The sales tax on a digital camera is $7.15. What is the sales tax rate?

Answers

Answer 1

Answer: You just have to find out the percent 7.15 is of 105. To do that, you set up a proportion with x as the percentage:

$(7.15)/(105)=(x)/(100)$

Then, cross multiply to get:

$(7.15)/(105)=(x)/(100)\n715=105x\n105x/105=715/105\nx=6.810$

So, the sales tax rate was 6.8%.

In triangle ABC, angle A measures 33 degrees and angle C measures 122 degrees. What is the measure of angle B?

Answers

Answer:

∠ B = 25°

Step-by-step explanation:

the sum of the three angles in a triangle = 180° , that is

∠ A + ∠ B +∠ C = 180° ( substitute values for A and C )

33° + ∠ B + 122° = 180° , that is

155° + ∠ B = 180° ( subtract 155° from both sides )

155° - 155° + ∠ B = 180° - 155° , that is

∠ B = 25°
