The question is incomplete, the complete question is;
The radius of the sphere is 10 units.What is the approximate volume of the sphere? Use π = 3.14 and round to the nearest whole cubic unit. cubic units
Answer:
4187 cubic units
Step-by-step explanation:
According to the question;
radius (r) = 10 units
π = 3.14
Volume of a sphere = 4/3*π*r^3
Substituting values;
V = 4/3*(3.14)*(10)^3
V = 4186.67 cubic units
V = 4187 cubic units (To the nearest whole cubic unit)
<span>(-2/3)*(w-(4/9)) = -4/3 // + -4/3
(-2/3)*(w-(4/9))-(-4/3) = 0
(-2/3)*(w-4/9)+4/3 = 0
4/3-2/3*(w-4/9) = 0
(-2/3*3*(w-4/9))/3+4/3 = 0
4-2/3*3*(w-4/9) = 0
44/9-2*w = 0
(44/9-2*w)/3 = 0
(44/9-2*w)/3 = 0 // * 3
44/9-2*w = 0
44/9-2*w = 0 // - 44/9
-2*w = -44/9 // : -2
w = -44/9/(-2)
w = 22/9
w = 22/9</span>
Answer:
A)
Step-by-step explanation:
You just basically substitute the coordinates into the equation
2x+3y =6
2(0) +3y =6
y=2
Answer:
y = 1
x = -2
Step-by-step explanation:
During the substitution method, you are substituting one function into another. Because both functions are set equal to "x", you can make the functions equal each other. This allows you to 'get rid' of the "x" variable and simplify to find the value of "y".
5A) x = -2y
5B) x = 2 - 4y
-2y = 2 - 4y <----- Set both equations equal
2y = 2 <----- Add 4y to both sides
y = 1 <----- Divide both sides by 2
Now that you know what "y" equals, you can plug that value into the "y" variable into one of the equations. This will allow you to then simplify and find the answer for "x".
x = -2y <----- Equation 5A
x = -2(1) <----- Plug 1 into "y"
x = -2 <----- Multiply -2 and 1
Answer:20
Step-by-step explanation:
1) You add (6+4) and should get 10
Then u will multiply 10 and 2 which is 20
