Answer:
A:-4
Step-by-step explanation:
If you simplify 9(2x+1)<9x-18 you will get 9x<-27. That will mean x<-3 and the only answer for something less than -3 is -4.
If the answer was right, please put 5 stars.
The answer is c. 2 hours and 45 minutes
Answer:
-17/10 as a simplified fraction or -1 7/10 as a normal fraction
Step-by-step explanation:
This is the concept of scale factors, given that the length of the model which has been modeled by scale factor 1/64 is 0.39 inches, then the actual diameter will be:
scale scale factor=(model diameter)/(actual diameter)
where:
actual diameter=(model diameter)/(scale factor)
=0.39/(1/64)
=24.96 inches
Short answer 3 times as much = 54 m^3 <<<<< answer
The volumes are krelated by k So solve for k
Volume of Cylinder = k Volume of the cone.
pi r^2 h = k(1/3 pi r^2 h) Since you know that r is the same in both and so is h they divide out.
divide by h
pi r^2 = k (1/3 pi r^2 Divide by pi
r^2 = k (1/3 r^2 ) Divide by r^2
1 = k (1/3) multiply by 3
3 = k
The volume will be 3 times as much.as the cone.
3 * 18 = volume of cylinder.
54 <<<< volume of cylinder.
