T = kh where t = tons and h = hours, k is the constant of variation
This is direct variation.
27 = k*3
= 27/3 = 9
Equation of variation is t = 9h
Amount produced in 8 hours t = 9*8 = 72 tons Answer
Answer:
27
Step-by-step explanation:
If a= -3 what is 3a^2 = 27
I think the answer should be 6,I just added the two fractions
Answer:
9 sides
Step-by-step explanation:
exterior angle + interior angle = 180° , so
exterior angle + 140° = 180° ( subtract 140° from both sides )
exterior angle = 40°
The sum of the exterior angles of a polygon = 360°
Dividing sum by the measure of 1 exterior angles gives number of sides
number of sides =
= 9
