The value of x from the given circle is 4.6 units.

From the given figure, the radius is 9.7 units.

A circle is a two-dimensional figure formed by a set of points that are at a constant or at a fixed distance (radius) from a fixed point (center) on the plane. The fixed point is called the origin or center of the circle and the fixed distance of the points from the origin is called the radius.

Here,

9.7 =5.1+x

⇒ x=9.7-5.1

⇒ x=4.6 units

Therefore, the value of x from the given circle is 4.6 units.

A percentage is a way to describe a part of a whole. The best option for the customer to buy is option A.

A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.

Let the cost price of a cereal box be represented by x.

Given that the box usually contains 450 grams of cereal. Therefore, the unit rate for each option can be written as,

Option A

Weight of cereal = 20% more cereal

= 450 grams + 20% of 450 grams

= 450 grams + 90 grams

= 540 grams

Unit rate for option A = $x / 540 grams

Option B

Cost price of cereal = 15% off the price

= x - 15% of x

= x + 0.15x

= 0.85x

Unit rate for option A = $0.85x / 450 grams

Assume that option A is good. Now, if we subtract unit rate of option B from unit rate of option A then two of the cases are possible, if the value of the result is positive then the unit rate of option A is bigger while if the value is negative unit rate of option B is bigger.

Difference = (x/540) - (0.85x/450)

= (450x - 459x)/243000

= -9x/243,000

= -x/27,000

Further, since the difference is negative, therefore, the unit rate of option B is bigger. But since the value of option B is bigger it is costly and not the correct option to buy.

Hence, the best option for the customer to buy is option A.

To answer the questions, we need to use the concepts of probability.

To answer the questions, we need to use the concepts of probability.

a. The number of airplanes arrive and depart the airport per hour can be calculated by multiplying the probabilities of a flight departing and arriving on time. Although the exact numbers are not given, the probability of a flight departing and arriving on time is 0.81, which can be used as an estimate.

b. To find the probability that there are exactly 100 arrivals and departures in one hour, we need to use the concept of the binomial distribution. However, we don't have enough information to calculate the probability.

c. To find the probability that there are at most 100 arrivals and departures in one hour, we can use the concept of the cumulative distribution function of the binomial distribution. Again, we don't have enough information to calculate the probability.

The question is about calculating probabilities and involves understanding conditional probability, probability distributions, and statistical methods. It requires more data to answer parts a, b, and c. The remaining parts of the question can be approached with standard statistical methods and concepts.

Final answer:

Using equivalent ratios is like adding fractions with unlike denominators as it involves finding a common value to work with.

Explanation:

Using equivalent ratios is similar to adding fractions with unlike denominators because both involve finding a common value to work with. When adding fractions, we look for a common denominator so that we can add the numerators. With equivalent ratios, we find a common multiplier to scale the ratios, which allows us to compare or combine the quantities represented by the ratios.

Here's a step-by-step process:

Convert the given ratios to fractions by writing them as a fraction with the given quantities as the numerator and denominator.

Find a common denominator for the fractions. This involves identifying the least common multiple (LCM) of the denominators.

Multiply the numerators and denominators of the fractions by the appropriate multiples to get equivalent fractions with the same denominator.

Compare or combine the quantities represented by the equivalent fractions.

Answer:

D)  $ 300

Step-by-step explanation:

Here, the cost ( in dollars ) of x products is defined by the function,

[tex]C=0.25x^2-80x+300[/tex]

Since, if the no units are produced,

x = 0,

Hence, the cost would be,

[tex]C=0.25(0)^2-80\times 0+300[/tex]

[tex]=0-0+300[/tex]

[tex]=\$ 300[/tex]

Option D is correct.

The cost is $300 if no units are produced.

To find the cost when no units are produced, which are shown by x and we need to evaluate the cost function C at x = 0. The cost function is given by [tex]C = 0.25x^2 - 80x + 300.[/tex]

Let's substitute x = 0 into the function:

[tex]C(0) = 0.25(0)^2 - 80(0) + 300[/tex]

[tex]C(0) = 0 - 0 + 300[/tex]

[tex]C(0) = 300[/tex]

Therefore, the cost when no units are produced is $300.

