12.48 milliliters of medicine were separated into doses of 4 mL each. how many doses were made?
ivolga24 [154]

The number of doses are \boxed{\bf3}, if each dose quantity is 4 mL and total medicine is 12.48 mL.

Further explanation:

The total quantity of the medicine in millilitres is 12.48.

The quantity of one dose in millilitres is 4.

To find the number of doses possible from 12.48 millilitres quantity of medicine with each doses has 4 millilitres quantity is calculated by the use of division.

Here, dividend is the quantity of all medicine and divisor is the quantity of each doses.

Substitute, number 12.48 for dividend and number 4 for divisor then obtain the quotient by the use of division as shown below.

\begin{aligned}4\mathop{\left){\vphantom{1{12.48}}}\right.\!\!\!\!\overline{\,\,\,\vphantom 1{{12.48}}}}\limits^{\displaystyle\hfill\,\,\, {3.12}} \hfill\\\,\,\,\,\,\,\underline{12 \downarrow }\hfill\\\,\,\,\,\,\,\,\,\,04\hfill\\\,\,\,\,\,\,\,\,\,\,\,\,\underline{4\downarrow } \hfill\\\,\,\,\,\,\,\,\,\,\,\,\,08\hfill\\\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\underline8\hfill\\\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,0\hfill\\\end{aligned}

The quotient of the above division is 3.12.

The number of doses is always being in natural number.

It is observed that nearest natural number for 3.12 is 3.

Thus, the number of doses are \boxed{\bf3}, if each dose quantity is 4 mL and total medicine is 12.48 ml.

Thats my question down there mates
Law Incorporation [45]

Answer:

x = 9

Step-by-step explanation:

A line segment parallel to a side of a triangle and intersecting the other 2 sides divides the 2 sides in proportion, that is

\frac{9}{72} = \frac{1}{8} = \frac{3x-20}{56} ( cross-  multiply )

8(3x - 20) = 56

24x - 160 = 56 ( add 160 to both sides )

24x = 216 ( divide both sides by 24 )

x = 9

Vesna [10]

Answer:

\frac{x^2}{9} - 4x + 36

Step-by-step explanation:

(\frac{x}{3} - 6)² = (\frac{x}{3} - 6)(\frac{x}{3} - 6)

Each term in the second factor is multiplied by each term in the firs t factor, that is

\frac{x}{3}(\frac{x}{3} - 6) - 6(\frac{x}{3} - 6)

Distribute both parenthesis

= \frac{x^2}{9} - 2x - 2x + 36 ← collect like terms

= \frac{x^2}{9} - 4x + 36
