Answer:
D) 81x²y¹⁰
Step-by-step explanation:
(9xy⁵)²
Because all of 9xy⁵ are in the parentheses, each component is raised to the 2nd degree.
(9)² = 81
(x)² = x²
(y⁵)² = y¹⁰ -- When you raise an exponent to another exponent, you multiply the exponents.
Now combine the components.
D) 81x²y¹⁰
3 - 1/8a = 1/4
The goal is to isolate "a" and its coefficient to make the simplification process easier.
Start by subtracting 3 from both sides:
3 - 3 - 1/8a = 1/4 -3
-1/8a = 1/4 - 3
Next, multiply 3 by 4/4 to convert it into a fraction:
-1/8a = 1/4 - [3 • (4/4)]
-1/8a = 1/4 - 12/4
-1/8a = - 11/4
Multiply both sides by -8:
(-8) -1/8a = - 11/4 (-8)
a = 88/4 = 22
Therefore, a = 22.
Answer:
51
Step-by-step explanation:
Plug in 3 as x into the function:
g(x) = 9x + 24
g(3) = 9(3) + 24
g(3) = 27 + 24
g(3) = 51
Do you mean the #12 and severe to fifths to a decimals if you are then it's 12.57
Answer:
P (not drawing a black marble) = 4/5
P (red marble) = 3/10
Step-by-step explanation:
The total number of marbles is
5 blue marbles +2 black marbles+ 3 red marbles = 10 marbles
P (not drawing a black marble) =
The marbles that are not black/ total marbles
(blue + red)/ total
(5+3)/10
8/10
4/5
P (red marble) = red marble/ total
= 3/10
