Answer:
The answer is 48.
Step-by-step explanation:
There are 4 triangles in each square. So multiply 4 by 12 because thats how many squares there are.
Answer:
Step-by-step explanation:
Remember
You are given the fraction
First, multiply the numerator and the denominator by -2-3i:
This gives you 13 in denominator, now multiply two complex numbers in numerator:
Thus, the initial fraction is
H = 70ft.
P = 35ft.
B = ?
H^2 = P^2 + B^2
70×70 = (35×35) + B^2
B^2 = 4900-1225
B = √3675
B = 35√3 ft.
Then the answer is 17 minus 8 times the square root of 2, or 5.68629
Without needing fancy formulas, we can conclude that after 10 years, half of the substance will be left. So, we can make our own formula:
amount remaining = 1 / 2^(years/10)
So, after 5 years
amount remaining = 1 / 2^(5/10)
amount remaining = 1 / 2^(.5)
amount remaining = 1 /
