The answer is D.

If he pays for the full haircut, that’s 100% which is equal to 1

15% is basically 0.15

1 + .15 = 1.15

Both scale off of x, the total of the haircut, so you’d multiply it by x making it 1.15x

Apologies if that doesn’t make sense but it is D

(01.05 LC)Which fraction is equivalent to negative 3 over 7? negative 7 over 3 3 over negative 7 3 over 7 7 over 3

Kitty [74]

Answer:

Second option

Step-by-step explanation:

Given the following question:

$-\frac{3}{7}$

In order to find the answer, we will apply the fraction rule.

$\frac{a}{-b} =-\frac{a}{b}$
$\frac{3}{-7} =-\frac{3}{7}$
$=\frac{3}{-7}$

Not the third or fourth option because negatives do not equal a positive. It's also not option A because....

$-\frac{7}{3} =7\div3=-2\frac{1}{2}$

Your answer is indeed the second option.

Hope this helps.

Emily practices piano for 2/3 of an hour on Monday and 1/2 hour on Wednesdays. How many hours does Emily spend practicing piano

Sergeu [11.5K]

Answer:

50 minutes

Step-by-step explanation:

Given:

$\bullet \ \ \text{Monday:} \ \dfrac{2}{3} \times \text{Hour}\\\\\bullet \ \text{Wednesday:} \ \dfrac{1}{2} \times \text{Hour}$

Since Emily only practiced on Monday and Wednesday, the sum of time on both days is the time Emily practiced on the piano for a week.

$\implies \text{Monday + Wednesday = Total time practiced on piano for a week}$

<u>Substitute the times in the equation</u>

$\implies (\dfrac{2}{3} \times \text{Hour}) + (\dfrac{1}{2} \times \text{Hour}) = \text{Total time practiced on piano for a week}$

<u>Simplify the equation</u>

$\implies (\dfrac{2}{3} \times 60 \ \text{minutes}) + (\dfrac{1}{2} \times 60 \ \text{minutes}) = \text{Total time practiced on piano for a week}$

$\implies (20 \ \text{minutes}) + (30 \ \text{minutes}) = \text{Total time practiced on piano for a week}$

$\implies \boxed{50 \ \text{minutes} = \text{Total time practiced on piano for a week}}$
