There is a drug order for 75 mg of drug.The drug is available in 30-mg scored tablets. How many tablets should be administered?
rosijanka [135]

Answer:

Assuming that tablets can be devided, 2\frac{1}{2} tablets are needed.

Assuming that tablets cannot be devided, 3  tablets are needed.

Step-by-step explanation:

To find the total number of tablets that covers the order, we can divide the order total mg over each tablet mg.

\frac{TotalOrderMg}{SingleTabletMg} = \frac{75 mg}{30 mg} = 2.5 mg

  • Assuming that tablets can be devided, we can express the previous result in fractions

        2.5 = \frac{25}{10} = \frac{5}{2} = \frac{4}{2} + \frac{1}{2} = 2\frac{1}{2}

  • Assuming that tablets cannot be devided, we need to cover 2 tables and a half, then we will need 3 tables.

What is the scale for 3 cm on the map correspond to 120 km in the actual distance?
nikdorinn [45]

Actual Distance =120 Km

We have to map 120 Km in the scale of  3 Cm.

i.e, 3 Cm = 120 Km

→  1 cm = (120÷3) Km

→ 1 cm = 40 Km

So, if you scale 3 cm on the map correspond to 120 km,then

you have to scale , 1 Cm= 40 Km

Drawn the graph for you below.

Tim is 3 times as old as chris and is also 14 years older than chris. how old is tim?
Luda [366]

Let y represent Tim's age and let x represent Chris's age.

y=3x

y=x+14

Set the two equations equal to each other:

3x=x+14

Subtract the x from the one side to get it on the other side.

2x=14

Divide by 2 on both sides

14/2=7

x=7

Plug it back in and see if it works:

y=3(7)=21

Other equation:

7+14=21

x=7

y=21
