Answer:
catastrophic
Step-by-step explanation:
Cuz it means "destructive"
Answer:
(8.99 x 10^9)(3 x 10^-5)(-6 x 10^-5)
(8.99 x 3)(10^9 x 10^-5)(-6 x 10^-5)
26.97 x 10^9-5(-6 x 10^-5)
26.97 x 10^4(-6 x 10^-5)
2.697 x 10^5(-6 x 10^-5)
-16.182
<h3>
Answer: Approximately -0.0742857 grams per year</h3>
======================================================
Work Shown:
x = year
y = amount of hydrocarbon emissions in grams, per mile driven
m = rate of change = slope
m = (y2 - y1)/(x2 - x1)
m = (0.8 - 3.4)/(2007 - 1972)
m = -2.6/35
m = -0.0742857 approximately
The approximate rate of change is about -0.0742857 grams per year. The negative rate of change indicates the per mile hydrocarbon amount has gone down by about 0.0742857 grams each year.
2/3 of its capacity - 60 * 2/3 gallons = 40 gallons.
Time to fill to 2/3 is 40 / 4/5 = 40 * 5 / 4
= 50 seconds (answer)
Answer:
x = 60°
Step-by-step explanation:
This is an equilateral triangle. All angles of this triangle are congruent and have a measure of 60°.
Other method.
We know: the sum of the measures of the angles of the triangle is equal to 180 °.
Therefore we have the equation:
x + x + x = 180°
3x = 180° <em>divide both sides by 3</em>
x = 60°
