Answer:
243 trees were saved.
Step-by-step explanation:
Recycling one metric ton (1000 kg) of corrugated cardboard will save number of trees = 17
Warehouse recycled 14327 kg of cardboard last year. So we have to find the number of trees saved.
To find the number of trees we will use the unitary method.
∵ Recycling 1000 kg of cardboard number of trees saved = 17
∴ Recycling 1 kg cardboard number of trees saved =
∴ 14327 kg cardboard will save the number of trees =
= 243.559
≈ 243 trees
Therefore, 243 trees were saved.
The standard form of a quadratic equation is
,
where ,
, and
are coefficients. You want to get the given equation into this form. You can accomplish this by putting all the non-zero values on the left side on the equation.
In this case, the given equation is
Since is on the right side of the equation, we subtract that from both sides. The resulting equation is
Looking at the standard form equation , we can see that
