Diameter of each hemispheral holes = the diameter of a full sphere = side length of cube = 2 units.
<h3>What is a Hemisphere?</h3>
A hemishpere is half of a sphere. Thus, two hemispheres makes one full sphere.
Given the image as shown below, since the identical hemispheral holes are centered at the center of each fce and they touch each other at only one point, it means that two hemisphere meet to make one full sphere.
Therefore, the diameter of a full sphere = side length of cube.
Thus, diameter of each hemispheral holes = the diameter of a full sphere = side length of cube = 2 units.

Answer:
1.5 inches/ week
Step-by-step explanation
Given
Height of he plant = 3in
If the plant grows by 2in every week
The rate of change = Height of plant/weekly increase
The rate of change = 3/2 = 1.5 inches/ week
Answer:
<em>Scott will take 221 minutes to run 52 km</em>
Step-by-step explanation:
<u>Speed</u>
The speed of an object can be calculated with the formula:
Where d is the distance traveled and t is the time taken.
Scott can run d=20 km in 85 minutes. Thus, his speed is:
Now he wants to know how many minutes it will take him to run d=52 km. Solving the formula for t:
Since the speed has been already determined:
Multiplying by the reciprocal of the denominator:
t = 221 min
Scott will take 221 minutes to run 52 km
