Answer:

Trent is wrong.

This is because:

π = 25.12/2 × 5

π = 25.12/8

Step-by-step explanation:

A pizza is circular is shape, the formula for the circumference of a circle is :

C = 2× π × r

Making π the subject of the formula

π = C/2r

The circumference of the pizza is 25.12 inches. The radius of the pizza is 4 inches,

Hence:

π = 25.12 inches/ 2 × 4 inches

π = 25.12/8

From the calculation above, Trent is wrong.

The mass of a proton is approximately 1.67 x 10−24, and the mass of an electron is approximately 9.11 x 10−28. Find the approxim
nataly862011 [7]

Answer:

≈ 1833

Step-by-step explanation:

To find ratio of proton mass to electron mass, we have to divide.

The numbers are given in <em>scientific notation</em>.

Let a number be  a*10^b and another be  c*10^d, when we divide, we will follow the rule shown below:

\frac{a*10^b}{c*10^d}=(\frac{a}{c}*10^{b-d})

Now, we use the information given to find the ratio:

\frac{1.67*10^{-24}}{9.11*10^{-28}}\\=(\frac{1.67}{9.11}*10^{-24--28})\\=0.1833*10^4

This means we can find the number by taking 4 decimal places to the right, so that would becomes:

0.1833*10^4=1833

The approximate ratio is 1833 [mass of proton is around 1833 times heavier than mass of electron]
