Using it's concept, it is found that the percent increase in the amount of iron per serving was of 50%.
<h3>What is the percentage increase of a value?</h3>
It is given by the increase divided by the initial value, and subtracted by 100%.
In this problem:
- The initial value is of 1.2 mg.
- The increase was of 1.8 mg - 1.2 mg = 0.6 mg.
Hence the percent increase is given by:
P = 0.6/1.2 x 100% = 50%.

we have that
Step 1
<u>Find the y-intercept</u>
we know that
The y-intercept is the value of f(x) when the value of x is equal to zero
For 
Point 
Step 2

therefore
the answer in the attached figure
Given:
Room is 5 meters by 8 meters.
Measure of squaree tiles is 14-inch.
Approximately 316 tiles are required to floor the room.
The angle sum of quadrilateral is 360 so just 360 - 120- 48 - 92 so the fourth angle should be 100°
the area of triangle is base X height /2 so the answer is 6 x 8 /2 = 24
The answer is B because e is 2.17
