borishaifa [10]

Answer:

Bobby's economic profits for the day is $0.60.

Step-by-step explanation:

Bobby sells 20 glasses of lemonade for $0.20 per cup.

Amount earned = $20\times0.20=4$ dollars

The average total cost is $0.17.

So, difference in selling amount and average = $0.20-0.17=0.03$ dollars

Which set of ordered pairs has the same slope as the given set: (2,9) (1,12)?

Irina-Kira [14]

The slope(m) of the given set is -3.

<h3>What is the slope of a pair of the ordered set?</h3>

The slope(m) of a pair of the given ordered set is the change in the rise over the run. The rise is the y-axis while the run is the x-axis.

Mathematically;

$\mathbf{Slope(m) = \dfrac{\Delta y}{ \Delta x}}$

$\mathbf{Slope(m) = \dfrac{y_2-y_1}{x_2-x_1} }$

Here:

x_1 = 2
y_1 = 9
x_2 = 1
y_2 = 12

$\mathbf{Slope(m) = \dfrac{12-9}{1-2} }$

$\mathbf{Slope(m) = \dfrac{3}{-1} }$

Slope (m) = -3

Therefore, we can conclude that the slope of the given set is -3. From the given option, kindly find out which of the slope is equivalent to -3.

144 students enter a spelling bee, but only 1/6 of the group will make into the semi-final round, and only 2 /3 that group will

DerKrebs [107]

Answer:

16 students

Step-by-step explanation:

144 students enter a spelling bee contest.

Step 1

For the semi final round we are told that only 1/6 of the group will make it into that round.

This is calculated as

1/6 × 144/students = 24 students.

This means that only 24 students would make it into the semi final rounds.

Step 2

We are also told in the question that only 2/3 of THAT group would make it into the final round.

" THAT" group been referred to in the question means the number students that made it to the semi final round

This is calculated as

2/3 of that group( the group that made it to the semi finals)

= 2/3 × 24 students

= 16 students.

Therefore, the number of students that will enter the final round of the spelling bee is 16 students.
