After 106 minutes, the amount of the iodine left is:

R = 54,544g/4 = 13,636 grams

For a radioactive element, the half-life is the time in which the initial amount of the element is reduced to its half.

Here the half-life is 53 minutes, then 106 minutes is equivalent to two half-lifes.

This means that after that time, the amount of the iodine is reduced to its half two times (so its reduced to a fourth of the initial amount).

Here the initial amount is 54,544 grams, so after 106 minutes we will have:

R = 54,544g/4 = 13,636 grams

For the given triangle:

Use the equation above to solve x:

8/21 of the lawn still needs to be mowed.

To compare fractions, we need a common denominator. The least common multiple of 7 and 3 is 21.

Miss Lianto's fraction: (2/7) x (3/3) = 6/21

Son's fraction: (1/3) x (7/7) = 7/21

To calculate how much of the lawn still needs to be mowed, we can subtract the combined fractions mowed from the total:

Combined fractions mowed: 6/21 + 7/21 = 13/21

So, Remaining fraction: 1 - 13/21 = 8/21

Therefore, 8/21 of the lawn still needs to be mowed.

Answer:

150

Step-by-step explanation:

Since y is directly proportional to sqrt((x+2)^2), there is a constant,k, such that

y=ksqrt((x+2)^2)

We are given a pair (x,y) in this relation. Let's plug in (8,250 ) to find k.

250=ksqrt((8+2)^2)

250=ksqrt((10)^2)

250=k10

250/10=k

25=k

So for any pair (x,y) we have the relation y=25((x+2)^2).

We are asked to find y when x=4.

y=25((4+2))^2

y=25(6)

y=150

Test to see if y is proportional to sqrt((x+2)^2)

For the given points: 250/150=10/6

The equation is true so we're great.

The equivalent choices are (A) sqrt 3 and (F) sqrt 5. We can simplify the given quotient by rationalizing the denominator.

To do this, we multiply both the numerator and denominator by the conjugate of the denominator, which is sqrt 15. This gives us:

sqrt 75 / sqrt 15 = (sqrt 75 / sqrt 15) * (sqrt 15 / sqrt 15) = sqrt (75 * 15) / 15 = sqrt 1125 / 15

Now we can simplify the numerator by factoring out perfect squares. We have:

sqrt 1125 = sqrt (225 * 5) = sqrt 225 * sqrt 5 = 15 * sqrt 5

Substituting this back into our expression, we get:

sqrt 75 / sqrt 15 = (15 * sqrt 5) / 15 = sqrt 5

Therefore, the equivalent choices are (A) sqrt 3 and (F) sqrt 5. Choice (B) 5 is not equivalent because it does not have a square root, while (C) sqrt 15 / sqrt 3 and (D) sqrt 25 / sqrt 5 are not equivalent because they are not in simplest form. Choice (E) 15/3 is equivalent to 5 but not to the given expression sqrt 75 / sqrt 15.

The total value of the furniture sold by Joyce last week is A = $ 6,733.33

Given data ,

Let's call the value of the furniture Joyce sold "x".

She receives 10% commission on the first $1,200 of sales, which is $120:

Commission on first $1,200 = 0.1 * 1200 = 120

The remaining sales that she earns commission on is the difference between the total value of the furniture sold and the first $1,200:

Remaining sales = x - 1200

She earns 15% commission on the remaining sales, which is 0.15 times the remaining sales:

Commission on remaining sales = 0.15 * (x - 1200)

Her total earnings from commission last week was $950. So we can write an equation:

Commission on first $1,200 + Commission on remaining sales = $950

Substituting the expressions we found for the two commissions, we get:

120 + 0.15(x - 1200) = 950

120 + 0.15x - 180 = 950

On simplifying the equation , we get

0.15x - 60 = 950

0.15x = 1010

x = 6,733.33

Hence , the value of the furniture Joyce sold last week was $6,733.33

Answer:290

Step-by-step explanation:

first look at the ones place it is greater than 4 so round up  

286 to the nearest tenth is 290.

Place value, which is related to a digit's location in a number, is the amount that each digit is worth.

Given:

The number is 286.

The digit in tenth place is 6.

And the number 6 is greater than the number 4.

And 6 > 4.

So, the number will round off to the nearest tenth.

6 becomes zero.

And the number left to 6 will increase by 1.

