Dan learned the mass of an electron is about 9.1×10⁻³¹ while the mass of a proton is about 1.7×10⁻²⁷. He thinks electrons have a

greater mass than protons because 9.1 is greater than 1.7; Do you agree with him? How can you use scientific notation to compare the mass of an electron and a proton? Explain your thinking.

Answer:

\sf adjacent  = 4.5 \ ft

Given:

  • opposite side: 13 ft
  • adjacent unknown
  • angle of 71°

using tan rule:

\sf tan(x) = \dfrac{opposite}{adjacent}

\hookrightarrow \sf tan(71) = \dfrac{13}{adjacent}

\hookrightarrow  \sf adjacent  = \dfrac{13}{tan(71) }

\hookrightarrow  \sf adjacent  = 4.5

Which ratio is different?<br><br> 3 : 7<br><br><br> 3 to 7<br><br><br> 3/7<br><br> 7 to 3
Masteriza [31]

Answer:

7 to 3 is this answer

Step-by-step explanation:

if you noticed, with all the other ones they all have 3 : 7 in it. So by the process of elimination it's 7 to 3 that is different. I'll tell you why,

3 : 7, that is the ratio we have as an example. That's why it isn't the different one.

3 to 7, you say 3 : 7 as 3 to 7 to it still has the same ratio

3/7, this is how to type the fraction version of the ratio so it makes sense that it is the same one as 3 : 7.

7 to 3, if you haven't noticed yet, all of them has 3 : 7 as a counterpart. They are all the same but this one, this is 7 : 3 or 7 to 3. So with logic, this is the different ratio.
