Answers

Answer 1

Answer:

Time is the duration during which any activity or work is performed. Jeanette's sister started 4 hours before the 9:00 pm which is 5:00 pm.

Given-

Jeanette's sister charges $5.50 per hour before 9:00 pm.

Jeanette's sister charges $8 per hour after 9:00 pm.

She finished babysitting at 11:00 pm

She earned total money $38.

What is time?

Time is the duration during which any activity or work is performed.

Total hour she worked after the 9:00 pm,

$=11-9=2$

Thus she worked total 2 hours after the 9:00 pm. She charges charges $8 per hour after 9:00 pm.Hence money earned by her in 2 hours after 9:00 pm ,

$=2*8=16$

Thus money earned by her in 2 hours after 9:00 pm is $16. The money earned by her before the 9:00 pm is addition of money earned by her before 9:00 pm and after 9:00 pm. Let money earned by her before 9:00 pm is $x. Thus,

$x+16=38$

$x=38-16$

$x=22$

Thus the money earned by her before 9:00 pm is $22.

She charges $5.50 per hour before 9:00 pm. Hence the $22 charged by her in hours,

$=(22)/(5.50) =4$

Therefore, hence Jeanette's sister started 4 hours before the 9:00 pm which is 5:00 pm.

Answer 2

Answer:

Hey there! :D Jeanette's sister started at 5:00 PM. To get that answer, here's what I did: From 5-9 PM, she earned $22. That's because 5.50 x 4 = 22, then from 10-11, she charged $8 which is 8 x 2 = 16 + 22 = $38. Again, she started at 5 PM.

Hope it Helps and makes sense! :D

8) not equal, not equal, equal
9) 1/8 of a pound is in each portion
10) $3.75

I hope this helps you. With number 8, all i did was simplify the fractions and see if the can be equal to the first fraction in the whole question and determined my answer by that. For number 9, i divided 1/2 of a pound by 2 and got 1/4 of a pound, and then divided that by 2, and i got the answer of 1/8 of a pound. When it come to number 10, i multiplied $0.50 by 7 and got $3.50, and since the last part was half a foot i knew it would cost $0.25 instead of $0.50, so i just added that to the answer and got the end result of $3.75.
