For every A earned, Max's parents allowed Max to stay up 15 minutes later. Max's normal bedtime was 8:30. a. For Max's bedtime to change to 9:00 how many A's must he earn?
b. Max would like to have his bedtime to be one hour later. How many A's would that require?
c. For every C, Max's parents made his bedtime 1/2 hour earlier! Max earned 2 A's and 2 C's. what time must he go to bed?

answer A, B and C thanks

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it

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.
