Answer:

a = 9.6 b = 11.2

Step-by-step explanation:

10 percent of 8 is .8

8 + (8 x .1) = 8.8

8.8 + .8 = 9.6

She will be paid 9.6 dollars after 1 full year of working, because working for one year is 12 months, and thats 10 percent of 8 twice. You can also put that as 20 percent of 8, aka 1.6

When you do 8+1.6 it equals 9.6

For the second part, that is 24 months, so 10 percent of 8 4 times. .8+.8+.8+.8 = 3.2

8+3.2 = 11.2

She will be paid 11.2 dollars after 2 full years of working.

Your answer isnt wrong, I dont know why your teacher is saying it is.

Three-fifths of the students in a room are girls. One-third of the girls have blond hair. One-half of the boys have brown hair.
yan [13]

Answer:

a. Of all the students, \frac{1}{5} are girls with blond hair.

b. Of all the students, \frac{1}{5} are boys without brown hair.

Step-by-step explanation:

a. You know that \frac{3}{5} of the students are girls (This means that \frac{2}{5} of the studes are boys) and \frac{1}{3} of these girls have blond hair.

Then, \frac{1}{3} of \frac{3}{5} is:

(\frac{3}{5})(\frac{1}{3})=\frac{1}{5}

Therefore, of all the students, \frac{1}{5} are girls with blond hair.

b. You know that \frac{1}{2} of the boys have brown hair.

Then, \frac{1}{2} of \frac{2}{5} is:

(\frac{2}{5})(\frac{1}{2})=\frac{1}{5}

Of all the students, \frac{1}{5} are boys without brown hair.

Amanda [17]

The fabric cost $181.875

Step-by-step explanation:

Blue fabric bought = 3 3/4 yards , change to improper fraction (4*3)+3/4 = 15/4 yards

Red fabric= 12 5/6 yards = 77/6 yards

Purple fabric= 7 2/3 yards= 23/3 yards

Find  total length of fabric bought, 15/4 +77/6 +23/3 =291/12 yards

Cost per yard= $7.50

Total cost will be, 291/12 * 7.50 =$ 181.875
