Answer:
x3r9
Step-by-step explanation:
Vcylinder = πr2h
After plugging everything in you should get (3.14)(3.9)(30) this simplifies should get you 367.38m^3. Hope this helps!
-2(m + 4) = 40
The first step is to use the distributive property to clear the parenthesis
-2 * m + -2* 4 = 40
-2m - 8 = 40
next, to isolate the variable, add 8 to both sides
-2m - 8 + 8 = 40 + 8
-2m = 48
the last step is to get rid of the multiplication by -2 we will divide by -2
(-2m)/-2 = 48/-2
m = -24
Answer:
C
Step-by-step explanation:
You need to multiply the variable by how much each ride costs.
Answer:
x = 81
Step-by-step explanation:
y = k√x
56 = k√49
56 = k(7)
Divide both sides by 7
8 = k
k = 8
------------------------
When y = 72
72 = 8√x
Divide both sides by 8
9 = √x
Square both sides
81 = x
x = 81
