An element with a mass of 640 grams decays by 19.3% per minute. To the nearest
tenth of a minute, how long will it be until there are 50 grams of the element
remaining?

Answers

Answer 1

it will take approximately 6.8 minutes until there are 50 grams of the element remaining.

We can use exponential decay formula to solve this problem:

A = A₀ ×e²(-rt)

where A is the amount of the element remaining, A₀ is the initial amount, r is the decay rate (as a decimal), t is the time elapsed.

We know that the initial mass of the element is 640 grams, the decay rate is 19.3% per minute, and we want to find the time it takes for there to be 50 grams of the element remaining. So we can write:

50 = 640 ×e²(-0.193t)

Dividing both sides by 640, we get:

0.078125 = e²(-0.193t)

Taking the natural logarithm of both sides, we get:

ln(0.078125) = -0.193t

Solving for t, we get:

t = ln(0.078125) / (-0.193)

t ≈ 6.8 minutes

Therefore, it will take approximately 6.8 minutes until there are 50 grams of the element remaining.

Answer 2

Answer:

Please mark me the brainliest

Let's denote the time in minutes by t, and the mass of the element at time t by m(t). Then we can write an exponential decay equation:

m(t) = m(0) * (1 - r)^t

where m(0) is the initial mass of the element, r is the decay rate as a decimal (19.3% = 0.193), and t is the time in minutes.

We know that the initial mass is m(0) = 640 grams, and we want to find the time t when the mass has decreased to 50 grams. So we can set up the following equation:

50 = 640 * (1 - 0.193)^t

Simplifying:

0.07796875 = 0.807^t

Taking the natural logarithm of both sides:

ln(0.07796875) = ln(0.807^t)

Using the property of logarithms that ln(a^b) = b * ln(a):

ln(0.07796875) = t * ln(0.807)

Dividing both sides by ln(0.807):

t = ln(0.07796875) / ln(0.807)

Using a calculator, we get:

t ≈ 24.9

Therefore, to the nearest tenth of a minute, it will take 24.9 minutes until there are 50 grams of the element remaining.

How to find the diameter of the circle?

The length of an arc of a circle is given by the formula:

L = θ/360 * πd

where θ is the measure of the angle and is the diameter of the circle

Given: θ = 80° and L = 88π

L = θ/360 * πd

88π = 80/360 * π * d

88 = 80/360 * d

80 * d = 88 * 360

80d = 31680

80d = 31680/80

d = 396 units

At a local college, 82 of the male students are smokers and 328 are non-smokers. Of the female students, 148 are smokers and 252 are non-smokers. A male student and a female student from the college are randomly selected for a survey. What is the probability that both are smokers?

Answers

Let's start by calculating the probability that a male student is a smoker:

P(male smoker) = 82 / (82 + 328) = 0.20

Similarly, the probability that a female student is a smoker is:

P(female smoker) = 148 / (148 + 252) = 0.37

To calculate the probability that both are smokers, we need to multiply these probabilities:

P(both smokers) = P(male smoker) x P(female smoker)
P(both smokers) = 0.20 x 0.37
P(both smokers) = 0.074

Therefore, the probability that both a male and a female student selected at random from the college are smokers is 0.074, or approximately 7.4%.

Solve the system of equation algebraically y =
x ^ 2 + 4x + 3 y = 2x + 6

Answers

We have two equations:

y = x ^ 2 + 4x + 3 --- Equation 1
y = 2x + 6 --- Equation 2

We can set the right-hand sides of the two equations equal to each other since they are both equal to y:

x ^ 2 + 4x + 3 = 2x + 6

Subtracting 2x + 6 from both sides, we get:

x ^ 2 + 2x - 3 = 0

We can factor the quadratic equation:

(x + 3)(x - 1) = 0

This gives us two possible solutions:

x + 3 = 0 or x - 1 = 0

Solving for x, we get:

x = -3 or x = 1

Substituting these values back into either Equation 1 or Equation 2, we can solve for y:

When x = -3, y = (-3) ^ 2 + 4(-3) + 3 = 0
When x = 1, y = 2(1) + 6 = 8

Therefore, the solution to the system of equations is (x, y) = (-3, 0) and (1, 8).

Solve each inequality given that the function f is increasing over its domain

1.f(2x+3)>f(3x-2), Df=[3,infinity)
2f(x^2-2)

Answers

Answer:

Since f is increasing over its domain, we know that if a > b, then f(a) > f(b). Therefore, we have:

2x + 3 > 3x - 2

Solving for x, we get:

x < 5

So the solution set is:

Df = [3, infinity) intersect (-infinity, 5) = [3, 5)

Therefore, the inequality is true for all x in the interval [3, 5).

