The actual height of Caleb based on the ratio in the photograph and actual is 48 inches.
What are the ratio and proportion?The ratio is the division of the two numbers.
Proportion is the relation of a variable with another. It could be direct or inverse.
Let's say Allison and Caleb's height in the photograph is A' and C' while in actuality it is A and C.
Since the ratio of height in the photograph will same as the ratio in actual life.
Thereby,
C/A = C'/A'
C/60 = 3.2/4
C = 192/4
C = 48 inches.
Hence "The actual height of Caleb based on the ratio in the photograph and actual is 48 inches".

which statements about doubling in investment are true check all that apply an investment of $5000 will double in six years at an annual compound interest rate of 12% An investment of $1000 will double at an annual compound interest rate of 18% in six years an investment of $350 will double in nine years At a compound interest rate of 8% an investment of $2000 will double at a simple interest rate of 5% in 20 years and investment of $700 will double in 12 years at a simple interest rate of 6%
The following statement are true:
An investment of $5,000 will double in 6 years at an annual compound interest rate of 12%.An investment of $350 will double in 9 years at a compound interest rate of 8%. An investment of $2000 will double at a simple interest rate of 5% in 20 years.What is rule 72?It's an easy way to calculate just how long it's going to take for your money to double. Just take the number 72 and divide it by the interest rate you hope to earn. That number gives you the approximate number of years it will take for your investment to double.
Using the formula
time for doubling money= 72/R
First, An investment of $5,000 will double in 6 years at an annual compound interest rate of 12%.So, 72/12 = 6 years
Thus, It will take 6 years to double the investment. This statement is true.
Second, An investment of $1000 will double at an annual compound interest rate of 18% in 6 years.So, 72/18 = 4 years
Thus, It will take 4 years to double the investment. This statement is not true.
Third, An investment of $350 will double in 9 years at a compound interest rate of 8%.so, 72/8= 9 years.
Thus, It will take 9 years to double the investment. This statement is true.
Fourth, An investment of $2000 will double at a simple interest rate of 5% in 20 years.So, interest = PRT/100
I = (2000 × 0.05 × 20)
I = $2000
Thus, This statement is true.
Fifth, An investment of $700 will double in 12 years at a simple interest rate of 6%Interest = ( 700 × 0.06 × 12 ) = $504
Amount after 12 years
=700 + 504
= $1204.
Thus, This statement is not true.

What is f(g(x) of f(x)=9x+2 and g(x)=x-2 over 9
The value of the composite function f(g(x)) is calculated as f(g(x)) = 65.
What is termed as the composite function?Composite functions is one in which one function is placed within another.
A composite function defines one that is reliant on another. A composite function is defined whenever one function is replaced for another. For example, the composite function constituted by substituting g(x) for x in f is f(g(x)) (x).f(g(x)) is spoken as "f оg(x)."For, the given values in the question;
f(x) = 9x+2 and g(x) = x-2
We have to find the value of f(g(x)) for x = 9.
First estimate the value of g(x) by substituting x = 9 in it.
g(x) = x-2
g(9) = 9-2 = 7
Now,
f(x) = 9x+2 and
f(g(x)) = f(7) = 9x+2, (substitute x = 7)
f(g(x)) = 9×7 + 2
f(g(x)) = 65.
Thus, the value of the composite function f(g(x)) = 65.

How long does it take $450 to double at a simple interest rate of 14%? Express your answer in months. Round to the nearest whole number.
The number of months so that the investment gets double will be 86 months.
What is simple interest?Simple interest is the concept that is used in many companies such as banking, finance, automobile, and so on. The amount is given as,
A = P + (PRT)/100
Where P is the principal, R is the rate of interest, and T is the time.
The principal amount is $450 and if the amount gets doubled, then the value of the amount will be $900. The simple interest rate is 14%. Then the time is given as,
A = P + (PRT)/100
900 = 450 + [450 x 14 x T] / 100
450 = 450 x 14 x T / 100
T = 100 / 14
T = 7.14 years
T = 7.14 x 12
T = 85.7 ≈ 86 months
The number of months so that the investment gets double will be 86 months.

Draw LMN with vertices L(2,-2), M(7,-3), and N(5,2). Find the coordinates of the vertices after a 90 degree rotation about the origin and about each of the points L, M, and N.
The rotation of the vertices L(2,-2), M(7,-3), and N(5,2) are L'(-2, -2), M'(-7, -3), and N'(5, 2) respectively.
How does rotation by 90 degrees changes coordinates of a point if rotation is with respect to origin?Let the point be having coordinates (x,y).
If the point is in first quadrant:
Subcase: Clockwise rotation:
Then (x,y) → (y, -x)
Subcase: Counterclockwise rotation:
Then (x,y) → (-y, x)
We know that the rotation of a point (x,y) about the origin by 90° is (-y,x).
Given vertices of ΔLMN are L(2,-2), M(7,-3), and N(5,2).
Let consider the rotations of L, M, and N are L', M', and N' respectively.
The rotation of a point L(2,-2) about the origin by 90° is L'(-2,-2).
The rotation of a point M(7,-3) about the origin by 90° is M'(-7,-3).
The rotation of a point N(5,2) about the origin by 90° is N'(5,2).
Hence, the points L'(-2, -2), M'(-7, -3), and N'(5, 2) are the rotation of vertices.
Therefore, L, M, and N of ΔLMN about the origin by 90°.
Hence, The rotation of the vertices L(2,-2), M(7,-3), and N(5,2) are L'(-2, -2), M'(-7, -3), and N'(5, 2) respectively.

Tony's Used Car Dealership is selling a car for $12,000. This price represents a 20%
reduction from the original price of the car. What was the original price of the car?
The original price of the car is $15,000
Let us assume the original price of car be x. So, forming the equation to find the value of x and hence the original price of the car.
Equation -
x - 20% × x = 12000
x - 20/100×x = 12000
Cancelling zero as common in both numerator and denominator, on the left hand side of the equation
x - x/5 = 12000
Taking LCM on Left Hand Side of the equation
(5x - x)/5 = 12000
Rewriting the equation
4x = 12000 × 5
Performing multiplication on Right Hand Side of the equation
4x = 60,000
x = 60,000 ÷ 4
Performing division
x = 15,000
Therefore, the original price of the car is $15,000.

It is the end of the budgeting period for John Smith, and he has $500 left in his budget for car rental expenses. He plans to spend this budget on a sales trip throughout the country. He will rent a car that costs $50 per day and $ 0.50per mile, and he can spend no more than 500
The number of miles that John Smith can travel with his budget if he has $500 left in his budget for car rental expenses is 900 miles.
How to calculate the expression?Amount left in the budget = $500
Since he will rent a car that costs $50 per day and $ 0.50per mile, the expression will be:
50 + 0.50m = 500
where m = number of miles
Collect like terms
0.5m = 500 - 50
0.5m = 450
Divide
m = 450/0.5
m = 900
Therefore, the number of miles that John Smith can travel with his budget is 900 miles.
