The total surface area of a cylinder is the sum of the areas of its top and bottom circles, along with the area of its lateral surface (the curved surface that connects the two circles).

The formula for the lateral surface area of a cylinder is:

Lateral surface area = 2πrh

where r is the radius of the cylinder, h is the height of the cylinder, and π (pi) is a mathematical constant approximately equal to 3.14.

The formula for the area of a circle is:

Area of circle = πr^2

Using these formulas, we can calculate the total surface area of the cylinder as follows:

Area of top and bottom circles = 2 × π × r^2

= 2 × 3.14 × 2^2

= 25.12 square feet

Lateral surface area = 2 × π × r × h

= 2 × 3.14 × 2 × 6

= 75.36 square feet

Total surface area = Area of top and bottom circles + Lateral surface area

= 25.12 + 75.36

= 100.48 square feet

Therefore, the total surface area of the cylinder is 100.48 square feet.

Step-by-step explanation:

The trignometric equation h = (32 inches) x tan(35°) can be used to solve for the height, h, of the television screen.

We can use trigonometry to solve for the height, h, of the television screen. From the given information, we can form a right triangle with the diagonal of the television screen as the hypotenuse, and the height of the screen as one of the legs.

Since we are given the angle between the diagonal and the bottom of the television, we can use the trigonometric function tangent to relate the height and the diagonal.

The equation we can use to solve for the height is:

tan(35°) = [tex]\frac{h }{ (32 inches)}[/tex]

Rearranging this equation, we get:

h = (32 inches) x tan(35°)

Therefore, the equation that can be used to solve for the height, h, of the television screen is:

h = (32 inches) x tan(35°)

So, the equation h = (32 inches) x tan(35°) can be used to solve for the height, h, of the television screen.

Let's represent the width of the rectangular course as $w$. Then the length of the rectangular course can be represented as $2w$, since the ratio of the length to the width is given as 2:1.

We know that the total length of the course is 2.4 kilometers, so we can write an equation:

$\sf\implies\:2w + 2(2w) = 2.4$

Simplifying the equation:

$\sf\implies\:6w = 2.4$

$\sf\implies\:w = \frac{2.4}{6}$

$\bigstar\implies\sf{\textbf{\boxed{w = 0.4}}}$

Therefore, the width of the course is 0.4 kilometers.

The length of the course is $\sf\:2w = 2(0.4)=$

${\boxed{\sf{0.8 kilometers.}}}$

Hence, the length of the course is 0.8 kilometers and the width of the course is 0.4 kilometers.

The road with alternating white and black stripes and each 50 cm wide is 7.5 m wide.

The road consists of alternating white and black stripes

No. of white stripes = 8

As the first and last stripe is white so in between the black stripes will be 7

No. of black stripes = 7

Total no. of stripes = 15

Width of black stripe = 50 cm

Width of white stripe = 50 cm

Width of whole road = total no. of stripes × width of each stripe

Width of whole road = 15 × 50

Width of whole road = 750 cm

To convert m into cm

Now, 1 m = 100 cm

1 cm = 1/100 m

750 cm = 750/100 m

750 cm = 7.5 m

Hence the width of the road is 7.5 m

The length of the minor arc GD is approximately 0.196π units.

To get the length of the minor arc GD, we need to subtract the measure of the major arc mDUG from the circumference of the circle, and then divide by 360° to find the length of one degree of arc.
First, we need to find the circumference of the circle. Since GA = 29, we know that the radius of the circle is also 29. The formula for the circumference of a circle is C = 2πr, so for this circle we have: C = 2π(29) = 58π
Next, we need to subtract the measure of the major arc mDUG from the circumference of the circle. Since mDUG = 185°, we have:
58π - (185/360)(58π) = (175/360)(58π)
Simplifying this expression, we get: (175/360)(58π) = 29(175/72)π ≈ 70.48π
Finally, we divide this value by 360° to find the length of one degree of arc:
(70.48π)/360 ≈ 0.196π
Therefore, the length of the minor arc GD is approximately 0.196π units.

It takes approximately 10 hours for the drug concentration to decrease.

