 15
12y - y² = 15
0 = y² - 12y + 15
↓ ↓ ↓
a=1 b= -12 c=15
[tex].\ y=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}\\\\\\.\quad =\dfrac{-(-12)\pm \sqrt{(-12)^2-4(1)(15)}}{2(1)}\\\\\\.\quad =\dfrac{12\pm \sqrt{144-120}}{2}\\\\\\.\quad =\dfrac{12\pm \sqrt{24}}{2}\\\\\\.\quad =\dfrac{12\pm 2\sqrt{6}}{2}\\\\\\.\quad =6\pm \sqrt{6}[/tex]
Now, let's solve for x:
[tex]xy=15\\\\x(6\pm\sqrt6)=15\\\\x=\dfrac{15}{6\pm\sqrt6}\\\\\\x=\dfrac{15}{6\pm\sqrt6}\bigg(\dfrac{6\pm\sqrt6}{6\pm\sqrt6}\bigg)=\dfrac{6\pm \sqrt6}{2}[/tex]
Lastly, find x² + y² :
[tex]y^2=(6\pm \sqrt6)^2\quad \rightarrow \quad y^2=36\pm 12\sqrt6 +6\quad \rightarrow \quad y^2=42\pm 12\sqrt6[/tex]
[tex]x^2=\bigg(\dfrac{6\pm \sqrt6}{2}\bigg)^2\quad \rightarrow \quad x^2=\dfrac{42\pm 12\sqrt6}{4}\quad \rightarrow \quad x^2=\dfrac{21\pm 6\sqrt6}{2}[/tex]
[tex]x^2+y^2=\dfrac{21\pm 6\sqrt6}{2}+42\pm 12\sqrt6\\\\\\.\qquad \quad = \dfrac{21\pm 6\sqrt6}{2}+\dfrac{84\pm 24\sqrt6}{2}\\\\\\. \qquad \quad = \dfrac{105\pm 18\sqrt6}{2}[/tex]

A farmer needs to enclose three sides of a meadow with a fence (the fourth side is a river). The farmer has 30 feet of fence and wants the meadow to have an area of 112 sq-feet. What should the dimensions of the meadow be? (For the purpose of this problem, the width will be the smaller dimension (needing two sides); the length with be the longer dimension (needing one side). Additionally, the length should be as long as possible.)
Answer:
Width = 7 feets ; length = 16 feets
Step-by-step explanation:
Given the following :
Area of meadow = 112 sq feet
Width = W (smaller dimension and 2 sides)
Length = L (longer dimension and 1 side)
Yards of fence = 30 feets ;
Hence,
L + W = 30
L + 2W = 30
L = 30 - 2W - - - (1)
Recall:
Area = L * W = 112
Substitute value of L
112 = (30 - 2W) * W
112 = 30W - 2W²
2W² - 30W + 112 = 0
W² - 15W + 56 = 0
W² - 8W - 7W + 56 = 0
W(W - 8) - 7(W - 8) = 0
(W - 8) = 0 or (W - 7) =0
W = 8 or W = 7
Since length should be as long as possible, we take the shorter width :
W = 7
L + 2W = 30
L = 30 - 14
L = 16 feets

Answer:
Step-by-step explanation:
R.H.R. y = 22.50x + 45
S. R. : y = 35x + 30
35x + 30 = 22.50x + 45
12.50x + 30 = 45
12.5x = 15
x = 2.5 hours it have an same price total
The equation represents the cost after x hours.
At Rocking Horse Ranch:
y = 45 + 22.50x
At Saddlecreek Ranch:
y = 30 + 35x
The cost for both the Rocking Horse Ranch and Saddlecreek Ranch is the same after 1.2 hours.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 3 = 4 is an equation.
We have,
At Rocking Horse Ranch:
Admission = $45
Trail rides per hour = $22.50
At Saddlecreek Ranch:
Admission = $30.
Trail rides per hour = $35
We have to find out after how many hours the cost from both the Ranch is the same.
We can make two equations as,
y = 45 + 22.50x ____(1)
y = 30 + 35x _____(2)
Now,
From (1) and (2) we get,
45 + 22.50x = 30 + 35x
45 - 30 = 35x - 22.50x
15 = 12.50x
x = 15/12.50
x = 1.2
Thus,
The cost for both the Rocking Horse Ranch and Saddlecreek Ranch is the same after 1.2 hours.

Explain how to find the 52nd term using the explicit rule f(n)= 15n+10, then solve.
Answer:
790Step-by-step explanation:
Given the explicit rule function F(n) = 15n +10, in order to get the 52nd term of the sequence, we will have to substitute n = 52 into the rule given as shown;
f(52) = 15(52) + 10
f(52) = 780+10
f(52) = 790
Hence the 52nd term of the explicit rule is 790
