Here’s what you can do to make this very simple. Consider that the “missing” space between the rectangles isn’t there. Then, find the area:

10 x 9 = 90 mm

Now, find the area of the “missing” part.

5 x 2 = 10 mm

Finally, you deduct the missing part from the complete rectangle!

90 - 10 = 80 mm

The area of this whole thing is 80 mm!

Answer:

A_{total} = 80\ mm^2

Step-by-step explanation:

<u>Step 1:  Determine the area of the bottom rectangle</u>

A = l * w

A = (9\ mm) * (10\ mm - 5\ mm)

A = 9\ mm * 5\ mm

A = 45\ mm^2

<u>Step 2:  Determine the area of the top rectangle</u>

A = l * w

A = (9\ mm - 2\ mm) * (5\ mm)

A = 7\ mm * 5\ mm

A = 35\ mm^2

<u>Step 3:  Determine the total area</u>

A_{total} = 45\ mm^2 + 35\ mm^2

A_{total} = 80\ mm^2

Answer: A_{total} = 80\ mm^2

There are x number of students at helms. If the number of students increases by 7.8% each year, how many students will be there
vodomira [7]

There will be 1.078x students next year and equation is number of students in next year = x + 7.8% of x

<h3><u>Solution:</u></h3>

Given, There are "x" number of students at helms.  

The number of students increases by 7.8% each year which means if there "x" number of students in present year, then the number of students in next year will be x + 7.8% of x

Number of students in next year = number of students in present year + increased number of students.

\begin{array}{l}{\text { Number of students in next year }=x+7.8 \% \text { of } x} \\\\ {\text { Number of students in next year }=x\left(1+\frac{7.8}{100}\right)} \\\\ {\text { Number of students in next year }=x(1+0.078)=1.078 x}\end{array}

Thus there will be 1.078x students in next year

oee [108]

Step-by-step explanation:

if each the bonus is shared equally each will get 420

if 40% is shared by managers each manager will get 560

if 7 sales persons share 60% each will get 360

therefore Peter salesperson will get 360
