Answer: No, the ratios 11/15 and 1/6 do not form a proportion.
Explanation: Proportion says that two ratios (or fractions) are equal.
Example:
Proportion 1/3 : 2/6
So 1-out-of-3 is equal to 2-out-of-6
The ratios are the same, so they are in proportion.
If I multiplied 1 by 11 and then 6 by 11, I would get 11/66, therefore 11/15 and 1/6 do not form a proportion.
Answer:
6.75cm
Step-by-step explanation:
The straw fits diagonally inside the can so it makes a right angled triangle with height and base of the can ( which is the diameter of the can)
So, hypotenuse = length of straw = 22.5cm
perpendicular = 18cm
base = diameter of can(d)
Using pythagoras theorem
h² = p² + b²
(22.5)² = 18² + d²
506.25 = 324 + d²
d² = 506.25 - 324
d² = 182.25
d = 13.5cm
Now radius = d/2 = 13.5/2 = 6.75cm

Answer:
12/5
Step-by-step explanation:
The tangent ratio is the ratio of the opposite side (GH) to the adjacent side (FG). The mnemonic SOH CAH TOA can help you remember this:
Tan = Opposite/Adjacent
In this triangle, ...
tan(F) = GH/FG = 12/5
