A wooden board in the shape of a rectangular prism measures 0.3 mile by 2.1 miles by 0.1 mile and has a mass of 0.07 kilogram. W

Maslowich

The definition of density is given by:
D = m / V
Where,
m: mass
V: volume
The volume of the rectangular prism is given by:
V = (0.3) * (2.1) * (0.1)
V = 0.063 mi ^ 3
Substituting the values:
D = 0.07 / 0.063
D = 1.111111111 Kg / mi ^ 3
Round to the nearest tenth:
D = 1.1 Kg / mi ^ 3
Answer:
the density of the board is:
D = 1.1 Kg / mi ^ 3

Answer: hope it helps

Step-by-step explanation:The balloon will not reach 2,500 feet after 4 minutes.

Step-by-step explanation:

The equation of the line in the point-slope form is

A hot air balloon in flight begins to ascend at a steady rate of 120 feet per minute, then the slope is

After minutes, the balloon is at an altitude of feet. This means, the line passes through the point (1.5, 2,150).

Substitute the slope and point coordinates into the equation:

We know that after 3 minutes, the balloon is at an altitude of 2,330 feet. Check this:

Now, find the height after 4 minutes:

Thus, the balloon will reach only 2,450 feet after 4 minutes.
