The half-life of a drug in the bloodstream is 14 hours. What fraction of the original drug dose remains in 36 hours? in 72 hours?
What fraction of the original drug dose remains in 36 hours?
(Do not round until the final answer. Then round to the nearest hundredth as needed.)

Answers

16.82 % and 2.83% of the original drug dose remain in 36 hours and 72 hours respectively.

What is half-life?

Half-life is a characteristic unit for the exponential decay equation and is constant across the lifespan of an exponentially decaying quantity.

Given, the half-life of a drug(h) = 14 hours

The first condition, time duration (t) = 36 hours

Then, the half-life of the substance can be calculated by:

[tex]A = A_{0} * (1/2)^{\frac{t}{h} }[/tex]

or, [tex]A = A_{0} * (1/2)^{\frac{36}{14} }\\A = A_{0} * (0.1682)\\[/tex]

16.82 % of the original drug dose remains in 36 hours

Hence, 16.82 % of the original drug dose remains in 36 hours

The second condition, time duration (t) = 72 hours

Then, the half-life of the substance can be calculated by:

[tex]A = A_{0} * (1/2)^{\frac{t}{h} }[/tex]

[tex]A = A_{0} * (1/2)^{\frac{72}{14} }\\A = A_{0} * (0.0283)\\[/tex]

2.83 % of the original drug dose remains in 72 hours

Hence, 2.83 % of the original drug dose remains in 72 hours

selling price of car if rs 50,000 , profit is 10% and cost price of car will be ?

Answers

Answer:

Rs 45,000

Step-by-step explanation:

The profit is the difference between the selling price and the cost price of the car. In this case, the profit is 10% of the selling price, or 10% * Rs 50,000 = Rs 5,000.

Therefore, the cost price of the car is the selling price minus the profit, or Rs 50,000 - Rs 5,000 = Rs 45,000. This is the amount that the seller paid for the car, before adding the profit.

Given the inequality 4x ≤ 28, which of the following is a solution that makes the inequality true?

Answers

For the inequality 4x ≤ 28 the solution that makes the inequality true will be x≤7.

What is inequality?

It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.

It is given that the inequality is 4x ≤ 28.

Now that the equation has been simplified, we obtain both sides of the inequality equation, divide by 4, and we obtain

The width of a rectangle is 4 more than the length. If the perimeter is 36 cm, ind the dimensions (length and width) of the rectangle.

Answers

Answer with step-by-step explanation:

Let the width of the rectangle be x.

Given that,

length ⇒ 4

width ⇒ x + 4 ( Because, the rectangle's width is 4 more than the length.)

Perimeter ⇒ 36cm

The formula to find the perimeter of rectangle is:

P = 2 ( l + w )

Now to find the value of x replace P, l & w with 36, 4 & (x + 4) with respectively.

P = 2 ( l + w )

36 = 2 ( 4 + x + 4 )

36 = 2 ( x + 8 )

Solve the brackets.

36 = 2x + 16

Substract 16 from both sides.

36 - 16 = 2x

20 = 2x

Divide both sides by 2.

10 = x

And now let us find the exact dimensions of the rectangle.

Length = 4 cm

Width = x + 4 = 10 + 4 = 14 cm

Answers

(a) The probability that the first person selected is a pledge is; 10/35

(b) The probability that the first person selected is not a pledge is; 25/35

How to find the probability of selection?

We are given;

Total number of members in the Sorority = 35

Number of full members = 25

Number of members that are pledges = 10

Formula for probability is;

Probability = Number of Favorable Outcomes / Total Number of Outcomes.

1) Probability that the first person selected is a pledge = number of pledges/total number of members = 10/35

2) Probability that the first person selected is not a pledge = 1 - (Probability that the first person selected is a pledge)

= 1 - 10/35 = 25/35

A rental car agency charges $160 per week plus $0.25 per mile to
rent a car. How many miles can you travel in one week for $335?

Answers

The number of miles travelled by the family in one week is 700 miles

How to determine the number of miles travelled

From the question, we have the following parameters that can be used in our computation:

Charges per week = $160

Charges per mile = $0.25

Total charges = $335

The above parameters mean that

Total charges = Charges per week + Charges per mile x Number of miles

Substitute the known values in the above equation, so, we have the following representation

160 + 0.25 * Number of miles = 335

This gives

0.25 * Number of miles = 175

Multiply both sides by 4

Number of miles = 700

Hence, the number of miles is 700

How to solve a system of equations

Herein we find a system of equations formed by a linear equation and a quadratic equation. This system must be resolved by means of algebra properties. First, write the system of equations:

9 · x + 9 · y - 79 = 0

x² + 5 · x - y - 4 = 0

Second, clear the variable y in the first equation:

9 · x + 9 · y - 79 = 0

9 · y = 79 - 9 · x

y = 79 / 9 - x

Third, substitute y on the second equation:

x² + 5 · x - (79 / 9 - x) - 4 = 0

x² + 6 · x - 115 / 9 = 0

Fourth, use the quadratic equation to find the solutions of x:

x₁ = 5 / 3, x₂ = - 23 / 3

Fifth, calculate the solutions of y:

y₁ = 79 / 9 - x₁

y₁ = 64 / 9

y₂ = 79 / 9 - x₂

y₂ = 148 / 9

The solutions are (x₁, y₁) = (5 / 3, 64 / 9) and (x₂, y₂) = (- 23 / 3, 148 / 9).

Frosting No frosting Total

sugar cookies 56 120 176

Chocolate cookie 66 70 136

Red velvet 38 50 88

Total 160 240 400

Chocolate cookies with frosting = Total chocolate cookies - chocolate cookies with no frosting

Total cookies with no frosting = Total cookies - Total cookies with frosting

= 400 - 160

= 240

Total sugar cookies with no frosting = Total cookies with no frosting - (chocolate cookies with no frosting + Red velvet cookies with no frosting)

= 240 - (70 + 50)

Answers

The circumference of a circle with one-third the curvature of a circle of radius 1 is 18.85 units

What is circumference ?

The perimeter of a circle is known as its circumference. It is the length of the circle's whole perimeter. The diameter of a circle and the constant are multiplied to get the circumference of the circle. This measurement of a circle's circumference is necessary for someone to cross a circular park or for a circle-shaped table to have a border. The units of the circumference are the same as the units of length and it is a linear value.

If a circle has a radius of 1,

the curvature is inversely proportional to this

So, the curvature= 1

A circle with a curvature of 1/3 :

radius=3

Thus, the circumference of the circle = 2 *π * radius

.Ansel wants to borrow $10,000 from the Hampton County Bank. They offered him a 6-year loan with an APR of 6.35 %. How much will he pay in interest over the life of the loan ?

Answers

Ansel has to pay an interest of $167.4 per months for the the life of the loan to the Hampton County Bank.

Explain the term APR?That yearly interest amount you'll spend if you have a balance off your credit card is referred to as the annual percentage rate (APR). Some credit cards feature variable APRs, which means that over time, your rate may go up or down. Your annual percentage rate, which is determined by the particulars of your loan and includes the interest rate as well as additional costs like borrower and mortgages broker fees, is often greater than your interest rate.

The formula for the monthly installments are-

M = P(r/12)(1 + r)∧12t / (1 + r)∧12t - 1

Put the values;

Principal P =$10,000.

Rate of interest r = 6.35%

Time t = 6 years 72 months

M = 10,000(0.0635/12)(1 + 0.0635)∧72 / (1 + 0.0635)∧72 - 1

M = $167.4
