Natalie earned $200 in interest and 30 months with a beginning balance of $1040. What was her interest rate?

rjkz [21]

The interest rate is 7.69%

Step-by-step explanation:

Given

Interest = $200

Time = t = 30 months

Time will be converted into years as the rate is applied yearly

So,

1 year = 12 months

30 months = 30/12 years = 2.5 years

Principal amount = $1040

The formula for interest is:

$I = P*r*t$

Putting the values

$200 = 1040 * r * 2.5\\200 = 2600r\\r = \frac{200}{2600}\\r = 0.076923$

Converting into percentage:

r = 7.6923

Rounding off to nearest hundredth

r = 7.69%

Hence,

The interest rate is 7.69%

HELPP WORTH 30 points!!

yuradex [85]

Step-by-step explanation:

11pi/6 in radians.

pi = 180°

so,

pi/6 = 180/6 = 30°.

11pi/6 = 11×pi/6 = 11×30 = 330° or -30°.

the reference angle is the smallest (measured in absolute values) angle to the horizontal (x) axis.

so, that is then 30°.

so, which statements are true, and which are false ?

sin(330°) = -1/2, because the angle is in the 4th quadrant and therefore below the x-axis, which makes the sine values negative.

sin(reference angle = 30°) would be +1/2, but that was not the statement.

so, this statement is false.

the reference angle is 60°.

since we can see that it is actually 30°, this statement is false.

the reference angle is 30°.

yes, that is true.

cos(330°) = sqrt(3)/2.

yes, that is true.

this cosine is on the right side of the y-axis and therefore positive.

tan(330°) = 1.

as tangent = sine/cosine, to be equal to 1 means that sine = cosine. which is not the case here.

this statement is false.

the reference angle is 45°.

no, as 3. had shown, it is 30°.

so, this statement is false.
