Answer: False
Explanation: The plate tectonics move due to convection currents of the mantle; the cooler upper mantle descends while the hotter lower mantles ascend. The heat that drives these convection currents emanated from the core of the earth (not the sun).
Multiply first and then divide
Answer: see below
<u>Explanation:</u>
When multiplying or dividing, use the smallest number of significant figures (sf) of the digits provided.
37(a) 24 × 3.26 = 78.24 <em>2 sf × 3 sf </em>--> round to 2 sf's
≈ 78
(b) 120 × 0.10 = 12 <em>2 sf × 2 sf </em>--> round to 2 sf's
= 12
(c) 1.23 × 2.0 = 2.46 <em>3 sf × 2 sf </em>--> round to 2 sf's
= 2.5
(d) 53 × 1.53 = 81.09 <em>2 sf × 3 sf </em>--> round to 2 sf's
= 81
38(a) 4.84 ÷ 2.4 = 2.0167 <em>3 sf × 2 sf </em>--> round to 2 sf's
= 2.0
(b) 60.2 ÷ 20.1 = 2.995 <em>3 sf × 3 sf </em>--> round to 3 sf's
= 3.00
(c) 102.4 ÷ 51.2 = 2 <em>4 sf × 3 sf </em>--> round to 3 sf's
= 2.00
(d) 168 ÷ 58 = 2.896 <em>3 sf × 2 sf </em>--> round to 2 sf's
= 2.9
Answer:
A suggested solution for an unexplained occurrence.
Explanation:
A hypothesis is an educated guess, because you don't know what will happen / what is going to happen, you are just making a guess on what you think will happen. It is a solution for an unexplained occurrence.
