The Minnitte family pool, PQRS, measures 48 feet by 84 feet
48 : 84 = 4 : 7
The Gaudet family pool, WXYZ, measures 40 feet by 70 feet
40 : 70 = 4 : 7
The two pools are similar
The similarity statements :
PQ/WX = QR/XY = RS/YZ = PS/WZ
Scale factor:
48/40 = 6/5
84/70 = 6/5
So
SF = 6/5
Answers: See each part below.
1) The scale factor on Map 1 is 1cm = 2 km. It is given in the key in the bottom right corner.
2) The length of the trail would be 16 km. Since each cm is 2 km, we multiply the 8 by 2 to get a total of 16.
3) The scale factor from the first map to the second map is 0.75. To find this we can write and solve the following equation to determine the change from Map 1 to Map 2.
8k = 6
k = 0.75
4) To find the lengths of the sides of the landmark, just change the mm into cm and use the scale factor for each.
5 mm is 0.5 cm. 0.5 x 2 = 1 km
3 mm is 0.3 cm. 0.3 x 2 = 0.6 km
4 mm is 0.4 cm. 0.4 x 2 = 0.8 km
15-8=7
that would be the equation and there would be $7 left
You would divide £52.65 by 27 to find out what 1 packet costs, thus leads us to £1.95. Then you would do £1.95 x 35 as there are 35 packets to get the answer £68.25
