Max is saving $10 a month for a summer vacation. If he also has $50 from his grandmother, how many months will Max need to save to have a total of 200? Choose the equation that represents this situation. 1. 50m + 20 = 200
2. 50m - 10 = 200
3. 10m - 50 = 200
4. 10m + 50 = 200

The answer is 4. 10m+50=200

Step-by-step explanation:

4.

Step-by-step explanation:

1. 1 isn't right because he doesn't get $50 a month.

2. See 1.

3. This isn't right because you wouldn't subtract the $50 from 10m.

4. This is right because the total of months plus the 50 will get him to 200.

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
