The surface area of the top open cylinder is 6810.149 sq.cm.

A cylinder is a three-dimensional solid that consists of two congruent surfaces (bases) and one lateral surface.

Surface area of a cylinder = Base area + Lateral area

Base area of a cylinder = 2 × π × r²

Lateral area of a cylinder = (2 × π × r) × h

Therefore, here base area of a cylinder = 2× π × 12²

                                                                  = 5837.27 sq.cm.

And, lateral area of a cylinder = (2 × π × 12) × 2

                                                  = 972.8784 sq.cm.

Therefore, total surface area of a cylinder = 5837.27 + 972.8784

                                                                      = 6810.149 sq.cm.

Answer:4/5

Step-by-step explanation:

80% means 80/100 in fraction. We have to simplify the fraction by 80÷20 and 100÷20 = 4/5

So the answer is 4/5.

Answer:

Step-by-step 80 percent is 80\100 so

For the first one (4\5) 5x20=100 and 4x20=80 which is 80\100

so it should be 4\5

Answer:

  more significant figures than in the answer

  interest is reported to 2 decimal places when working with money

Step-by-step explanation:

Sums of money can involve large numbers of significant figures. A billion dollars, accurate to the penny, has 12 significant digits. Everyday finance may not involve billions of dollars, but measures of world economic activity may involve substantially more.

In general, if you want interest rate calculations accurate to the penny, the number of significant digits in the interest rate used must match or exceed the number of significant digits in the end result of the computation.

A million-dollar loan may have payments in the $10,000 range or higher, requiring 7 or 8 significant digits to express the payment value. Hence its computation should be made using interest rates accurate to 7 or 8 significant figures.

__

Example:

$1,800,000 loan for 15 years at 3.2% interest. The monthly payment is given by ...

  A = P(r/12)/(1 -(1 +r/12)^(-12t)) . . . for principal P at rate r for t years

The payment is expected to be in the $10,000 range, so will have 7 significant figures. If we round the monthly interest rate to 7 decimal places, we get ...

  A = 1.8×10^6(0.0026667)/(1 -(1.0026667^-180)) = 12,604.38

If we round the monthly interest rate to 8 significant figures, we get ...

  A = 1.8×10^6(0.0026666667)/(1 -(1.0026666667^-180)) = 12,604.34

Notice there is a difference in the last digit of the payment value. We should also note here that there was no rounding at any point in the calculation until the final answer.

__

Money amounts are generally rounded to the nearest penny when reported on statements of account. That is, interest amounts are rounded, and the account value is maintained to two decimal places. Because of this, payment-by-payment loan amortization schedules may differ from the calculated values arrived at using formulas such as the one above.

For tax purposes, the amount of tax due may be maintained to a number of decimal digits greater than those that appear on the pay stub. A pay-period tax due of 5.3333, for example, may be charged as 5.33 for two pay periods and 5.34 for the third pay period. The idea is to make the yearly total come out right. Usually, 4 or 5 decimal places will be sufficient for this purpose.

_____

The short answer is ...

  enough significant digits to ensure appropriate accuracy of the computed result

(for penny-accurate computations in the trillion-dollar range, 18 significant digits or more may be required.)

  interest will be reported to 2 decimal places when working with money

Answer: 7/14 = 0.5 or 50%

Step-by-step explanation:

Part A: The theoretical probability of a fair coin landing on heads is 0.5 or 50%.

Part B:

After flipping the coin 14 times, the frequency of each outcome could be as follows:

Heads: 7

Tails: 7

The experimental probability of landing on heads is:

7/14 = 0.5 or 50%

Part C:

Comparing the experimental probability to the theoretical probability, we can see that they are the same. This is expected because the coin is fair, and therefore the probability of it landing on heads or tails should be the same. Thus, the experimental probability of landing on heads is consistent with the theoretical probability of a fair coin landing on heads.

The theoretical probability of a fair coin landing on heads is 1/2. In an experiment where the coin is flipped 14 times, if it lands on heads 7 times and tails 7 times, the experimental probability of landing on heads is 1/2. The experimental probability matches the theoretical probability.

Part A: The theoretical probability of a fair coin landing on heads is 1/2. Since there are only two possible outcomes (heads or tails) and the coin is fair, the probability of landing on either side is equal.

