5.2 x 10-2 and 5.2 x 10-1
9*12=108
4*x=4x
so, 4x/108
4x=108
x=27
Answer: the final mass of the solid is 176 grams.
Step-by-step explanation:
The "change" between two quantities, one initial Qi and one final Qf is defined as:
Change = Qf - Qi.
In this case, the quantity is mass, and we know that the initial mass is 260 grams.
And we also know that the change is -84 grams.
Then we have the equation:
Qf - 260 g = -84g
Qf = -84g + 260g = 176g
So the final mass of the solid is 176 grams.
The simplest ratio is 1/3. Equivalent ratios would be 3/9 and 5/15.
Since JN = NK, this means that JK has been split into two equal pieces
This points to the fact that the smaller triangle is half of the larger triangle in terms of side lengths
MN = 14 which means LK is twice as long, so LK = 2*MN = 2*14 = 28
In summary,
LK = 28
