Noel Devine bought a new dishwasher for $320. He paid 20 down and made 10 monthly payments of $34 what actual yearly interest rate did Noel pay?

Answers

Answer 1

IN finding the interest we need to use the following formula:
Interest= Principal x Rate x Time or I= PRT
Substitute values: I= [$20 + ($10 x $34)] -320 =$40
P= $320
R=?
T=10 months/year
I=PRT
Since R is a missing term, we will solve for R using this formula: R=I/PT
R= [$20 + ($10 x $34)-320] / ($320 x 10 months)
T=10 months÷12 months=0.83
R= ($40)/ $320 X 0.83
R= 40/ 265.6
R=15.06024096

Answer 2

First we need to find the amount financed, total payments and total interest

Amount financed
320-20=300

Total payments
34×10=340

Total interest=total payments-amount financed
Total interest=340-300=40

Now to find the yearly interest rate use the formula of
I=(2yc)÷(m×(n+1))
I ?
Y number of months in a year 12
C total interest 40
M amount financed 300
N number of payments 10
I=(2×12×40)÷(300×(10+1))
I=0.2909×100=29.09%

Hope it helps!

The sum of the square of a positive number and the square of 5 more than the number is 37. What is the number?

Answers

Writing this info out symbolically:

x^2 + (x+5)^2 = 37
Expanding, x^2+x^2+10x +25=37, or 2x^2+10x-12=0.
Reducing, x^2+5x-6=0. factoring, (x-1)(x+6)=0
Solving for x: x-1=0 results in x=1; x=6=0 results in x=-6.

We want only a positive result, so choose x=1 and discard x=-6.

Student to faculty is 17:3 The total is 740 how many students and faculty are at the college

Answers

Let the faculties be X and the number of students be Y.
X/Y = 17/3
3X= 17Y
X=17Y/3
Let that be equation 1
We also know that X+Y = 740. Let it be equation 2
Substitute equation 1 in equation 2
(17Y/3)+Y= 740
20Y/3 = 740
Y=111
Since the total is 740, then X equal 740-111 =629.
The number of faculties is 111 and the number of students is 629.

17+3 =20

so for every 20 people there are 17 students and 3 faculty

740/20 = 37

37*3 = 111 faculty

37 *17 = 629 students

Number of five grader students = 38

One van can hold = 9 students.

The number of vans needed to hold 38 students:

= 38 / 9

= 4.2 vans

This means we need 5 vans to accommodate all 38 students because in 4 vans only 36 students will be accommodated and 2 students remaining will need a van.

Thus the number of vans they will need for everyone to get to the art museum is 5.

A 3x3x4 cuboid is painted blue and cut into 1x1 cubes. what is the expected value for the painted sides of a randomly selected cube?

Answers

A 3 x 3 x 4 cuboid can be cut into 3(3) (4) = 36 pieces of 1 x 1 cubes.

Out of the 36 pieces of 1 x 1 cubes, there are no 1 x 1 cube with the four sides painted, there are eight 1 x 1 cubes with simply 3 sides painted, there are twenty 1 x 1 cubes with only 2 sides tinted, there are 6 cubes with only 1 side painted and there are 2 cubes with no side painted.

The chance that the four sides of a randomly selected cube is painted is 0.

The likelihood that only 3 sides of a randomly selected cube is painted is 8 / 36 = 2 / 9.

The chance that only 2 sides of a randomly selected cube is painted is 20 / 36 = 5 / 9.

The likelihood that only 1 side of a randomly selected cube is painted is 6 / 36 = 1 / 6.

The probability that no side of a randomly selected cube is painted is 2 / 36 = 1 / 18.

Thus, the expected value for the painted sides of a randomly selected cube is given by 4(0) + 3(2 / 9) + 2(5 / 9) + 1(1 / 6) + 0( 1 / 18) = 2 / 3 + 10 / 9 + 1 / 6 = 35 / 18 = 1.94

At a recent boat show, Boater's Paradis sold five more boats than Pelican Marine sold. If together they sold 33 boats, how many were sold by each company?

Answers

Paradise = 19 Pelican = 14

Final answer:

In this mathematics problem about boat sales, Pelican Marine sold 14 boats and Boater's Paradis sold 19 boats. This conclusion was achieved by forming and solving a simple algebraic equation based on the provided problem information.

