The half-life of a substance is the amount of time it takes for half of the amount of substance to decay. The half-life of a pesticide is 2 years. Initially there are 500 grams of pesticide. How much pesticide is left after 10 years? Round to the nearest hundredth.

Answers

Answer:

15.625 grams

Step-by-step explanation:

The decay is First order reaction

The half life of the first order reaction is given by

T(1/2)  = ㏑2/K

where K is the reaction constant for the first order reaction

T(1/2) = 2

2 = ln 2 /K

K = ln2/2

The equation of the first order reaction is given by

Kt = ln ([tex]\frac{Ro}{R}[/tex])

where

t = time = 10years

Ro = initial concentration

R = amount left after time t

upon substituting the values

[tex]\frac{ln2}{2}*10 = ln( \frac{500}{R})[/tex]

5ln2 = ln (500/R)

ln [tex]2^5[/tex] = ln (500/R)          (a*lnb = ln[tex]b^a[/tex])

[tex]2^5 = 500/R[/tex]

R = 500/32  = 15.625grams

Therefore the amount of pesticide left after 10 years is 15.625grams

in an examination ,80%examines passed in English ,70%in mathematics and 60% in both subject if 45 examines failed in both find the number of examines who passed only one subject also the number of examines who failed mathematics​

Answers

Answer:

135 and 135

Step-by-step explanation:

The computation is shown below:

The number of examiners who passed in only one subject is as follows

=  n(E) - n(E ∩M) + n(M) - n(E ∩M)

= (80 - 60 + 70 - 60)%

= 30%

Now the number of students who passed in minimum one subject is

n(E∪M) = n(E) + n(M) -  n(E ∩M)

= 80 - + 70 - 60

= 90%

Now the number of students who failed in both subjects is

= 100 - 90%

= 10% of total students

= 45

So total number of students appeared for this 450

So, those who passed only one subject is

= 450 × 30%

= 135

Now the Number of students who failed in mathematics is

= 100% - Passed in Mathematics

= 100% - 70%

= 30% of 450

= 135

Explanation:

Solving Inequality is almost the same as equation. However, you have to know one thing about solving an Inequality.

That is whenever you move the negative coefficient of the variable, you have to swap the sign of Inequality.

[tex]-\frac{1}{2}x<-12[/tex]

Reminder that

[tex]-\frac{1}{2}x=-\frac{x}{2}[/tex]

We use negative x above 2 instead (Easier in solving)

[tex]-\frac{x}{2}<-12[/tex]

Then we move 2 to divide -12.

[tex]-x<-12(2)\\-x<-24[/tex]

Because the coefficient for x is in negative. We move -1 to divide -24 as we get 24 (Because negative divide negative = positive)

But remember that "whenever you move the negative coefficient of the variable, you have to swap the sign of Inequality."

So we change from < to > instead.

Solve in simultaneou linear equation.
The total cost of bag and an umbrella is Rs 2000.If the cost of the bag is Rs 1000 less five times the cost of the umbrella ,find the cost of each of these two items.

Answers

Answer:

The bag costs 1500, while the umbrella cost 500

Step-by-step explanation:

Let the cost of the bag be b and the cost of the umbrella be u

Total cost is;

b + u = 2,000 •••••(i)

From the second part of the question;

b = 5u-1000 ••••••(ii)

Substitute ii into i

5u-1000 + u = 2000

6u = 2000 + 1000

6u = 3000

u = 3000/6

u = 500

To get b, substitute the value of u into equation ii

b = 5(500)-1000

b = 2500-1000

b = 1500

What is the lines for and how do I solve X with them?

Answers

Answer:

the lines represent absolute value bars

[tex]x=0,10[/tex]

Step-by-step explanation:

STEP 1: Move all terms not containing |5−x| to the right side of the equation.

[tex]3|5-x|=15[/tex]

STEP 2: Divide each term by 3 and simplify.

[tex]|5-x|=5[/tex]

STEP 3: Remove the absolute value term. This creates a ± on the right side of the equation because |x|=±x.

5-x=±5

STEP 4: Set up the positive portion of the ± solution.

[tex]5-x=5[/tex]

STEP 5: Solve the first equation for x.

[tex]x=0[/tex]

STEP 6: Set up the negative portion of the ± solution.

How do I find the measure of angle H?

Answers

Answer: 110 degrees

Step-by-step explanation:

Similar polygons have the exact same angles. So we can fill in 60 for angle E, because it matches up with angle A.

The angles in a quadrilateral add to 360 degrees.

So 60 + 100 + 90 + Angle H = 360

If we solve for angle H, we get that angle H = 110 degrees.
