A 41 gram sample of a substance that's used to detect explosives has a k-value of 0.1392. Find the substance's half life, in day
-BARSIC- [3]

Answer:

The substance half-life is of 4.98 days.

Step-by-step explanation:

Equation for an amount of a decaying substance:

The equation for the amount of a substance that decay exponentially has the following format:

A(t) = A(0)e^{-kt}

In which k is the decay rate, as a decimal.

k-value of 0.1392.

This means that:

A(t) = A(0)e^{-0.1392t}

Find the substance's half life, in days.

This is t for which A(t) = 0.5A(0). So

A(t) = A(0)e^{-0.1392t}

0.5A(0) = A(0)e^{-0.1392t}

e^{-0.1392t} = 0.5

\ln{e^{-0.1392t}} = \ln{0.5}

-0.1392t = \ln{0.5}

t = -\frac{\ln{0.5}}{0.1392}

t = 4.98

The substance half-life is of 4.98 days.

HELP ME IN CIVICS 80 POINTS Which of the following conclusions can be supported by the information in this chart?
marishachu [46]
Participation in elections increases as education level increases across all age groups. Education level was a significant factor in the outcome of the 2008 election. Decreasing the drop-out rate among high school students will positively affect voting rates. Increasing access to higher education will decrease citizens' participation in government.

3x + 5y = 7<br> How to solve it
Lubov Fominskaja [6]

Answer:

x=1 and y=4/5

Step-by-step explanation:

<u>Given system of equations</u>

3x+5y=7

5x+10y=13

<u />

<u>Multiply first equation by 2</u>

2(3x+5y)=2(7)

6x+10y=14

<u>Eliminate y-variable to get "x"</u>

 6x+10y=14

<u>- 5x+10y=13</u>

         x = 1

<u>Substitute x=1 into either equation and find "y"</u>

3x+5y=7

3(1)+5y=7

3+5y=7

5y=4

y=4/5

Therefore, x=1 and y=4/5

Heidi wants to make some biscuits using this recipe.
Andre45 [30]

The most cookies Heidy can make is 36 cookies.

<h3>How to calculate how many cookies can Heidy make?</h3>

To know how many cookies Heidy can make, you have to take into account the following information:

12 cookies need the following ingredients:

  • 125g butter
  • 200g flour
  • 50g sugar

In the case in which Heidy has more ingredients, we must carry out the following operations:

Divide the quantities, in the reference quantity we have:

  • 500g of butter ÷ 125g of butter = 4
  • 700g flour ÷ 200g flour = 3.5
  • 250g of sugar ÷ 50g of sugar = 5

According to the above, we must take into account the lowest value of all because if that ingredient is enough, we can infer that the rest of the ingredients also.

So the number of cookies Heidy can make are:

12 × 3.5 = 42
