Answer:
A. Yes, because by 2206, the radioactive element remaining in the area is less than 800 Bqs.
Step-by-step explanation:
Function for the amount of radioactivity:
The function for the amount of radioactivity, in t years after 1996, is given by:
Find f(220) to determine the amount of becqurels in 2206.
121.42 < 600, so the area will be safe, and the correct answer is given by option A.
Answer:
m= - 3/6
Step-by-step explanation:
Answer:
a. The difference in rainfall is 4.03in
b. The total amount of rainfall for the year is negative, -1.73
Step-by-step explanation:
a. Wettest month 2.36in and dryest month -1.67in
2.36
-1.67
-------
4.03
b. -0.45 + -0.88 + 0.94 + -1.67 + -0.96 + 0.83 + 2.36 + 1.39 + 0.35 + -1.35 + -0.9 + -1.39 = -1.73
Answer:
2/5 of an acre
Step-by-step explanation:
1/2 an acre, or 5/10 of an acre, is subtracted from 9/10 of an acre
4/10 can be simplified into 2/5 if divided by two
Answer:
y ≈ 4.3
Step-by-step explanation:
Since the figures are similar then the ratios of corresponding sides are equal, that is
= 
, substitute values
= 
( cross- multiply )
6(y + 1) = 32
6y + 6 = 32 ( subtract 6 from both sides )
6y = 26 ( divide both sides by 6 )
y ≈ 4.3 ( to the nearest tenth )
