The following statement are true:

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

So, 72/12 = 6 years

Thus, It will take 6 years to double the investment. This statement is true.

So, 72/18 = 4 years

Thus, It will take 4 years to double the investment. This statement is not true.

so, 72/8= 9 years.

Thus, It will take 9 years to double the investment. This statement is true.

So, interest = PRT/100

I  = (2000 × 0.05 × 20)

I = $2000

Thus, This statement is true.

Interest = ( 700 × 0.06 × 12 ) = $504

Amount after 12 years

=700 + 504

= $1204.

Thus, This statement is not true.

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.

Answer:

  32 degrees

Step-by-step explanation:

You want the smallest angle of a triangle in which the other two angles are 20 degrees larger than the smallest, and 3 times the smallest.

The sum of angles is 180 degrees. The three angles are x, (x+20), and (3x). Their sum is ...

  x +(x +20) +3x = 180

Collecting terms gives ...

  5x +20 = 180

  5x = 160 . . . . . . subtract 20

  x = 32 . . . . . . divide by 5

The smallest angle is 32 degrees.

Answer:333R1 or as a mixed fraction 33 1/3. I believe this is right :]

Step-by-step explanation:

The given equation of the straight line is y +8x+10=0

We are required to find the equation of a straight line passing  through the point (-2, 6) and has a slope of -8.

An equation of a straight line can be easily found if the slope and any of the points is given

The general form of equation is given by

y-y1 = m (x-x1)

where x1,y1 is the coordinate of the known point

m is the slope of the line

It is given that the coordinate of the known point is (-2,6)

the slope is given to be -8

Thus using these values to form the equation,

y-6 = -8 (x--2)

y-6 = -8 (x+2)

y-6 = -8x-16

y+8x-6+16=0

y+8x+`10=0

Hence, The straight line equation is y +8x+10=0

Using the together rate, it will take more 3.45 days to complete the work.

Division is one of the four basic operations of arithmetic, the ways that numbers are combined to make new numbers. The other operations are addition, subtraction, and multiplication.

The together rate is given by the sum of each separate rate.

For this problem, the rates are given as follows,

Ann,1/10 = 0.1

Ben,1/12 = 0.0833

Together,1/x

Hence the amount completed in 2 days is:

2 x (0.1 + 0.0833) = 0.3666

The amount it would take them to complete 100% of the project working together is found by the together rate as follows,

x = 60/11

x = 5.45 days.

The time it would take to do the remaining 100 - 36.66 = 63.34% of the project is,

0.6334 x 5.45 = 3.45 days.

Considering the definition of combination,  if a family has 5 children, in 10 ways the parents can have 2 boys and 3 girls as children.

Combinations of m elements taken from n to n (m≥n) are called all the possible groupings that can be made with the m elements in such a way that not all the elements enter; the order does not matter and the elements are not repeated.

To calculate the number of combinations, the following expression is applied:

[tex]mCn=\frac{m!}{n!(m-n)!}[/tex]

where "!" indicates the factorial of a positive integer, which is defined as the product of all natural numbers before or equal to it.

If a family has 5 children, you can know that:

So, you can observe that 5C3 is equal to 5C2. Then:

5C3 = 5C2 = [tex]\frac{5!}{3!2!}[/tex]= 10

The value of the composite function f(g(x)) is calculated as f(g(x)) = 65.

Composite functions is one in which one function is placed within another.

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.

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.

The number of months so that the investment gets double will be 86 months.

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

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.

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
