Alexander is drawing a map of the Federal Triangle in Washington, D.C. The actual Federal Triangle has a base of 300030003000 feet and height of 120012001200 feet. Alexander needs his drawing to fit on his paper, so he decides to make the base of his triangle 101010 inches.
1. What scale is Alexander using?
2. What is the height of Alexander's triangle in inches?
Alexander is utilizing a scale of 1 inch : 300 feet for his map.
The Alexander's triangle has a height of 4 inches in inches.
How to determine the map's scaleWhen comparing the initial dimensions as used by alexander, the scale of the map may be determined.
The scale is 1 inch: 300 feet since he used 10 inches to symbolize 3000 feet, this is gotten by diving both sides by 10
Using the scale factor 1 inch: 300 feet, the height of 1200 feet would be.
300 feet per inch, then ? inch is 1200 feet
? * 300 = 1200 * 1
? = 1200 / 300
? = 4 inches

The dogs rescued this year were 1738.
What is ratio?A ratio is a way to show a relationship or compare two numbers of the same kind. We use ratios to compare things of the same type.
Given that, Last year the animal rescue centre rescued 2520 dogs and cats in the ratio of 3:2. This year, the number of dogs rescued has increased by 15%.
Let the number of dogs and cats be x,
3x+2x = 2520

It takes 8 months for the investment to grow to $6000 if interest was compounded quarterly.
What is compound interest?
The interest charged on a loan as well as deposit is known as compound interest. It is the idea that we use the most frequently on a daily basis. Compound interest is calculated for an amount based on both the principal and cumulative interest. The main distinction between compound as well as simple interest is this.
Given:
Principal amount = $5000
Annual amount interest = 2.6%
Compounded quarterly = 4
Final amount = $7000
Formula:
A = P(1 + r)^4n - 1
A is the quarterly compounded interest.
P would be the principal amount.
r is the quarterly compounded rate of interest.
n is the number of periods.
Solving it:
7000 = 5000 (( 1 + 0.026))^ 4t -1
7/5 = (( 1 + 0.026))^ 4t
7/5 = (1.026)^ 4t -1
ln (7/5) = 4t ln (1.006) - ln 1
t = 7.61 months
t ~ 8months
Hence, it takes 8 months for the investment to grow to $6000 if interest was compounded quarterly.

The population of a town has been decreasing since 1991. The population of the town was 26,700 people in the year 1995. In the year 2003, the population of the town had decreased to 20,300 people.
Find the linear function
P=mt+b that models the town's population, P, as a function of the number of years, t, since 1991.
Find a reasonable domain for the function P
Domain:
Find a reasonable range for the function P
Range:
In what year will the population of the town be 14,700?
Year: ?
The linear function is P=-800(t)+1622700 where P and t are population and years respectively.
Domain of P is (1991, 1992, 1993, ............)
Range of P is (29900, 29100, 298300, .........)
In 2010 there will be 14,700 population
How do you determine a domain's and range's?
How Can I Determine an Equation's Domain and Range? In order to identify the values of the independent variable x and acquire the domain, we simply solve the equation y = f(x). Simply put, x=g(y) will calculate the function's range after we identify g's domain (y).
Given that
In 1995 there will be 26700 population and in 2003 there will be 20300 population
So in above statement we can form 2 linear equations
26700=m(1991)+b
20300=m(2003)+b
by this we can solve for m and b
m = -800
b= 1622700
By this now we can find the year for population of 14700
14700 = -800(t)+1622700

The solution set to the inequality, -1/2m ≥ 7/11, is: m ≤ -14/11 (see attachment for the graph).
How to Graph the Solution Set to an Inequality?Translating the statement given as an inequality, we have:
-1/2m ≥ 7/11
To find the solution, isolate the variable of m to one side of the inequality:
-1/2m ≥ 7/11
Multiply both sides by -2 then change the sign to
-1/2m(-2) ≥ 7/11(-2)
m ≤ -14/11
Therefore, it means the solution is any value of m that is less than or equal to -14/11.

David has a hose that is 27 ft long. He wants to cut it into two pieces is 3 ft more than 2 times the length of the shorter piece
Answer: The shorter piece is 8 ft and the longer piece is 19 ft.
Step-by-step explanation:
Let x be the shorter piece. We will write an equation that represents the original problem to help us solve.
27 ft = x + (2x + 3)
Now, we will solve this equation.
27 ft = x + (2x + 3)
27 ft = 3x + 3
24 ft = 3x
8 ft = x
The shorter piece is 8 ft long.
Then, we will use substitution for the longer piece.
2x + 3
2(8) + 3
19
The longer piece is 19 ft long.

Leo deposit at $7671.12 in an account that earned 2.5% interest compounded weekly for 13 years after 13 years how much had Leo earned an interest
The amount that Leo has earned as interest, given the amount that Leo deposited, and the compounding period, is $2, 945.12
How to find the interest earned?First, find the weekly rate on the account:
= Annual rate / Number of weeks in a year
= 2.5 % / 52
= 0.048 %
The number of periods is:
= Number of years x Weeks per year
= 13 x 52
= 676 weeks
The amount that Leo would have earned after 13 years is:
= Deposit x ( 1 + rate) ^ number of periods
= 7, 671.12 x ( 1 + 0.048%) ⁶⁷⁶
= $10, 616.24
The interest earned is:
= Amount earned - Amount deposited