That means 8 + 1 = 9.

The area of the rectangle is 18 \(inch^{2}\) and the perimeter is  \(16\frac{34}{35}\) inches.

To find the value of Az in the geometric sequence, we can use the given information. The geometric sequence is represented as follows: A3, 60, 160, 06 = 9.

From this, we can see that the third term (A3) is 60 and the common ratio (r) is 160/60.

To find Az, we need to determine the value of the nth term in the sequence. In this case, we are looking for the term with the value 9.

We can use the formula for the nth term of a geometric sequence:

An = A1 * r^(n-1)

In this formula, An represents the nth term, A1 is the first term, r is the common ratio, and n is the position of the term we are trying to find.

Since we know A3 and the common ratio, we can substitute these values into the formula:

60 =\(A1 * (160/60)^(3-1)\)

Simplifying this equation, we have:

\(60 = A1 * (8/3)^260 = A1 * (64/9)\)

To isolate A1, we divide both sides of the equation by (64/9):

A1 = 60 / (64/9)

Simplifying further, we have:

A1 = 540/64 = 67.5/8.

Therefore, the first term of the sequence (A1) is 67.5/8.

Now that we know A1 and the common ratio, we can find Az using the formula:

Az = A1 * r^(z-1)

Substituting the values, we have:

Az =\((67.5/8) * (160/60)^(z-1)\)

However, we now have the formula to calculate it once we know the position z in the sequence.

The value of the expression is 1.766.

To simplify simply means to make anything easier. In mathematics, simplifying an equation, fraction, or problem means taking it and making it simpler. Calculations and problem-solving techniques simplify the issue. By eliminating all common factors from the numerator and denominator and putting the fraction in its simplest/lowest form, we can simplify fractions.

Given the expression,

2\(e^{3x}\) = 400

divide by 2 into both sides

\(e^{3x}\) =  400/2

\(e^{3x}\) = 200

converting the expression in form of a log,

ln(\(e^{3x}\))= ln(200)

log(aⁿ) = n log(a)

3x ln(e) = ln(200)  [ln(e) = 1 and ln(200) = 5.2931]

3x = 5.2931

a.) To increase the number of tickets sold, the theatre should serve 28 different flavours of ice cream.

b.) A single night's maximum ticket revenue for the theatre is $117,750.

a) The vertex of the quadratic function must be located in order to determine the number of ice cream flavours that will sell the most tickets.

\(S(n) = -5n^2 + 280n + 5.\) The vertex of a quadratic function in the form of \(f(x) = ax^2 + bx + c\) can be found using the formula x = -b / (2a).

In our case, a = -5 and b = 280. Plugging these values into the formula, we get

n = -280/( 2 *-5)

n = 280/ 10

n = 28

thus, the theater should offer 28 ice cream flavors to maximize the number of tickets vended.

b) To calculate the maximum ticket profit, we need to multiply the number of tickets vended by the price per ticket. In this case, the price per ticket is given as$ 30.

Using the value we set up in part a, where n = 28, we can substitute it into the function S( n) to find the number of tickets vended

\(S(28) = -5(28)^2 + 280(28) + 5\\S(28) = -5(784) + 7840 + 5\\S(28) = -3920 + 7840 + 5\\S(28) = 3925\)

So, the theater can vend a outside of 3925 tickets on a given night.

To calculate the maximum ticket profit, we multiply the number of tickets vended by the price per ticket

Ticket profit = Number of tickets vended * Price per ticket

Ticket profit = 3925 *$ 30

Ticket profit = $ 117,750

thus, the maximum ticket profit the theater can make on a given night is$ 117,750.

The 99% confidence interval for the true population mean backpack weight is approximately (68.15, 71.85) ounces, rounded to two decimal places.

To construct a 99% confidence interval for the true population mean backpack weight, we can use the formula:Confidence Interval = Sample Mean ± (Critical Value * Standard Deviation / √Sample Size).

Since the population standard deviation is known, we can use the z-distribution and find the critical value corresponding to a 99% confidence level. The critical value for a 99% confidence level is approximately 2.576.

Given that the sample mean weight is 70 ounces, the population standard deviation is 6.4 ounces, and the sample size is 48, we can calculate the confidence interval:

Confidence Interval = 70 ± (2.576 * 6.4 / √48).
