Derrick's Doggie Day Care charges a $12 registration fee plus $5 per hour for pet sitting. Pauline's Pooch Park charges $3 per hour plus an $18 registration fee. Which inequality below can be used to find the number of hours, h, for which the cost of Derrick's Doggie Day Care is at most the cost of Pauline's Pooch Park?

the number of hours is >4

Step-by-step explanation:

given data

Derrick's Doggie

$12 registration fee plus $5 per hour for pet sitting.

the total charges for Derrick's Doggie  will be

y=12+5h1

Pauline's Pooch Park charges $3 per hour plus an $18 registration fee.

the total charges for Derrick's Doggie  will be

y=18+3h2

equating 1 and 2 we can solve for h which is the number of hours

12+5h=>18+3h

12-18=3h-5h

-8=-2h

h=8/2

h=>4

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.
