Answer:
678.24 ft³
Step-by-step explanation:
The larger cone has linear dimensions (radius and height) that are 3 times those of the smaller cone. (ratio = 6 ft/(2 ft) = 3)
The ratio of volumes is the cube of the ratio of linear dimensions, so the volume of the larger cone is ...
... V = (25.12 ft³)·(3³) = (25.12 × 27) ft³ = 678.24 ft³
Answer:
Let's denote:
The cost of buying 1 burger: x
The cost of buying 1 drink: y
Then, we have:
5x + 3y = 13 (1)
3x + 5y = 11 (2)
Add up both sides of (1) and (2):
=> 8x + 8y = 24
=> x + y =3 (*)
Subtract both sides of (1) to (2):
2x - 2y = 2
=> x - y = 1 (**)
From (*) and (**):
x = 2
y = 1
=> The cost of buying 2 burgers and 2 drinks: 2(x + y) = 2(2 + 1) = 6$
Answer:
u can use formula whole root ,( x2-x1)²+(y2-y1)²
hope it helps...
Subst. 1/4 for x in f(x) = x^2 + 2: f(1/4) = (1/4)^2 + 2 = 1/16 + 2 = 2 1/16
This is the range when the domain is 1/4. Usually a domain contains more than one number.
