A pharmacist is filling small empty bottles with cough syrup from a larger bottle. He can solve the inequality to find the numbe
sammy [17]

Answer:

1000 -25x >250.

Step-by-step explanation:

Let us assume the capacity of a large bottle = 1000 ml.

And the capacity of each small bottle = 25 ml.

Reaming milliliters in large bottles = 250 milliliters.

Number of bottles = x bottles.

The total capacity of the large bottle - capacity of a small bottle × number of bottles > Remaining milliliters in a large bottle.

Therefore, we can set up an inequality.

1000 - 25 × x > 250.

1000 -25x >250.

Find the area of an equilateral triangle with radius 5√3 m. Leave your answer in simplest radical form.
nevsk [136]
In an equilateral triangle the radius of inscribed circle is equal to
r= \frac{a \sqrt{3} }{6}, so 
5 \sqrt{3} = \frac{a \sqrt{3} }{6} and 
a=30.
The area of this equilateral triangle is A= \frac{a^2 \sqrt{3} }{4} =\frac{30^2\cdot \sqrt{3} }{4}=225 \sqrt{3} square units.
