Answer:

6 feet per minute.

Step-by-step explanation:

The turtle and snail are moving towards each other, so their speeds add up. Therefore, the combined speed at which they approach each other is:

5 feet/min (turtle's speed) + 1 feet/min (snail's speed) = 6 feet/min

Therefore, the turtle and snail are approaching each other at a speed of 6 feet per minute.

Answer:

6 feet per minute.

Using the concept of the word problem and utilizing the provided conditions and values, The answer is 18, 20, and 22.

A word problem in mathematics is a problem or exercise that is expressed in a natural language, rather than in mathematical notation. These types of problems often present a real-world situation that involves mathematical concepts, such as numbers, operations, or measurements. They typically require the use of mathematical reasoning and problem-solving skills to understand the problem and find a solution. Examples of word problems include: "If a train travels 60 miles per hour and you want to know how far it will travel in 4 hours", "If a rectangle is 6 meters long and 4 meters wide, what is its area?", "If a bag contains 3 red balls and 4 blue balls, what is the probability of picking a blue ball?"

In a mathematical problem, the conditions refer to the specific information or constraints provided in the problem statement that must be taken into account in order to find a solution. These conditions can include information about the quantities involved in the problem, the operations that need to be performed, or the specific requirements that the solution must meet.

Let x be the smallest of the three consecutive even integers. Then the next two integers are x+2 and x+4. We know that:

x + (x+4) * 3 = 84

Expanding and solving for x:

x + 3x + 12 = 84

4x = 72

x = 18

So the three consecutive even integers are 18, 20, and 22.

Answer:yes

Step-by-step explanation:

Yes, you are far enough away from your competitor whose distance is 5.31 miles.

Pythagoras theorem states that in a right-angled triangle, the square of one side is equal to the sum of the squares of the other two sides.

A right triangle is defined as a triangle in which one angle is a right angle or two sides are perpendicular.

You plan to be at least 5 miles (straight line distance) from your competitor

Here the two legs of a right triangle are 4 miles and 3.5 miles.

According to Pythagoras theorem,

So straight line distance from your competitor would be:

= √(4² + 3.5²)

= √(16 + 12.25)

= √(28.25)

= 5.31 miles

Therefore, you are far enough away from your competitor whose distance is 5.31 miles.

P(1.6,-2.9) are the coordinates of circumcentre of the triangle

The circumcenter of a triangle is the point where the perpendicular bisectors of the sides of that particular triangle intersect.

Let L(3,−6), M(5,−3), N(8,−6) be the vertices of the given △LMN.

Let P(x,y) be the circumcentre of △LMN. Then,

PL = PM = PN

Also, PL² = PM² = PN²

PL² = PM²

(x-3)² + (y-(-6))² = (x-5)² + (y-(-3))²

(x-3)² + (y+6)² = (x-5)² + (y+3)²

x²-6x+9 + y²+12y+36 = x²-10x+25 + y²+6y+9

4x + 6y = -11   ---- (1)

Also, PM² = PN²

(x-5)² + (y-(-3))² = (x-8)² + (y-(-6))²

(x-5)² + (y+3)² = (x-8)² + (y+6)²

x²-10x+25 + y²+6y+9 = x²-16x+64 + y²+12y+36

6x - 6y = 27   ---- (2)

Solve (1) and (2) simultaneously by elimination:

6 × (4x + 6x = -11)

4 × (6x - 6y = 27)

24x + 36y = -66

24x - 24y = 108

subtract:

         60y = -174

         y = -174/60

         y = -2.9

Put y = -2.9 into (1):

4x + 6x = -11

4x + 6(-2.9) = -11

4x - 17.4 = -11

4x = 6.4

x = 1.6

Thus, the coordinates of the circumcentre of △LMN are P(1.6, -2.9)

Answer:

P(B|A') = 7/15

Step-by-step explanation:

P(B) = 0.2

P(A|B) = 0.3

P(A|B)=P(A and B) / P(B)

0.3=P(A and B) / 0.2

P(A and B)=0.06

P(B') = 1 - P(B) = 1 - 0.2 = 0.8

P(A|B') = 0.8

P(A|B')=P(A and B') / P(B')

0.8 = P(A and B') / 0.8

P(A and B') = 0.64

P(A)=P(A and B) + P(A and B')=0.06+0.64=0.7

P(A')=1-P(A)=1-0.7=0.3

P(A' and B) + P(A and B) = P(B)

P(A' and B) = P(B) - P(A and B)

P(A' and B) = 0.2 - 0.06 = 0.14

P(B|A') = P(A' and B) / P(A')

P(B|A') = 0.14 / 0.3 = 7/15

Answer:

To find the total distance, we need to add up the distance the student ran in the first 5 days and the distance the student ran in the next 5 days.

