Answer:
117.8
Step-by-step explanation:
Surface area = πr²+πrl (whee r = radius and l = slant height)
= π×3²+π×3×9.5
= 75π/2
= 117.8
Answer:
(4^-3)(x^-3) y^(18)
or
y^18/ (64 x^3)
Step-by-step explanation:
(4xy^-6)^-3
Distribute the exponent to all terms in the parentheses
(4^-3)(x^-3) (y^-6)^-3
a^ b^c = a^ (b*c)
(4^-3)(x^-3) y^(-6*-3)
(4^-3)(x^-3) y^(18)
If we do not want negative exponents
a ^ -b = 1/ a^b
y^18/( 4^3 x^3)
y^18/ (64 x^3)
Answer:
Gaby scored 27 points.
Step-by-step explanation:
First, you have to find 3/5 of both of the numbers.
What I did was I found 1/5 of each number and multiplied it by 3.
25/5=5, so 1/5 of 25 is 5. 5(3)= 15, so Gaby scored 15 points in the first game.
20/5= 4, so 1/5 of 20 is 4. 4(3)= 12, so Gaby scored 12 points in the second game.
Finally, add 15+12, which equals 27 :).

Answer:
The value of n in the given equation is; n = 10
Step-by-step explanation:
Exponent for a natural power b is defined as iterated multiplication, which Knuth denoted by a single up-arrow:
a↑b = 
......[1]
Given the expression: 2↑2 * 2↑n = (2↑4)↑3
Using [1] in the given expression is;
Using 
and 
we have;
2 + n = 12 [ Using 
⇒ m =n ]
Subtract 2 to both sides of an equation:
2 + n - 2 = 12 -2
Simplify:
n = 10
Therefore, the value of n is, 10
