Answer:

There will be 330 7th grade students in this middle school this year.

Step-by-step explanation:

Last year enrollment = 150 students

As the enrollment increased by 120%.

i.e.

Number of Percentage increase = 120% × 150 = 120/100 × 150

                                                       = 1.2 × 150

                                                        = 180

Thus,

Total students this year = No. of Percentage increase + Last year students

                                       = 180+150

                                        = 330 students

Therefore, there will be 330 7th grade students in this middle school this year.

pentagon [3]

Answer:

in units: 18,900

in dollars: $ 41,013

Step-by-step explanation:

The break even point is the sales dollar amount or sales in unit at whichthe operating income of the firm equals to zero:\frac{Fixed\:Cost}{Contribution \:Margin} = Break\: Even\: Point_{units }

Where:

\frac{Contribution \: Margin}{Sales \: Revenue} = Contribution \: Margin \: Ratio

<em><u>Contribution margin:</u></em>

2.17 - 1.27 = 1 dollar per unit

Break even:

$18,900 fixed cost /  $1 per unit = 18,900 units

Then, in sales:

18,900 x $2.17 each = 41.013‬

break even point:

Crazy boy [7]

Artists such as Al Held, Bridget Riley etc are known for their abstract artwork or geometric artwork. Riley is famous for her optical artwork.

This art form is present among many cultures throughout the history both as decorative motifs and as art pieces themselves. Like in Islamic art, this art depicts religious figures. The optical art gives the viewer the impression of movement, hidden images, flashing and vibrating patterns. Basically it gives a disorienting effect.

Besides optical art, other abstract art forms are also famous. These imbibe a strong imagination and a sense of creativity in its viewers. This art form puts different colors, shapes, and textures together to create a finished piece that represents something in particular.

Yes, I appreciate this kind of art form because these forms are genuine and helps us understand the art patterns. Unlike the traditional form, these forms explore the relationships of forms/shapes and colors. Moreover, art always reflects culture. Therefore, abstract art is important because it is reflecting a culture that has been moving since last 2000 years.

Find the slope of the line that passes through the points (0,-11) and (8,-8).
Korolek [52]

To find the slope of a line, we can use the following formula:

\displaystyle \large{m =  \frac{y_2 - y_1}{x_2 - x_1} }

m-term stands for slope or gradient. The formula is useful whenever you want to find a slope of two points.

Let these be the following:

\displaystyle \large{(x_1,y_1) = (0, - 11)} \\  \displaystyle \large{(x_2,y_2) = (8, - 8)}

Substitute the points in formula:

\displaystyle \large{m =  \frac{ - 8 -( - 11)}{ 8 - 0} }

Negative multiply negative always come out as positive.

\displaystyle \large{m =  \frac{ - 8  +  11}{ 8 - 0} } \\  \displaystyle \large{m =  \frac{ 3}{ 8 } } \\

Since m stands for slope, we can say that:

\displaystyle  \large \boxed{ \tt{slope  =  \frac{3}{8} }}
