When Kevin bought a new bike ramp, he borrowed $1,200 at a rate of 18% for 9 months. How much interest did he pay?

AURORKA [14]

We would apply the formula for determining simple interest which is expressed as

I = PRT/100

I is the interest

P is the principal or initial amount

R = interest rate

T = time in years

From the information given,

P = 1200

r = 18

Since there are 12 months in a year,

T = 9/12 = 0.75

Thus,

I = (1200 x 18 x 0.75)/100

Interest = $162

We use (BODMAS) :

Brackets

Order/Index

Division

Multiplication

Addition

Subtraction

Now we do bracket first :

7(3²) = 7(9) = 63

Now we do division :

63÷3 = 21

Now we do multiplication :

2 × 21 = 42

A circle with circumference 20 has an arc with 72 degree central angle what is length of the arc

Debora [2.8K]

Answer:

Step-by-step explanation:

Look at the picture.

At the beginning we have to calculate what part of the angle 360° is the given angle 75°.

$\dfrac{75}{360}=75:360=0.2$

The same part of the circumference of the circle is the arc defined by this central angle.

The circumference C = 20.

Therefore

$x=0.2\cdot20=4$
