Answer:

See detailed explanation.

Explanation:

Hello,

In this case, since the International Prototype of the Kilogram (IPK) is an object made of a platinum-iridium alloy that was used to define the magnitude of the mass of the kilogram as it weights 2.2 pounds or approximately 1 kg, yet it was replaced by a new definition of the kilogram based on physical constants. In such a way, it is important because it was the base for the current understanding of what a kilogram is and its relationship with other mass measurements.

Thus, if would not have existed, we were not be able to design and use balances or mass-measuring equipment in order to provide a reliable measure of the real mass of an object.

Best regards.

In Europe gasoline is often sold in liters. If a typical fill-up requires 11 gal of gas, how many liters are necessary?

egoroff_w [7]

Answer:

41,64 liters

Explanation:

In order to change the units we need to know the equivalence of said units.

1 gal of gas equals to 3,78541 liters.

We can use cross-multiplication in order to convert it into liters:

$\frac{1 gal}{3.78541 L} = \frac{11 gal}{X} \\\\X= \frac{3.78541 L x 11 gal}{1 gal}$

A typical fill-up requires 41,64 liters.
