The straight line distance is 5 miles from starting point.
Step-by-step explanation:
Driving 3 miles north and 4 miles east and then the straight line distance will form a right angled triangle.
Where;
One leg = a = 3 miles
Other leg = b = 4 miles
Hypotenuse = c
Using Pythagoras theorem;
Taking square root on both sides
The straight line distance is 5 miles from starting point.
Answer:
(a) The sale price of any book in the store is 0.70 <em>x</em>.
(b) The regular price of the book bought by Jerome was $12.80.
Step-by-step explanation:
The complete question is:
All books in a store are being discounted by 30%. Let x represent the regular price of any book in the store. (a) Write an expression that can be used to find the sale price of any book in the store. (b) Jerome bought a book on sale at the store. The sale price of the book was $8.96. Write an equation to determine the regular price of the book Solve your equation to find the regular price of Jerome's book to the nearest cent.
Solution:
The regular price of any book in the store is denoted by, <em>x</em>.
(a)
The discount percentage is: <em>d</em>% = 30%.
The sales price of the book is:
Sales Price = Regular Price - Discount
Thus, the sale price of any book in the store is 0.70 <em>x</em>.
(b)
The sales price f book bought by Jerome is, SP = $8.96.
Jerome bought the book at the same discount, i.e. 30%.
Compute the regular price of the book bought by Jerome as follows:
Thus, the regular price of the book bought by Jerome was $12.80.

Answer:
Container A is filling more quickly
Step-by-step explanation:
<em>Let us explain the linear relation</em>
The linear equation is y = m x + b, where
<em>If a line represents the amount of water over time, then it represents the rate of filling of the water</em>
∵ There are two containers A and B that have the same size
∵ The two lines represent the amount of water over time in
containers A and B
∴ The slopes of the lines represent the rat of water in the tanks
→ That means the greater slope represents the greater rate
∵ The greater the slope, the steeper the line
∴ The container that represented by the steeper the line is filling quickly
→ The line represents container A is steeper more than the line
represents container B
∴ Container A is filling more quickly
