Q1)
11 * 260 / 4 = 715
answer
715 p
Q2)
15 * 130 / 10 = 195
answer
195 <span>€</span>
135, 140, 145, 150, 155, 160, 165, 170, 175. The pattern is +5.
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.

Answer: 3.5</h3>
=========================================
Explanation:
Start by sorting the values from smallest to largest. This is known as ascending order. The original set {3, 5, 7, 4, 3, 1} will sort to {1, 3, 3, 4, 5, 7}
After the values are sorted, we will look at the middle most value to find the median. Because there are six items in this data set, the median number is between slot 3 and slot 4. Note how the sorted data set breaks down into
{1, 3, 3} and {4, 5, 7}
we see that 3 and 4 are tied for the middle most, so the median must be 3.5 which is halfway between 3 and 4.
