The surface area of the cylinder is approximately 191.9 square inches.

The surface area of a cylinder is the sum of the areas of its curved surface and its two circular bases. The formula for the surface area of a cylinder is:

SA = 2πr² + 2πrh

where SA is the surface area, r is the radius of the circular base, h is the height of the cylinder, and π is the mathematical constant pi (approximately equal to 3.14159).

The first term on the right-hand side of the equation (2πr²) represents the area of the two circular bases of the cylinder. The second term (2πrh) represents the area of the curved surface of the cylinder.

The area of the square embedded in the circular base of the cylinder is 18 in², which means each side of the square has a length of √18 in = 3√2 in. Since the square is embedded in the circular base, the diameter of the base of the cylinder is equal to the diagonal of the square, which is 2 times the length of one side, or 6√2 in.

The radius of the circular base is half the diameter, or 3√2 in. The surface area of the cylinder consists of the area of the top circular base, the area of the bottom circular base, and the lateral area (the curved surface area) of the cylinder.

The area of each circular base is πr² = π(3√2)² = 18π in².

The lateral area of the cylinder can be found by multiplying the height (which is given as 10 inches) by the perimeter of the circular base (which is 2πr). The perimeter of the circular base is 2π(3√2) = 6π√2 in. Therefore, the lateral area is 10(6π√2) = 60π√2 in².

The total surface area of the cylinder is the sum of the areas of the two circular bases and the lateral area:

Surface area = 2(18π) + 60π√2

= 36π + 60π√2

≈ 191.9 in² (rounded to one decimal place)

Therefore, the surface area of the cylinder is approximately 191.9 square inches.

220-22=198students

Final answer:

After subtracting Mr. Thompson's class size of 22 students from the school cafeteria's capacity of 200, 178 students can still eat in the cafeteria.

Explanation:

The student's question pertains to the capacity of the school cafeteria and how many more students can be accommodated when a specific class is having lunch. If the cafeteria holds 200 students and Mr. Thompson's class has 22 students, we can calculate the number of additional students that can still eat in the cafeteria by subtracting Mr. Thompson's class size from the total capacity of the cafeteria.

To solve this, we perform the following subtraction:

Capacity of cafeteria - Number of students in Mr. Thompson's class = Number of remaining spots

200 - 22 = 178

Therefore, 178 students can still eat in the cafeteria when Mr. Thompson's class is having lunch.

Step-by-step explanation:

3.27 Times 10⁻⁴ in standard form is 0.000327. This is found by moving the decimal point in 3.27 four places to the left, resulting in the number 0.000327.

The number 3.27 TImes  10⁻⁴ into standard form.

To do this, we move the decimal point four places to the left, because the exponent on the 10 is negative four.

So, starting with the number 3.27, we move the decimal point to the left four times, which introduces three zeros after the decimal point and before the 327.

The correct answer is B: 0.000327.

This means that 3.27 times  10⁻⁴ is equivalent to 0.000327 when written in standard form.

Slope = change in y / change in x

Y-values: 9 and 2

x-values: 3 and -4

Change is the difference

9-2)/(3- (-4)) = 7/7 = 1

Answer:

The slope is 1

Step-by-step explanation:

To find the slope, we use the formula

m = (y2-y1)/(x2-x1)

where (x1,y1) and (x2,y2) are the points on the line

m = (9-2)/(3--4)

 = (9-2) /(3+4)

Answer:

[tex]\frac{(L x M)}{6}[/tex]

Step-by-step explanation:

The greatest common factor is the greatest number that will divide two values. We have two values L and M. Each has numbers which multiply together to give the number. The highest value or most in common they share is 6. This is the GCF.

The least common multiple is the smallest positive number which is a multiple of the two. This means both L and M divide into it evenly.

We know L x M is a multiple because L and M will be factors of it. But we don't know its the least.

As an example if L= 42 and M = 60, they have GCF 6. We can multiply them to find a multiple 42 x 60 = 2520 but we don't know this is the smallest or least multiple we can find. If we divide by the GCF, 2520/6=420. Interestingly, 42 x 10 =420 and 60 x 7 =420. This means 420 is the least common multiple.

We can multiply (L x M) and then divide by the GCF of L & M to find the least common multiple.

D

Step-by-step explanation:

f(x) - g(x) = -9x^2 - 7x + 12 - (3x^2 - 4x - 15)  Remove the brackets

f(x) - g(x) = -9x^2 - 7x  + 12 - 3x^2 + 4x + 15

f(x) - g(x) = -9x^2 - 3x^2 - 7x + 4x + 12 + 15

f(x) - g(x) = -12x^2- 3x + 27

Answer D

Answer:

Option D. -12x² - 3x + 27

Step-by-step explanation:

The given functions are f(x) = -9x² - 7x + 12 and g(x) = 3x² - 4x - 15

We have to find the value of f(x) - g(x)

f(x) - g(x) = (-9x² - 7x + 12) - (3x² - 4x - 15)

              = -9x² - 7x + 12 - 3x² + 4x + 15

              = (-9x² - 3x²) - (7x - 4x) + 12 + 15

              = -12x² - 3x + 27

This value of f(x) - g(x) matches with option D.

Therefore, Option D. is the correct option.

