it costs $24,893.75 to repay a loan of 17,500 at 6.5% annual interest. How many years does it take to repay the loan? I saw somebody asked this question, but the answer wasn't specific.

Answers

Answer:

11.5 years

Step-by-step explanation:

The formula for the monthly payment of a loan is:

[tex] A = P\dfrac{r(1 + r)^n}{(1 + r)^n - 1} [/tex]

where

A = monthly payment

r = interest rate per period

n = number of periods

Assuming a monthly payment, we have

P = 17500

r = 0.065/12

The total amount of payments is the monthly payment times the number of payments, so

An = 24893.75

We can try 10 years. n = 10 * 12 = 120

[tex] A = 17500\dfrac{\frac{0.065}{12}(1 + \frac{0.065}{12})^{120}}{(1 + \frac{0.065}{12})^{120} - 1} = 198.71 [/tex]

An = 198.71 * 120 = 23845.08

The total amount of payments is too low.

Let's try 11 years.

n = 11 * 12 = 132

[tex] A = 17500\dfrac{\frac{0.065}{12}(1 + \frac{0.065}{12})^{132}}{(1 + \frac{0.065}{12})^{132} - 1} = 185.92 [/tex]

An = 185.92 * 132 = 24540.90

The total amount of payments is still too low.

Let's try 12 years.

n = 12 * 12 = 144

[tex] A = 17500\dfrac{\frac{0.065}{12}(1 + \frac{0.065}{12})^{144}}{(1 + \frac{0.065}{12})^{144} - 1} = 175.34 [/tex]

An = 185.92 * 144 = 25248.41

The total amount of payments is too high.

11 years is too little, and 12 years is too much.

Let's try 11.5 years.

n = 11.5 * 12 = 138

[tex] A = 17500\dfrac{\frac{0.065}{12}(1 + \frac{0.065}{12})^{138}}{(1 + \frac{0.065}{12})^{138} - 1} = 180.39 [/tex]

An = 180.39 * 138 = 24893.20

11.5 gives a total of payments of $24,893.20 which is very close to $23.893.75.

Answer: 11.5 years

The total amount of payments is too high.

15x^2+166X+192

                      ANSWER  15x^2+116+192

Answer:

The chosen topic is not meant for use with this type of problem.

Step-by-step explanation:

The best way to try and solve is using the quadratic formula. The quadratic formula helps us solve any quadratic equation. First, we bring the equation to the form ax²+bx+c=0, where a, b, and c are coefficients. Then, we plug these coefficients in the formula: (-b±√(b²-4ac))/(2a) . See examples of using the formula to solve a variety of equations.

( 5x + 12 ) x ( 3x + 16 )

Step one : use the distributive factor. To “distribute” means to divide something or give a share or part of something. According to the distributive property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.

5x x 3x

5x x 16

12 x 3x

12 x 16

15x^2 + 80x + 36x + 192

Step two: Combine like terms

15x^2 + 116x + 192

Step three: Solve the equation for  x  by finding  a

,  b, and c of the quadratic then applying the quadratic formula.

x = - 12/5 , -16/3

Total area = 27+15 = 42

Step-by-step explanation:

For question 13, we still need to find the bottom side of the T-shape that's not labeled. That's just 9-3.5-3.5=9-7=2.

Now that we know all the side lengths, we can set up an equation where all the side lengths add up to 39, and solve for x:

9+3+3+3.5+3.5+x+x+2=39

24+2x=39

2x=15

x=7.5

For question 14, we can divide the shape into 2 rectangles, which is shown in the picture attaches. Then, we just solve for each rectangle's area separately, and then add them up.

Rectangle A = 9*3=27

Rectangle B = 7.5*2=15

Total area = 27+15 = 42

You purchase disposable plates, cups, and forks for a cookout. Plates are sold in packages of 24, cups in packages of 32, and forks in packages of 48. What are the least numbers of packages you should buy in order to have the same number of plates, cups, and forks?

Answers

Answer:

96 packages

Step-by-step explanation:

We solve for this question using Lowest Common Multiple (LCM) method

Step 1

We list multiples of each number until the first common multiple is found. This is referred to as the lowest common multiple.

