Answer:
Step-by-step explanation:
- Initial amount = 2112 g
- Time = 188 days
- Half-life = 47 days
188 days / 47 days = 4 periods
<u>Mercury left after 188 days:</u>
- 2112 * (1/2)^4 =
- 2112* 1/16 =
- 2112/16 =
- 132 g
Yupz u b right cuz 8+9 is ur answer Don’t be so hard on yourself take it easy
Answer:
B. x = 7, y = 4√2
Step-by-step explanation:
Drop a vertical from the upper left corner
This creates a rectangle and a 45-45-90 triangle
The bottom of the rectangle is 3
The legs of the triangle are 4
Therefor
x = 4 + 3
x = 7
For a 45-45-90 triangle
the hypotenuse = leg * √2
y = 4√2
Answer:
1005
Step-by-step explanation:
If you just kept subtracting from 2580 then the next and then the next number you would get 1005
This is true.
Example:
= 8/9 ÷ 7/3
to divide fractions, multiply by the reciprocal/inverse of 7/3
= 8/9 * 3/7
= (8*3)/(9*7)
multiply numerators; multiply denominators
= 24/63
simplify
= 8/21
ANSWER: This is (A) true
Hope this helps! :)
