Answer:
750 ft^3
Step-by-step explanation:
Given that the cones are similar, the first step would be to determine their linear scale factor; That is the ratio of their radii;
The next step is to determine the volume scale factors. Since the linear scale factor is 2.5, the volume scale factor would be;
volume scale factor = (linear scale factor)^3
= 2.5^3 = 125/8
The volume of Cone B will thus be;
volume of Cone A * volume scale factor = 48 * 125/8 = 750 ft^3
<u>Answer:</u>
Jacara and Jurnee have $ 710000 and $ 390000 respectively as amounts.
<u>Step-by-step explanation:</u>
Let, Jacara's and Jurnee's amounts be $ x and $ y respectively.
According to the question,
20 % of the total amount = $ 220,000
So, total amount = $
=$ 1100,000
According to the question,
x + y = 1100,000 -----------(1)
and, x = -----------(2)
from (1), x = 1100,000 - y--------------(3)
Deducting (2) from (3),
⇒ y =
⇒ y = 390000-------------------(4)
from (1) and (4),
x = 1100,000 - 390000
= 710000---------------(5)
