russell bought a CD player that costs $120 before it went on sale for 15% discount. If he paid 5% sales tax on the sale price, h

Masja [62]

Answer:

$107.10

Step-by-step explanation:

The original price of the CD player is $120 and we need to take 15% off.

We can find how much we need to subtract by multiplying 120 by .15, which equals 18. Then we can subtract that from 120, to get a sales price of $102.

A shortcut is subtracting 15 from 100 to get 85, and then doing 120*.85 = 102.

From the sales price of 102, there's a 5% tax to add on. 102 * .05 = 5.1

102+5.1 = 107.1

Answer:

$\theta \approx 1.23^\circ$

Step-by-step explanation:

The expression has been given as:

$tan(\theta) = \frac{50}{18}$

Required: Find $\theta$

Simplify the fraction

$tan(\theta) = 2.7778$

Take arc tan of both sides

$\theta = tan^{-1}(2.7778)$

$\theta \approx 1.23^\circ$

Find the measure of angle ABC. A. 124 B. 97 C. 56 D. 51

Airida [17]

Answer: Last Option

Step-by-step explanation:

By definition the sum of the internal angles of a triangle must always be equal to 180 °.

This means that:

$32 + (2x-15) + (x-5)=180$

Now we solve the equation for the variable x

$32 + 2x-15 + x-5=180$

$2x+x +32-15-5=180$

$3x +32-20=180$

$3x +12=180$

We subtract 12 in both barks of the equation

$3x +12-12=180-12$

$3x=168$

Divide by 3 on both sides of the equation

$\frac{3}{3}x=\frac{168}{3}$

$x=\frac{168}{3}$

$x=56$

Finally the measure of angle ABC is: (56-5)° = 51°
