Answer:
4 : 25
Step-by-step explanation:
Given the ratio of 2 similar figures = a : b, then
ratio of areas = a² : b²
Given the similarity ratio = 2 : 5, then
ratio of areas = 2² : 5² = 4 : 25
Answer:
it took him 10 mintues to run 5 laps
Step-by-step explanation:
Answer:
Step-by-step explanation:
The two x angles on the right are supplementary which means they add up to 180 degrees
5x + 12 + 7x - 24 = 180
12x - 12 = 180
12x = 192
x = 192/12
x = 18
5x + 12 and y are corresponding angles and are therefore equal
5(18) + 12 = 90 + 12 = 102
Therefore y = 102
for 1 batch of pancake = 2 2/3 = 8/3 cups
for 2 1/2 = 5/2 pancake = 8/3 * 5/2 = 40/6 cups = 6 4/6 cups
