Two similar cones have radii in the ratio n:m. What is the ratio of their slant heights?
denis-greek [22]

Answer:

The ratio of the slant heights of the two cones will also be n : m.

Step-by-step explanation:

See the attached diagram.

If we take the vertical sections along any diameter of the base circle of the cones A and B then the triangular sections as we get will be similar.

Now, ratio of the base of the triangles A and B i.e. the ratio of the diameters of the cones A and B will be 2n : 2m = n : m and this will be the same as the ratios of other two sides of the triangles A and B.

Therefore, the ratio of the slant heights of the two cones will also be n : m. (Answer)

If it takes 3 men 5 hours to dig 12 holes, how many hours does it take for 3 men to dig 84 holes?
alexgriva [62]

Answer:

Hence it will take 35hours

Step-by-step explanation:

Let the time it took to dig hole be x

Ley the number of holes be n

Using the relationship x = kn (direct relationship)

if it takes 3 men 5 hours to dig 12 holes, hence;

when x = 5, n = 12

k = x/n

k = 5/12

To get how many hours it take for 3 men to dig 84 holes, then;

when n = 84, x = ?

x = 5/12 * 84

x = 5 * 7

x = 35hours

Hence it will take 35hours

Elina [12.6K]

Answer:

  always true

Step-by-step explanation:

Last year, a factory produced 126 widgets per day. After retooling, production increased to 189 widgets per day. What was the pe
lys-0071 [83]
<h3>Answer:   50%</h3>

Work Shown:

change = new - old = 189-126 = 63

percent increase = (change/old)*100%

percent increase = (63/126)*100%

percent increase = (0.50)*100%

percent increase = 50%

50% of 126 = 0.50*126 = 63

126+63 = 189

The answer is confirmed.
