Answer:
A compound inequality is an inequality that combines two simple inequalities. This article provides a review of how to graph and solve compound inequalities.
Step-by-step explanation:
I don't know how to answer the question, but I hope this helps.
Step-by-step explanation:
first of all, your teacher wrote nonsense in the answer options : an area is always given in squared units. never in cubed units (which would be volume).
the area is : 1/2 × perimeter × apothem
the perimeter is simply 12 × 5 = 60 meters.
apothem = (a/2)×cot(pi/12) = 5/2 × cot(pi/12) =
= 9.330127019... meters
so the area is
1/2 × 60 × 9.330127019... = 279.9038106... m²
therefore, the third answer option is correct (although it is m², and not m³).
by the way, you have question 3 wrong. I answered this with the correct apothem calculation in the explanation for question 4.
35 divided by 2.5 is 14, so she biked 14 miles in 1 hour. So 14*3= 42
She can bike 42 miles in 3 hours.
Answer:
a=1824
Step-by-step explanation:
Let the "other" angle be x. Then we can set up the equation: 2x + 60 + x = 180, because supplementary means that the angles add up to 180 degrees.
We get:
3x + 60 = 180
3x = 120
x = 40.
2(40) + 60 = 80 + 60 = 140.
So one angle is 140 degrees and the other angle is 40 degrees.
