Ronald will need 128π square feet to paint all the surfaces of the 8 Columns.

The formula for the total surface area of a cylinder is given by:

A = 2πr(r + h)

Where r is the radius and h is the height

In this case, each wooden cylindrical columns is 7 feet tall and have a diameter of 2 feet. Thus:

r = 2/2 = 1 feet and h = 7 feet

Thus, the total surface area of each wooden cylindrical columns will be:

A = 2π * 1 * (1 + 7)

A =  2π * 1 * 8

A = 16π square feet

Then the total surface areas of all the 8 Columns will be:

A = 8 * 16π

A = 128π square feet

Marcus jogged approximately 2 1/2 miles over the weekend.

We need to discover a common denominator to add the miles run on Saturday and Sunday. Because 10 is the least common multiple of 5 and 2,

we may convert the fractions to have a denominator of 10:

1 2/5 = 1 + 4/5 = 5/5 + 4/5 = 9/5

9/10 = 0.9 = 9/10

Now we can add the two distances:

9/5 + 9/10 = 18/10 + 9/10 = 27/10

Rounding 27/10 to the nearest 1/2 gives:

27/10 ≈ 2 1/2

The estimate the number of pieces of food collected by mice is 96 and closest estimate to 24 is given by option b. 20.

Number of pieces of food collected by mice every day = 24 pieces

Total number of days mice collects the food = 4 days

To estimate the total number of pieces of food collected,

Now, multiply the number of pieces collected each day by the number of days,

Total number of pieces

= 24 pieces/day × 4 days

= 96 pieces

To estimate the answer closest to 24, we can round 24 to the nearest tens.

The nearest tens to 24 is 20.

Therefore, the estimate of collection of food pieces in 4 days by mice is equal to 96 and the closest estimate to 24 is option b. 20.

The x-intercepts for the function y = cos x, where 0≤x≤ 2n are

x = π/2, x = 3π/2, and x = 2π

We have,

The cosine function has an x-intercept whenever it crosses the x-axis, which happens at every multiple of π/2 radians (or 90 degrees).

Find the complete question below.

The number of adult that paid is 234 and the number of seniors that pad is 60.

A movie theatre charges 11$ for adults and 9$ for seniors. On a particular day when 294 people paid an admission, the total receipts were 3114.

Therefore, let's find how many paid for adult and for seniors.

Let

x = number that paid for adult

y = number that paid for senior

Hence, the situation forms the following equation.

x + y = 294

11x + 9y = 3114

multiply equation(i) by 11

11x + 11y = 3234

11x + 9y = 3114

subtract the equation

2y = 120

y = 120 / 2

y = 60

Let's find x

x = 294 - 60

Answer:

C

Step-by-step explanation:

To find the sum of the rational expressions, we need to add the two expressions and simplify if possible:

(2x-1)/(7x+x+2) + (x-2)/(8x-2)

Simplifying the denominators, we get:

(2x-1)/(8x+2) + (x-2)/(8x-2)

Now, we need to find the LCD, which is (8x+2)(8x-2) = 64x²-4:

[(2x-1)(8x-2) + (x-2)(8x+2)] / (64x²-4)

Simplifying the numerator, we get:

[16x²-4x-16x+4+8x²-2x+16x-4] / (64x²-4)

Combining like terms, we get:

(24x²-2) / (64x²-4)

Factoring out a 2 from the numerator and denominator, we get:

2(12x²-1) / 2(32x²-2)

Simplifying further, we get:

(12x²-1) / (16x²-1)

Therefore, the sum of the rational expressions is:

12x²-1

Therefore, the other three clerks must finish the remaining 60% of the reports.

Total reports to be completed by the other clerks = 0.60 x 15 = 9 reports

We may distribute the remaining reports evenly among the other clerks since they all have an equal number of reports to complete:

The appropriate measure of variability for this data set is the IQR, and its value is 2. The mean and median are measures of central tendency, not measures of variability. The range may not be the best measure of variability for this data set because it is influenced by extreme values.

The given data set is:

2, 10, 10, 12, 12, 20

To determine the appropriate measure of variability, we need to consider the spread or dispersion of the data. In this case, we can see that the range,

20 - 2 = 18.

A better measure of variability for this data set is the interquartile range (IQR), which is the range of the middle 50% of the data. To find the IQR, we first need to find the median of the data:

2, 10, 10, 12, 12, 20

The median is the middle value when the data set is arranged in order, which is 11. We can then divide the data set into two halves:

2, 10, 10 and 12, 12, 20

The lower half has a median of 10, and the upper half has a median of 12. The IQR is the difference between these medians:

IQR = 12 - 10 = 2

Therefore, the appropriate measure of variability for this data set is the IQR, and its value is 2. The mean and median are measures of central tendency, not measures of variability. The range may not be the best measure of variability for this data set because it is influenced by extreme values.

To achieve equity between Equation A and Equation B, one must:

Via combining 1 with the parenthesis of Equation A and conjoining common terms, one begins by distributing the 1 and fusing both sides together to form 5x + 4 = -3.

Answer:r=3cscθ

Step-by-step explanation:The equation y = 3 represents a horizontal line at a distance of 3 units above the x-axis in the Cartesian coordinate system. To convert this equation into polar form, we can use the fact that x = rcos(theta) and y = rsin(theta) in polar coordinates.

Since y = 3 for all values of x, we can say that r*sin(theta) = 3. Solving for r, we get:

r = 3/sin(theta)

This equation represents a family of circles with center at the origin and radius 3/sin(theta), for all values of theta except for multiples of pi. We can simplify this equation by using the identity sin(theta) = 1/csc(theta), giving us:

r = 3csc(theta)

The amount of dry ingredients used in the cake recipe is approximately 7 cups.

To find the total amount of dry ingredients used in the cake recipe, we need to add up the amounts of flour, sugar, and cocoa.

3 ½ cups of flour is equal to 3 cups plus 0.5 cups, or 3 cups and 8 ounces.

2 ⅔ cups of sugar is equal to 2 cups plus 0.67 cups, or 2 cups and 10.72 ounces.

1 ¾ cups of cocoa is equal to 1 cup plus 0.75 cups, or 1 cup and 12 ounces.

Adding these amounts together, we get:

3 cups and 8 ounces + 2 cups and 10.72 ounces + 1 cup and 12 ounces = 6 cups and 14.72 ounces

Jenny earns $36 in interest in one year in her savings account.

To calculate the interest that Jenny earns in one year on her savings account, we can use the formula for simple interest:

where I is the interest earned, P is the principal amount (in this case, $1200), r is the interest rate (in decimal form), and t is the time period (in years).

In this case, the interest rate is 3% per year, which can be written as 0.03 in decimal form. The time period is one year. So we have:
