The discount is $2.50, the new price would be $2.50. Unless you factor in sales tax.

satela [25.4K]

Answer:

<h2>20 percent *25 = x</h2><h2 /><h2>( 20:100)*25 = x</h2><h2 /><h2>( 20*25):100 = x</h2><h2 /><h2>500:100 = x</h2>

 

hence , 20 percent of 25 is 5 .

Use the dot plot to answer the question.

Tcecarenko [31]

Answer:

Mean of the data set in the dot plot would be: 3.6

Step-by-step explanation:

As we know that Mean from the dot plot can be obtained by:

adding the numbers and then
divide the resulting sum by the number of addends.

Please check the attached figure where the dot plot is also plotted.

From the dot plot, it is clear that

There are 3 dots at 1.

There are 4 dots at 2.

There are 3 dots at 3.

There are 4 dots at 4.

There are 5 dots at 5.

There are 3 dots at 6.

All we have to do is to add the dots and divide the sum by the number of addend dots.

In other words:

There are 3 dots at 1 ⇒ 1+1+1

There are 4 dots at 2 ⇒ 2+2+2+2

There are 3 dots at 3 ⇒ 3+3+3

There are 4 dots at 4 ⇒ 4+4+4+4

There are 5 dots at 5 ⇒ 5+5+5+5+5

There are 3 dots at 6 ⇒ 6+6+6

As there are total 22 dots.

And the sum of all the dots with respect to their plot number = 79

i.e. 1+1+1+2+2+2+2+3+3+3+4+4+4+4+5+5+5+5+5+6+6+6 = 79

Thus

Mean of the data set in the dot plot = 79/22

= 3.6

Therefore, Mean of the data set in the dot plot would be: 3.6

svetlana [45]

Percentage of people who buy Burgers = 35+45/2 = 80/2 = 40

Total Number of people = 900

So, 900 * 40%

= 900 * 0.40

= 360

In short, Your Answer would be: 360 burgers

Hope this helps!

The isotope cobalt-60 has a nuclear mass of 59.933820 u

Lesechka [4]

Cobalt has an atomic number (Z) of 27, which means the nuclei of all its isotopes have 27 protons. Cobalt 60 has an atomic mass of 60, so it has 60-27 = 33 neutrons.

The mass of 27 isolated protons plus the mass of 33 isolated neutrons would be:

27*(1.007825 u) + 33*(1.008665 u) = 60.497220 u

The actual mass of the nucleus of 60-Co is 59.933820 u.

Mass defect: 60.497220 u - 59.933820 u = 0.563400 u

The mass defect is equal to the binding energy of a nucleus.
using the fact that 1 u = 931.5 MeV/c^2

(0.563400 u)*(931.5 MeV/u) = 524.807 MeV
