Final answer:

The small business owner's profit for a ten-day period is $4,675, calculated by determining the total daily revenue from pizza slices and sandwiches, subtracting daily expenses, and then multiplying the result by ten.

Explanation:

The question pertains to calculating the profit for a small business over a ten-day period. To do this, we first calculate the daily revenue from selling pizza slices and sandwiches and then subtract the daily expenses. After that, we multiply the daily profit by ten.

The owner's profit for the ten-day period would then be $4,675.

Hence, it will take 4.71 minutes  for all the liquid in the funnel to pass through the nozzle.

A cone shaped funnel has a radius(r) of 3 inches and a height(h) of 7 inches.

Now, the volume(V) of the cone is given as:

[tex]V=\dfrac{1}{3}\times (\pi r^2h)[/tex]

Hence, on putting the value of r and h in the formula of volume we obtain the volume of cone funnel as:

[tex]V=\dfrac{1}{3}\times (3.14\times (3)^2\times 7)\\\\\\V=\dfrac{1}{3}\times (197.82)\\\\V=65.94 \ in^3[/tex]

If the liquid drips at the rate of 14 cubic inches per minute.

i.e. for 14 cubic inches it takes 1 minutes.

Now for 1 cubic inches it will take:

[tex]\dfrac{1}{14} \ min.[/tex]

Hence, for all the liquid ( i.e. 65.94 cubic inches) to pass the nozzle is the time taken is:

[tex]\dfrac{65.94}{14}\ min.\\\\=4.71\ min.[/tex]

Hence, it will take 4.71 minutes  for all the liquid in the funnel to pass through the nozzle.

there are 4 Aces and 4 8's for a total of 8 cards

52 cards in a deck

 so probability of picking an Ace or 8 = 8/52

Final answer:

The probability of being dealt an ace or an 8 from a standard 52-card deck is 2/13, which is approximately 15.38%.

Explanation:

The question asks for the probability of being dealt an ace or an 8 from a standard 52-card deck. There are 4 aces and 4 eights in a 52-card deck. To calculate the probability of getting either an ace or an 8, we add the probability of getting an ace to the probability of getting an 8. The probability of drawing an ace (P(Ace)) is 4/52 and the probability of drawing an 8 (P(8)) is also 4/52. Since these are mutually exclusive events (you cannot draw an ace and an 8 simultaneously with one card), we can simply add these probabilities together:

P(Ace or 8) = P(Ace) + P(8)
= (4/52) + (4/52)
= 8/52
= 2/13

Therefore, the probability of being dealt an ace or an 8 is 2/13, which is approximately 0.1538 or 15.38%.

Final answer:

The student needs to solve a quadratic equation to find the base and height of a triangle using the area formula and the given relationship between height and base. The solution involves substitution, expansion, and application of the quadratic formula or factoring.

Explanation:

The problem involves finding the base and height of a triangular front of an A-frame cabin based on its given area and a relationship between the height and base. It's a typical quadratic equation problem found in the high school mathematics curriculum when dealing with geometry and algebra.

To find the base (b) and height (h) of the triangle, we first use the area formula of a triangle A = 1/2 × base × height. We know that the area (A) is 189 ft² and that the height (h) is 1 foot less than twice the base, so h = 2b - 1. Substituting h into the area formula, we get 189 = 1/2 × b × (2b - 1). Solving this quadratic equation, we find the values for the base (b) and substitute back to find the height (h).

The process entails expanding the equation, moving all terms to one side to set the equation to zero, and then using the quadratic formula or factoring to find the value of b. Once the base is found, we use the relationship h = 2b - 1 to determine the height.

Based on the pattern observed in the given equations, 13 + 13 would equal 8.

The given equations seem to follow a pattern where the sum of two numbers is not their arithmetic sum but rather a result derived from some other relationship. Let's try to decipher the pattern:

For the equation 11 + 11 = 4:

  The word "eleven" has 6 letters, so it becomes 6 + 6 = 4, which is true.

For the equation 12 + 12 = 9:

  The word "twelve" has 6 letters, so it becomes 6 + 6 = 9, which is true.

Following the same pattern:

For 13 + 13:

  The word "thirteen" has 8 letters, so it becomes 8 + 8 = ?

Thus, 13 + 13 = 8.

Therefore, based on the pattern observed in the given equations, 13 + 13 would equal 8.

The probable question maybe:

If 11 + 11 = 4 and 12 + 12 = 9 then what is 13 + 13 = ?

Answer: 6 sq. units

Step-by-step explanation:

The formula to find the circumference of a circle is given by :-

[tex]C=2\pi r[/tex], where r is the radius of the circle.

