d = 2(4 + c)
adding 4 and c, which is the sum, and multiplying that by 2 will give us d.
The car is travelling at 90 kilometers per hour (90 kmph)
What is the car's speed in kilometers per minute?)
We know 1 hour = 60 minutes,
90 km / 60 minutes = 1.5 kilometers per minute
<em>The speed of the car is 1.5 kilometers per minute
</em>
How many kilometers will the car travel in 15 minutes?)
We know that the car travels 1.5 kilometers in 1 minute. So in 15 minutes:
1.5 kilometers * 15 minutes = 22.5 kilometers
The car will travel 22.5 kilometers in 15 minutes.

Answer:
Step-by-step explanation:
A. 0.36 g/cm³
Explanation:
Density = mass/volume
We know the mass, but we must calculate the volume.
The formula for the <em>volume of a sphere</em> is
V = ⁴/₃πr³
r = 2 cm
V = ⁴/₃π × 2³
V = (4π×8)/3
V = (32π)/3
V = 33.5 cm³
=====
Calculate the <em>density
</em>
Density = 12/33.5
Density = 0.36 g/cm³
The density of the sphere is 0.36 g/cm³.
