What is the approximate radius of a 112 48 cd nucleus?

radius of a nucleus is 5.784× meters

Step-by-step explanation:

Since radius of a nucleus is measured by the formula

R =

Where is the average radius of a nucleus. This radius varies with the size of nucleons.

In this formula A = number of nucleons = (Number of protons + neutrons)

For element Cd number of nucleons = 112

and = 1.2×

Now we put these values in the given formula

R =

  =

  = 5.784× meters

Therefore, radius of a nucleus is 5.784× meters

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15
