How much should you invest at 2.4% simple interest in order to earn $75 interest in 7 months?

Answers

Answer 1

In order to earn $75 interest in 7 months at 2.4% invest 53.571.

What is simple interest?

Generally, simple interest paid or received over a certain period is a fixed percentage of the principal amount that was borrowed or lent.

Simple interest is calculated using the following formula:

Simple Interest = P×R×T where:

P=Principal amount

R=Annual interest rate

T=Term of loan, in years

According to the given question

Given that

Simple interest= 75

Time= 7/12= 0.583

Rate of interest= 2.4

Principle amount=?

S.I= PTR

75 = P x 0.583 x 2.4

75 = P x 1.4

P = 75 / 1.4

P= 53.571

Therefore, principle is 53.571

(Do not round until the final answer. Then round to the nearest cent as needed.)

Answers

The final amount compounded monthly at a rate of 8% over 6 years on a principal of $5300 is $8551.56

Compound Interest

Compound interest is the interest calculated on the principal and the interest accumulated over the previous period. It is different from simple interest, where interest is not added to the principal while calculating the interest during the next period.

The formula of compound interest as given in the questions is

A = Final amount P = principalr = ratet = timen = number of times compounded

A = P[(1 + r/n)^nt

Substituting the values into the formula

A = 5300(1 + 0.08/6)^12 * 6

A = 8,551.56

Erica will owe $8551.56

How do you find equivalent in math?

Answers

To find equivalent expression in math is the fractions with distinct numerators and denominators but the same value are said to be equivalent fractions.

In mathematics, equivalent fractions are those with the same denominator and differing numerators.

The multiplicity of a member of a multiset in mathematics is the number of times the member appears in the multiset. The multiplicity of a root, for instance, is how many times a given polynomial has a root at a particular point.

It's crucial to understand the concept of multiplicity in order to correctly count without mentioning exceptions (for example, double roots counted twice). Thus, "counted with multiplicity" is used.

This can be highlighted by counting the number of different elements, as in "the number of separate roots," if multiplicity is disregarded. However, multiplicity is always taken into account when a set (as opposed to a multiset) is established, therefore the word "different" is not necessary.

For instance, if we simplify 5/15, we get a fraction that is equal to 1/3, which is equal to 5/15.

The value of x is 19 and the measure of angles in triangle ABC are 75°, 75° and 30° respectively.

What is a triangle?

triangle is a three-sided polygon that consists of three edges and three vertices. The most important property of a triangle is that the sum of the internal angles of a triangle is equal to 180 degrees. This property is called angle sum property of triangle.

If ABC is a triangle, then it is denoted as ∆ABC, where A, B and C are the vertices of the triangle. A triangle is a two-dimensional shape, in Euclidean geometry, which is seen as three non-collinear points in a unique plane.

The sum of ∠A + ∠B + ∠C = 180°( sum of angles in a triangle )

3x + 18 + 7x - 58 + 2x - 8 = 180°

12x -48° = 180°

12x = 228

x = 228/12

x = 19

but ∠A = 3x + 18, but x = 19

∠A = 3(19) + 18 which is 75°

Also ∠B = 7x -58

∠B = 7(19) - 58 which is 75°

∠C = 2x -8

∠C = 2(19) - 8 which is 30°

Divide the numerator and denominator by the GCF to reduce a fraction. (This is also referred to as "writing a fraction in the simplest terms.") The common factors are sometimes shown to be "cancelled." It is worth noting that the result is an equivalent fraction in its simplest form.

How do you divide the numerator to the denominator by GCF?

To put it simply, we must divide the numerator (x) by the denominator (y) to simplify it. For example, after simplifying 3 6, represent it as a fraction and identify the numerator and denominator. 3 6 can be written as 3/6. Further simplification yields 1/2.

Let's pretend the fraction is a proper fraction. The denominator is the numerator. We want to reduce the fraction to its simplest form.

a) Use Numerator =Remainder* as the denominator.

