You and nine friends have decided to take a few days to go camping. you plan a budget of $50 per day for activities. on one of the days you will rent canoes and tubes to explore the river. tube rentals cost $5 and canoes cost $10. each person would need a tube, but canoes hold up to three people. in order to budget for your day on the river, write an equation that shows how many tubes (t) and canoes (c) you would need to accommodate your group, then write an equation that expresses how much the tubes and canoes will cost and remain within the confines of your budget. using the equations, find how many tubes and canoes can be rented.

y=10x+5 because x=3 so 10*3=30 and 30+5=35 which would mean that $35 is the lowest amount you can spend.

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.
