Answer:
Step-by-step explanation:
step 1
Calculate the volume of the cylinder (flower vase)
The volume is equal to
we have
-----> the radius is half the diameter
substitute the values
------> exact value
step 2
Calculate 2/3 of the volume
21(2-x)+12x=44 21x2=42 21x-x=21x
42-21x+12x=44 -21x + 12x= -9x
42-9x=44
-42 -42
9x=2 9x/9=x 2/9=4.5
x=4.5
Answer:
-2
Step-by-step explanation:
-4x^3 = 32
x^3 = -8
take the cube root of both sides.
x = -2
65
since p=25
40+25= 65

290.
We know that the hundreds is two already.
The tens digit is 9 more than the ones digit, but since a digit can't be more than 9, the ones must be 0.
So the tens is 9 and the ones place is 0. Hopes this helps :)
