Assume you have sea water that weighs 64 lb/ft³ and contains 35 parts per thousand (0.0035) dissolved salt by weight. How many c

zlopas [31]

Answer:

558.036 lb

Step-by-step explanation:

Let x is the amount of the sea water to collect 125 lb of sea salt

As given: 64 lb/ft³ has 0.0035 dissolved salt by weight

So the formula to find out the amount of the sea water is:

64 lb/ft³ * 0.0035 *x ft³ = 125 lb

<=> x = $\frac{125}{64*0.035}$ = 558.036 lb

Hope it will find you well.

Find the Circumference of a circle with a Diameter of 9 inches Group of answer choices 9 pi inches 9 pi inches^2 9 pi inches^3 1

katen-ka-za [31]

Answer: $9\pi\ in.$

Step-by-step explanation:

Given

The diameter of a circle is $d=9\ in.$

So, the radius is $r=\frac{d}{2}=4.5\ in.$

The circumference is given by $2\pi r$

Insert the values

$\Rightarrow 2\pi \cdot 4.5\\\Rightarrow 9\pi \ in.$

Thus, the circumference of the circle is $9\pi\ in.$
