A twelve pack of juice costs $3.90. An eighteen pack costs $5.49. Which is the better buy?

Answers

Answer 1

Answer: The better buy is the one that costs the least per pack of juice. If there are twelve packs of juice in the $3.90 package, then you would divide 3.90 by 12 to see how much each pack costs. If there are eighteen packs of juice in the $5.49 package, then you would divide 5.49 by eighteen.
After I did the math, I found out each pack in the 12-pack costs 33 cents, and each pack in the 18-pack costs 31 cents. So the 18-pack would be the better buy.

Answer 2

Answer: the answer is the first one, because if you divide 12 by 3.90, and 18 by 3.28, you get $3.08 for the first one and $3.28 for the second one

What is the absolute value equation for this graphy = -|x + 2| + 4
y = -|x + 2| - 4
y = -|x - 2] + 4
y = -|x - 2| - 4

Answers

Answer:

y = -|x - 2| + 4

Step-by-step explanation:

The parent function of the absolute value function is y = |x|. There is a negative reflection in the x-axis, a horizontal translation of 2 units right, and a vertical translation of 4 units up.

There were 900 students enrolled in a high school in 2009 and 1,500 students enrolled in the same high school in 2012. The student enrollment of the high school, P, has increased at a constant rate each year, t, since 2009. A) Write the given enrollment numbers as a pair of points in the form (t, P).
B) Find the slope of the line passing through the pair of points from part A and explain the information the slope gives about the situation.
C) Write an equation that relates the high school's student enrollment, P, to the number of years since 2009, t.
D) Predict the high school's enrollment in 2017.

Answers

Answer: A) $(0,900)\ and\ (3,1500)$

B) Slope=200, It means enrollment of 200 students increases each year.

C) $P=200t+900$

D) 2500 students.

Step-by-step explanation:

Given: The student enrollment of the high school, P, has increased at a constant rate each year, t, since 2009.

At 2009, t=0 and at 2012, t=3 [Since 2012-2009=3 years]

A) In points , the given enrollment numbers will be written as:-

$(0,900)\ and\ (3,1500)$

B) The slope of the line passing through $(0,900)\ and\ (3,1500)$ is given by:-

$m=(y_2-y_1)/(x_2-x_1)=(1500-900)/(3-0)=(600)/(3)=200$

It means enrollment of 200 students increases each year.

C) The linear equation with slope= 200 and and the initial number of students (900) is given by

$P=200t+900$

D) At 2017, t=8 [Since 2017-2009=8]

Then $P=200(8)+900=1600+900=2500$

The high school's enrollment in 2017 = 2500 students.

HELP WITH THIS QUESTION PLEASE AND THANK YOUU!!!

Answers

Answer:

s = 35pi units

We can either leave it with pi in the answer or approximate

s= 109.9557429 units

Step-by-step explanation:

Arc length is found by

s = r * theta where r is the radius and theta is given in radians

Changing the angle from 150 degrees to radians by multiplying by pi/180

150 *pi/180 = 5/6 pi

Now we can use the formula

s = 42 * 5/6 pi

s = 35pi

We can either leave it with pi in the answer or approximate

s= 109.9557429 units
