Answer:
154.2g
Step-by-step explanation:
This is quite straightforward, what we need to add the masses together.
113g + 114g + 27.2g = 154.2g
Yes but it would result in a decimal.
X^3 -4x^2 +7x -28 = x^2(x-4) +7(x -4) = (x^2 +7)(x-4)
so the 4th choice will be right sure

Y=43,000 is a horizontal line on the Y-Axis at 43,000. Horizontal lines have 0 as their slope.
Answer:
15.3 miles.
Step-by-step explanation:
Area of trapezoid is given by = 1/2*( sum of parallel side) height
Given area of trapezoid = 221.85 sq. miles
Length of parallel sides = 19 miles and 10 miles.
Sum of parallel sides = 19 miles + 10 miles = 29 miles.
Plugging the above values in formula for area of trapezoid we have
Area of trapezoid is given by = 1/2*( sum of parallel sides) height
221.85 = 1/2 (29) height
=> 221.85* 2 = 29* height
=> 443.7 = 29* height
=> 443.7/29 = height
=> height = 15.3
Thus, height is 15.3 miles.
