The area of the square is changing at 12√2 + 2√2t square inches/minute when the circle is increasing at 1 in/min.

Let us find the relationship between r and s using the Pythagorean theorem. Since the square is inscribed in the circle, the diameter of the circle is equal to the diagonal of the square.

2r = s√2
Squaring both sides, we get:
4r² = 2s²or s² = 2r²
Dividing by 2 on both sides, we get:
s²/2 = r²
Differentiating both sides with respect to t, we get:
ds²/dt = 2r (dr/dt)
Dividing both sides by 2s, we get:
ds/dt = r (dr/dt) / s

Substituting r² = s²/2,

\(ds/dt = r (dr/dt) / √2s2s ds/dt = r (dr/dt)s ds/dt = (r/2) (dr/dt)2s ds/dt = r (dr/dt) or dA/dt = 2s ds/dt = 2r (dr/dt)\)

Now, substituting r² = s²/2,

dA/dt = 2s ds/dt = 2(√2 s) (dr/dt) = 2(√2) r (dr/dt)

Now, substituting dr/dt = 1 in/min and r = 6 in (since the circle is increasing at 1 in/min, the radius after t minutes is 6 + t),

dA/dt = 2(√2) (6 + t) (1) = 12√2 + 2√2t square inches/minute

Therefore, the area of the square is changing at a rate of 12√2 + 2√2t square inches/minute.

In this case, since we want the sample mean to be within 0.01 of the population mean, the margin of error is 0.01.

To determine the number of grade-point averages needed to have a sample mean within 0.01 of the population mean, we can use the formula for the margin of error. The margin of error is calculated by dividing the standard deviation of the population by the square root of the sample size, multiplied by a constant value.

To find the required sample size, we need to know the standard deviation of the population. However, since it is not provided, we cannot calculate the exact number of grade-point averages needed.
If you have the standard deviation of the population, you can use the following formula to calculate the sample size:
Sample size = (Z * standard deviation) / margin of error

Where Z is the constant value that corresponds to the desired level of confidence. For example, if you want a 95% confidence level, Z would be approximately 1.96.

The measure of angles are

The length of the hypotenuse of the right triangle = 11 inches

The length of the one leg = 10 inches

Then the length of the other leg is the square root of the sum of the hypotenuse square and one leg square

Then the equation will be

The length of the other leg = \(\sqrt{11^2-10^2}\)

= \(\sqrt{121-100}\)

= 4.58 inches

Therefore AC = 11 inches

AB = 10 inches

BC = 4.58 inches

The angle B = 90 degrees

Consider the angle A

cos θ = Adjacent side / hypotenuse

cos θ = 10 /11

θ = 24.61 degrees

Consider the angle C

cos θ = Adjacent side / Hypotenuse

The required white effective interest rate is 0.71% more than his nominal interest rate.

Compound interest is the interest on deposits computed on both the initial principal and the interest earned over time.

Here,

White Effective interest R,

R = 14.33 percent

So

Difference in interest = 14.33%-13.62%

Approximately 46 adult tickets and 92 children tickets were sold during the recent showing at the movie theater.

To determine the number of adult and children tickets sold during a recent showing at the movie theater, where the ticket prices for adults and children are given, we can solve a system of equations based on the total number of tickets sold and the total revenue generated.

Let's assume the number of adult tickets sold is "a" and the number of children tickets sold is "c". Given that an adult ticket costs $7 and a children ticket costs $4.25, we can set up the following equations based on the total number of tickets sold and the total revenue generated:

Equation 1: a + c = 139 (equation representing the total number of tickets sold)

Equation 2: 7a + 4.25c = 720 (equation representing the total revenue generated)

To solve this system of equations, we can use substitution or elimination methods. Let's use the elimination method as an example:

Multiply Equation 1 by 4.25 to make the coefficients of "c" in both equations equal:

4.25a + 4.25c = 591.75

Subtract Equation 2 from the above equation:

(4.25a + 4.25c) - (7a + 4.25c) = 591.75 - 720

-2.75a = -128.25

Divide both sides of the equation by -2.75:

a = 46.8

Substitute the value of "a" back into Equation 1 to find "c":

46.8 + c = 139

c = 139 - 46.8

c = 92.2

Answer: The number is 15.

Step-by-step explanation: We are given a certain number we don't know about. Since it's value is unknown it is a variable. We'll call this variable "x". That number, x, is divided by 3, and then 3 was added to x to make 8. So then if x =  15, then dividing it by 3 would make 5, and adding 3 to that would make 8.

Another way to solve this, or check your work, is to work the problem out in reverse. Starting with the number 8, subtract 3 and then multiply that number by 3. This will give you the number 15. Which shows that the answer is correct.

\((\frac{15}{3}) + 3 = x\)

\(5+3= x\)

\(8=x\)

\(x=8\)

\(3(8-3) = x\)

\(3(5) = x\)

or

\(24 - 9 = x\)

\(15 = x\)

\(x=15\)

Thus the number is 15. Hope this helps, and have a great day!

Answer:

Answer: area= 38, perimeter=34

Step-by-step explanation: a=lw,p= sum of all sides

The area of the biggest, middle and smallest shapes are 14 cm²,16 cm², and 8 cm² respectively while the perimeter of the biggest, middle and smallest shapes are 18 cm,16cm, and 12 cm respectively.

Perimeter is the addition of an external measure of sides it will always positive.

A perimeter is a length and has a degree of the unit as one.

Perimeter of square = side + side + side + side

The given object is divided into three sections.

Biggest section :

Area = 2 x 7 = 14 cm²

Perimeter = 2(7 + 2) = 18 cm

Middle section :

Area = 4 x 4 = 16cm²

Perimeter = 2(4 + 4) = 16cm

Smallest section :

Area = 2 x 4 = 8 cm²

Perimeter = 2(2 + 4) = 12 cm

Hence "The area of the biggest, middle and smallest shapes are 14 cm²,16 cm², and 8 cm² respectively while the perimeter of the biggest, middle and smallest shapes are 18 cm,16cm, and 12 cm respectively".

The equation y = 0.15x allows us to model the relationship between the number of minutes and the price of a service or product that has a fixed cost per unit time.

The equation y = 0.15x represents a linear relationship between the two variables x and y, where y is the dependent variable (the price) and x is the independent variable (the number of minutes).

This equation tells us that for every additional minute (increase in x), the price (y) will increase by a fixed proportionality constant of 0.15, which is the slope of the line. In other words, if we plot the values of x and y on a coordinate plane, with minutes on the x-axis and price on the y-axis, then the line formed by the equation y = 0.15x will have a slope of 0.15.

For example, if a service charges $0.15 per minute, then the equation y = 0.15x can be used to calculate the total cost (y) of using the service for a certain number of minutes (x). If a customer uses the service for 30 minutes, then the total price would be:

y = 0.15 * 30 = $4.50

Similarly, if the customer uses the service for 45 minutes, then the total price would be:

y = 0.15 * 45 = $6.75

Thus, the equation y = 0.15x allows us to model the relationship between the number of minutes and the price of a service or product that has a fixed cost per unit time.

To determine the number of 9s between 1 and 100, we can consider the numbers from 1 to 99 since we want to exclude 100.

In the range from 1 to 99, we can observe the following patterns:

There is one 9 in each of the units' places (9, 19, 29, ..., 89, 99), giving us 10 occurrences.

There is one 9 in each of the tens' places (90, 91, 92, ..., 99), giving us 10 occurrences.
