What is defined as the rectangle?A rectangle is a closed two-dimensional shape with four sides, four corners, and four right angles (90°).
A rectangle's opposite sides are equal as well as parallel. Because a rectangle is a 2-D shape, it has two dimensions: length and width. The length of the rectangle is the longer side, and the width is indeed the shorter side.Now, as per the given question;
The area of the rectangular floor is given as two hundred thirty-nine and one-fourth square feet.
Thus,
A = 239.25 feet
The width is fourteen and one-half feet.
Thus,
W = 14.5 feet
The formula for area is;
A = L×B (L is the length)
Put the values;
239.25 = L×14.5
L = 239.25/14.5
L = 16.5 feet
The rectangular perimeter is;
P = 2(L + B)
P = 2(16.5 + 14.5)
P = 62 feet
Therefore, the perimeter of the rectangle floor is found to be 62 feet.

Ordered: 130 mg. Available: 1 gr/tablet. How many tablets should be given? ________
Answers
Answer:
2
Step-by-step explanation:
1gr=100mg
130-100=30
No tablets should be given since the ordered quantity of 130 mg is less than the available quantity per tablet of 1 g.
How many tablets should be given?We have the following data:
Ordered amount: 130 mg
Available amount per tablet: 1 g
To decide the number of tablets to be given, we have to be make sure the units are steady. Let's change over the ordered amount to grams:
130 mg = 130/1000 g = 0.13 g
Presently, we are able calculate the number of tablets:
Number of tablets = Ordered amount / Available amount per tablet
Number of tablets = 0.13 g / 1 g = 0.13 tablets
Since we cannot administer a fraction of a tablet, we round the result to the closest whole number. In this case, 0.13 is less than 0.5, so we round down:
Number of tablets to be given = tablets
Hence, no tablets ought to be given since the ordered amount of 130 mg is less than the available amount per tablet of 1 g.

Charles, age 45, would like to determine how much life insurance to purchase using the human life value approach. He assumes his average annual earnings will remain at $40,000. Of this amount, $20,912 is available annually for the support of his family. Charles will generate this income for 24 more years and he believes that 5.37 percent is the appropriate interest (discount) rate. What is Charles' human life value? (Round your answer to 2 decimal places)
Answers
Using it's formula, it is found that Charles' human life value is of $26,951.39.
What is the human life value formula?The human life value formula(HLV) is given by the following multiplication:
HLV = Annual Expenses x Number of Years x Interest Rate.
For this problem, we have that:
$20,912 is available annually for the support of his family, hence the annual expenses are of $20,912.Charles will generate this income for 24 more years, hence the number of years is of 24.As stated in the problem, the interest rate is of 5.37%, hence, as a decimal, is of 0.0537.Hence, applying the formula, we have that Charles' human life value is found as follows:
HLV = 20912 x 24 x 0.0537
HLV = $26,951.39.
Charles' human life value is of $26,951.39.

A mathematical expression is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Let x be the amount invested at 9% rate.
And (28000−x) be the amount invested at 2% rate.
The total annual income is $1435
Let us find the amount invested at 9% rate:
x9%+2%(28000−x)=1435
9%+2%(28000−x)=1435
0.09x+0.02(28000−x)=1435
0.09x+560−0.02x=1435
0.09x−0.02x=1435−560

Let us find the investment amount at 2% rate:

Brody's age is 3 years less than twice Trinity's age? The sum of their ages is 30.
Answers
Answer: Brody's Age is 19 and Trinity's age is 11
Step-by-step explanation:
x = Trinity's age
2x-3= Brody's age
The sum of the ages is 30, so
x + (2x-3) = 30
3x - 3 = 30
add 3 to both sides 30 turns into 33 so,
3x = 33
divide by 3 both sides
x = 11 which is trinity's age and plug x into 2x - 3 which is 19 so that's Brody's age.
