Answer:
The percent increase in iron = 50 %
Step-by-step explanation:
Initial amount of iron per serving = 1.2 mg
After an increase the amount of iron per serving = 1.8 mg
Increase in the amount of iron per serving = 1.8 - 1.2 = 0.6 mg
Percent increase in iron is calculated as
Put the values in above formula we get
= 50 %
Therefore the percent increase in iron = 50 %
Answer:
15.47
Step-by-step explanation:
Since the four is in the hundrenths place you use the digit to the right of it, and if the number is greater than 5 you add one more. Thus the answer being 15.47
add all known angles:
90 + 107 + 144 + 138 = 479
the interior angles of a 5 sided polygon need to equal 540
540 - 479 = 61
x = 61 degrees
200=12th grade for riverside high school.
500=total for that school
200/500=
2/5=
0.4
Perpendicular lines have slopes that are opposite and reciprocal. Therefore, the line we are looking for has a -3 slope.
y= -3x+b
Now, we can substitute in the point given to find the intercept.
2= -3(4)+b
2= -12+b
b=14
Finally, put in everything we've found to finish the equation.
y= -3x+14
