Answer:
C. 5
> 15
Step-by-step explanation:
In the given series of inequalities, the inequality sign determines the final outcome.
A. 4 - 2 < 10
4 < 12
< 3
Since < 3, then the inequality is false
B. + 9 < 12
< 3
Since < 3, then the inequality is false
c. 5 > 15
> 3
Since > 3, then the inequality is true
D. 6 > 2
3 >
Since < 3, then the inequality is false
Thus, the only inequality that is true is option C.
Answer:
Option A. The volume of the sphere is multiplied by 1/343.
Step-by-step explanation:
The volume of a sphere can be obtained by the following formula:
V = 4/3πr^3
Let the initial volume (V1) of the sphere be:
V1 = 4/3πr^3 = (4πr^3)/3
Now, if we multiply the radius by 1/7, then the new volume (V2) of the sphere will be:
V2 = 4/3 x π x (1/7r)^3
V2 = 4/3 x π x 1/343r^3
V2 = (4πr^3)/1029
Now we determine the ratio of V2 : V1 as shown below:
V2/V1 = (4πr^3)/1029 ÷ (4πr^3)/3
V2/V1 = (4πr^3)/1029 × 3/(4πr^3)
V2/V1 = 3/1029
V2/V1 = 1/343
V2 = 1/343 x V1
Therefore, the volume of the sphere is multiplied by 1/343.
First you need to multiply the one in the bracket 7x2 which is 14 then u must multiply it with 3 to get the answer so 14x3 which equals to 42
