What is rectangle ?
A rectangle is a quadrilateral with four right angles in the Euclidean plane. It can alternatively be described as a parallelogram with a right angle or an equiangular quadrilateral, where equiangular denotes that all of its angles are equal. A square is a rectangle with four equally long sides.
An equiangular quadrilateral is another name for a rectangle. The reason for this is that a rectangle is a quadrilateral form (4-sided shape) with parallel sides that are equal to one another and four corners with 90o angles. A rectangle can also be referred to as an equiangular quadrilateral because all of the angles are 90 degrees.
Rectangle area = width * height
44.52 / 21
= 2.12 feet

if p1, p2 and p3 are probabilities of surviving for years 1, 2 and 3 respectively, what is the cumulative probability of surviving for 3 years?
If p1, p2 and p3 are probabilities of surviving for years 1, 2 and 3 respectively, then the cumulative probability of surviving for 3 years is p1 + p2 + p3
The probability of surviving for 1 year = p1
The probability of surviving for 2 year = p2
The probability of surviving for 3 year = p3
The probability is the ratio of the number of favorable outcomes to the total number of outcomes.
The cumulative probability is defined as the probability distribution of random variables
The cumulative probability = p1 + p2 + p3
Therefore, the cumulative probability of surviving for 3 years is p1 + p2 + p3

How to determine the length of a line segment
In this problem we find the case of a geometric system formed by a line segment PR with a point Q on the line between P and R. Thus, a line segment PQ is inside the line segment described above.
According to the statement, the lengths of the line segments PR and QR are known and the length of line segment PQ can be known by Euclidean geometry and algebra:

On January 1, a nasty species of algae is mistakenly introduced into Lake Skinner. It grows in such a way that it doubles every day. If it continues to grow like this, the lake will be totally covered and the fish in the lake will suffocate. At the rate it is growing, this will happen on January 30.
1). When will Lake Skinner be covered halfway?
2). On January 26, you convince your friend that the lake will be completely covered soon. Your friend laughs. Why is your friend skeptical?
3). One January 29 a cleanup crew arrives and is able to remove most of the algae. When they are done on February 1, only 1 % of the surface is covered. How well does this solve the problem in Lake Skinner?
Answer:
1). If the algae doubles every day, it will take 15 days for it to cover half the lake. This means it would happen on January 15.
2). Your friend may be skeptical because they may not believe that the algae can grow so quickly and cover the entire lake in just 30 days. Alternatively, they may not believe that you have accurate information about the situation.
3). Removing most of the algae on January 29 would significantly reduce the amount of algae in the lake and would likely help prevent the lake from becoming completely covered. However, if 1% of the surface is still covered with algae on February 1, it is possible that the problem has not been fully solved and the algae could continue to grow and potentially become a problem again in the future. It would be best to continue monitoring the lake and taking action to prevent the algae from growing.

At first it is important to know about equation
Equation shows the equality between two algebraic expressions by connecting the two algerbraic expressions by an equal to sign.
A one degree equation is known as linear equation.
A linear equation needs to be solved here
Let the number of months for Belvedere to weigh the same as Thor be x months
Thor weighs 192 pounds and plans on losing 2.1 pounds each month.
Weight of Thor after x months = 192 - 2.1x
Belvedere weighs 211 pounds and plans on losing 7.5 pounds per month.
Weight of Belvedere after x months = 211 - 7,5x
By the problem,
The linear equation is
192 - 2.1x = 211 - 7.5x
7.5x - 2.1x = 211 - 192

Part A Fill in the blank question. A model car is for sale online. Beginning on day one, the owner discounts the price by 5% each day until it sells. On the third day the car sells. If the original price of the model car was $40, how much did the car sell for to the nearest cent? $ Part B Fill in the blank question. What percent discount does this represent from the original price? Round to the nearest whole percent.
Part A) If the original price of the model car was $40, and it was sold on the third day, with a daily discount of 5%, the sales amount is $34.30.
Part B) The percentage discount from the original price is 14%.
Calculating the percentage discount:The percentage discount is the total discount divided by the original price multiplied by 100.
In this instance, we compute the total discount as $5.70, then express this value as a numerator with $40 as the denominator. The quotient is multiplied by 100.
Original price of the model car = $40
Daily discount = 5%
The date the car sells = the third day
The sales price on the third day = $34.30 ($40 x 95% x 95% x 95%)
Total discounts = $5.70 ($40 - $34.30)
Percentage discount for three days =14.25% ($5.70/$40 x 100)
