When you convert 3,500,000,000,000 to scientific notation, the exponent

Answer:

$1,540.70

Step-by-step explanation:

1675/335 = 5

3.65 * 335 = 1222.75

Cost of $8.65 per plant, or $2,897.75 for every plant.

12.99 - 8.65 = 4.34

Profit of $4.34 per plant, or $1,540.70 total.

Answer with Step-by-step explanation:

Since 1 mole of sand will contain Avagadro's Number of sand particles (by definition of 1 mole)

Thus we have

1 mole of sand = sand particles

Thus in number of trillion sand particles we have no of trillion sand particles in 12 mole is

Now since it is given that mass of 1 trillion sand particles is 1000 tonnes Thus the mass of trillion sand particles is

Part 2)

Since it is given that volume of 1 sand particle is thus the volume of 1 mole of sand is volume of sand particles

Thus volume of 1 mole is

Now since the Area of united states is

Thus the depth of the sand pile is

Answer:

take home pay = $13,320

Step-by-step explanation:

28% of salary is taxed so take home pay = 72% of salary

= 72% * salary

= 0.72 * $18,500

= $13,320

Answer:

$13,320

Step-by-step explanation:

salary of $18,500

28% of it is deducted in taxes

take home pay = salary x (1 - tax)

= 18500 x (1 - 28%)

= 18500 x 0.72

= 13320

Question:

75is whatpercent of150

Explanation:

PercentageCalculator:75is whatpercentof 150=50

Answer:

50

Answer:

75 is 50 percent of 150.

Step-by-step explanation:

This is a pretty simple concept. First of all for this question, you should have noticed that 75 is half of 150. 50% is equal to 1/2.

There are a couple of methods you could use to solve this problem, if you are using a calculator, a simple way to solve percentage problems is to do 75 divided by 150 (in this case) which gives you 0.50.

If you do not have a calculator and you have to do this on paper, you need to do the classic proportion method. Make two fractions, 75 over 150, and x over 100. (x is what is used to represent an unkown amount.)

We are using over 100 because that is what a percent represents: an amount that is a fraction of 100. now you need to cross multiply. That would be 75 x 100. That equals 7,500. Now cross multiply the other way. That is 150x or represent 150 times x. Now solve the equation 150x = 7,500. To solve this you need to isolate the variable, x by dividing the 150 multiplying the x. That is the coefficient. the attached number next to it. After you do that, you need to divided the other side of the equation by 150. 7,500 divided by 150 equals 50.

After that you will find that the equation shows the value x = 50. You have now found the value of x.

The number of times that both coins come up heads will be 26.25.

What is the expected value?

In parameter estimation, the expected value is an application of the weighted sum. Informally, the expected value is the simple average of a considerable number of individually determined outcomes of a randomly picked variable.

The expected value is given below.

E(x) = np

Where n is the number of samples and p is the probability.

If two coins are flipped. Then the total number of the event is given as,

Total = 2 x 2 = 4 {HH, HT, TH, TT}

Favorable event = 1 {HH}

The probability of getting both same, then we have

P = 1/4

Jenna flips two pennies 105 times. Then the number of times that both coins come up heads will be given as,

E(x) = p × n

E(x) = 1/4 × 105

E(x) = 26.25

The number of times that both coins come up heads will be 26.25.
