Out of the 860 students, 43 were out sick. what percent of the student population is ill?

To express a number as a percentage, you need to write it as a ratio with denominator 100.

We know that ratios have different forms they can be written into, for example, all the following are equivalent:

So, since 43 students out of 860 are sick, the ratio of sick students is

and we want to express this as a ratio with denominator 100, so we have

So, if we solve for x, we have

So, 5% of students is sick.

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.

48 / 6 = x

in this case, x will equal the amount of money in each card!

x therefore will be 8.

trent had $8 in each birthday card.
