20.75 because if you add 4.85+7.95+7.95 add that you get 20.75
Answer:
Percent of rise of a new truck on a used truck = 15%
Step-by-step explanation:
Let x be the percentage of saved money if Jason buying a used truck.
Given:
Price of the used truck = $34,000
Price of the new truck = $40,000
We need to find the percent of rise Jason saves on a used truck rather than buying a new truck
Solution:
Using a percentage formula.

)
Using cross multiplication rule.



x = 15%
Therefore, Jason used 15% rise of a new truck for a used truck.
Answer:
option 2
Step-by-step explanation:
The problem can be solved using Pythagoras' identity for a right triangle.
The angle between due East and due North is 90°
The solution here involves using the Cosine rule.
let x be the direct distance between house and office, then
x² = 17² + 21² - 2(17)(21)cos90° → option 2
Note that since cos90° = 0 the equation reduces to
x² = 17² + 21² ← Pythagoras' identity
The 2 in 2783 is two thousand and the 2 in 7283 is 100
A way to remember is go from right to left!
ones, tens, hundred, and thousand
