The radii of two similar cylindrical jugs are in the ratio 3:7. Calculate the ratio of their volumes
1 : 04
3 : 07
9 : 49
0.086111111
27 : 343
Correct answer is E
radius ratio volume
r = \(r^3\)
so that
3 : 7 = \(3^3 : 7^3\) = 27 : 343
Simplify the expression: \(Log_{4}16\) + \(Log_{3}27\) + \(Log_{8}4096\)
-9
\(\frac{1}{3}\)
\(\frac{1}{9}\)
3
9
Correct answer is E
WHERE:
\(Log_{4}16\) = 2
\(Log_{3}27\) = 3
\(Log_{8}4096\) = 4
: 2 + 3 + 4 = 9

Given that x2 + y2 + k = 60 and x = \(\sqrt{10}\) when y = 4, find the value of k.
56
34
32
-34
-56
Correct answer is B
x\(^2\) + y\(^2\) + k = 60
(√10)\(^2\) + (4)\(^2\) + k = 60
k + 10 + 16 = 60
k = 60 - 26
k = 34
