Every day about 140, 000, 000 plastic water bottles are brought in the United States each bottle is about 0.25 m long in the equator of the earth is about 40, 000, 000 m around how many times can the earth equator be circle by a line of plastic bottles used in the United States every day

Answers

Facts:
Bottles sold daily: 140 million
Each bottle: ~0.25 meters
Equator : 40 million meters

140 mil. Bottles * 0,25 m = 35 million meters

35<40 ( equator) which means you can't circle it not even once with the bottles sold in US in one day!

So 40:35= 0,875

That means we can circle only 87.5% of the Equator!

Info: you need 160 million bottles to circle the Equator once.

Write an algebraic expression to represent the verbal expression the difference between the product of 4 and a number and the square of the number

Answers

You set it up like this.

It says "the difference", so you put a minus sign: -
It says that the minuend, or the part being taken away from is a quantity equal to the product of 4 and "some number" (we'll use x), so now you have: (4 * x) -
Next, it says the subtrahend, or part being removed, is the square of "the number", meaning we use the "some number", x, from before, so now you have: (4 * x) - x^2