Since f is increasing over its domain, we know that if a > b, then f(a) > f(b). Therefore, we have:

x^2 - 2 < y^2 - 2

Simplifying, we get:

x^2 < y^2

Taking the square root of both sides, we get:

|x| < |y|

So the solution set is:

Df = [3, infinity)

|x| < |y| means that either x < y or -x < y. Therefore, the solution set can be divided into two parts:

Part 1: x^2 - 2 < 0, i.e., x is in the interval (-sqrt(2), sqrt(2)). For this part, we have:

Df intersect (-sqrt(2), sqrt(2)) = empty set

Part 2: x^2 - 2 >= 0, i.e., x is outside the interval (-sqrt(2), sqrt(2)). For this part, we have:

Df intersect (-infinity, -sqrt(2)] union [sqrt(2), infinity) = [3, infinity)

Therefore, the inequality is true for all x in the interval [3, infinity) except for the interval (-sqrt(2), sqrt(2)).

The Sky Train from the terminal to the rental car and long term parking center is supposed to arrive every 8 minutes. The waiting times for the train are known to follow a uniform distribution.

What is the probability of waiting less than 2 minutes or more than 6 minutes?

Answers

The probability of waiting less than 2 minutes or more than 6 minutes for the Sky Train is 0.5 or 50%.

To calculate the probability of waiting less than 2 minutes or more than 6 minutes for the Sky Train from the terminal to the rental car and long term parking center, we need to find the probability of each event separately and then add them together.

The probability of waiting less than 2 minutes can be calculated as the ratio of the time interval from 0 to 2 minutes (2 minutes) to the total time interval of 8 minutes;

P(waiting less than 2 minutes) = (2 minutes) / (8 minutes) = 0.25

The probability of waiting more than 6 minutes can be calculated as the ratio of the time interval from 6 to 8 minutes (2 minutes) to the total time interval of 8 minutes;

P(waiting more than 6 minutes) = (2 minutes) / (8 minutes) = 0.25

Now, to find the probability of waiting less than 2 minutes or more than 6 minutes, we can add the two probabilities together;

P(waiting less than 2 minutes or more than 6 minutes) = P(waiting less than 2 minutes) + P(waiting more than 6 minutes)

= 0.25 + 0.25

= 0.5

Therefore, the  probability of waiting less than 2 minutes or more than 6 minutes will be 0.5 or 50%.

The position of an object is determined as  (¹/₃ ln |1 + t³| + 2)i + (- ¹/₂cos(2t) + 3 )j.

None of above is the correct answer.

What is the particle's position?

The position of an object is defined as the product of velocity of the object and the time of motion of the object.

So to obtain the position of the particle, we will integrate the velocity of the particle as follows;

The velocity is given as;

v(t) = t²i/(1 + t³)  +  sin 2t j

Integrate i component as;

Let u = 1 + t³

du/dt = 3t².

dt = du / (3t²)

∫ t²/(1 + t³) dt =∫ (1/u) x (t²/3t²) du

= (1/3) ∫ (1/u) du

= (1/3) ln |u| + C

= (1/3) ln|1 + t³| + C

Integrate j component as follows;

∫ sin(2t) dt = - ¹/₂cos(2t) + C

∫ v(t) dt = (1/3) ln|1 + t³|)i - ¹/₂cos(2t)j

So finally, we add the initial position of 2i + 3j, as follows;

Answers

The surface area of a right square pyramid if the area of the base is 169 cm² and the slant height of the pyramid is 13 cm is 507 cm².

Calculating the surface area of square pyramid

We know that the area of the square base is 169 cm², so we can solve for the length of one side.

To find the length, we use the formula for the area of a square:

Area = length x length

169 = length²

Taking the square root of both sides, we get:

length = √169

        = 13 cm

Now we can use the formula for the surface area of a square pyramid:

Surface area = area of base + (1/2)perimeter of base x slant height

The perimeter of the base is 4 times the length of one side, so it is:

perimeter of base = 4 x length = 4 x 13 cm = 52 cm

Plugging in the values we have:

Surface area = 169 cm² + (1/2)(52 cm)(13 cm)

Surface area = 169 cm² + 338 cm²

Surface area = 507 cm²

Therefore, the surface area of the right square pyramid is 507 cm².

A car costing $34,000 is leased for $473 monthly over 5 years with a $2,420 down payment. The car’s residual value is estimated to be $16,400. If the car is purchased with a $5,000 down payment, the monthly loan payments will be $623 for 60 months. Calculate the costs of leasing this car and buying this car. Is buying or leasing less expensive and by how much less?

Answers

The cost of leasing the car is $28,780 and the cost of buying the car is $42,380.

Buying the car is more expensive than leasing by $13,600 over the 5-year period.

We have,

To calculate the cost of leasing the car, we first need to determine the total amount paid over the lease term:

= (Monthly payment x Number of months) + Down payment

= ($473 x 60) + $2,420

= $28,780

To determine the cost of buying the car, we first need to calculate the total loan amount:

= Cost of car - Down payment + Residual value

= $34,000 - $5,000 + $16,400

= $45,400

Now,

Total loan cost = (Monthly payment x Number of months) + Down payment

Total loan cost = ($623 x 60) + $5,000

Total loan cost = $42,380

So,

The cost of leasing the car is $28,780 and the cost of buying the car is $42,380.

