Since the question is asking how many pencils the teacher will have to give out, we can automatically ignore the 46 erasers from the problem because it is not relevant. The information was most likely put there to confuse you.

Each student is getting 28 pencils, so if we multiply the number of students by 28 pencils, we will find how many pencils the teacher will need to give out.

There are 42 children in the classroom, so multiply 42 by 28.

42 * 28 = 1,176

The teacher will have to give out <u>1,176 pencils</u> to her 42 children in the classroom.

What is the slope and the y-intercept of the line 12x+2y=-60

aivan3 [116]

Answer:

The slope is -6 and the y intercept is (0, -30)

Step-by-step explanation:

Rearrange the equation into y = mx + b form, where m is the slope and b is the y intercept:

12x + 2y = -60

Subtract 12x from both sides:

2y = -12x - 60

Divide each side by 2:

y = -6x - 30

So, the equation in slope intercept form is y = -6x - 30

The slope is -6 and the y intercept is (0, -30)

In the example we modeled the world population in the second half of the 20th century by the equation P(t) = 2560e^(0.017185t).

Lyrx [107]

Answer: There are 6045 millions world population during the period of 1950 to 2000.

Step-by-step explanation:

Since we have given that

The world population in the second half of the 20 the century by the equation:

$P(t)=2560e^{0.017185t}$

We need to find the average world population during the period of 1950 to 2000.

So, there are 50 years between 1950 to 2000.

So, t = 50 years.

Therefore, the average population would be

$P(50)=2560e^{0.017185\times 50}\\\\P(50)=6045.15\\\\P(50)\approx 6045\ millions$

Hence, there are 6045 millions world population during the period of 1950 to 2000.
