To be able to arrange the volumes from least to greatest we must be mindful that the exponent of 10 in the scientific notation should be arranged from least to greatest also. If two or more items have the same exponents in the 10 of the scientific notation, we use the base for comparison. For this item, the arrangement should be
2.2x10^12 km³, 6.9x10^12 km³, 2.7x10^18 km³, and 4.9x10^21 km³
Thus, the answer to this item is letter B.
13. they are not, because the parentese's make it different by applying the order of operations to the two sections, rather than in a long line.
the first one is equal to 1/40 1/4 * 10 = 1/40
second one is equal to 3/8 10 / 40 / 2 *5 = .25 / 2 * 5 = 3/8
14. g + w = 40 since there are both grape and watermelon in the entire jar of 50
15. algebraic because it involves variables and not just numbers dependent on PEMDAS
<span>By definition, all sides of a regular polygon are equal in length. If you know the length of one of the sides, the area is given by the formula:
</span>
area=(s^2)n / 4 tan(180/n)
Area1=(14^2)5 / 4 tan(180/5) = 337.21 cm^2
Area2=(21^2)5 / 4 tan(180/5) = <span>758.73 cm^2
</span>
Therefore, the ratio of the area would be:
337.21 cm^2/758.73 cm^2 = 0.4444
Answer:
b
Step-by-step explanation:
The sum of angles 7 and 8 is 180, so to find angle 8 you would subtract angle 7 from 180. So:
180 - 92 = 88
The answer is B, 88 degrees.
