Answer:
The radius of the base of the small cone is 3 feet
Step-by-step explanation:
The question requires the determination of the radius of the smaller cone
Therefore, height of the larger cone = 10 feet
Base diameter of the larger cone = 10 feet
Height of horizontal plane of small plane above base of larger cone = 4 feet
Hence the height of the small cone = 6 feet
Therefore, by similar triangles, and tangents we have;
Where:
x = The diameter of the base of the small cone
Therefore;
The radius of the base of the small cone = half the diameter of the base of the small cone
∴ The radius of the base of the small cone = (6 feet)/2 = 3 feet.
Answer:
20 candles is 50 dollars
Step-by-step explanation:
set up a proportion. you know what 4 candles is. that's ten dollars.
4/10 = 20/x
x will be your placeholder for the cost, because we don't know how much 20 candles is. now, make sure everything is lined up, obviously it'll be different on here. I'll post a picture of the work at the bottom.
take 4 and cross multiply it to X. that's 4x. then you'll take 10 and multiply it by 20. mental math, that gives you 200. so, now you've got a one step equation of 4x=200.
take 4 divide it into 200, and you get 50. hope this helps!!
