Answer:
7 1/3 hours
Step-by-step explanation:
We are to assume that the total number of heater-hours required is a constant. That is, the time is inversely proportional to the number of heaters.
If the number of heaters goes up by a factor of 6/4 = 3/2, then the number of hours will go down by the inverse factor: 2/3.
With 6 heaters instead of 4, the time required is (2/3)(11 hours) = 7 1/3 hours.
Answer:
<h2>15.5 units</h2>
Step-by-step explanation:
This problem is on the mensuration of flat shapes, this time a square shape.
we know that the area of a square is given as
area= length*length
area= l^2
from the problem the area is given as
area= 240 units^2
substitute area for the area in the equation and then we solve for length we have
240= l^2
squareing both sides we have
√240= l
l= 15.49 units
to the nearest hundreths it is
15.5 units
I think the answer is 32 degrees but i am not 100% sure
