What is the annual interest rate if $1600 is invested for 6 years and $456 in interest is earned
sergij07 [2.7K]
Use the formula   i = p*r*t:
                                                               $456
$456 = $1600*r*6.  Solving for r, r = ----------------- = 0.0475, or 4 3/4%
                                                           ($1600)(6)

A television was originally priced at $598.00. The price was reduced by 6%. What is the new price of the television?
aksik [14]
Hello.

To find the answer of this question, you need to find 6% of 598. 
6 / 100 = 0.06. 0.06 x 598 = 35.88. So now all you have to do is subtract 35.88 from 598. 598 - 35.88 = 562.12.

So the new price of the television is 562.12.

Have a great day! :)

Solve for m < L
s2008m [1.1K]

The cosine is the ratio of hypotenuse and base. Then the measure of the angle ∠L will be 60°.

<h3>What is trigonometry?</h3>

The connection between the lengths and angles of a triangular shape is the subject of trigonometry.

The right-angle triangle is given below.

The length of the hypotenuse is 16 and the base length is 5.

Then the measure of the angle ∠L will be

cos L = 5 / 10

cos L = 1 / 2

      L = cos⁻¹ (1 / 2)

      L = 60°

More about the trigonometry link is given below.

You can represent the measures of an angle and its complement as x° and (90 − x)°. Similarly, you can represent the measures of
UNO [17]
X = 4(180 - x)
x = 720 - 4x
4x + x = 720
5x = 720
x = 720/5
x = 144

180 - x =
180 - 144 =
36

the measure of the angle is 144...the measure of its supplement is 36
