Can someone help me with number 18

You should buy the 0.8 kilogram block of wax because 1000 grams is equal to a kilogram and 1000 milligrams is equal to a gram. If you add all of these up, you will get less than 0.8 kilograms so it will be useless to get way more when you don’t need it.

The weight of an object on the moon varies directly as its weight on earth. A person who weights 150.94lb on earth weighs 25.66l

Veronika [31]

109.93 lbs

since the quantities vary directly, then

w(moon) = kw(earth ) ← ( k is the constant of variation )

to find k use the given condition

k = w( moon ) / w( earth ) = $\frac{25.66}{150.94}$

given w(earth) = 218.24

w(moon) = $\frac{25.66(218.24)}{150.94}$ = 109.93
