Answer:
30
Step-by-step explanation:
Solution set: t>-11/3
A
Use distributive property:
7t-21>4t-32
Then solve for t:
3t>-11
t>-11/3
This is your solution set!

Higher
Order Thinking problems require you to think about the facts that are
given to you in any problem and do something with those facts. This
involves understanding them, infer from them, connect them to other
facts and concepts, categorize them, manipulate them, put them
together and apply them to find new solutions.

For
example the first problem which asks to evaluate the expression
0.1(3.7). This can also mean that 1/10*3.7 = 0.37.

Answer:
80cm3
Step-by-step explanation:
<span>The pressure, P, of a gas, varies inversely with its volume, V
</span>
∴ PV = k where k is constant
<span>The pressure is 84 Pa at a volume of 36 L.
</span>
<span>∴ at P = 84 ⇒⇒⇒ V = 36
</span>
<span>∴ K = PV = 84 * 36 = 3,024 ⇒⇒(1)</span>
If the volume is expanded to 216 L, what will the new pressure be?
We need to find P at V = 216
From the equation (1) ⇒⇒⇒ PV = 3024
substitute with V = 216
∴ 216 P = 3024
∴ P = 3024/216 = 14
The correct answer is option <span>B. 14 Pa</span>
