1 answer:

8 0

I'm not sure this is right, so please don't be mad if I got this completly wrong, but I think this is how you do it. $\frac{ 10q^{6} r^{8} }{ 24r^{5} t^{2} q^{3}}$ next divide $\frac{5}{6} q^{3} r^{3} t^{2}$

Nikitich [7]

Answer:

$\frac{7}{12}$ of the cake

Step-by-step explanation:

add $\frac{1}{8}$ and $\frac{1}{6}$ to see the total amount of cake eaten.

a. find the common denominator: 8 x 3 = 24 and 6 x 4 = 24

b. multiply accordingly to get the correct numerator: $\frac{3}{24}$ + $\frac{4}{24}$

c. add: $\frac{3}{24}$ + $\frac{4}{24}$ = $\frac{7}{24}$

subtract found value from total to find left over cake.

a. 24 - 7 = 14

simplify.

a. $\frac{14}{24}$ = $\frac{7}{12}$

You are left with $\frac{7}{12}$ of the cake.

The grocery store where Ms. Maple works pays her $6.50 per hour. Any time she works more than 40 hours per week, she is paid tim

Charra [1.4K]

Answer:

$289.25

Step-by-step explanation:

First we should find out how much Ms. Maple would make in a week without overtime.

6.5 x 40 = 260

Now, let's figure out how much she makes per hour in overtime.

6.5 x 1.5 = 9.75

Now add up the hours of overtime.

9.75 x 3 = 29.25

Now we add the weekly wage to the overtime

260 + 29.25 = 289.25

For 40 hours of regular time at $6.50/hr and 3 hours of overtime at $9.75/hr, Ms. Maple will make $289.25 for the week.
