One <em><u>possible counterexample</u></em> would be:

The city of Portland is in Connecticut.

Explanation:

A counterexample is something that proves a statement wrong.  Since the city of Portland is in multiple states (Oregon, Maine, Connecticut, Arkansas, etc.), any of the other states having a Portland would serve as a counterexample.

A conveyor belt carries supplies from the first floor to the second floor, which is 39 feet higher.
Murljashka [212]

The supplies travelled 45ft and it took 0.6min to get to the next floor.

<h3>What is trigonometry?</h3>

Trigonometry is the branch of mathematics dealing with the relationship between the sides of a triangle and the angles.

Analysis:

The supplies distance travelled, distance of first floor from second floor and the ground form a right angled triangle.

so that sin 60 = 39/distance travelled by supplies

distance travelled by supplies = 39/sin 60 = 39/0.866 = 45 feet.

speed = distance / time

time = distance / speed = 45/70 = 0.6 min

In conclusion, the distance and time time taken for the supplies to get to the next floor is 45feet and 0.6 min respectively.

A school raised &amp;4,589 in a sale. Mr Simmons class raised 1/100 of the money. How much did Mr Simmons class raise?
Ksenya-84 [330]

Alright, lets get started.

total amount school raised in sale = $ 4589

Mr Simmons class raised \frac{1}{100} of the money.

So, if we want to find amount of the money Mr. Simmons raised, we sould take one hundered of the total amount.

Hence money raised by Mr. Simmons class = \frac{1}{100} * 4589

Hence money raised by Mr. Simmons class = \frac{4589}{100}

Hence money raised by Mr. Simmons class = $ 45.89 : Answer

Hope it will help :)
