The correct answer is B. $ 19.25

Explanation:

To calculate the hourly rate of pay, first, let's calculate the total number of hours Kai worked, and then divide the total earned into the number of hours.

6 hours x 4 days = 24 hours

8 hours x 1 day = 8 hours

24 hours + 8 hours = 32 hours

This shows Kai worked a total of 32 hours. Now to find the hourly rate of pay, follow this procedure:

$616 (total earned) ÷ 32 hours = $19.25 each hour

This means Kai earns $19.25 for each hour of work and therefore the hourly rate of pay is $19.25.

Lisa [10]

Answer:

She lost $2550.

Step-by-step explanation:

She bought 37 meters at $750/m.

37 m * 750/m = $27,750

She paid $27,750

She sold 28 m at $900/m

28 m * $900/m = $25,200

She sold $25,200

$25,200 - $27,750 = -$2550

She lost $2550.

Mars2501 [29]

Step-by-step explanation:

9x^{2} - 9 (a + b)x + 2a^{2} + 5ab + 2b^{2} = 0\\9x^{2} - 3[(3a + 3b)]x + 2a^{2} + 4ab +ab + 2b^{2} = 0\\9x^{2} - 3[(a + 2b) + (2a + b)]x + 2a[a + 2b] + b [a + 2b] = 0\\9x^{2} - 3(a + 2b)x - 3 (2a + b)  + (a + 2b)(2a + b) = 0\\3x [3x - (a + 2b)] -(2a + b)[3x - (a + 2b)]=0\\\:\: [3x - (a + 2b)] - [3x - (2a + b)] = 0\\\\\\\\\circ\:3x - (2a + b) = 0\\\boxed{\underline{x = \frac{2a + b}{3} }}\\\\\\\\\circ\:3x - (2a + b) = 0\\\boxed{\underline{x = \frac{a + 2b}{3} }}

So, the roots are:

<u>1) x = 2a + b/3</u>

<u>2) x = a + 2b/3</u>

The ratio of the number of Miki's stickers to the number of Ken's
Lera25 [3.4K]

Answer:

Miki had 288 stickers and Ken had 252 stickers.

Step-by-step explanation:

This question is solved using a system of equations.

I am going to say that:

Miki has x stickers.

Ken has y stickers.

The ratio of the number of Miki's stickers to the number of Ken's stickers was 8:7.

This means that \frac{x}{y} = \frac{8}{7}, that is: 7x = 8y, or x = \frac{8y}{7}

After Miki gave Ken 18 of her stickers, they had the same number of stickers.

This means that:

x - 18 = y + 18

x - y = 36

Since x = \frac{8y}{7}

\frac{8y}{7} - y = 36

\frac{8y}{7} - \frac{7y}{7} = 36

\frac{y}{7} = 36

y = 36*7 = 252

And

x - y = 36

x = 36 + y = 36 + 252 = 288

Miki had 288 stickers and Ken had 252 stickers.

If you go out to eat with 3 friends and your meal was $72.50, there is 6.75% sales tax
netineya [11]

After the tax and the tip are counted, we conclude that each friend must pay $30.

<h3>How much should each person pay?</h3>

We know that the meal cost is $72.50.

Now, there is a 6.75% sales tax and a 15% tip on the waiter (we assume that the tip is based on the total meal cost, after the tax is applied).

Then the total meal cost is:

C = $72.50*( 1 + 6.75%/100%) = $72.50*(1 + 0.0675) = $77.39

Now we also need to add the tip, which is a 15% of that, so the total cost with the tip included is:

C' = $77.39*(1 + 15%/100%) = $88.998 = $90

(Where we rounded up).

Then, if there are 3 friends, each one must pay:

$90/3 = $30

Each friend must pay $30.
