The total area is the sum of the area of the base (65 m^2) and six times the area of one of the triangular sides. This area (of one side) is (1/2)(base)(height), or (1/2)(5)(12), so the total area of the sides is 6(1/2)(5)(12) = 180 m^2. Thus, the total area is 65 m^2 + 180 m^2 = 245 m^2.
Answer:94%
Step-by-step explanation:
Half life of a radioactive element is the time taken for half it's mass to disintegrate away.it means after attaining half life,what will be left is 100-50=50%.
Let the 100% mass of C-14,be x
Then 5730years=1/2 of X
Then 660 years=y of X
Where Y is the fraction of C-14 that has disintegrate as at 1988.
5730/660=1/2X/yX
5730/660=1/2/y
Cross multiplying
5730×y=660×1/2
5730y=330
Y=330/5730=0.05759
In %,5.76%
Amount of C-14 left is
100-5.76=94.24=94% as at 1988.
x=7th root of 30=1.6256
Justification=a process that is both individual and social undetermined in developing
And you have to subtract in the math
Answer:
Step-by-step explanation:
The coordinates of a vertex are (h, k). If our vertex is (-3, -5), then h = -3 and k = -5. The vertex form of a parabola is
so if we fill in our h and k values, the equation becomes
and, simplified, is
Choice B.
Its not factorable
(make sure you typed it up right)
