Michaela spent a total of 12 1/2 hours doing her online learning work this week. If she spent 5 3/4 of those hours working on Monday, how much time did she work the rest of the week?

6 3/4 hours

Step-by-step explanation:

12 1/2 turned into an improper fraction is 25/2. 5 3/4 turned to an improper fraction is 23/4. The common denominator for these fractions is 4. So you have 50/4 -23/4 which is 27/4. The proper fraction form would be 6 3/4.

we know that

applying the law of sines

°

so

∠j=18°

∠k=29°

∠l=180-(18+29)=133°

the answer part a) is

the measure of angle k is  ≈29°

part b)  the measure of angle k could also be

(180-29)=151°

so

∠j=18°

∠k=151°

∠l=180-(18+151)=11°

the answer part b) is

the measure of angle k could also be 151°

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)
