Split the figure into 3 shapes: a trapezoid,a rectangle and a triangle
Area of trapezoid
A= 1/2(b1+b2) h
A = 1/2(3 +9)(8)
A = 1/2(12)(8)
A = 48 square units
Area of rectangle:
A = L x W
A = 9 x 8
A = 72 square units
Area of triangle
A = 1/2bh
A = 1/2(3)(8)
A = 12 square units
Area of figure = 48 square units + 72 square units + 12 square units
= 132 square units
Answer
132 square units
Answer:
2
Step-by-step explanation:
Factors for 18: 1, 2, 3, 6, 9, 18
Factors for 16: 1, 2, 4, 8, 16
Common factors are: 1, 2. 2 is the greatest digit in this case so this is your final answer.
The answer is 4 because 24 divided by 7 is 4
Answer:
The half life of the substance is approximately 346.6 years
Step-by-step explanation:
Recall that the half life of a substance is the time it takes for it to decay to half its initial value. That is, based on the formula:
the time it takes for M(t) to reach half of its initial value "700 grams" as per the equation provided. That is 350 grams. So we set the equation that imposes this condition, and solve for the time needed making sure we use logarithms in the process in order to bring the exponents down for the solving:
which can be rounded to about 346.6 years
