Answer:
a. The length of a straight line between the school and the fire station is 4.6 miles
b. The length of a straight line between the school and the hospital is 2.1 miles
Step-by-step explanation:
See attachment
Given.
Distance between the school and the town hall = 4.3 miles directly east
Distance between the fire station and the town hall = 1.7 miles directly north.
The length of a straight line between the school and the fire station is calculated by solving the length of hypotenuse of the right angled triangle (see attachment A)
Using Pythagoras theorem;
x² = 1.7² + 4.3²
x² = 2.89 + 18.49
x² = 21.38 --- Take square roots
x = 4.6 miles
The length of a straight line between the school and the fire station is 4.6 miles
b.
The length of a straight line between the school and the hospital is calculated by solving the length of hypotenuse of the right angled triangle (see attachment B)
Using Pythagoras theorem;
x² = 1.7² + 1.2²
x² = 2.89 + 1.44
x² = 4.33 --- Take square roots
x = 2.1 miles
The length of a straight line between the school and the hospital is 2.1 miles

Answer:
810 stickers.
Step-by-step explanation:
Since there are 18 stickers per page, we need to use multiplication to calulate how many stickers we have total.
Our problem is 45*18, since we have 45 pages, each with 18 stickers.
45*18=810
Cindy has 810 stickers in all.

Answer:
$168.75
Step-by-step explanation:
if it's narked down by 20% then $135 is 80% of the original price
80 = 135
100 = x
80x = 100×135
x = $168.75
A bike is on sale for $135. The original price of bike is 135
Solution:
Given that bike is on sale for $ 135
The mark down price is 20 %
We need to find the original price of the bike
Hence we can say that,
Selling price of bike = 135
Mark down price = 20%
Original price of bike = ?
The cost price is given as:
By substituting the values we get,
Hence the original price of bike is $ 168.75
