Subtract 16 L 18 CL 9 ml from 85 L

harkovskaia [24]

Answer:

(1) 68.811 L

Step-by-step explanation:

The amount being subtracted is ...

16 + 0.18 + 0.009 = 16.189 . . . . liters

The difference is ...

85.000 -16.189 = 68.111 . . . liters

Additional comment

cL is the SI unit "centiliters." The prefix "centi-" mean 1/100 or 0.01 units. Then 18 cL = 18 × 0.01 L = 0.18 L.

mL is the SI unit "milliliters." The prefix "milli-" means 1/1000 or 0.001 units. Then 9 mL = 9 × 0.001 L = 0.009 L.

Determine whether the relationship is an inverse variation or not. Explain.

kolbaska11 [484]

Answer: The product xy is not constant, so the relationship is not an inverse variation.

Step-by-step explanation:

For it to be an inverse variation, the product of x and y must be constant.

For the first row, xy=2(424)=848.
For the second row, xy=3(280)=840.
For the third row, xy=4(210)=840.

This means the product xy is not constant, so the relationship is not an inverse variation.

A castle has to be guarded 24 hours a day. Five knights are ordered to split each day's guard duty equally. How long will each k

Harman [31]

Answer:

Each knight will guard 288 minutes in one day.

Step-by-step explanation:

Given:

A castle has to be guarded 24 hours a day. Five knights are ordered to split each day's guard duty equally.

Now, to find the minutes will each night spend on guard duty in one day.

As, in 1 hour there are 60 minutes.

Thus, in 24 hour there are 60 × 24 = 1440 minutes.

Total minutes for guarding = 1440 minutes.

So, there are knights ordered for guarding are = 5.

And each day's guard duty equally.

Now, to get the minutes will each night spend on guard duty in one day we divide the total minutes for guarding by number of knights that is 5:

$1440\div5$

$=288\ minutes.$

Therefore, each knight will guard 288 minutes in one day.
