Answer:
1 or 5
Step-by-step explanation:
A coefficient is "a numerical or constant quantity placed before and multiplying the variable in an algebraic expression (e.g. 4 in 4xy)".
So, in this case, the coefficient of 5x would be 5.
The coefficient of x^2 would be 1.
Hope this helps!
Answer: option A) 1/3
Justification:
1) The probability that a point chosen at random <span>in the regular hexagon lies in the shaded region is equal to:
area of the shaded region
---------------------------------------
area of the hexagon
2) The hexagon is formed by 6 equal triangles and the shaded area is formed by 2 of those triangles.
3) Therefor,naming x the area of one triangle, the the above fraction is equal to:
area of two triangles 2x
------------------------------- = -------- = 2/6 = 1/3
area of six triangles 6x
And that is the answer: 1/3

Answer: -4</h3>
Explanation:
Move the decimal point to the right one spot for each value
-3.2 turns into -32
0.8 turns into 8.0 which is the same as 8
That means the given fraction is the same as -32/8 which simplifies into -4
Answer:
(125/6)π units³
Step-by-step explanation:
The formula for the surface area of a sphere is A = 4πr². Solving this for r² yields:
A
r² = ------
4π
and in this case r² is:
25π
r² = ---------, or 25/4 units²
4π
Thus, the radius, r, is 5/2 units.
The volume of a sphere of radius r is V = (4/3)πr³ units³
Here, that volume is V = (4/3)π(5/2)³ units³
4π 125 units³
= ------ · ------------------ = (125/6)π units³

Answer: -4860y^2
Solution:
81 x (5y x 6) x (-2y)
-81 x 5y x 6 x 2y
= -4860y^2