We can use exponential decay to model the concentration of the drug in the bloodstream. Let C(t) be the concentration of the drug in milligrams at time t in hours since the person took the drug. Then we have:

[tex]C(t) = 125(0.7)^t[/tex]

where 0.7 is the factor by which the concentration decreases each hour.

We want to find the time t such that C(t) = 1. Substituting this into the equation above, we get:

[tex]1 = 125(0.7)^t[/tex]

Dividing both sides by 125, we get:

[tex]0.008 = (0.7)^t[/tex]

Taking the logarithm of both sides with base 0.7, we get:

[tex]t = log(0.008) / log(0.7)[/tex]

Carl will be charged 7.84% of the initial loan amount as interest.

When taking out a loan, it's important to understand the interest rate and how it will affect the total amount you will owe. In this case, Carl's loan accrues interest at a flat rate of 1.96% per quarter. This means that every quarter, Carl will be charged 1.96% of the initial loan amount as interest.

To determine the equivalent yearly simple interest rate, we use the formula: Yearly interest rate = Quarterly interest rate x 4. This formula works because there are four quarters in a year, so we can multiply the quarterly interest rate by four to get the annual interest rate.

In this case, the quarterly interest rate is 1.96%. Multiplying this by four, we get an annual interest rate of 7.84%. This means that over the course of a year, Carl will be charged 7.84% of the initial loan amount as interest.

Understanding the interest rate is important because it can significantly impact the total amount that you will owe on a loan. A higher interest rate means that you will pay more in interest over the life of the loan, which can make the loan more expensive overall.

By calculating the equivalent yearly simple interest rate, Carl can better understand how much he will owe in interest over the course of the loan and make an informed decision about whether or not to take out the loan.

Sure. Here is the equation for the cost, C, after h hours of babysitting:

```

C = 3 + 5h

```

This equation can be found by combining the flat fee of $3 with the hourly rate of $5. For example, if Nicole babysits for 2 hours, she will make $3 + (2 * $5) = $13.

To find how much Nicole will make after babysitting for 8 hours, we can simply substitute h = 8 into the equation. This gives us:

```

C = 3 + 5(8) = 3 + 40 = $43

```

Therefore, Nicole will make $43 after babysitting for 8 hours.

Answer:c= 3 + 5(8)

Step-by-step explanation:

3 is flat fee, and then plus $5 and hour. you know she's going for 8 hours, so you multiply hourly rate by the number of hours plus flat fee and you get your answer

The area of the triangle is approximately 31.3049 square inches.

The area of a triangle can be found using the formula: A = (1/2)bh, where b is the length of the base of the triangle, and h is the height (or perpendicular distance from the base to the opposite vertex).

However, in this case, we don't have the height. Instead, we can use

Heron's formula, which only requires the lengths of the three sides of the triangle:

A = √[s(s-a)(s-b)(s-c)],

where a, b, and c are the lengths of the sides of the triangle, and s is the semiperimeter (half the perimeter):  s = (a + b + c)/2.

Using the given values, we have:

s = (7 + 9 + 12)/2 = 14

A = √[14(14-7)(14-9)(14-12)]

A = √[14(7)(5)(2)]

A = √(980)

TT = (∂O/∂u) x (∂O/∂v)
  = (2, 0, 8) x (0, 0, 1)
  = (-8, 0, 0)

To find n(u,v), we normalize TT:

The original number was 17 to which when Angad adds 20, then doubles it and gets an answer of 53.

To solve this problem, we need to work backwards from the final answer. If Angad added 20 to the original number, we can subtract 20 from 53 to get 33. This means that after Angad doubled the number, he had 33.

To find the original number, we need to undo the doubling process. If Angad had 33 after doubling the number, we can divide 33 by 2 to get the original number.

33 divided by 2 equals 16.5. However, we know that the original number must be a whole number since we cannot add 20 to a decimal. Therefore, we can round up to the nearest whole number to get 17.

So, the original number was 17.

In summary, to find the original number, we worked backwards from the final answer and undid the steps that Angad took. We subtracted 20 to undo the addition, then divided by 2 to undo the doubling. We rounded up to the nearest whole number since the original number must be a whole number.
