Two friends, Alejandro and Mia, agreed to split the check at a restaurant. Alejandro ordered $12 worth of food and Mia ordered $

kvasek [131]

Cost of Alejandro's food = $12

Tip paid by Alejandro = 20% of his bill = 20% of 12 = 2.4

Cost of Mia's food = $18

Tip paid by Mia = 15% of his bill = 15% of 18 = 2.7

Total Tip Paid = 2.4+2.7 = 5.1

Total Check Amount = 12 + 18 = 30

Total tip paid by Alejandro and Mia is r% of the total check amount.

So, we need to determine what % of 30 is equal to 5.1%

⇒ r% × 30 = 5.1

⇒ r% = 5.1 / 30

⇒ r% = 17%

Hence, r is 17%

A bag contains 8 black marbles and 20 yellow marbles. You reach into the bag and pull out a black marble. Then you reach into th

sveticcg [70]

You have a bag containing 8 + 20 = 28 marbles.

After you pull a black marble you have 28 - 1 = 27 remaining marbles.

There are 20 yellow marbles in the bag.

The probability of pulling a yellow marble is now

$\frac{20}{27} which \: is \: approximately \: equal \: to \\ 74.07\%$

1) Find an equation of the line that passes through thr pair of points (-5,-9) and (2,-7).

Yuki888 [10]

1: Assuming this line is linear, the first thing to do is find the slope.
The slope formula is $m=\frac{ y_{2} - y_{1} }{ x_{2} - x_{1} }$ , so in this case, it is $m=\frac{ (-7) - (-9) }{ 2 - (-5) }$ , which comes to $\frac{2}{7}$ . Then, use your slope and one of the points given to write the point-slope formula of the linear equation, and then written in standard form:
y= $\frac{2}{7}$ x- $\frac{53}{7}$ .

2. Use the same process as in question 1 to find:
y=-7x+11
