The percentage increase in the area of a rectangle is 44% if each of its sides is increased by 20%.

<h3>What is a rectangle?</h3>

It is defined as two-dimensional geometry in which the angle between the adjacent sides is 90 degrees. It is a type of quadrilateral.

It is defined as the area occupied by the rectangle in two-dimensional planner geometry.

The area of a rectangle can be calculated using the following formula:

Rectangle area = length x width

New length = (120x/100) m

New breadth = (120y/100) m

New area = (6x/5 × 6y/5) m²

The difference between the original area = xy

new area 36xy/25

Percentage increase = (11xy/25 1/xy x 100)

= 44%

Thus, the percentage increase in the area of a rectangle is 44% if each of its sides is increased by 20%.

The average fraction of the students in the two classes is 17/20.

<h3>What is a fraction?</h3>

A fraction is a ratio of two integers called the numerator and denominator.

Analysis:

sum of the fraction of both students in the two classes = 4/5 + 9/10 =

LCM of the denominators which are 5 and 10 is 10

so the sum of both fractions = 8/10 + 9/10 = 17/10

The average = 17/10 /2 = 17/10 x 2 = 17/20

In conclusion, the average of the fraction of students on both classes is 17/20.

Tracy works at the Pizza Place. She earns $4.50 an hour plus tips. Last week, she earned a total

sweet [91]

Answer:

She work <u>23 hours</u>.

Step-by-step explanation:

Given:

Tracy works at the Pizza Place. She earns $4.50 an hour plus tips.

Last week, she earned a total of $156.00, of which $52.50 was tips.

Now, to find the number of hours she work.

Total salary = $156.00

Amount of tips = $52.50.

So, first we deduct the amount of tips from the total salary:

$\$156.00-\$52.50\\=\$103.50.$

<em>Thus, the remaining salary = $103.50.</em>

As, given salary she earns an hour = $4.50.

And then, to get the number of hours she work last week by dividing $103.50 the remaining salary by $4.50:

$103.50\div 4.50$

$=23\ hours.$

Therefore, she work 23 hours.

The tallest building in Africa is the Carlton Centre in Johannesburg, South Africa. What is the distance from the top of this 73

Contact [7]

Answer:

b = 33 miles

Step-by-step explanation:

The illustration forms a right angled triangle. The opposite side of the triangle is where we are looking for . The adjacent side is the radius 4000 miles.

5280 ft = 1 mile

735 ft = ? miles

cross multiply

735/5280

miles = 0.13920454545 miles

The hypotenuse side is the height of the building + 4000 miles = 0.140 + 4000 = 4000.14 miles

using Pythagoras theorem

c² = a² + b²

c = 4000.14

a = 4000

4000.14² = 4000² + b²

b² = 4000.14² - 4000²

b² = 16001120.0196 - 16000000

b² = 1120.0196

b = √1120.0196

b = 33.4666938911

b = 33 miles