This corresponds to the constant term in the cost function, which represents the fixed costs that are incurred regardless of the number of units produced.

The baby meerkat weighs 29 grams.

First, we need to ensure our units are the same, so we'll convert 776 grams to kilograms.

There are 1,000 grams in a kilogram, so 776 grams is equivalent to 0.776 kilograms.

Given that the adult meerkat is 0.747 kilograms heavier than the baby meerkat, we can calculate the baby meerkat's weight by subtracting.

Baby meerkat weight = Adult meerkat weight - Additional weight

Baby meerkat weight = 0.776 kg - 0.747 kg

Baby meerkat weight = 0.029 kg

To express this in grams, we multiply by 1,000:

Baby meerkat weight in grams = 0.029 kg × 1000

= 29 grams

Shane and his family spent a total of $103 at the movie theatre, which includes the cost of 6 tickets at $12 each and $31 on popcorn and drinks.

Shane and his family bought 6 tickets for $12 each, thus the total cost of the tickets is 6 * $12 which equals $72. Afterwards, they spent an additional $31 on popcorn and drinks. To find out how much they spent altogether at the movie theatre, we have to add the cost of the tickets and the cost of the popcorn and drinks. Therefore, $72 (for the tickets) + $31 (for the snacks) = $103. So, Shane and his family spent a total of $103 at the movie theatre.

The solution to the equation 12^x - 2 = 20, when solved for x and rounded to the nearest ten-thousandth, is x = 1.4624.

To solve the equation 12^x - 2 = 20, we first need to isolate the exponential term. This can be done by adding 2 to both sides of the equation resulting in 12^x = 22. Next, we take the logarithm of both sides to solve for x. We can use any logarithmic base, but common practice is to use base 10 or the natural logarithm (base e). The next steps are:

Calculating the value on a calculator gives us x ≈ 1.4624. Therefore, the solution to the equation, rounded to the nearest ten-thousandth, is x = 1.4624.

The correct answer is option (b) "x ≈ 1.2056."

To solve the equation [tex]\(12^{(x-2)} = 20\)[/tex], we can take the logarithm of both sides.

Let's use the natural logarithm (ln) for this:

[tex]\[ \ln(12^{(x-2)}) = \ln(20) \][/tex]

Using the logarithm property [tex]\( \log_a(b^c) = c \cdot \log_a(b) \)[/tex], we can rewrite the left side:

[tex]\[ (x-2) \cdot \ln(12) = \ln(20) \][/tex]

Now, solve for (x):

[tex]\begin{aligned}& x-2=\frac{\ln (20)}{\ln (12)} \\& x=\frac{\ln (20)}{\ln (12)}+2\end{aligned}[/tex]

Now, calculate the value:

[tex]\begin{aligned}& x \approx \frac{\ln (20)}{\ln (12)}+2 \\& x \approx \frac{2.9957}{2.4849}+2 \\& x \approx 1.2056\end{aligned}[/tex]

So, the solution to the equation is approximately [tex]\( x \approx 1.2056 \)[/tex]

The diameter is increasing at a rate of approximately 100 / 300π cm/s when the radius is 5 cm.

To find the rate at which the diameter is increasing, we need to differentiate the formula for the volume of a sphere with respect to time:

V = (4/3)πr^3

Where V is the volume and r is the radius.

Let's differentiate V with respect to t:

dV/dt = (4/3)π(3r^2)(dr/dt)

We know dV/dt = 100 cm^3/s and r = 5 cm, so plug in these values:

100 = (4/3)π(3(5^2))(dr/dt)

Simplifying the equation gives us:

dr/dt = 100 / (4π(3(5^2)))

dr/dt ≈ 100 / 300π

So, the diameter is increasing at a rate of approximately 100 / 300π cm/s when the radius is 5 cm.
