If a term is multiplied by zero, the result product will always be
Serga [27]
Hi there!

If any term, no matter what the number multiplied by zero will always turn out to be zero. I can give you an example of why this is correct.

We'll use apples. :P

If we have four apples multiplied by zero, you'd have zero apple because there's NO groups of apples to use.

Two times three is six because there are two groups of three, or three groups of two. But since earlier we said that there were zero groups of apples, there is zero groups of four so that cancels out to make none.

Hope this helps! :D

The number of taxi accidents is approximated by y=−143.3x2+1823.3x+6820 and the number of injuries is approximated by y=−416.72x
antiseptic1488 [7]

To get for the taxi accidents in 1998, we must note that x = 8. Therefore using the equation y=−143.3x2+1823.3x+6820 , we can calculate for the number of taxi accidents.

y = -143.3 * (8)^2 + 1823.3 * 8 + 6820

y = 12,235.2

There were about 12,235 taxi accidents in 1998.

Kim knows she should keep her fat intake to less than 130 grams per day if on a 4,000 calorie diet. She is on a 1,500 calorie pe
evablogger [386]
130/4000 = 13/400

13/400 = 0.0325

= 3.25%

Soo.. 3.25% of 1500 is your answer 

This is how I find percentages..
10% of 1500 = 150
So 5% of 1500 = 75
So 2.5% of 1500 = 37.5

since you are looking for 3.25%, find an answer in between 37.5 and 75, eliminating all answers but C.

The answer is C = 48.7567 grams
