How many books does Matt have to sell to make $30 for the week?
Matt needs to sell approximately 28 books to make $30 for the week.
To find the number of books Matt needs to sell to make $30 for the week, we need to use the given information that Matt gets $6 for selling 9 books and $9 for selling 11 books.
Let's first find the amount of money Matt makes for each book:
For 9 books, Matt makes $6, so he makes $\frac{6}{9} = \frac{2}{3}$ dollars per book.
For 11 books, Matt makes $9, so he makes $\frac{9}{11}$ dollars per book.
Now, we can set up an equation to find the number of books Matt needs to sell to make $30:
2/3 x + 9/11 x=30
where (x) is the number of books Matt needs to sell.
Simplifying the equation, we get:
x = 28
Therefore, Matt needs to sell approximately 28 books to make $30 for the week. Since he cannot sell a fraction of a book, he would need to sell either 28 or 29 books to make $30.

This square has the hypotenuse of a right triangle as one of its sides.
The estimated value of the length of the hypotenuse is units. The estimated value of the area of the square is square units.
(Hint: The hypotenuse is the side opposite the right angle. To find the hypotenuse of a right triangle, use the Pythagorean Theorem, c2= a2 + b2.)
The question is about using the Pythagorean Theorem to calculate the length of the hypotenuse of a right triangle. It also asks how to calculate the area of a square when the hypotenuse of the right triangle is one of its sides. The hypotenuse's length would be useful to determine the square's area, as the square's area is calculated as the square of the length of one side.
Explanation:The subject of this question is Mathematics, and it is appropriate for a High School level student. The question is discussing a scenario where a square has the hypotenuse of a right triangle as one of its sides, and the student is asked to estimate the value of the length of the hypotenuse and calculate the area of the square.
To solve this problem, we will use the Pythagorean Theorem, which states that in a right triangle, the square of the length of the hypotenuse (let's call it 'c') is equal to the sum of the squares of the lengths of the other two sides (let's call them 'a' and 'b'). In other words, c² = a² + b². The length of the hypotenuse is the square root of this sum, √(a² + b²).
Since we aren't given specific lengths for the sides of the triangle, I cannot provide exact values. However, let's say that the length of the hypotenuse is 'd', then the area of the square, which is calculated as the length of one side squared (d²) would be equal to the given value.

Fiona and her friends went to a smoothie shop. They ordered three strawberry smoothies and two protein shakes for a total of $24.00. Last week they ordered one strawberry smoothie and four protein shakes for a total of $25.50. The system that represents their purchases is below. x + 4y = 25.50 3x + 2y = 24.00 What is the price of a protein shake? $3.75 $4.50 $4.95 $5.25
Answer: Fourth option is correct.
Step-by-step explanation:
Since we have given that
[tex]x+4y=25.50------------------(1)\\\\3x+2y=24.00-----------------------(2)[/tex]
Here, x is the number of strawberry smoothies.
and y is the number of protein shakes.
So, using elimination method, we get that,
Multiplying 2 by eq(2), we get that
6x+4y=48---------------(3)
From eq(1) and (3), we have
[tex]x+4y=25.50\\\\6x+4y=48\\\\-----------------------------------\\\\-5x=-22.5\\\\x=\dfrac{22.5}{5}\\\\x=4.5[/tex]
Put the value of x in eq(1), we get that
[tex]4.50+4y=25.50\\\\4y=25.50-4.50\\\\4y=21\\\\y=\dfrac{21}{4}\\\\y=5.25[/tex]
Hence, the price of protein shake is $5.25.
Thus, Fourth option is correct.

what does this expression represent 12f+24
Answer:
This is an algebraic expression which means that 12 multiplied by the value of a variable "f", plus 24 would give an integer.
Step-by-step explanation:
This expression can be solved when the value of f is known. Thus its solution is dependent on the known value of "f".
So, assuming the value of f is 2, then the answer would have been 48.

The required number to represent the situation is 67/24.
What is the ratio of two numbers?The ratio of two numbers a and b can be written as a : b = a/b.
The ratio of two quantities is the unit rate of one quantity with respect to the other.
Given that,
The cloth required for jacket is 1(⁵/₈) = 13/8 yards.
Then the remaining cloth for the three other items = 10 - 13/8 = 67/8 yards.
Now, the cloth for each of the items is calculated by taking the ratio as,
(67/8)/3
= 67/24
Hence, the yards of cloth available for each of the item is given as 67/24 yards.

Below are two different functions, f(x) and g(x). What can be determined about their slopes? f(x) George reads 200 pages in 40 minutes. x g(x) 4 −8 4 10 4 28
Therefore, since the slope of f(x) is defined and g(x) has an undefined slope, the correct option is: d) The function f(x) has a larger slope.
To determine the slopes of the functions f(x) and g(x), we need to calculate the rate of change or the slope of each function.
The slope of a function represents how much the output (y-value) changes for a given change in the input (x-value).
For function f(x), the rate of change can be calculated as follows:
[tex]\[ \text{Slope of } f(x) = \frac{\text{Change in } y}{\text{Change in } x} = \frac{200 \text{ pages}}{40 \text{ minutes}} = 5 \text{ pages/minute} \][/tex]
Now, let's calculate the slope for function g(x) using the given data points:
[tex]\[ \text{Slope of } g(x) = \frac{\text{Change in } y}{\text{Change in } x} = \frac{28 - (-8)}{4 - 4} = \frac{36}{0} \][/tex]
As the denominator is zero, the slope for g(x) is undefined.
