A1 On which surface of the leaf did most bubbles appear?
A2 The bubbles contained gas that came out from inside the leaf.
Which part of the leaf do you think the gas came from? (Look at
the diagram of the inside of the leaf above.)
A3
Suggest how the gas got out of the leaf.
A4
Use what you know about the effect of heat on gases to explain why
the gases came out of the leaf when it was put into warm water.

one side of a triangle is 8cm and the angles on it's ends are 35° and 65°.Find the area of the triangle.(sin = 0.57°,sin 65° = .91,sin 80° = 0.98)65°.Find

a = p(1 + rt) . . account balance after time t at rate r starting with principal p

3000 = 2500(1 + 0.0202t) . . filling in the given numbers

1.2 = 1 + 0.0202t . . divide by 2500

0.2 = 0.0202t . . . subtract 1

0.2/0.0202 = t ≈ 9.901

it will take about 9.9 years for the account balance to reach $3000.

true, i don't really know what you're asking but from the info you provided im guessing the answer is true.
