The fraction which is recommended as value of iron in 1 cup of oatmeal as per the given relation is equal to 2/15.
As given in the question,
Daily recommended value of iron in the given cup of oatmeal
3 / 4 cup of oatmeal gives 1/10 daily value of iron.
Fraction recommended as daily value of iron is given by :
⇒ 3 /4 cup of oatmeal = 1 /10 value of iron
⇒ 1 cup of oatmeal = ( 1 × 4 ) / ( 3 × 10 ) value of iron
⇒ 1 cup of oatmeal = ( 4 ) / ( 30 ) value of iron
⇒ 1 cup of oatmeal = ( 2 ) / ( 15 ) value of iron
Therefore, the fraction recommended as daily value of iron is equal to
( 2/15 ).
The above question is incomplete, the complete question is :
In 3/4 cup of oatmeal, there is 1/10 of the recommended daily value of iron. What fraction of the daily recommended value of iron is in 1 cup of oatmeal? ( multiplication and division equation)

Nathan buys a bottle of water for $1.25, gum for $0.50, and a book for $3.95. the sales tax is 10%. what is the sales tax for the things he buys
Answer:
$0.75, which is
75 cents
Step-by-step explanation:
First add the cost of all the items.
1.25 + .50 + 3.95
= 5.70
To find 10% of 5.70, change the percent to a decimal and multiply.
10% is .10
5.70 × .10 = .57
The tax is 57 cents. This can be written as $0.57

The sine, cosine, cosecant, and secant functions have period _______; the tangent and cotangent functions have period _______.
The sine, cosine, cosecant, and secant functions have period 2π; the tangent and cotangent functions have period π.
Definition for Period of a Trigonometric Function :
The pause between any function's repetitions is known as the function's period. The duration of one complete cycle is the period of a trigonometric function. Trigonometric functions include three basic types: sin, cos, and tan, which have periods of -2π, 2π, and π respectively.
If a function repeats itself repeatedly at a predetermined frequency, it is said to be periodic. The formula for t is f(x) = f(x + p), where p is a real number that denotes the period of the function. Period is the interval between two occurrences of the wave.

Write an equation of the line passing through the point (8, 2) that is parallel to the line 6x - 9y = -7.
The equation passing through the point ()8, 2 and parallel to 6x - 9y = -7 is y = 6 / 7x - 2 / 7
How to find equation of a line?The equation of the line passes through the point (8, 2) and it is parallel to 6x - 7y = -7.
The equation of a line can be represented as follows;
y = mx + b
where
m = slope
b = y-intercept
Therefore, parallel line have the same slope.
6x - 7y = -7
7y = 6x + 7
y = 6 / 7 x + 1
m = 6 / 7
Hence, using (8, 2)
2 = 6 / 7 (8) + b
2 = 16 / 7 + b
b = 2 - 16 / 7
b = 14 - 16/ 7

Based on the calculations, the true statements are:
A. The angular velocity is 10π rad/sec.
E. The angular velocity is 600π rad/min.
How to calculate the angular velocity?Mathematically, angular velocity can be calculated by using this formula:
ω = θ/t
Where:
ω is the angular velocity.θ is the angle.t is the time.Note: 1/2 revolution = 0.5 × 2π = π radians.
Substituting the given parameters into the formula, we have;
ω = θ/t
ω = π/0.1
ω = 10π rad/s.

1. What is the approximate area of circle A?
2. What is the approximate area of circle B?
3. What is the approximate area of the shaded region 1 (between the square and circle A)?
4. What is the approximate area of shaded region 2 (between circles A & B)?
The approximate area of circle A is π · 8² = 64π ≈ 201.062 square inches.
The approximate area of circle B is π · 4² = 16π ≈ 50.265 square inches.
The approximate area of shaded region 1 is 24² - 64π ≈ 374.938 square inches.
The approximate area of shaded region 2 is 64π - 16π = 48π ≈ 150.796 square inches.
How to estimate geometric areas
In this situation we have a square whose side length is known and two circles whose radii have to be estimated. By direct inspection we find that the diameter of circle A is two thirds of the length of the square side (l), in inches and the diameter of circle B is the half of the diameter of the former. Now we proceed to find the key dimensions of the figure:
Circle A
Diameter: 16 inches
Radius: 8 inches
Circle B
Diameter: 8 inches
Radius: 4 inches
The approximate area of circle A is π · 8² = 64π ≈ 201.062 square inches.
The approximate area of circle B is π · 4² = 16π ≈ 50.265 square inches.
The approximate area of shaded region 1 is 24² - 64π ≈ 374.938 square inches.

The line plot shows the prices of sunglasses at a department store.
a. Find the mean, median, and mode.
b. Which measure best describes the data? Why?
c. Which measure might be misleading in describing the average price of sunglasses? Explain your reasoning.
The measure that best describes the data is the median and the measure that might mislead the data is the mode
How to determine the mean, median and mode?The mean is calculated as:
[tex]\bar x = \frac{\sum fx}{\sum f}[/tex]
So, we have:
[tex]\bar x = \frac{20* 2 + 50 * 3 + 60 * 6 + 70 * 3 + 80 * 4 + 90 * 4 + 100 * 2 + 130 * 1}{25}[/tex]
This gives
[tex]\bar x = \frac{1770}{25}[/tex]
[tex]\bar x = 70.8[/tex]
So, the mean is 70.8
The median is the middle number, and the position is calculated using
Median = (n + 1)/2 th
This gives
Median = (25 + 1)/2 th
Median = 13th
The 13th element is 70
So, the median is 70
The mode is the data element with the highest frequency.
So, the mode is 60
The measure that best describes the dataThe line plot has outliers at 20 and 130.
This is so because 20 and 130 are far from other data values
When a dataset has an outlier, the best measure is the median
Hence, the measure that best describes the data is the median.
The measure that might mislead the dataThe measure that might mislead the data is the mode
This is so the highest occurring value does not necessarily represent the dataset
