Answer:
320 cups of soup.
Step-by-step explanation:
Given:
A chef planning for a large banquet thinks that 2 out of every 5 dinner guests will order his soup appetizer.
He expects 800 guests at the banquet.
Question asked:
How many cups of soup he should prepare ?
Solution:
Ratio of soup appetizer to the number of guest = 2 : 5
Now, let number of cups of soup prepare for 800 guests =
Now, as we have to find through <u>equivalent ratios,</u> we can write it as:-
<em>2 : 5 = </em><em> : 800</em>
Thus, he should prepare 320 cups of soup for 800 guests.

u = 10.4 and v = 12
Solution:
In the given 2 sides of a triangle are 60°, 60°.
Sum of all the angles of a triangle = 180°
60° + 60° + third angle = 180°
⇒ third angle = 180° – 60° – 60°
⇒ third angle = 60°
All angles are equal, therefore the given triangle is an equilateral triangle.
⇒ All sides are equal in length.
⇒ v = 12
The line drawn from the top angle divides the triangle into two equal parts
and the line is perpendicular.
12 ÷ 2 = 6
Using Pythagoras theorem,
⇒
⇒
⇒
⇒
⇒ u = 10.4
Hence, u = 10.4 and v = 12.
