A blender that normally costs $130 is on sale for 12% off. What is the final cost of the blender if there is also an 8% sales ta
polet [3.4K]

Answer:

$105.25

Step-by-step explanation:

First we need to know to price of the blender after the sale, so we are going to pay the 88% of the blender's price so the final price without the sale tax is going to be

\$130\times .88=\$ 114.4      (1)

Knowing this price we need to calculate the 8% of the total price

\$ 114.4 \times .08=\$ 9.152    (2)

We substract the result (2) from (1)

\$ 114.4 - \$ 9.152 = 105.248

Rounding this number to nearest cent the final result is:

$105.25

Given that sine of theta = 21/29, what is the value of cosine of theta, for 0° &lt; theta &lt; 90°?
fenix001 [56]

If the value of θ is 46.4°. Then the value of the cosine of θ will be 20/29.

<h3>What is trigonometry?</h3>

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

The value of sine of θ is 21/29.

Then the value of θ will be

sin θ = 21/29

     θ = sin⁻¹(21 / 29)

     θ = 46.4°

Then the value of the cosine of θ will be

cos θ = cos 46.4°

cos θ = 20/29

More about the trigonometry link is given below.
