a package of aluminum foil contains 50. ft2 of foil, which weighs approximately 9.0 oz . what is the approximate thickness of the foil in millimeters?
The approximate thickness of the package of aluminum foil with given density and weight is equal to 0.002 millimeters.
1 ft = 30.48 cm
Area of aluminum foil = 50 ft²
= 50 × ( 30.48 )² cm²
= 46451.52 cm²
1 oz = 28.3495 grams
Weight of the aluminum = 9.0 oz
= 255.1455 grams
Density = 2.70 g/cm³
Density = weight / ( area × thickness )
⇒ Thickness = weight / ( area × density )
⇒Thickness = 255.1455 grams / ( 46451.52 cm² × 2.70 g/cm³ )
⇒Thickness = 0.00203
⇒Thickness = 0.002 millimeters
Therefore, approximate thickness of the aluminum foil is equal to 0.002 millimeters.
The above question is incomplete, the complete question is:

Answer:
The answer is D.
Step-by-step explanation:
8/5w = 40
Simplify your answer as much as possible.
Answer:
w = 25
Step-by-step explanation:
8/5w = 40
Divided both sides by 8/5
w = 25
Let's check
8/5(25) = 40
40 = 40
So, w = 25 is the correct answer.
Answer: w = 25
Step-by-step explanation:
To solve for w, we will isolate the variable by using inverse operations.
Given:
[tex]\displaystyle \frac{8}{5} w=40[/tex]
Divide both sides of the equation by [tex]\frac{8}{5}[/tex]:
* Note: w is being multiplied by [tex]\frac{8}{5}[/tex], so the inverse operation is division
[tex]\displaystyle w=\frac{40}{\frac{8}{5 } } \mapsto w=40*\frac{5}{8} \mapsto w=*\frac{40*5}{8} \mapsto\frac{200}{8} \mapsto \boxed{w=25}[/tex]
Michael is 3 times as old as Brandon. 18 years ago, Michael was 9 times as old as Brandon.
How old is Michael now?
Currently, Michael is 72 years old
How old is Michael now?Let's represent Michael's current age as "x".
Then Brandon's current age is x/3.
18 years ago, Michael's age was x-18
Brandon's age was x/3-18.
18 years ago, we can write the equation:
x - 18 = 9 * (x/3 - 18)
So, we have
x - 18 = 3x - 162
Evaluate the like terms
2x = 144
Divide by 2
x = 72

What is the measure of angle A?
The measure of angle A is calculated by applying the following formula as shown below;
If line AB is similar to line AC, then angle B must be equal to angle C.
∠ B = ∠ C = 40 ⁰
The value of angle A is calculated as follows;
∠ A = 180⁰ - ( ∠ B + ∠ C ) ( sum of angles in a triangle )
∠ A = 180⁰ - ( 40⁰ + 40⁰ )

Zero
Negative
Larger than the variance
Which of the following statements is true:
a. (i) & (ii)
b. (ii) & (iii)
c. (i), (ii) & (iii)
d. None of the above
The numerical value of the standard deviation is never (B) less than the variance and is never negative.
What is the standard deviation?The standard deviation is a statistic that expresses how much variance or dispersion there is in a group of numbers.
While a high standard deviation suggests that the values are dispersed over a wider range, a low standard deviation suggests that the values tend to be close to the mean (also known as the anticipated value) of the collection.
The standard deviation's numerical value is always greater than the variance and can never be negative.
The lowercase Greek letter (sigma), for the population standard deviation, or the Latin symbol s, for the sample standard deviation, are most frequently used in mathematical texts and equations to indicate standard deviation.
Standard deviation may be written as SD.
Therefore, the numerical value of the standard deviation is never (B) less than the variance and is never negative.

Is the trapezoidal rule an overestimate or underestimate?
The trapezoidal rule is a numerical integration method that frequently overestimates the real value of a function's definite integral.
What is trapezoidal rule?The trapezoidal rule is a strategy for approximating the definite integral in calculus. The trapezoidal rule works by computing the area of the region under the graph of the function f(x) that is approximated as a trapezoid. The trapezoidal rule is commonly used to calculate the area under curves. This is achievable if the overall area is divided into smaller trapezoids rather than rectangles. The Trapezoidal Rule integration determines the area by approximating the area under a function's graph as a trapezoid. The midway rule uses rectangular areas to approximate the definite integral, whereas the trapezoidal rule uses trapezoidal approximations to approximate the definite integral. Simpson's approach works by first approximating the original function with piecewise quadratic functions.

Find the mean absolute deviation for the set below 108, 53, 47, 22, 56, 62
Answer: The mean absolute deviation for the given data set is 19.
Step-by-step explanation:
The mean absolute deviation (MAD) is a measure of the variability of a set of data and is defined as the average of the absolute deviations of each data point from the mean. To find the MAD, we first need to find the mean of the data set, and then subtract each data point from the mean and take the absolute value of the result.
Here is the step-by-step process for finding the MAD for the given data set:
Find the mean of the data set: (108 + 53 + 47 + 22 + 56 + 62) / 6 = 56
Subtract the mean from each data point:
108 - 56 = 52
53 - 56 = -3
47 - 56 = -9
22 - 56 = -34
56 - 56 = 0
62 - 56 = 6
Take the absolute value of each result:
|52| = 52
|-3| = 3
|-9| = 9
|-34| = 34
|0| = 0
|6| = 6
Find the average of the absolute deviations: (52 + 3 + 9 + 34 + 0 + 6) / 6 = 19
So the mean absolute deviation for the given data set is 19.

Which is a radius and which is a diameter?The distance between a circle's center and periphery is referred as the radius. Always, the diameter is twice the radius. As a conclusion, the diameter is multiplied by two to obtain the formula.
Diameter and circumference are what?The ratio of a circle's circumference to diameter serves as the basis for the traditional definition of Pi (). The diameter or length of such a circle is its circumference. A straight line connecting a point on one end of both the ring to a place on the opposite end, through the center, is the diameter.
Diameter = 2r -----------(1)
where r is the radius
The value of the diameter = 32 m and radius is given to be 4(x+5)
substitute the above into equation (1) and then solve for x
32 = 2 [ 4(x + 5)]
first open the inner bracket
32 = 5[4x + 20}
then open the outer bracket
32 = 20x + 100
subtract 16 from both-side of the equation
20x=100-32
20x=68
x=3.4
Divide both-side of the equation by 3.4
16/3.4 = 8x/3.4

x = 4.70
Therefore, the value of x is 4.70

In light of the query we've got D)x + y ≤ -2 and 2x - 3y ≤ -9 is a pair of inequalities for (-3, 1) is the correct answer.
How may an inequality be resolved?When resolving an inequality, you can do one of the following: · Add a same number to each side; • Subtract the same amount from each side; • Multiply or divide either aspect by the exact positive amount. You must flip the inequality sign if you combine or split each end by a negative number.
According to the values x = -3, y = 1
-3 + 1 = -2, which is less than or equal to -2, so the first inequality is true.
2 * -3 - 3 * 1 = -9, which is less than or equal to -9, so the second inequality is also true.
Since both inequalities are true, (-3, 1) is a solution for the system of inequalities x + y ≤ -2 and 2x - 3y ≤ -9.