To determine which option is less expensive, we can subtract the cost of leasing from the cost of buying:

Cost of buying - Cost of leasing = $42,380 - $28,780

Cost of buying - Cost of leasing = $13,600

So,

Buying the car is more expensive than leasing by $13,600 over the 5-year period.

Thus,

The cost of leasing the car is $28,780 and the cost of buying the car is $42,380.

Buying the car is more expensive than leasing by $13,600 over the 5-year period.

Find x round your answer to nearest tenth of a deggre triangle that had 16 20 and x

Answers

In the given right triangle, the angle opposite the side of length 16 units has a measure of 49.6 degrees.

We have a right triangle with an unknown angle θ (measured in degrees), the opposite side length of 16 units, and a hypotenuse length of 21 units. We're given the formula for calculating the sine of an angle:

sin(θ) = opposite / hypotenuse

By substituting the values we know, we get:

sin(x) = 16 / 21

x = sin⁻¹(16 / 21)

x ≈ 49.6°

Therefore, in the given right triangle, the angle opposite the side of length 16 units has a measure of 49.6 degrees.

The probability of success is 2 If the second mall is selected, it is estimated that the yearly profit will be $700.000 if successful; otherwise, the annual loss will be $210.000. The probability of success at the second mall is
_ Complete parts (a) through (c) below
a. What is the expected profit for the first mall?

Answers

The expected profit for the first mall is $1,750,000

Given data ,

Let the probability be represented as A and B

Now , For Event A:

Probability of success at the first mall (P(A)) = 2 (given)

Profit if successful (P(A) * Profit | Success) = 2 * $1,050,000 = $2,100,000

Loss if unsuccessful (Loss | Failure) = -$350,000

For Event B:

Probability of success at the second mall (P(B)) = unknown (to be calculated)

Profit if successful (P(B) * Profit | Success) = P(B) * $700,000

Loss if unsuccessful (Loss | Failure) = -$210,000

Expected Profit for Event A = P(A) * Profit | Success + (1 - P(A)) * Loss | Failure

Expected Profit for Event A = 2 * $1,050,000 + (1 - 2) * -$350,000

Expected Profit for Event A = $2,100,000 - $350,000

Expected Profit for Event A = $ 1,750,000

Hence , the profit is $ 1,750,000

The variables to the parallelogram OPQR are;

1. coordinates of points M is (1, 2.5)

2. The length of PQ is 4

3. The length of QR is 5.4

4. The length of PM is 3.9

5. The length of OM is 2.7

6. The perimeter of the parallelogram OPQR is approximately  18.8

7. if m ∠QMR = 120° m ∠ QMP = 60°

8. If m ∠ QRO = 80°  m ∠ROP =  100°

How do we calculate for every listed sides of the of parallelogram OPQR?

To calculate for every listed length of parallelogram OPQR it will be helpful to list all the coordinate for this diagram and they are;

O (0, 0)

p (-2, 5)

R (4, 0)

Q (2, 5)

To find for M, we could just get it from the diagram by looking at the points for x and then y. This is (1, 2.5). You can also calculate it like this

Mx = (Px + Rx)/2 = (-2 + 4)/ 2 = 2/2 = 1

My = (Py + Ry)/2 = ( 5 + 0)/2 = 2.5

To calculate for the length of any side, we say

LPQ = √(Qx -Px)² + (Qy - Py)² = √(2 - -2)² + (5-5)² = √8 = 4

LQR = √(Rx -Qx)² + (Ry - Qy)²

LPM = √(Mx -Px)² + (My - Py)²

LOM = √(Mx -Mx)² + (Oy - My)²

if m∠QMP = 180° - m∠QMR = 180° - 120° = 60°

The question below is as seen in the pictures provided.

You are remodeling a kitchen, including the formal dining room and breakfast nook. It is time to purchase flooring for the space. You need to calculate the area of the entire space and then find the cost of the materials that you would like to purchase to make sure you do not go over your budget of $7,500. See the picture for your blueprint.

Answers

The area of the entire space is 38.57 units².

We have,

From the figure,

Total area.

= Semicircle + Rectangle + Trapezium + Rectangle

Now,

Semicircle:

Radius = 2 units

Rectangle:

Length = 4 units

Width = 3 units

Trapezium:

Parallel sides = 5 units and 3 units

Height = 1 unit

Rectangle:

Length = 2 units

Width = 5 units

Now,

Area of the entire space.

= πr² + 4 x 3 + 1/2 x 1 x (5 + 3) + 2 x 5

= 22/7 x 2 x 2 + 12 + 1/2 x 1 x 8 + 10
= 88/7 + 12 + 4 + 10

= 12.57 + 12 + 4 + 10

= 12.57 + 26

= 38.57 units²

Now,

1 unit = 7 feet

So,

= 38.57 X 7² feet²

= 1889.93 feet²

Thus,

The area of the entire space is 38.57 units².
