PLEASE HELP ME ANSWER THIS PLEASE

I believe, by process of elimination, it is "Kara's fee for the second child is $5"

Step-by-step explanation:

It can't be the second option because if her hourly rate for 2 kids was 14, then on hour 2 the total would be $28.

It can't be the third option because Jill's pattern is $11 dollars an hour, and Kara's is adding $9. So, by hour 4, Jill would make $44 and Kara would make $41.

Lastly, it can't be the 4th option because 11-9=2. 2 does not equal 3.

b. 24 mm

step-by-step explanation:

use the pythagorean theorem.

a^2 + b^2 = c^2

a^2 + 7^2 = 25^2

a^2 + 49 = 625

a^2 = 576

a = 24

answer: b. 24 mm

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)

have a good day!
