My total owed with interest is $507.50. I borrowed $290 at 12.5% interest.How long was my loan for in years?
lapo4ka [179]

Answer:

Time = 6 years

Step-by-step explanation:

Data;

Simple interest = $507.50

Principal = $290

Rate = 12.5% = 12.5/100 = 0.125

Time = ?

To solve this question, we'll need to use the formula for simple interest

S.I = PRT / 100

Or

S.I = P(1 + RT)

S.I = simple interest

P = principal

R = rate

T = time

S.I = P(1 + RT)

507.50 = 290(1 + 0.125*T)

507.50 = (290 × 1) + (290 * 0.125T)

507.50 = 290 + 36.25T

Solve for T

36.25T = 507.50 - 290

36.25T = 217.50

T = 217.50 / 36.25

T = 6

The time tenure on the loan was 6 years

Use the properties of 30-60-90 and 45-45-90 triangles to solve for x in each of the problems below. Then decode the secret messa
diamong [38]

These problems are solved using the trigonometric function. Trigonometric functions provides the ratio of different sides of a right-angle triangle.

<h3>What are Trigonometric functions?</h3>

The trigonometric function refer to function that are periodic in nature and which lend insight to the relationship between angles and the sides of a triangle that is right angled.

The solutions to x in the respective problems is given as follows:

1st.) x = 5 /Sin(30°)

x = 10

!) sin(45°) = 4/x

x = 4/sin(45°)

x = 4√2

I) Cos(45°) = √3 / x

x = √3 / Cos(45°)

x = √6

E) Tan(60°)

= (3√3) / x

x = (3√3) / 3

W) It is to be noted that for right-triangle that is isosceles in nature, the angle made by the legs and the hypotenuse is always 45°.

x = 45°

N) x² + x² = (7√2)²

x = 7

V) Tan(60°) = 7 / x

x = 7√3/3

K) x² + x² = (9)²

x = 9/√2

Y) Sin(60°) = 7√3/x

x = 14

M) Sin(30°) = x/11

x = 11/2

T) Sin(45°) = x/√10

x = √5

A) x + 2x + 90° = 180°

x = 30°

O) Sin(45°) = √2 / x

x = 2

R) Tan(30°) = x / 4

x = 4/√3

= 4√3 / 3

S) Sin(60°) = x / (10/3)

x = (5√3) / 3
