You are going to a friend's house to watch a movie. If you drive on Street C, the distance is 3 miles. You need to stop at the movie store on Street A. The store is 1 mile from your house. What is the distance you will drive on Street B from the movie store to your friend's house? (right triangle)
Answers
Answer:
miles
Step-by-step explanation:
In the figure, let P be yours house and Q be your's friend's house. Let R be the movie store.
Note that the distance from your house and to your house on Street C is 3 miles.
The distance from your house and to the move store on Street A is 1 mile.
Now, the distance from the move store to your friend's house is the hypotenuse of the right triangle ΔPQR.
The distance from the move store to your friend's house is RQ.
In the right triangle ΔPQR,
=
= 10
Hence, the distance from the move store to your friend's house is miles.

The cost of 2 tv is 4 times more cost one DVD ;
The cost of 2 tv and 3 DVD player is 7 times more cost one DVD ;Then, 1 DVD cost 1421 ÷7 = 201 $ ;
1 tv cost = 2 * 201 = 402 $ ;
Final answer:
To solve the problem, you set up two equations based on the information given. Then, you substitute one equation into the other to solve for the cost of the TV, which comes out to be approximately $405.43.
Explanation:
To answer this question, you need to use algebra. We can create two equations based on the information given. Let's say the cost of a TV is x and the cost of a DVD player is y. According to the problem, we have two equations:
- 2x + 3y = $1421 (This comes from the total cost of the 2 TVs and 3 DVD players)
- y = 0.5x (This comes from the fact that the cost of a DVD player is half the cost of a TV)
We can then substitute the second equation into the first to get:
- 2x + 3(0.5x) = $1421
- 2x + 1.5x = $1421
- 3.5x = $1421
To find the cost of the TV 'x', you can divide both sides of the last equation by 3.5 resulting in x = $405.43. So the cost of one TV is approximately $405.43.
