Answer:
Actual length of ship is 150 meters.
Step-by-step explanation:
As model ship is built to a scale of
1 centimeter : 5 meters and
length of model ship is 30 centimeters
Actual length of ship is 30
×
5
=
150 meters.
Answer:
J/K
Step-by-step explanation:
if PV = GcT, c = PV/GT
Substitute:
c = (N/m^2)(m^3)/K
c = (N*m)/K
We know that N*m = J, so c = J/k
Answer:
434,470 gallons
Step-by-step explanation:
The exponential equation for the volume v remaining after t hours can be written as ...
v(t) = (initial amount)×(decay factor)^(t/(decay time))
v(t) = 500,000×(1 -10%)^(t/3)
Then after 4 hours, the remaining volume is ...
v(4) = 500,000×(0.90^(4/3)) ≈ 434,470 . . . . gallons
_____
<em>Comment on the form of the equation</em>
The decay factor is related to the decay rate by ...
decay factor = 1 - (decay rate)
and the decay time is the time applicable to that decay rate. Here, the rate is 10% every 3 hours, so the decay time is 3 hours for a decay rate of 10%.
%error=100(estimated-actual)/actual
%error=100(96-(96-16))/(96-16)
%error=100(16/80)
%error=1600/80
%error=20%
She overestimated how many bracelets she would sell by 20%
Answer:
D. 6<x<24.
Step-by-step explanation:
Let x be the length of third side of our triangle.
We have been given that two sides of a triangle have lengths 9 and 15.
To find the possible length for 3rd side of our triangle we will use triangle inequality theorem.
Triangle inequality theorem states that the sum of the lengths of any two sides of a triangle should be greater than the length of the third side.
Using triangle inequality theorem we will get:
Therefore, the third side of triangle must be greater than 6 and less than 24 and option D is the correct choice.