Given : Circumference = 10 units

Then , [tex]10=2\pi r[/tex]

[tex]\\\\\Rightarrow\ r=\dfrac{10}{2\pi}\approx1.59[/tex]

The area of a circle is given by :-

[tex]A=\pi r^2=\pi(1.59)^2=7.9422603875\approx7.94\text{ sq. units}[/tex]

Now, the 75 % of the area is given by :-

[tex]0.75\times7.94=5.955\approx6\text{ sq. units}[/tex]

Hence, 75% of the area of a circle with a circumference of 10 units = 6 sq. units

The irrational number among the options is root 3 + 8.486. option C.

An irrational number is a number that cannot be expressed as a fraction of two integers and has a non-repeating, non-terminating decimal expansion.

Let's examine each option:

A. [tex]\(7.51\ldots \times -4\)[/tex]

This is a rational number because it's the product of a rational number [tex](\(7.51\ldots\)) and \(-4\),[/tex] which is also rational. So, option A is not irrational.

B. [tex]\(\sqrt{16} + \frac{3}{4}\)[/tex]

[tex]\(\sqrt{16} = 4\)[/tex], so this expression simplifies to [tex]\(4 + \frac{3}{4}\)[/tex], which is a rational number. So, option B is not irrational.

C. [tex]\(\sqrt{3} + 8.486\)[/tex]

If [tex]\(\sqrt{3}\)[/tex] is not exactly equal to 8.486 , then this expression is irrational because it's the sum of an irrational number and a rational number. However, if [tex]\(\sqrt{3}\)[/tex] does happen to be exactly 8.486, then this expression would be rational. To determine if [tex]\(\sqrt{3}\)[/tex] is exactly 8.486, we need to compute [tex]\(\sqrt{3}\).[/tex] Since [tex]\(\sqrt{3}\)[/tex] is irrational (it's not a perfect square), 8.486 is not [tex]\(\sqrt{3}\)[/tex], so this expression is irrational. Therefore, option C is the correct answer.

D.[tex]\(8 \frac{2}{3} \times 17.75\)[/tex]

This is a rational number because it's the product of a rational number [tex](\(8 \frac{2}{3}\)) and \(17.75\),[/tex] which is also rational. So, option D is not irrational.

Complete question: Which of the following is irrational?

A. 7.51... x -4

B. root 16 + 3/4

C. root 3 + 8.486

D. 8 2/3 x 17.75

Answer:

[tex]s=4[/tex].

Step-by-step explanation:

We have been given an equation [tex]3r=10+5s[/tex]. We are asked to find the value of 's', when [tex]r=10[/tex].

To find value of 's', we will substitute [tex]r=10[/tex] in our given equation as shown below:

[tex]3(10)=10+5s[/tex]

[tex]30=10+5s[/tex]

Upon subtracting 10 from both sides of our given equation, we will get:

[tex]30-10=10-10+5s[/tex]

[tex]20=5s[/tex]

Now, we will divide both sides of our equation by 5.

[tex]\frac{20}{5}=\frac{5s}{5}[/tex]

[tex]4=s[/tex]

Therefore, the value of 's' is 4, when [tex]r=10[/tex].

To calculate the total fraction of tickets sold for the movie Fist Bump by Thursday, we find the least common denominator for the fractions (21), convert each fraction, and then sum them up to get 16/21 of the tickets sold.

The question is asking how much of the tickets were sold by Thursday for the movie Fist Bump. To find the total fraction of tickets sold from Monday to Wednesday, we need to add up the fractions:

First, let's find a common denominator for the fractions. The least common multiple of 7 and 3 is 21, so we'll convert all fractions to have a denominator of 21:

Now we can add the fractions:

3/21 + 7/21 + 6/21 = 16/21

Therefore, by Thursday, a total of 16/21 of the tickets have been sold.

Answer:

[tex]N=0[/tex]

Step-by-step explanation:

We have been given that a number N is multiplied by 3. So our number would be [tex]3\cdot N[/tex].

We are also told that N is divided by 3. So our number would be [tex]\frac{N}{3}[/tex].

As we are told that the both results are same, so we can equate both expressions as:

[tex]3\cdot N=\frac{N}{3}[/tex]

[tex]3*3\cdot N=\frac{N}{3}*3[/tex]

[tex]9N=N[/tex]

[tex]9N-N=N-N[/tex]

[tex]8N=0[/tex]

[tex]\frac{8N}{N}=\frac{0}{N}[/tex]

[tex]N=0[/tex]

Therefore, the value of N is 0.