Answer:

the answer is $8.29

Step-by-step explanation:

1.60 marked up by 60% in decimal form is .60

multiply that .60 by 1.60 and you get .64

you add .64 to 1.60 and you get 2.56

you multiply 2.56 by 3 and you get 7.68

you have a 8% sales tax so you multiply 0.08 by 7.68

you will get .61 you add that to 7.68 to get $8.29

Answer:

$6.64

Step-by-step explanation:

When the price of an item is marked up by a percentage, the new price (after markup) is result when the product of the percentage and the original price added  to the original price.

The price after markdown is similar to the mark up except that the product of the percentage and the original price is subtracted from the original price.

Hence when a box of spaghetti at the grocery store is purchased for $1.60 wholesale and is marked up by 60 percent, the new price

=60% * $1.60 + $1.60

$2.56

If the store marks down the item by 20 percent, then the new price becomes

= $2.56 - 20% * $2.56

= $2.048

If a customer wants to buy 3, the price

= $2.048 * 3

= $6.144

Including 8% tax, the price becomes

=$6.144 + 8% * $6.144

= $6.63552

The statement that most accurately represents the data given is the 'The mean and median age are more likely to be the same for the students in Math 1.'

Step-by-step explanation:

The box and whisker plots given for the two sets of data show a few different things.  Box and whisker plots first show us the median in a given set of data, which is the line in the middle of the box.  For both Math 1 and Math 2, this line occurs at 19.  The whiskers that extend from the box on either side represent the range, or lowest and highest numbers, in the data.  For Math 1, the range is 17-21 and for Math 2, the range is 17-23.  Since the range is more evenly distributed in Math 1, we can conclude that the mean, or average of the data, is most likely the same as the median of the data, which is 19.

To find the length of the wall represented by a line that is 3 7/8 inches long on the blueprint, we can use the scale conversion. The length of the wall is 15 1/2 feet.

To find the length of the wall represented by a line that is 3 7/8 inches long on the blueprint, we need to use the scale conversion.

The given scale is 1 inch corresponds to 4 feet.

So, we can set up a proportion:

1 inch − 4 feet

3 7/8 inches − x feet

To solve for x, we can cross-multiply:

1 × x = 4 × 3 7/8

Multiply 4 by the whole number 3 and then add the product to the result of 4 multiplied by the fractional part 7/8.

x = 12 + 28/8

x = 12 + 3 1/2

x = 15 1/2 feet

Therefore, the length of the wall represented by a line that is 3 7/8 inches long on the blueprint is 15 1/2 feet.

Answer: x^3y^4 is the lowest common denominator.

Step-by-step explanation: To get both expressions to have a common denominator, multiply both of them to get them equal. For the first expression, multiply the numerator and denominator by y^3: 3y^3/x^3y^4

The second expression should be multiplied by the numerator and denominator by x^2: 7x^2/x^3y^4

(Add exponents when multiplying them) Now both expressions have common denominators.

Answer:

x^3*y^4

Step-by-step explanation:

The two denominators shown are x^3*y and x*y^4.  The LCD must involve the largest power of x, which is x^3, and the largest power of y, which is y^4.  Thus, the LCD is x^3*y^4.

To calculate SUTA and FUTA for the first 12 weeks, calculate the taxable wages for each employee. Multiply the taxable wages by the respective tax rates to find the amount owed. Roger owes $371 for SUTA and $56 for FUTA for the first 12 weeks.

To calculate the amount that Roger owes for SUTA (State Unemployment Tax Act) and FUTA (Federal Unemployment Tax Act) for the first 12 weeks, we need to calculate the taxable wages for each employee. The taxable wages for SUTA is the first $7,000 and for FUTA is the first $7,000 as well.

Since the three employees earn $500, $550, and $700 respectively, their total wages for the first 12 weeks would be $17,100 (12 weeks x ($500 + $550 + $700)). However, since SUTA and FUTA only consider the first $7,000 of wages, we can calculate the amount for each tax.

For SUTA, the total taxable wages would be $7,000. Using the SUTA rate of 5.3%, we can calculate the amount owed: $7,000 x 0.053 = $371.

For FUTA, the total taxable wages would also be $7,000. Using the FUTA rate of 0.8%, we can calculate the amount owed: $7,000 x 0.008 = $56.

Therefore, Roger owes $371 for SUTA and $56 for FUTA for the first 12 weeks for his three employees.

Answer:

c = 0.6d + 1.2

Step-by-step explanation:

Use distance as the independent variable and cost as the dependent variable. Each point (x, y) is (distance, cost).

The 3 mile ride for $3.00 gives you point (3, 3).

The 6 mile ride that cost $4.80 gives you point (6, 4.8).

Now you need to find the equation of the line that passes through points

(3, 3) and (6, 4.8).

y = mx + b

m = slope = (y2 - y1)/(x2 - x1) = (4.8 - 3)/(6 - 3) = 1.8/3 = 0.6

Use point (3, 3).

y = 0.6x + b

3 = 0.6(3) + b

3 = 1.8 + b

b = 1.2

The equation is

y = 0.6x + 1.2

Use c for cost and d for distance to get

c = 0.6d + 1.2

Answer:

There are 8 cans on each of the equal shelves

Step-by-step explanation:

Total number of cans put in display = 35

Shelves with equal no of cans =  4 Shelves

And one shelf displays only 3 cans

Therefore, 4 shelves with equal no of cans + 1 shelf with 3 cans = 35 cans

Let us assume equal no. of cans be x

We get, 4x + 3 = 35

             4x = 35 - 3

             4x = 32

              x  = 32 ÷ 4

              x = 8

Thus, 4 shelves with equal no of cans contains 8 cans each.
