A storage tank contains a liquid radioactive element with a half-life of 96 years. It will be relatively safe for the contents to leak from the tank when 0.02% of the
radioactive element remains. How long must the tank remain intact for this storage procedure to be safe?
The tank must remain intact for lears.
(Round the base of the exponential function to four decimal places. Then round the final answer to the nearest year as needed.)
Answer:
t = 1180 years
Step-by-step explanation:
We will solve this using the radioactive decay formula which is;
A = A_o × 2^(-t/h)
Where;
A = Amount of liquid remaining after time (t)
A_o = initial amount of liquid at initial time
t = time of decay
h = half-life of the liquid
We have;
A_o = 1(we assume it is 100% which is 1)
A = 0.02% = 0.0002
h = 96 years
Thus;
0.0002 = 1 × 2^(-t/96)
0.0002 = 2^(-t/96)
(-t/96)log 2 = log 0.0002
(-t/96) = (log 0.0002)/log 2
(-t/96) = -12.2877
t = 96 × 12.2877 (negative has canceled out)
t = 1179.6192
To the nearest year gives;
t = 1180 years

) A basket filled with tomatoes had a mass of 2330 g. After 3/5 the tomatoes were
taken away, the mass of the basket with the remaining tomatoes was 1550 g
What was the mass of the empty basket?
Answer: 1030 g
Step-by-step explanation:
Given
Mass of basket and the tomatoes is 2330 g
After [tex]\frac{3}{5}[/tex] of tomatoes were taken away, the mass with the basket is 1550 g
Suppose x is the mass of tomatoes and y is the mass of the basket
[tex]\therefore x+y=2330\quad \ldots(i)\\\\y+(1-\dfrac{3}{5})x=1550\\\\y+\dfrac{2}{5}x=1550\quad \ldots(ii)[/tex]
Solve the above equations. We get
[tex]x=1300,y=1030[/tex]
So, the mass of the empty basket is 1030 g.

The Gordon family has a disposable annual income of $44,350. They spend 19% of their disposable income for food. How much do they spend weekly for food (Note: There
are 52 weeks in a year)?
$149.43
$158.77
$162.05
$165.23
None of these choices are correct.
Answer:
$162.05
Step-by-step explanation:
Calculation to determine How much do they spend weekly for food
Using this formula
Amount spent weekly=(Annual Disposable income*Disposable income percentage)/Numbers of weeks in a year
Let plug in the formula
Amount spent weekly=($44,350*19%)/52 weeks
Amount spent weekly=$8,426.5/52 weeks
Amount spent weekly=$162.048
Amount spent weekly=$162.05 (Approximately)
Therefore the amount they spent weekly for food is $162.05

A serving of rice is 1/3 of a cup. How many servings are there in a 1 1/3-cup bag of rice?
Answer:
4 cups
Since 1 1/3 is 1/3 x 4 that means there are 4 servings
Hope this Helps!
========================================================
Explanation:
It might help to imagine that you had a measuring spoon that is 1/3 cup. Note how exactly three of them gets you to a full cup since 3*(1/3) = 3/3 = 1.
Adding another helping of the measuring spoon gets you to the mixed number of 1 & 1/3. This is because the mixed number 1 & 1/3 is identical to the math expression 1 + (1/3). We add the fractional portion 1/3 on top of the whole number 1. That's why the verbal form of this is "one and one-third". The "and" says "add" more or less.
In short, we need 3 servings to get to one full cup. Then that fourth serving will get us to 1 & 1/3 cup.

What is the probability of reaching in twice and first pulling out a blue item and then either a red pencil or a black pen WITH REPLACEMENT
Answer:
= 2608/8729 which is approx. 30%
Step-by-step explanation:
Probability (Blue, Red Pencil OR Black Pen)
= 16/43 x (4/14 + 15/29)
= 16/43 x 163/203
= 2608/8729

A Union worker is to see an increase in pay of 2.5% per year next year. Her salary is $41,000/yr. If inflation was predicted to be 1.9% for the upcoming year, how much more purchasing power would she have in dollars next year?
Answer:
i need points rq thanks so much
Step-by-step explanation:
imma go waste these points now
She'll have $246 more purchasing power.
Current salary per year = $41000
Next year salary = $41000 × (2.5% × $41000)
= $41000 + (0.025 × $41000)
= $41000 + $1025
= $42025
Effect of Inflation will be:
= $41000 + (1.9% × $41000)
= $41000 + (0.019 × $41000)
= $41000 + $779
= $41779
Therefore, the difference will be:
= $42025 - $41779
= $246

Use the following dot plot to answer the questions.
What is the mean of the set?
If an additional dot is added to the set in the 3 column, how will the mean change? What will the new mean be?
Answer:
3.4
Decrease ; 3.375
Step-by-step explanation:
Mean = Σfx / Σf
Σfx = (1 * 2) + (2 * 2) + (3 * 3) + (4 * 9) = 51
Σf = 1 + 2 + 3 + 9 = 15
Mean = 51 / 15 = 3.4
If 1 more dot is added to the 3rd column:
Σfx = (1 * 2) + (2 * 2) + (3 * 4) + (4 * 9) = 54
Σf = 1 + 2 + 4 + 9 = 16
Mean = 54 / 16 = 3.375
Derive the equation of the parabola with a focus at (2, 4) and a directrix of y = 8.
Answer:
In this problem, given the focus at (2,4) and directrix at y = 8. then it is implied that the parabola is facing downwards. The vertex hence is at the middle of the focus and the directrix, hence at (2, 6). The general formula of the parabola is y-k = -4a ( x-h)^2. Substituting, y -6 = -1/8 *(x-2)^2. Answer is A.
