Step-by-step explanation:
given that V is directly proportional to u and inversely proportional to f , then the equation relating them is
V =
← k is the constant of proportion
(a)
to find k use the condition when u = 1 and f = 3 , V =
, then
=
( cross- multiply )
6k = 3 ( divide both sides by 6 )
k =
= 
V =
← equation of proportion
(b)
when f = 4 and V = 1
=
, then
=
=
( cross- multiply )
4u = 40 ( divide both sides by 4 )
u = 10
Answer:
<h2>20 ft, 48 ft, 52 ft</h2>
Step-by-step explanation:
The side lengths of ΔEFG are:
5 ft, 12 ft and 13 ft.
The scale factor: s = 4
All sides of the ΔKLM are four times longer than the sides of the ΔKLM.
Therefore the side lengths of KLM are:
5 ft · 4 = 20 ft
12 ft · 4 = 48 ft
13 ft · 4 = 52 ft
45.6%, I think
If the angle was 45 degrees, then 50% of the circumference of the ice cream would be inside the cone.
But the real angle is 41. 41 = (41/45) * 45
So if we multiply 45 by 41/45, we get 41. In the same way, if multiply the "50%" by 41/45, we get the percentage of ice cream circumference that is in the cone.
50% * 41/45 = 45.6%