Part B: To determine the experimental probability of landing on heads, you need to flip the coin 14 times and record the frequency of each outcome. Let's say the coin landed on heads 7 times and tails 7 times. The experimental probability of landing on heads is then 7/14 = 1/2.

Part C: Comparing the experimental probability (1/2) to the theoretical probability (1/2), we can see that they are the same. This means that the experimental results align with the expected results based on theoretical probability.

Answer: So when you double the radius, the area goes up by 4 times because 2 squared is 4. The area will always go up by the square of how much the radius goes up. By contrast, the circumference will only double -- from 12.56 to 25.12 because you do not square the radius (or diameter) -- you just multiply it by pi.

Step-by-step explanation:

You want the space diagonal of the given box (a) using the Pythagorean theorem twice, and (b) using the formula.

The length of BD can be found from ...

  BD² = BC² +CD²

  BD² = 18² +4² = 340

  BD = √340 ≈ 18.439

and

  AD² = AB² +BD²

  AD² = 12² + 340 = 484

  AD = √484 = 22

The lengths of the face and space diagonals are ...

No formula is given as part of the problem statement. We can simplify the above calculations to get ...

  AD² = AB² +BD²

  AD² = AB² +BC² +CD²

  AD = √(AB² +BC² +CD²) . . . . . . a reasonable formula

  AD = √(12² +18² +4²) = √(144 +324 +16) = √484

  AD = 22

Answer: 16 different lunch options

Step-by-step explanation:

Since each time, you have two new options so you have to multiply by 2.

Work backwards.

You have white or chocolate milk. You can have Strawberries or Jello with two different options  so in total you have 2 * 2 = 4 different lunches. Then You have green beans or french fries each with 4 different options so 2 * (2*2) = 8 different lunches now. Then you nachos or a fish sandwich each with 8 different options so 2 * (2 * (2*2)) = 16 different lunch options.

In simpler form, you can do, 2 * 2 * 2 * 2 = 16 or \(2^{4}\) = 16, for the four different choices you have.

64 Options.

So there is 7 options which is the nachos, fish sandwich, green beans, fries, strawberries, jello, and 2 different milks. First, add all the foods 1 + 1 + 1 + 1 + 1 + 1 + 2 = 8. Next, multiply the 8 by 8 and it will give you 64.

Thats how you get the answer.

Answer:

Area of five squares = 1289.09 square units

Perimeter =  194.6 units

Step-by-step explanation:

Area of square and perimeter:

   First find the length of each square, then find the area of each square.

To find the area of five squares, add all the area of each square.

Side of square1 = 27 units

\(\sf Side \ of \ square2 = \dfrac{2}{3}*27=2*9 = 18 \ units\\\\Side \ of\ square3= \dfrac{2}{3}*18=2*6=12 \ units\\\\Side \ of \ square4=\dfrac{2}{3}*12=2*4=8 \ units\\\\Side \ of \ square5=\dfrac{2}{3}*8=\dfrac{16}{3}=5.3 \ units\)

Area of square1 = 27*27 = 729 square units

Area of square2 = 18*18 = 324 square units

Area of square3 = 12*12 = 144 square units

Area of square4 = 8*8 = 64 square units

Area of square5 = 5.3*5.3 = 28.09 square units

Area of five squares = 729 + 324 + 144 + 64 +28.09

                                  = 1289.09 square units

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Perimeter of the composite figure = (27 + 27+27+9) + (18+18+6) +(12+12+4) + (8+8+2.7)+ (5.3+5.3+5.3)

                                                         = 90 + 42 + 28 + 18.7 + 15.9

                                                          = 194.6 units

Answer:

B) Square root of 45 and C) Square root of 30, are both irrational numbers, because they aren't perfect squares.

Explanation:

A square root can be defined as, "a factor of a number that, when multiplied by itself, gives the original number."

For example: 8 squared (8^2) is the same as 8 × 8 , which equals 64 , so the square root of 64 is 8. Since 64 is a perfect square, then it makes it a rational number.

Answer:

132 days to 125.4 days percent of change

Step-by-step explanation:

p= N-O/O x 100% where p is the percent change, is the New value and O is

the Old value. We are given the Old value (132) and the New value (125.4) which we can substitute into the formula to calculate the percent change:

p= 125.4-132/132 x 100%

p= -6.6/132 x 100%

p= (-660/132%)
