16. Garrett can complete four laps around the
track in 7 minutes and 45 seconds. How
many full laps can he complete in 1 hour

Answers

Answer:

Step-by-step explanation:

45 seconds = 45/60 = 0.75 minutes

7 minutes 45 seconds = 7.75 minutes

One hour = 60 minutes

Number of full laps = 60/ 7.75 = 6000/775 = 7.74

A square wrestling mat has a perimeter of (12x−32)
feet. Write an expression in simplest form that represents the side length (in feet) of the mat.

Answers

Answer:

The perimeter of a square is given by the formula P = 4s, where s is the side length. In this case, we are given that the perimeter is (12x - 32) feet, so we can set up an equation:

P = 4s

(12x - 32) = 4s

To solve for s, we can divide both sides by 4:

(12x - 32)/4 = s

Simplifying the expression on the left:

3x - 8 = s

Therefore, the expression in simplest form that represents the side length of the square wrestling mat is 3x - 8 feet.

how many solutions does the eqaution below have? 4x-3-2x+5=6-3x+2+5x

Answers

Answer:

4x - 3 - 2x + 5 = 6 - 3x + 2 + 5x

2x + 2 = 2x + 8

2 ≠ 8, so this equation has no solutions.

Answer:

No solution

Step-by-step explanation:

Given:

\(4x-3-2x+5=6-3x+2+5x\)

rearrange terms so like terms are together

\(4x-2x-3+5=6+2-3x+5x\)

combine like terms

\(2x+2=8+2x\)

subtract 2x to both sides

\(2\neq 8\)

2 doesn't equal 8, meaning that there are 0 solutions to this problem.

What are the intercepts and asymptote of h(x)? Explain how to find these using the graph.

Answers

The intercepts of h(x) are (-1, 0), (4, 0), and (0, 4), and the asymptotes are x = 2 and y = 3. To find these intercepts and asymptotes using the graph, we need to look for the points where the graph intersects the x-axis and the y-axis, and where the function approaches infinity or a constant value as x approaches certain values.


From the graph, we can see that the function h(x) has a vertical asymptotes at x = 2, which means that as x approaches 2 from either side, the function approaches positive or negative infinity. We can also see that the function has a horizontal asymptote at y = 3, which means that as x approaches positive or negative infinity, the function approaches 3. To find the intercepts of h(x), we need to look for the points where the graph intersects the x-axis and the y-axis. From the graph, we can see that the function intersects the x-axis at x = -1 and x = 4, which means that these are the x-intercepts. The function intersects the y-axis at y = 4, which means that this is the y-intercept.

Using the Pythagorean Theorem, we know x^2 + 46^2 is equal to 65^2. With that in mind, it is important to note:

65^2 = 4,225
46^2 = 2,116

To find the missing angle, we must subtract 2,116 from 4,225 and then identify the difference’s square root.

4,225 - 2,116 = 2,109

what's the inverse of f(x)=(x+3)^5

Answers

Answer:

The inverse is,

\(f^{-1}(x) = \sqrt[5]{x} - 3\)

Step-by-step explanation:

f(x) = (x+3)^5

Finding the inverse,

\(f(x) = (x+3)^5\\or,\\y = (x+3)^5\)

We replace x with y and vice versa

so,

\(x = (y+3)^5\)

Solving for y,

the the 5th root,

\(\sqrt[5]{x} = y + 3\\y = \sqrt[5]{x} - 3\)

hence the inverse function is,

\(f^{-1}(x) = \sqrt[5]{x} - 3\)

Step-by-step explanation:

f(x)=(x+3)×5

Y=5X+15

now

interxchanging x and y we get,

x=5y+15

5y=x-15

y=x-15/5

therefor f~1(x)=x-15/5

A fraction is usually split into two parts: the first part is the number on top, called the numerator; and the second part is the number on the bottom, called the denominator. These are both separated by a line called the “divisor line”. We can use the division method help to solve this question: to get a decimal, simply divide the numerator 54 by the denominator 7 (which you can enter in any calculator):

54 (numerator) ÷ 7 (denominator) = 7.71

And finally, you get 7.71 as your answer when you convert 7 5/7 (or 54/7) to a decimal.

