Answer:
[tex]\text{A)}\quad\dfrac{9}{x+y}[/tex]
Step-by-step explanation:
In the English expression, you need to understand that "A divided by B" means that A is the numerator and B is the denominator of the fraction representing the division. Here, "B" is "the quantity of ...", which means that the stuff after "of ..." is to be treated as a single item, the denominator in this case. That item is "x plus y." So, the expression in math terms is ...
[tex]\dfrac{9}{x+y}[/tex]
When this is written in plain text, the "quantity" is put in parentheses, because the fraction bar no longer serves as a grouping symbol:
9/(x+y)
These expressions match the first choice, A.

marcos reads 3 1/2 books in 1 3/4 weeks at this rate how many books does marcos read in 1 week
Answers
Answer: 2 books.
Step-by-step explanation:
The rate of doing a given activity in a given amount of time can be calculated as:
Rate = (how much you do)/(time that it takes)
In this case, we know that:
Marcos reads (3 + 1/2) books in (1 + 3/4) weeks.
then the rate is calculated as:
R = (3 + 1/2) books/(1 + 3/4) weeks
= (3 + 1/2)/(1 + 3/4) books per week.
= (6/2 + 1/2)/(4/4 + 3/4) books per week
= (7/2)/(7/4) books per week
= 4/2 books per week
= 2 books per week
This means that marcos can read 2 books in one week.
The number of books that will be read in a week will be 2 books.
From the information given, it was stated that Marcos reads 3 1/2 books in 1 3/4 weeks.
Therefore, the number of books that will be read weekly at this rate will be:
= 3.5 / 1.75
= 2

Abby is trying to pay off her debt. She owes $422 to her bank. In may she paid $76, but had to borrow an additional $135. In June she paid $45 and borrowed $110. The bank also charged her $58 in interest. How much did she owe at the end of June.
Extra points
Answers
Answer: 624
Step by Step Explanation: Subtract 422 with 76, add 135, subtract 45, add 110, and lastly add 58.
Subtract 422 with 76, 422-76=366.
Add 366 with 135, answer will be 501.
Subtract 501 with 45 since she paid $45. 501-45=456.
Add 456 with 110 and that would be 566.
For the last step add 58 to find the answer and you would get 624.
Final Result: 624.

Work out the size of angle x
Answers
Answer:
x = 66°
Step-by-step explanation:
The sum of the measures of the angles of a triangle is 180°.
x + 79° + 35° = 180°
x + 114° = 180°
x = 180° - 114°
x = 66°
x is an interior angle of triangle and according to the angle sum property of triangle measure of angle x is 66 degrees .
Given,
Triangle with interior angle.
Angle sum property: The sum of the measures of the angles of a triangle is 180°.
So,
x + 79° + 35° = 180°
Add the angles on LHS.
x + 114° = 180°
Combine like terms by taking 114 degrees from LHS to RHS .
Sign of 114 degrees will be changed to negative,
x = 180° - 114°
x = 66°
Therefore the x measures to be 66 degrees.

The country's population decreased by about 2.4% during this time period.
Since we have given that
In 1990, the number of people = 167 million
In 2010, the number of people = 163 million
We need to find the percent decrease in the country's population during this time.
Percentage would be
New - Original x 100/original
= 163 - 167/167 x 100
= -4/167 x 100
=-2.39%
=-2.4%
Hence, the country's population decreased by about 2.4% during this time period.
Type of problem: Percentage decrease
Step 1: Find the difference between the two numbers
(Difference = original number - new number)
164,000,000 - 155,000,000 = 9,000,000
Step 2: Divide the difference by the original number
9,000,000 / 164,000,000 = 0.05487804878
Step 3: Multiply by 100 and round to find the percent
0.05487804878 x 100 = 5.48780487805
Round to one place = 5.5
Answer: 5.5% decrease in the population

Step-by-step explanation:
System of equations
Kathy sells candles for $3 and flowers for $5. Let's set the following variables:
x = number of candles Kathy sells
y = number of flowers Kathy sells
She plans to sell 200 items, thus:
x + y = 200
She also likes to earn $2,500. The equation for this condition is:
3x + 5y = 2500
The system of equations is
[tex]\left\{\begin{matrix}x + y = 200\\ 3x + 5y = 2500\end{matrix}\right[/tex]

Our environment is very sensitive to the amount of ozone in the upper atmosphere. The level of ozone normally found is 5.9 parts/million (ppm). A researcher believes that the current ozone level is not at a normal level. The mean of 24 samples is 5.6 ppm with a standard deviation of 1.0. Assume the population is normally distributed. A level of significance of 0.02 will be used. Find the value of the test statistic. Round your answer to three decimal places.
Answers
Answer:
t = -0.061
Step-by-step explanation:
We are given;
Population mean; μ = 5.9
Sample mean; x¯ = 5.6
Sample size; n = 24
standard deviation; σ = 1
Significance level = 0.02
Formula for the test statistic since sample size is less than 30 is;
t = (x¯ - μ)/(σ/√n)
t = (5.6 - 5.9)/(1/√24)
t = -0.3/(1/√24)
t = -0.061

Shop owner, if the hall is of a square shape and
has a perimeter of 400m
a.Rs 400.000
b.Rs 600 000
c. 528000 d.365000
Answers
Answer:
c. 528000
Step-by-step explanation:
The computation of the amount that need to be paid is shown below:
Let us assume the side of the square shaped hall be X meter s
So,
Perimeter = 4X
Now
4X = 400
X = 100m
Now
Area of the hall = 100 × 100 = 10000 sq. meter.
And,
The cost on total tiles is
= 10,000 × 48 = Rs. 480000
But, there is 10% damage has occurred that involved in the cost
So,
Total cost is
= Rs 480,000 + 10% of 480,000
= 480,000 + 48,000
= Rs. 5,28,000
