No because the cost to ship a video game starts at 4.85 but if it were to start at zero than I would because it consistently adds 39.99.
Answer:
8 years.
Step-by-step explanation:
Mara is 6.
6+8=14
Alberto is 20.
20+8=28
14*2=28.
In 8 years, Alberto will be twice Mara's age.

The volume of a cone can be found as:
Given the radius and height, we can find the volume of the cone:
The volume of a sphere is:
So, for each gum ball the volume is:
Therefore, the he closest approximation of the volume of the cone that can be filled with flavored ice is:
Conclusion: The volume of the cone that can be filled with flavored ice is 4.43 cubic inches.
-3x + y = 4
Solve for y
y = 3x + 4
Plug this y value into the other equation.
-9x + 5y = -1
-9x + 5(3x + 4) = -1
Distribute 5(3x + 4)
-9x + 15x + 20 = -1
Subtract 20 from both sides
-9x + 15x + 20 - 20 = -1 - 20
-9x + 15x = -21
Combine like terms
6x = -21
Divide both sides by 6
6/6 x = -21/6
1x = -21/6
x = -7/2
x = -3.5 or -7/2
Plug this value into an equation to solve for y.
-3(-3.5) + y = 4
10.5 + y = 4
Subtract both sides by 10.5
10.5 - 10.5 + y = 4 - 10.5
y = -6.5
Check this answer by plugging the value of x into the other equation.
-9(-3.5) + 5y = -1
31.5 + 5y = -1
Subtract both sides by 31.5
31.5 - 31.5 + 5y = -1 - 31.5
5y = -32.5
Divide both sides by 5
y = -6.5 or -13/2
Therefore the solution is ( -3.5 , -6.5 )
Answer:
(a/2) ^4 or a^4/16
Step-by-step explanation:
(8a^-3)^-4/3
split into two parts
8^ -4/3 * (a^-3)^-4/3
using the power to the power rule we can multiply the exponents
8^(-4/3) *a^(-3*-4/3)
8^ (-4/3) * a^(4)
replace 8 with 2^3
(2^3)^(-4/3) * a^(4)
using the power to the power rule we can multiply the exponents
2^(3*-4/3) * a^(4)
2 ^ (-4) * a^4
the negative exponent means it goes in the denominator if it is in the numerator
a^4/2^4
make a fraction
(a/2) ^4
or a^2/16