Explanation:

To solve this problem, let's visualize it first. Pelican Marine sold a certain number of boats, and Boater's Paradis sold 5 more than that. If we call the number of boats sold by Pelican Marine as x, and adding Boater's Paradis' sales (x + 5), together they sold 33 boats. So we form the equation as x + (x+5) = 33.

Solving that equation, we will get 2x + 5 = 33, then simplify it to 2x = 28 after subtracting 5 from both sides. Finally, we divide both sides by 2 we get x = 14.

So, Pelican Marine sold 14 boats and Boater's Paradis sold 19 boats (14 boats Pelican Marine sold plus an additional 5 Boater's Paradis sold).

Identify the percent of change as an increase or a decrease. 68 miles to 42.5 miles

Answers

This is a decrease of 68 - 42.5
------------ = 0.375 = 37.5% decrease
68

Final answer:

The distance changing from 68 miles to 42.5 miles represents a 37.5% decrease, calculated using the percent change formula.

Explanation:

The question involves calculating the percent of change when the distance changes from 68 miles to 42.5 miles. To find the percent of change, we use the formula: Percent Change = ((New Value - Original Value) / Original Value) x 100%. Here, the original value is 68 miles and the new value is 42.5 miles.

Plugging in the values, we get: Percent Change = ((42.5 - 68) / 68) x 100% = (-25.5 / 68) x 100% ≈ -37.5%. Because the result is negative, this indicates a decrease in the distance traveled.

Therefore, the distance changing from 68 miles to 42.5 miles represents a 37.5% decrease.

How do I use the info given in the table to figure out the answers?

Answers

This is how you interpret the data and use it to solve the problem.

You can do this as direct proportion problem.

The number of gallons filled is proportional to the number of hours, and the rate of filling is:

rate = number of gallons / number of hours

From the two data in the second column you have:

number of hours = 3/4 h = 0.75 h

number of gallons = 637 + 1/2 gallons = 637.5 gallons

=>rate = 637.5 gal / 0.75 h = 850 gal/h

In the second column you have the number of hours and want to find the number of gallons, so assuming direct proportionality:

number of hours = 1/4 = 0.25

rate = 637.5 / 0.75 = x / 0.25

=> x = 0.25 * rate = 0.25 h * 850 gal/h = 212.5 gallons.

And from the third column:

number of hours = 1 + 1/2 hours = 1.5 hours

rate = x / 1.5 => x = 1.5h * rate = 850gal/h * 1.5h = 1275 gallons

With that you have already solved a. and b.

You should know how to answer c. and d. This is how:

c. number of gallons = 5.5 hours

number of gallons = rate * number of hours = 850 gal/h * 5.5 h = 4675 gal.

d. number of gallons = 100 gal

rate = 100 gal / number of hours => number of hours = 100 gal / rate

=> number of hours = 100 gal / 850 gal/h = (2/17) h

Pass to minutes => (2/17) h * 60 min/h ≈ 7 min

Given that (-2,-5) is on the graph of f(x), find the corresponding point for the function f(-2/3x).

Answers

f(cx) can be expressed as: point (a,b) goes to (a/c,b)
Then f(-2/3x) for point (-2,-5) is ((3/-2)(-2),-5) = (3,-5)

The corresponding point for the function f(-2/3x) given the point (-2,-5) on the graph of f(x) is (3,-5), where the x-coordinate is transformed by multiplying -2 by -3/2 and the y-coordinate remains unchanged.

The question asks about finding a corresponding point for the function f(-2/3x) given that the point (-2,-5) is on the graph of the original function f(x). To find the corresponding point, we need to apply the transformation to the x-coordinate of the given point. Since the function is f(-2/3x), this represents a horizontal stretch by the reciprocal of -2/3, which is -3/2. Therefore, we multiply the x-coordinate of the given point by -3/2.

Let's calculate this step by step:

Start with the original point (-2,-5).Apply the transformation to the x-coordinate: -2 multiplied by -3/2 equals 3.The y-coordinate remains unchanged because the transformation applies only to the x-coordinate.
So the corresponding point on the graph of the function f(-2/3x) based on the point (-2,-5) from f(x) is (3,-5).
