The correct answer is Sometimes
Answer:
Step-by-step explanation:
120cm^3
2b - 15 > 21
add 15 to both sides:
2b-15+15 > 21 + 15
2b > 36
Divide both sides by 2 :
2b/2 > 36/2
2b = 36
b = 36 / 2
b > 18
hope this helps!
Answer:
The approximate diameter of the larger tank is 8.10 meters
Step-by-step explanation:
Here, we want to calculate the diameter of the larger tank
The volume of a sphere
V = 4/3 * π * r^3
Let us calculate the volume of the standard model
That will be;
Since diameter is 6 and r = d/2
r = 6/2 = 3 meters
V = 4/3 * π * 3^3 = 36 π m^3
Now, the volume of the larger tank is 2.5 times of this;
The volume of the larger tank is 2.5 * 36 π = 90 π m^3
So we can calculate the radius of this before we calculate its diameter
4/3 * π * r^3 = 90 π
4r^3/3 = 90
r^3 = 270/4
r^3 = 67.5
r = 3x√(67.5)
r = 4.07 m
Diameter here is 2 times this
= 4.07 * 2 = 8.14
Answer:
k = -3636
Step-by-step explanation:
you subtract 425 from both sides, it cancels out on the left and adds more to the right
