Kayak world charges $10 to rent a spray skirt all day plus $12.50 an hour to rent a kayak. boatland charges $5 to rent a spray skirt all day plus $15 an hour to rent a kayak. write an equation to find h, the number of hours for which the total cost is the same at both rental places. then solve the equation, and state what the cost is when it is the same

Write an equation for each rental place to calculate total cost:

Kayak World = 12.50h + 10

Boat Land = 15h + 5

Now set both equations equal to each other and solve for h:

12.50h + 10 = 15h +5

Subtract 5 from each side:

12.50 + 5 = 15h

Subtract 12.50h from both sides:

5 = 2.50h

Divide both sides by 2.50:

h = 5 / 2.5

h = 2

The cost will be the same for 2 hours.

the answer is a

step-by-step explanation:

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.
