Mr. Loureiro arrives at school at 7AM, He starts the day with 9 sharpened pencils. He asks Annel to sharpen pencils. Annel sharpens 11 pencils every minute for 7 minutes. What was the number of pencils sharpened at 7:07

86

Step-by-step explanation:

multiply 11 by seven and then add nine because thats what you had originally.

we multiply because in those seven minutes we're constantly adding more pencils so instead of adding, multiplication is the easiest to do

9+(7x11)

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.

if y=4x then you will substitute 4x in for y in the second equation.

8x + 4x = 18 combine like terms

12x = 18 divide by 12 on both sides

x = 18/12 or 3/2

now replace x in the first equation with 3/2 to get

y = 4 3/2

y = 6

the answer is a

(3/2,6)
