May someone help me out with these problems? Please explain

Well you have to solve each problem first to make them the same. Let's do decimals.

a) The square root of 58 is 7.61577310586. Let's round that to 7.62. You can solve this with a calculator.

b) Simply -32.0, since it is a whole negative number.

c) I think there's a typo, 'C' is the second 'b)', which is 49/7. 49 divided by 7 is seven, hence the decimal would be 7.0

d) 2.65 repeated, already a decimal, does not need changed.

e) The square root of 6 is 2.44948974278. Let's round that to 2.45.

f) is just 0. no decimal, just 0.

Now that you have these as the same form of number, you have to put them into one of these categories. The categories can be found below.

Any square root number is irrational. Any never ending number is irrational, like pi, but there are none of those in this situation. So a, and e are all irrational.

Any repeated number, in this case, 2.65 repeated, is a rational number, as is any decimal or fraction, but there are none of these, so d is rational.

-32 is and integer, because it is a negative whole number, so b is an integer.

Whole numbers are any numbers 0+. So f is the only answer that is a whole number.

Natural numbers are any numbers 1+. So c or the second b is a natural number.

Hope this helps :)

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
