The answer to this is B. anthracite coal. Organic matter gradually turns into coal over many years of high pressure and temperature under the earth. The lowest form of coal is peat (where it is still recognizably plant matter), followed by lignite, then sub-bituminous coal, then bituminous coal, then anthracite. These are also ordered from lowest to highest composition of carbon.

After solving $|8-3p|\geq 2$ we get $p\geq \frac{10}{3}\,\, or\,\,p\leq 2$

So, Option A is correct.

Step-by-step explanation:

We need to solve the expression:

$|8-3p|\geq 2$

For solving, we apply the rule that:

if |u| ≥ a and a > 0 then, u ≤ -a and u ≥ a

Applying the rule:

$|8-3p|\geq 2\\8-3p\leq -2 \,\, and\,\,8-3p\geq 2\\$

$8-3p-8\leq -2-8 \,\, or\,\,8-3p-8\geq 2-8\\-3p\leq -10 \,\, or\,\,-3p\geq -6\\Multiply\,\,both\,\,sides\,\,by\,\,-1 (reverse\,\,the\,\,inequality\\3p\geq 10\,\, or\,\,3p\leq 6\\p\geq \frac{10}{3}\,\, or\,\,p\leq\frac{6}{3}\\p\geq\frac{10}{3}\,\, or\,\,p\leq 2$

After solving $|8-3p|\geq 2$ we get $p\geq \frac{10}{3}\,\, or\,\,p\leq 2$

So, Option A is correct.

a diver descends from an elevation of 6 feet below sea level to an elevation of 98 feet below sea level in 4 equal intervals. Wh

dangina [55]

98-6=92. This represents the amount of space he has to dive.
92/4=23. This represents your equal intervals.

So the answer is that the diver dove in equal intervals of 23 ft.
