The distance between starting and ending point is 34 miles.
Step-by-step explanation:
Given,
Car moves 16 miles to north then 30 mile to east.
It forms a right angle triangle.
The straight line distance from starting to ending point represents hypotenuse.
To find the distance between starting and ending point.
Formula
By <em>Pythagoras theorem,</em>
h² = b²+l² where h is the hypotenuse, b is base and l is the another side.
Taking, b=16 and l=30 we get,
h² = 16²+30²
or, h =
or, h = = 34
Hence,
The distance between starting and ending point is 34 miles.
So firstly, let's figure out the expression for a singular goody bag. Since there's 2 of each item, a single goody bag is going to be
Now since we have 7 friends who are all getting 1 goody bag, multiply the cost of the goody bag by 7, and our expression is . Now we can solve it from there.
Firstly, solve the multiplication inside the parentheses:
Now add up what's inside the parentheses:
Lastly, multiply and <u>your answer will be $56.56</u>
