After both investigations, the new resulting substances were left undisturbed for 24 hours before recording their properties. Using the information provided in the table above, choose three correct answers. A chemical change took place during investigation A
A chemical change took place during investigation B
Temperature change, bubbling, change in color, and producing a sound are all signs of a chemical change.
Substance 1 and 2 did not result in a chemical change
The substances present after investigation A have the same molecules as the original substances.
The substances present after investigation B have the same molecules as the original substances.

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²

part a: 1.08

part b: 27.59
