the table shows the amount of rainfall in maryville during each week in april what was the total amount if rain in that month of april
The total amount of rainfall in Maryville for the month of April, when expressed as a mixed fraction, is 5 and 1/24 inches. Therefore the correct option is H.
Step 1: Convert mixed numbers to improper fractions
For Week 1, we have 2 2/3 inches, which is a mixed number. We convert it to an improper fraction. Since 2 is equal to 6/3, adding 2/3 gives us 8/3 inches.
Step 2: Sum up the rainfall for all weeks
Now we add the rainfall for each week:
- Week 1: 8/3 inches
- Week 2: 1/8 inches
- Week 3: 1 3/4 inches, which is the same as 7/4 inches when converted to an improper fraction.
- Week 4: 1/2 inches
Step 3: Calculate the total rainfall
The total rainfall for April is the sum of all these amounts.
Let's perform this calculation.
The total amount of rainfall in Maryville for the month of April, when summed up and expressed as an improper fraction, is \( \frac{121}{24} \) inches.
This total is reached by adding the rainfall for each week:
- Week 1's rainfall is [tex]\( \frac{8}{3} \)[/tex] inches.
- Week 2's rainfall is [tex]\( \frac{1}{8} \)[/tex] inches.
- Week 3's rainfall is [tex]\( \frac{7}{4} \)[/tex] inches.
- Week 4's rainfall is [tex]\( \frac{1}{2} \)[/tex] inches.
Adding all these fractions together gives us the total rainfall for the month.
The total amount of rainfall in Maryville for the month of April, when expressed as a mixed fraction, is 5 and [tex]\( \frac{1}{24} \)[/tex] inches.

If 2/3 of the girls have brown eyes and 1/4 of the girls have blue eyes, what fraction of the girls in class have niether blue or nrown eyes?
Answer:
1/12
Step-by-step explanation:
The fraction of the girls in class that have neither blue or green eyes is given by B = 1/12 of the girls
What is a Fraction?An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.
Given data ,
Let the fraction of the girls in class that have neither blue or green eyes be represented as B
Now , the value of B is
Let the fraction of girls in the class that have blue eyes = ( 2/3 ) of girls
Let the fraction of girls in the class that have brown eyes = ( 1/4 ) of girls
So , the total fraction A = ( 2/3 ) + ( 1/4 )
The total fraction of girls with either blue of brown eyes A = ( 11/12 ) of girls
And , fraction of the girls in class that have neither blue or green eyes is given by B = 1 - A
On simplifying , we get
The fraction of the girls in class that have neither blue or green eyes is given by B = 1 - 11/12
The fraction of the girls in class that have neither blue or green eyes is given by B = 1/12
Therefore , the value of B is ( 1/12 ) of the girls
Hence , the fraction is 1/12 of the girls

f as a function of x is equal to the square root of quantity 4 x plus 6, g as a function of x is equal to the square root of quantity 4 x minus 6
Find (f + g)(x). (5 points)
The sum (f + g)(x) of two functions f(x) = √(4x + 6) and g(x) = √(4x - 6) is determined by simply adding the two functions together, hence (f + g)(x) = √(4x + 6) + √(4x - 6).
Explanation:The functions provided are f(x) = √(4x + 6) and g(x) = √(4x - 6). The question asks for the value of (f + g)(x), which is the sum of f(x) and g(x).
To find (f + g)(x), you simply add the two functions together. Hence, (f + g)(x) = f(x) + g(x) = √(4x + 6) + √(4x - 6).
This indicates that the function (f + g)(x) is the addition of the values of f(x) and g(x) at any given value of 'x'.

8.038 x 10 to the 8th power in standard form is 803,800,000, which is obtained by moving the decimal point 8 places to the right and filling in zeros as needed.
To answer the student's question about converting 8.038 x 10 to the 8th power to standard form, we need to recognize the concept of scientific notation. When a number is written in scientific notation with a positive power of 10, like 8.038 x 108, it means the decimal point will move to the right the number of times indicated by the exponent. In this case, 8 places. So starting from 8.038, move the decimal point eight places to the right to convert it into standard form.
By doing so, we add zeros to fill in the places as we move the decimal point: 803,800,000. Therefore, 8.038 x 10 to the 8th power in standard form is 803,800,000.
