By taking the quotient between the total debt and what they earn in a sold-out show, we conclude that they need to sell a total of 7 sold-out shows.
10:
A discount of 30%. Correct option is B.
How many sold-out shows they need to cover the loan?Answering part 9:
We know that they asked for a loan of $8,000, such that an interest of the 6% is applied to this, so the total amount that they need to return is:
$8,000*(1 + 6%/100%) = $8,000*(1.06) = $8,480
Now we know that the theater has 150 seats, and each ticket costs $8.50, so for every sold-out show they earn a total of:
T = 150*$8.50 = $1,275
Then the number of sold-out shows that they need is given by the quotient:
$8,480/$1,275 = 6.65
Rounding to the next whole number we get to 7. To cover the debt, they need to sell a total of 7 sold-out shows.
10. The original price is $180 and she pays $126, then the discount k is:
$180*k = $126
k = $126/$180 = 0.7
and 1 - 0.7 = 0.3
So the discount is of the 30%.

Answer:
Quotient = 3x² - 2x + 3
Remainder = 1
Step-by-step explanation:
We have to solve: [tex]\dfrac{3 x^{3} + 4 x^{2} - x + 7}{x + 2}[/tex]
We will use synthetic division to calculate this divisor
First, take the constant term of the divisor with the opposite sign and write it to the left. Write the coefficients of the dividend expression to the right Where there is no coefficient for a specific x term, use 0
Step 1: Write down the first coefficient asis
| x³ x² x¹ x⁰
2 | 3 4 -1 7 ← Coefficient row
|
---------------------------------
3 ← Result Row
Step 2: Multiply the entry in the left part of the table by the last entry in the result row and add he obtained result to the next coefficient of the dividend, and write down the sum.
| x³ x² x¹ x⁰
-2 | 3 4 -1 7
| -6 -6 = -2 x 3
---------------------------------
3 -2 -2 = 4 + (-6)

A pizza shop offers a choice of 3 sizes (small, medium, and large) and 7 different toppings. Different pizzas can be created by changing the size and/or the choice of toppings. If Cody wants to order a pizza with exactly 2 different toppings, how many different pizzas can he create?
1. 6
2. 21
3. 63
4. 121
Using permutation and combination we can calculate that she can get 63 different types of pizza.
Permutations and combinations are the various ways in which elements from a set may be chosen, typically without replacement, to create subsets. This choice of subsets is known as a permutation when the order of the selection is taken into account, and as a combination when it is not.
The total of the decisions we make given an initial set of n items is known as a combination. Permutation, on the other hand, counts the number of possible arrangements of n separate items. This will help us recall that combinations place more emphasis on choice than on placement, order, or arrangement.
Now Cody can get any two toppings out of the 7.
Number of ways in which Cody can pick 2 toppings out of 7 is given by the use of combination,
7C2 = 21 different ways.
Again the number of ways in which 3 different pizza s can be selected is given by 21 × 3 = 63 ways.
Hence Cody can create 63 different pizzas.

2. y = (x - 7)^2
Help with these problems above would be greatly appreciated, thanks!
Answer:
1. 3 and -5
2. 7
Step-by-step explanation:
The zeros of functions are the x-values when y = 0, i.e the point(s) at which the line crosses the x-axis.
To find the zeros of the given functions, set the function to zero and solve for x.
Question 1Given function:
[tex]y=5(x-3)(x+5)[/tex]
Set the function to zero:
[tex]\implies 5(x-3)(x+5)=0[/tex]
[tex]\implies \dfrac{5(x-3)(x+5)}{5}=\dfrac{0}{5}\\[/tex]
[tex]\implies (x-3)(x+5)=0[/tex]
Using the Zero Product Property, set each factor equal to zero and solve for x:
[tex]\implies (x-3)=0 \implies x=3[/tex]
[tex]\implies (x+5)=0 \implies x=-5[/tex]
Therefore, the zeros of the function are 3 and -5.
Question 2Given function:
[tex]y=(x-7)^2[/tex]
Set the function to zero and solve for x
[tex]\implies (x-7)^2=0[/tex]
[tex]\implies \sqrt{(x-7)^2}=\sqrt{0}[/tex]
[tex]\implies x-7=0[/tex]
[tex]\implies x=7[/tex]
Therefore, the zero of the function is 7 (with multiplicity 2).

By solving a simple linear equation, we will get that:
36° = m∠AOB
How to find m∠AOB?
We can write a simple linear equation here, we know that:
m∠AOC = 108°
And we also know that:
m∠AOC = 3*m∠AOB
If we replace the first equation into the second one, then we will have the linear equation:
108° = 3*m∠AOB
And we want to solve this for m∠AOB, to do so, we just need to divid both sides by 3, we will get:
108°/3 = m∠AOB
36° = m∠AOB

Omar has been training for the Candlewood Footrace. The first week he trained, he ran 7 days and took the same two routes each day: 3 miles around the track before work and a longer route through his neighborhood after work. By the end of the week, Omar had run a total of 63 miles.
Which equation can you use to find how many miles, x, Omar ran each day after work?
The equation that can be use to find the how many miles, x, Omar ran each day after work is x = (Total distance he ran in one week - The total distance he run before the work in one week) ÷ 7, he ran 6 miles each days after work
The total number of days he run = 7 days
Total distance he ran in one week = 63 miles
The distance he run before the work = 3 miles
The total distance he run before the work in one week= 7×3
= 21 miles
The total distance he run after the work = 63 - 21
= 42 miles
The equation that can use to find how many mile x, Omar ran each day after work = (Total distance he ran in one week - The total distance he run before the work in one week) ÷ 7
Substitute the values in the equation
= 42/7
= 6 miles
Hence, the equation that can be use to find the how many miles, x, Omar ran each day after work is x = (Total distance he ran in one week - The total distance he run before the work in one week) ÷ 7, he ran 6 miles each days after work

The slope and equation of line with the coordinates (5,6) and (3,4) are 1 and y = x + 1 respectively.
How determine the slope of a line segment line?Slope is simply expressed as change in y over the change in x.
Slope m = ( y₂ - y₁ )/( x₂ - x₁ )
Given the data in the question;
Point A(5,6)
x₁ = 5y₁ = 6Point B(3,4)
x₂ = 3y₂ = 4Slope m = ?
To determine the slope, plug the given coordinates into the slope formula and simplify.
Slope m = ( y₂ - y₁ )/( x₂ - x₁ )
Slope m = ( 4 - 6 )/( 3 - 5 )
Slope m = ( -2 )/( -2 )
Slope m = ( -1 )/( -1 )
Slope m = 1/1
Slope m = 1
Next, use the the formula for the equation of line to determine the y-intercept 'b'.
y = mx + b
Plug in slope m = 1 and point (5,6)
6 = 1(5) + b
6 = 5 + b
b = 6 - 5
b = 1
Now that we have both the slope m ( 1 ) and y-intercept b ( 1 ), plug these values into y = mx + b to find the linear equation.
y = mx + b
y = 1x + 1
y = x + 1
Therefore, the slope is 1 and equation of line is y = x + 1.
