6. If element Q has 11 protons, its atomic<br> is 11.
Vladimir79 [104]

Answer: If element Q has 11 protons, its atomic  <u>number</u> is 11.

Step-by-step explanation:

The atomic number of a chemical element is the total number of protons that each atom of that element has.

In other words: it indicates the amount of protons that is present in the nucleus of an atom.

In this sense, the periodic table of the elements arranges the chemical elements in the form of a table, ordered by their atomic number (number of protons), by their configuration of electrons and their chemical properties.

I’m having troubles with this one.
nikklg [1K]

Answer:

239 degrees.

Arc is circumference so length = r * 4.17133691221

Step-by-step explanation:

We eliminate RSQ in degrees = 90 + 31 = 121

So that;

RPQ = 360 -121 = 239 degrees

2pi radius (239/360) = r6.28318530718 (0.66388888888)

= r * 4.17133691221

-3x/5 divided by 4/5<br><br> Please explain how to solve this.
zloy xaker [14]
You need to keep -3x/5, change the division sign to multiplication and flip 4/5 so it becomes 5/4. When you did that, -3x/5 times 5/4 is equal to -15x/20. Lastly, you simplify it so the answer is -3x/4