Distance for the first 5 days = 3 1/2 miles/day × 5 days = 17.5 miles

Distance for the next 5 days = 4 1/4 miles/day × 5 days = 21.25 miles

Total distance = Distance for the first 5 days + Distance for the next 5 days

Total distance = 17.5 miles + 21.25 miles

Total distance = 38.75 miles

Therefore, the student ran a total of 38.75 miles during these 10 days.

Answer:

0.1490 = 14.90% probability that a randomly selected potential customer will purchase the product.

Step-by-step explanation:

Probability of seeing the ad:

I am going to find this probability using Venn Sets.

I am going to say that:

Event A: Sees a magazine ad.

Event B: Sees a television ad.

Approximately 1 in 50 potential buyers of a product sees a given magazine ad

This means that \(P(A) = \frac{1}{50} = 0.02\)

1 in 5 sees a corresponding ad on television.

This means that \(P(B) = \frac{1}{5} = 0.2\)

One in 100 see both.

This means that \(P(A \cap B) = \frac{1}{100} = 0.01\)

The probability of seeing the ad is the probability of seeing at least one of those(magazine or tv), which is:

\(P(A \cup B) = P(A) + P(B) - P(A \cap B)\). So

\(P(A \cup B) = 0.2 + 0.02 - 0.01\)

\(P(A \cup B) = 0.21\)

Probability of purchasing the product.

0.21 = 21% of customers see the add. Of those, 1/3 = 0.3333 buy the product.

1 - 0.21 = 0.79 = 79% of customers dont see the add. Of those, 1/10 = 0.1 buy the product. So

\(p= 0.21*0.3333 + 0.79*0.1 = 0.1490\)

0.1490 = 14.90% probability that a randomly selected potential customer will purchase the product.

Answer:

The football is approximately 96.4 feet from the base of the goal post.

The tangent function in trigonometry is used to determine the proportion between the lengths of the adjacent and opposite sides in a right triangle. Where theta is the angle of interest, the tangent function is defined as:

tan(theta) = opposing / adjacent.

When the lengths of one side and one acute angle are known, the tangent function is used to solve for the unknown lengths or angles in right triangles. In order to utilise the tangent function, we must first determine the angle of interest, name the triangle's adjacent and opposite sides in relation to that angle, and then calculate the ratio of those sides using the tangent function.

Given, the angle of elevation is 16 degrees 42'.

That is,

Angle of elevation = 16 degrees 42' = 16 + 42/60 = 16.7 degrees

Using tangent function we have:

tan(16.7) = 30/x

x = 30 / tan(16.7)

x = 96.4 feet

Hence, the football is approximately 96.4 feet from the base of the goal post.

a) The definition of the composite function is: \((f \circ g)(x) = \frac{6}{12 + 2x}\)

b) The domain of the composite function is: (-∞, -6) U (-6, -2) U (-2,0) U (0, ∞).

The composite function of f(x) and g(x) is given by the function rule presented as follows:

(f ∘ g)(x) = f(g(x)).

For the composition of two functions, we have that the output of the inner function, which in this example is given by g(x), serves as the input of the outer function, which in this example is given by f(x).

The functions for this problem are given as follows:

Hence the composite function is obtained as follows:

\((f \circ g)(x) = f(\left\frac{6}{x}\right)\)

\((f \circ g)(x) = \frac{\frac{6}{x}}{\frac{6}{x} + 2}\)

\((f \circ g)(x) = \frac{\frac{6}{x}}{\frac{12 + 2x}{x}}\)

\((f \circ g)(x) = \frac{6}{12 + 2x}\)

The domain is all real values except x = 0, x = -2 and x = -6, as f(x) is not defined at x = -2 and g(x) is not defined at x = 0 and the composite function is not defined at x = -6, hence the interval notation is:

The amount of money for selling 450 baked goods will be

Any relationship that is always in the same ratio and quantity which vary directly with each other is called the proportional.

Given that;

At a bake sale, the Math Club raised $225 by selling 300 baked goods.

And, The amount raised varies directly with the baked goods sold.

Now,

Let the amount of money for selling 450 baked goods = x

Since, At a bake sale, the Math Club raised $225 by selling 300 baked goods.

And, The amount raised varies directly with the baked goods sold.

Hence, By definition of proportion we get;

⇒ $225/300 = x / 450

⇒ x = 225 × 450 / 300

⇒ x = $337.5