Now Numerator >Remainder* b)Numerator Remainder*=Remainder** c) ••• (keep going until Remainder =0)

d) When the Remainder equals zero, the Divisor is the GCD (or GCF, as you say). GCF is a misnomer because it only deals with numbers. Only the term GCF applies to variables (with numerical values, as in algebraic expression).

Let us look at an example.

407/3367 is the fraction.

As evident, the numbers407 ,3367 does not appear to have share Divisors 2 or 3 or 5 or 7 or 11 from prima facie considerations. So we may take recourse of successive division method.

3367 ÷407 =Remainder 111 (quotient 8)

407 ÷ 111 =Remainder 74 (quotient 3)

111 ÷74=Remainder 37 (quotient 1)

74 ÷37 =Remainder 0 (ZERO )

Here 37 divides leaving Remainder zero. Therefore the GCD is 37

Answers

Cindy's monthly payment of $609.63 will cost her $29,262.24 in 4 years at a 4% APR.

How is the total cost determined?

The total cost that Cindy will spend on the car which costs $27,000 is computed by multiplying the monthly payment by 48 months (the payment period).

The monthly payment can be determined using an online finance calculator that compounds the interest rate monthly for four years.

Cost of car = $27,000

Annual Percentage Rate (APR) = 4%

Payment period = 4 years (monthly)

N (# of periods) = 48 months (4 years x 12)

I/Y (Interest per year) = 4%

PV (Present Value) = $27,000

FV (Future Value) = $0

Results:

PMT = $609.63

Sum of all periodic payments = $29,262.24

Total Interest = $2,262.45

Thus, Cindy will spend $29,262.24 for a car that costs $27,000, if she repays monthly for 4 years.

Dolphins and other sea creatures can leap to great heights by swimming straight up and exiting the water at a high speed. A 230kg dolphin leaps straight up to a height of 6.4 m When the dolphin reenters the water, drag from the water brings it to a stop in 1.5 m

Answers

The motion of the dolphin, evaluated using the kinematic equations and Newton's second law of motion are;

The time it takes the dolphin to stop is about 0.268 secondsThe force of the water on the dolphin is about 9626.88 N

What is the Newton's second law of motion?

Mathematically, Newton's second law of motion states that force is the product of mass and acceleration.

The mass of the dolphin = 230 kg

Height to which the dolphin leaps = 6.4 m

The distance the drag brings the dolphin to a stop = 6.4 meters

First part;

The time it takes the dolphin to stop can be found from the equation;

At the water surface;

m·g·h = 0.5·m·v² (conservation of energy)

g·h = 0.5·v²

v² = 2·g·h

Therefore;

v² = 2 × 9.81 × 6.4 = 125.568

In the water, the initial velocity is v, the velocity at 1.5 meters depth is u, we get;

u² = v² - 2·a·s

Therefore;

v² = 2·a·s

a = v²/(2·s)

a = 125.568/(2 × 1.5) = 41.856

a = 41.856 m/s²

v = u - a·t

t = (u - v)/a

Therefore;

t = (√(125.568))/41.856 ≈ 0.268

The time it takes the dolphin to stop is about 0.268 seconds

Second part

Newton's second law of motion states that force is directly proportional to the rate of change of momentum produced

Mathematically

Force = Mass × Acceleration

Force on the dolphin, F = 230 kg × 41.856 m/s²= 9626.88 N

Now,

Since, In ΔSTU, s = 250 inches, ∠U=17° and ∠S=52°.

Hence, ∠ T = 180 - (17 + 52)

∠ T = 180 - 69

∠ T = 111°

Now, We use the sin rule as;

Step-by-step explanation:

Tony bought a shirt for a friend's birthday for $27.00. He liked the shirt so much that he returned to the store a week later to buy a shirt for himself. Tony found the price of the shirt had changed to $32.13. Rounded to the nearest whole percent, what is the percent increase in the price of the shirt?

Answers
