Final answer:
The division of $7.59 by 2.2 results in approximately 3.45. This can be calculated using long division or a calculator after adjusting for the decimal in the divisor.
Explanation:
The student has asked how to divide the number $7.59 by 2.2. This is a basic arithmetic operation involving division. To perform this division, you can use long division or a calculator. When you divide $7.59 by 2.2, you will get approximately 3.45, which is the quotient. Here's a step-by-step breakdown:
Set up the division with $7.59 as the dividend and 2.2 as the divisor. Since we are dividing by a decimal, we can move the decimal point of the divisor (2.2) to the right to make it a whole number (22). Simultaneously, we also move the decimal point in the dividend (7.59) the same number of places to the right, changing it to 759. Now, divide 759 by 22 using long division or a calculator. The result is approximately 34.5, but since we moved the decimal one place to the right, we must move it back one place to the left in our answer, resulting in 3.45.A book sold 32,500 copies in its first month of release.

Niall owes $187 to his cousin. However, he doesn't have any money right now. He hopes to earn some money by painting a house. He gets paid $34 for every 2 hours he paints. Which equation of a line models y, the amount of money he will have after paying back his cousin, in terms of x, the number of hours he spends painting?
Answer:
[tex]y=17x-187[/tex] where x>11
Step-by-step explanation:
Niall gets $34 for 2 hours.
So, he gets [tex]34/2=17[/tex] dollars per hour.
Now, he owes $187 to his cousin.
Let the number of hours he works be = x
Let the money left with him after paying his cousin be = y
So, the equation forms:
[tex]y=17x-187[/tex]
Rather we can say it is :
[tex]y=17x-187[/tex] where x>11
If we want to know how many hours are needed to pay the debt, we can consider y = 0
[tex]17x-187=0[/tex]
[tex]17x=187[/tex]
[tex]x=187/17[/tex]
So, x = 11 hours
So, Niall needs 11 hours of work to pay back his cousin and after that all his earnings is 'y'. When x>11 then 'y' will have some money left.

It cost $3.99 for 25 fl. oz. of detergent or $6.99 for 90 fl. oz. Which is a better buy?
$6.99 for 90 fl. oz of detergent is a better buy.
Arithmetic operations is a concept that concerns the study of mathematical operations like addition, subtraction, division, and multiplication.
The determination on the type which is a better buy can be estimated by finding the cost of each detergent in the two cases.
For the first case, we are being told that It cost $3.99 for 25 fl. oz. of detergent.
From that, the price for 1 fl. oz will be:
[tex]\mathbf{x = \dfrac{3.99 \times 1 }{25}}[/tex]
x = $0.1596
For the second case, if the price for 90 fl. oz is $6.99
For 1 fl.oz, we have:
[tex]\mathbf{x = \dfrac{6.99 \times 1 }{90}}[/tex]
x = $0.0777
Therefore, we can conclude that $6.99 for 90 fl. oz of detergent is a better buy since the amount of each detergent is lesser than that of 25 fl. oz.

A square garden with a side length 150 m has a square swimming pool in very center with a side length 25 m .Calculate the area of the garden.
Final answer:
Calculate the area of a square garden with a swimming pool in the center.
Explanation:
The area of the garden can be calculated by finding the area of the square garden and subtracting the area of the square swimming pool.
Area of the square garden:
Area = side length × side length
= 150 m × 150 m = 22500 m²
Area of the swimming pool:
Area = side length × side length
= 25 m × 25 m = 625 m²
Area of the garden: 22500 m² - 625 m² = 21875 m²
Therefore, the area of the garden is 21875 m².

what is one third plus one fourth equal to a mixed number
The mixed number equivalent to 7/12 is 0 and 7/12.
To add one-third and one-fourth, we need to find a common denominator. The least common multiple of 3 and 4 is 12.
Converting both fractions to have a denominator of 12:
1/3 = 4/12
1/4 = 3/12
Now, we can add the fractions:
4/12 + 3/12 = 7/12
The sum of one-third and one-fourth is 7/12. To express this as a mixed number, we need to divide the numerator (7) by the denominator (12):
7 ÷ 12 = 0 remainder 7
Therefore, the mixed number equivalent to 7/12 is 0 and 7/12.

Select True or False. The expression 4x − 2(5x − 1) is equivalent to the expression 2 + 6x.
Answer: The given statement is FALSE.
Step-by-step explanation: We are given to check whether the following statement is True of False :
"The expression 4x − 2(5x − 1) is equivalent to the expression 2 + 6x".
We will be using the following distributive property :
[tex]a(b+c)=ab+ac.[/tex]
We have
[tex]4x-2(5x-1)\\\\=4x-10x+2\\\\=-6x+2\\\\=2-6x\\\\\neq 2+6x.[/tex]
Therefore, expression 4x − 2(5x − 1) is NOT equivalent to the expression 2 + 6x.
Thus, the given statement is FALSE.