From the question , we are told:

Plates are sold in packages of 24

Cups in packages of 32

Forks in packages of 48

Multiples of 24:

24, 48, 72, 96, 120, 144

Multiples of 32:

32, 64, 96, 128, 160

Multiples of 48:

48, 96, 144, 192

Therefore,

LCM(24, 32, 48) = 96

Hence, the least numbers of packages you should buy in order to have the same number of plates, cups, and forks is 96 packages

Subtract 1.3 from both sides of the equation, add 4x to both sides of the equation, then divide by the coefficient of x. Subtract 1.3 from both sides of the equation, subtract 4.6x from both sides of the equation, then divide both sides by the coefficient of x. Add 1.3 to both sides of the equation, subtract 4.6x from both sides of the equation, then divide both sides by the coefficient of x. Add 1.3 to both sides of the equation, subtract 4x from both sides of the equation, then divide both sides by the coefficient of x.

Answers

Answer:

its D

Step-by-step explanation:

got it correct on a test :)

The correct option is Option D: Adding 1.3 to both sides of the equation, subtracting 4x from both sides of the equation, then dividing both sides by the coefficient of x.

What is the linear equation?

The linear equation is an equation where the highest degree of the variables used in the equation is 1.

For example 9x+5=23

Given the equation is -1.3 +4.6x= 0.3+ 4x

In order to the linear equation first, try to keep the constant and the variable part to one side by adding or subtracting the constant term.

Then divide the coefficient of the variable (if the coefficient is not equal to 1) on both sides.

Here the given equation is -1.3 +4.6x= 0.3+ 4x

Step-1: Adding 1.3 to both sides of the equation

⇒-1.3 +4.6x +1.3 = 0.3+ 4x +1.3

⇒4.6x = 4x+1.6

Step-2: subtracting 4x from both sides of the equation

⇒4.6x -4x = 4x+1.6-4x

⇒ 0.6x=1.6

Step-3:  dividing both sides by the coefficient of x i.e. 0.6.

⇒0.6x/0.6 = 1.6/0.6

⇒x= 2.67

Therefore the correct option is Option D: Adding 1.3 to both sides of the equation, subtracting 4x from both sides of the equation, then dividing both sides by the coefficient of x.

Answers

Answer:

18.5 minutes

Step-by-step explanation:

Koto’s average velocity along her route was 4.5 m/s.

She started at her house and traveled 15,000 meters north, 5,000 meters east, 20,000 meters south, and then 5,000 meters west.

5000 meters west - 5000 meters east = 0

20,000 south - 15000 north = 5000 meters

4.5 meters = 1 second

5000 meters = x seconds

Cross Multiply

4.5 × x = 5000 × 1

x = 5000/4.5

x = 1111.11111111 seconds

There are 60 seconds in 1 minute.

60 seconds = 1 minute

1111.11111111 = y minutes

60 × y = 1111.11111111 × 1

Lindsey Smith was the top scorer in a women's professional basketball league for the 2006 regular season, with a total of 867 points. The number of two-point field goals that Lindsey made was 66 less than double the number of three-point field goals she made. The number of free throws (each worth one point) she made was 36 less than the number of two-point field goals she made. Find how many free throws, two-point field goals, and three-point field goals Lindsey Smith made during the 2006 regular season. How many free throws, 3 pointers, and 2 pointers did she make?

Answers

Answer:

Kindly check explanation

Step-by-step explanation:

Given that :

Total point = 867

Let :

number of 3 point goals = p

Number of 2 point goals = 2p - 66

Number of 1 point goals = (2p - 66) - 36 = 2p - 102

Hence,

3p + 2(2p - 66) + 2p - 102 = 867

3p + 4p - 132 + 2p - 102 = 867

3p + 4p + 2p - 234 = 867

9p - 234 = 867

9p = 867 + 234

9p = 1101

p = 122.33

2 pointer = 2p - 66

2(122.33) - 66 = 178.67

1 point = 2p - 102

2(122.33) - 102

= 142.67
