The time, T (seconds), it takes for a pot of water to boil is proportional to the amount, A (litres), of water. It takes 140 seconds to boil 2.5 litres of water.
Work out how long it takes (to the nearest second) to boil 1.8 litres.

answer: r there any options?

step-by-step explanation:

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
