We have the following equation:
D = m / V
Where,
m: mass
V: volume
D: density.
The volume of the rectangular prism is:
V = (5) * (10) * (8)
V = 400 cm ^ 3
For Lead:
m = D * V
m = (11.36) * (400)
m = 4544 grams
For Iron:
m = D * V
m = (7.87) * (400)
m = 3148 grams
The difference of the masses is:
4544 - 3148 = 1396 grams
Answer:
The mass of the prism made of lead is 1396 grams than the one made of iron
Answer:
(A)Z(-3,-7)
Explanation:
The rotation of a point (x,y) by 180 degrees gives the point (-x,-y).
That is:
If the image point after rotation is (3,7), the coordinates of the pre-image will be:
The correct option is A.
Answer:
Step-by-step explanation:
A person selected by others to run for office is the nominee.
Let x represent the weight of a large box, and y represent the weight of a small box. The problem statement gives rise to two equations in these unknowns:
.. 12x +2y = 253
.. 3x +5y = 133
A graph shows these equations have solution
.. x = 18.5
.. y = 15.5
A large box weighs 18.5 kg.
A small box weighs 15.5 kg.