A rhombus where the left side of the horizontal diagonal has length 10 and the right side of the horizontal diagonal has length 10. The top of the vertical diagonal has length 6 and the bottom of the vertical diagonal has length 6.
What is the area of the rhombus?


square units

Answers

Answer:

120 square units

-----------------------------

The horizontal diagonal is:

h = 10*2 = 20 units

The vertical diagonal is:

v = 6*2 = 12 units

The area of a rhombus is half the product of its diagonals:

A = vh/2

Find the area of the given rhombus:

A = 20*12/2A = 120 square units

Answer:

30 units

Step-by-step explanation:

To find the area of a rhombus, you can use the formula:

Area = (diagonal 1 × diagonal 2) / 2

In this case, the horizontal diagonal has a length of 10 on the left and 10 on the right sides. The vertical diagonal has a length of 6 on the top and 6 on the bottom.

Plugging in the values into the formula:

Area = (10 × 6) / 2

Simplifying the expression:

Area = 60 / 2

Area = 30 units²

Therefore, the area of the rhombus is 30 square units.

At an amusement park, riders must be at least 48 inches tall to ride the Night Eagle roller coaster. Keenan has grown 1.5 inches since last summer, but he is still too short to ride. Let x represent how tall Keenan was last summer. Which inequality describes the problem?

Answers

The inequality that describes the given word problem is;

x + 1.5 < 48

How to solve Inequality word problems?

Let x represent how tall Keenan was last summer. Thus;

x = Keenan's height last summer in inches

If he was x inches last summer, and has since grown an additional 1.5 inches up to date, then it means that his total height now is;

x + 1.5 inches.

The conditons state "riders must be at least 48 inches tall to ride the Night Eagle roller coaster". So it means that his height must be equal to 48 inches, or larger than 48 inches, to make him eligible to ride the roller coaster.

But since he is still too short to ride, this means the expression x+1.5 is smaller than 48 and as such the inequality of this problem is;

x + 1.5 < 48

two people are selected at random from a group of 16 republicans and 19 democrats. find the probability of each of the following. (round your answers to three decimal places.)

Answers

The probability of both people being Democrats is 0.243, and the probability of one person being a Republican and one person being a Democrat is 0.486.

To find the probability of each of the following, we can use the formula for the probability of selecting a group of items from a larger group with replacement:

P(A and B) = P(A) * P(B)

Where P(A) is the probability of selecting the first item, and P(B) is the probability of selecting the second item.

Both people are Democrats:

There are 16 Democrats and 31 total people, so the probability of selecting a Democrat is 16/31. Therefore, the probability of selecting two Democrats is (16/31) * (16/31) = 0.243.

One person is a Republican and one person is a Democrat:

There are 15 Republicans and 31 total people, so the probability of selecting a Republican is 15/31. There are 16 Democrats and 31 total people, so the probability of selecting a Democrat is 16/31. Therefore, the probability of selecting one Republican and one Democrat is (15/31) * (16/31) = 0.486.

Ali, Basti and Cian stand at three points A, B and C respectively. Suppose that the measure of angle ABC is 50 degrees , the measure of angle BAC is 60 degrees and Ali is exactly 150 ft away from Basti. Find the distance between Basti and Cian.

Answers

To find the distance between Basti and Cian, we can use the law of sines in triangle ABC. The law of sines states that the ratio of the length of a side to the sine of the opposite angle is constant for all sides and their corresponding angles in a triangle.

Let's label the distance between Basti and Cian as "x". We know that the measure of angle ABC is 50 degrees and the measure of angle BAC is 60 degrees. We also know that Ali is exactly 150 ft away from Basti.

Using the law of sines, we can set up the following equation:

sin(50°) / 150 = sin(60°) / x

To solve for "x", we can rearrange the equation:

x = (150 * sin(60°)) / sin(50°)

Using a calculator, we can evaluate the expression:

x ≈ (150 * 0.866) / 0.766

x ≈ 168.4 ft

Therefore, the distance between Basti and Cian is approximately 168.4 ft.

Jevonte mowed 6 lawns in 4 hours. What was his rate of mowing in lawns per hour?

Answers

Jevonte's rate of mowing is 1.5 lawns per hour.

How do rates work?

A rate in mathematics is an indicator of how one quantity has changed in relation to another, usually given as a ratio or fraction. Rates are frequently used to explain the relationship between two quantities as they vary through time, space, or another variable. For instance, whereas interest rates track the evolution of money over time, speed tracks the change in distance per unit of time. Rates are used to describe and study numerous phenomena in several disciplines, including physics, economics, and finance.

Given that, Jevonte mowed 6 lawns in 4 hours.

Thus,

Rate of mowing = Number of lawns / Number of hours

Rate of mowing = 6 lawns / 4 hours

Rate of mowing = 1.5 lawns per hour

Hence, Jevonte's rate of mowing is 1.5 lawns per hour.
