390
Step-by-step explanation:
v=(4/3)pi x r cubed. r= 1/2 diameter.
33.5x(4/3) pi cubed =radius. = 779.03270%2=389.51 about 390.
sorry if I'm wrong did it in my head.
I think it would be y=2(4x+200)
2 being it doubled and x would be to insert the twelve in to solve, and you add the 200 bacteria you already have.
Answer:
length of rectangle = 32.25 cm
Width of rectangle = 10.75 cm
Step-by-step explanation:
Let the length of rectangle be x.
And width of rectangle be y.
According to the problem,
x = 3y {Since the length of a rectangle is equal to triple the width}
Also,
Perimeter of rectangle = 86
or 2 (x + y) = 86
Plug x =3y in the above equation
We get, 2(3y + y) = 86
2 * 4y = 86
4y = 43
y = 43/4 = 10.75
So, length of rectangle = 3 * 10.75 = 32.25cm
Width of rectangle = 10.75cm
For 100kg
15% : (100-x)0.15
75% : 0.75x
equation
(100-x)0.15 + 0.75x = 100*0.63
solve for x:
x = 80kg of 75%
20kg of 15%
