Density is a property of a material which describes the mass of a material per unit volume. It can be calculated by dividing the mass of the object with its volume. We calculate as follows:
Density = mass / volume = 400 / (8^3) = <span>0.78125 g/cm^3</span>
Answer: its 73,000

Answer:
Volume = 6048 
Step-by-step explanation:
Volume is the capacity of substance that a given measuring object can contain. It can be determined as;
Volume = length x width x height
In the given question, the refrigerator has an internal dimensions 18 inches, 14 inches and 24 inches.
The volume of the refrigerator can be determined as;
Volume = 24 x 14 x 18
= 6048
Volume = 6048
Thus, the internal volume of the refrigerator is 6048 cubic inches.
Answer:
x = 35°
Step-by-step explanation:
The question is as following
cos x = sin(20 + x)° and 0° < x < 90° , find X?
==============================================
cos x = sin(20 + x)°
sin and cos are co-functions,
which means that: cos x = cos [90 - (20 + x)]
∴ x = 70 - x
∴ 2x = 70
∴ x = 35°
======================
Note: cos θ = sin ( 90 - θ )
Step-by-step explanation:
0 degrees now
so 3 degrees an hour means
3 degrees : 1 hour ago
3×3= 9
so
9 degrees : 3 hours ago
3×4.5 =13.5
so
13.5 degrees : 4.5 hours ago
