Answer:
Step-by-step explanation:
<u>The volume of a cylinder:</u>
- V = πr²h, where r-radius, h-height
<u>New dimensions of the cake:</u>
<u>The volume of the bigger cake:</u>
- V1 = π*(2r)²*(3h) = 12*πr²h = 12V
- V1/V = 12
The ration of volumes is 12 : 1
Answer:
triangular prism
0.5 X 5 X 4 X 9 = 90 cubed cm
cuboid
6 X 5 X 20 = 600 cubed cm
triangular prism : cuboid
90:600
now simplify
both are divisible by 30
3:20
this cannot be simplified further
answer = 3:20
Okay. So, we're looking for the percentage of Celina's running speed as her walking speed. Her running sped is 8 mph and her walking speed is 4mph. All we have to do is 4/8 = x/100. You put change/original and x/100, because we're looking for the percent of change from running speed to walking speed. Cross multiply the values to get 400 = 8x. Divide each side by 8 to isolate the "x". 400/8 is 50. x = 50. Celina's walking speed is 50% of her running speed. The answer is B: 50%.
You can fit 15 2cm in a 600mm by 500mm.
(−2h+9)(9h−2)
-18h^2 + 4h + 81h - 18
Answer: -18h^2 + 85h - 18
