Skis at a sports store near Snow Summit are on sale for $475. If the original price was $500,what discount rate(percent change)
Pani-rosa [81]

Answer: 5%

Step-by-step explanation:

Hi to answer this question, first we have to calculate the discount amount:

Original price - sale price

500-475 =25

Now, the original price (500) multiplied by the percent discount in decimal form (x) must be equal to the discount amount (25)

500x =25

Solving for x

x =25/500 =0.05

Multiply it by 100 to express in percentage form.

0.05 x 100 = 5%

Feel free to ask for more if needed or if you did not understand something.

Determine the measure of the missing angle in each triangle? <br> Please help me ASAP
IrinaK [193]

Answer:


Step-by-step explanation:

Sum of angles in a triangle = 180

1. 180 = 78 + 37 + x

180 = 115 + x

Subtract 115 from both sides

180 - 115 = 115 + x - 115

180 - 115 = x

65 = x

x = 65°


2. 180 = 80 + 66 + x

180 = 146 + x

Subtract 146 from both sides

180 - 146 = 146 + x - 146

34 = x

x = 34°
