The length of BC = 72
Solution:
Given ΔABC and ΔDEF are similar triangles.
ΔABC ΔDEF
AB = 54, BC = n, EF = 12, DE = 9
Similar triangle theorem:
If two triangles are similar then the corresponding sides are proportional to each other.
Substitute the given values, we get
Do cross multiplication.
Divide both sides of the equation by 9.
⇒ BC = 72
Option B is the correct answer.
The length of BC = 72.
Sally wants to buy some groceries. She wants to buy 2 kg of potatoes and 1 kg of onions. 1 kg of onions cost $5 but the paper that shows price of potatoes got lost. However, Sally remembers that few weeks ago she bought 3 kg of potatoes for $12. How much did Sally spent buying groceries?
Part 1:
First we need to find how much 1 kg of potatoes cost.
3*x = 12
x = 4
1 kg of potatoes cost $4
Part 2:
Now we need to find how much did she spent.
M = 4*2 + 1*5 = $13.

They teach the kids to group these. So the one spot, ten spot and hundred spot are called ONES PERIOD. The thousands, ten thousands and hundred thousands are grouped in THOUSANDS PERIOD. so in other words the number 208 would be a ONES PERIOD. Now let's say the number was 208,256 then 208 would be in the Thousands Period.
