Answer:
The new volume is 1/343 of the old volume or the ratio of the new volume to the old volume is 1 to 343
Step-by-step explanation:
In this question, we are asked to state the effect of multiplying the radius of a sphere by 1/7 on the volume.
Mathematically, the volume of a sphere V can be calculated using the formula
V = 4/3 * π * r^3
Now multiplying the radius by 1/7, the new radius will be r/7
Thus the new volume here will be
V2 = 4/3 * π * (r/7)^3
V2 = 4/3 * π * (r^3)/343
Thus we can conclude that the value of the volume will be decreased by a factor of 343
Meaning the ratio of the old volume to the new volume will be 1 to 343
0.25-1.125-16/8=??
Answer is -2.875
980 square meters is the total
Answer: Total number of students will be 112.
Step-by-step explanation:
Since we have given that
The ratio of boys to girls in the top 10% of their class at Bixby High School was
So, Let the number of boys be 3x
Let the number of girls be 5x
According to question,
So, total number of students will be
Hence, Total number of students will be 112.
