You plan to buy $12,000 in computers at a local chain store. There are two stores located about the same distance from your office but in different cities with different tax rates. One city has a tax rate of 7% and the other has a tax rate of 8.5%. What percent can you save by going with the lower tax rate? Round your answer to the nearest tenth of a percent, if necessary.

Answers

lets calculate the taxes that would been payed at each city:
city1 = 12000(7%) = 12000(0.07) = 840
city2 = 12000(8.5%) = 12000(0.085) = 1020
So if you go to city1 instead of city2, you save 1020 - 840 = 180
So you would save $180 from $12000, that is:
 180 out of 12000
= 180/12000
= 0.015
and that is the 1.5%, that is what you could save

In XYZ, a right angled triangle, Z=90 degrees. Given that X=58 degrees, and XZ is 4.9m, find the length of XY

Answers

Answer:

XY ≈ 9.2 m

Step-by-step explanation:

using the cosine ratio in the right triangle

cos58° = (adjacent)/(hypotenuse) = (XZ)/(XY) = (4.9)/(XY) ( multiply both sides by XY )

XY × cos58° = 4.9 ( divide both sides by cos58° )

XY = (4.9)/(cos58) ≈ 9.2 m ( to the nearest tenth )

In aboard game you determine the number of spaces you msy move by spinning a spinner and rolling a die. The spinner has three regions: half of the spinner is marked"5" and the other half is equally divided between "10" and "20". The six faces of the die show 0,0,1,2,3,and 4 spots. When its your turn, you spin and roll, adding the numbers together to determine how far you may movefind the mean and standard deviation of the spiner results after you create a probability model for the outcome on the spinner
