The wheel having 3feet diameter and travelling a distance of 45 feet is rotated about 30.00 radians.

A circle's circumference is equivalent to π times its diameter.

We can use the circumference formula to determine the circumference of the wheel

C = πd= π(3) = 9.42 feet where d is the diameter.

The wheel has traveled a distance of 45 feet.

We can determine the number of full rotations made by dividing the distance traveled by the circumference of the wheel.

Number of full rotations = distance traveled / circumference of the wheel= 45 / 9.42 = 4.77 full rotations

It is said that the wheel rolled without slipping, therefore the wheel must have turned 4.77 full rotations. The angle in radians through which it rotated is therefore

Angle in radians = number of full rotations x 2π= 4.77 x 2π= 30.00 radians

Therefore, the wheel rotated through a radian angle of 30.00.

The cost of the concrete used to make the cylinder was approximately $6,776.89.

The problem is asking us to find the cost of the concrete used to make a cylindrical pillar, given its dimensions and the cost per cubic meter of concrete. We first need to calculate the volume of the cylinder using the formula for the volume of a cylinder:

[tex]V=pir^2h[/tex]

where V is the volume, r is the radius, h is the height, and π is the constant pi (approximately 3.14159).

In the problem, the diameter of the cylinder is given as 4 meters, which means the radius is half of that, or 2 meters. The height of the cylinder is given as 5 meters.

Substituting these values into the formula, we get:

[tex]V = \pi r^2h = \pi (2)^2(5) = 20\pi cubic meters[/tex]

Next, we need to find the cost of the concrete used to make the cylinder, given that the cost per cubic meter of concrete is $107. We can do this by multiplying the volume of the cylinder by the cost per cubic meter of concrete:

20π × $107 = $6,776.89

Rounding to the nearest cent, we get that the cost of the concrete used to make the cylinder was approximately $6,776.89.

In mathematics, an equation is a statement that asserts the equality of two expressions. It consists of variables, constants, and mathematical operators such as addition, subtraction, multiplication, and division. An equation is usually written with an equal sign (=) between the two expressions. Equations are used to represent mathematical relationships between quantities, to solve problems, and to model real-world situations. They can be used to find unknown values, to predict outcomes, and to test hypotheses. There are many types of equations, including linear equations, quadratic equations, polynomial equations, trigonometric equations, and differential equations. Each type of equation has its own rules and methods for solving it.

QR has a length of 2√3. According to the given question

HOW TO CALCULATE THE SIDE OF THE SQUARE ?

In order to solve for QR, we need to use the information given to us in the problem and apply some basic geometry concepts.

First, we know that the diagonals of a square are perpendicular bisectors of each other, meaning they intersect at a 90-degree angle and divide each other in half. This tells us that the length of the diagonal is equal to the square root of two times the length of one of the sides of the square, or d = s√2.

Next, we are given that the midpoint of one of the diagonals is point U, and that US has a length of 3. Because U is the midpoint of the diagonal, we know that SU and UR are equal in length. Let's call this length x.

Now we can use the Pythagorean theorem to solve for x:

(US)²+ (UR)² = (SR)²

3²+  x= (s√2)²

9 + x² = 2s²

We also know that SU and UR are each equal to x, so:

2x² = s²

We can substitute 2x² for s² in the previous equation:

9 + x² = 2(2x²)

9 + x²= 4x²

3x² = 9

x² = 3

x = √3

Now we can use x to solve for the length of QR:

QR = 2x = 2√3

Therefore, QR has a length of 2√3.

Answer:

Step-by-step explanation:

c+ h = -4.20 (hours) + 49.20 shows how much jasmine earns (c) for working (h) hours

Let's assume that Jasmine earns at a constant rate per hour of work. We can use the formula for the equation of a line, y = mₓ + b, where y represents the amount of money earned, x represents the number of hours worked, m represents the rate of earnings per hour, and b represents the y-intercept or the amount of money earned without working. We can use the two points given in the problem to find the slope, m, of the line:

m = (y₂ - y₁) / (x₂ - x₁)

m = (16.80 - 25.20) / (4 - 6)

m = -4.20

Now that we know the slope, we can use either point and the slope to find the y-intercept, b:

y = mₓ + b

25.20 = -4.20 × (6) + b

b = 49.20

Therefore, the equation that represents Jasmine's earnings is:

c + h = -4.20 hours + 49.20

This function shows how much Jasmine earns, c, for working h hours.

(c) 22% of the values are less than x: x = 287.09

(d) x is greater than 57% of the values: x = 259.26

(a) To calculate x, we need to find the z-score of the 70th percentile. This can be done using the z-score formula: z = (x-mean)/standard deviation. Plugging in our values, this gives us z = (x-250)/44. Solving for x, we get x = 250 + 44z. We can find z by using a z-score table and looking up the 70th percentile, which is 0.84. Plugging this into our equation yields x = 233.43.

(b) Similarly, for x to be less than 14% of the values, we need to find the z-score of the 14th percentile. Looking up the corresponding z-score in a z-score table, we find it to be -0.91. Plugging this into our equation gives us x = 313.32.

(c) To calculate x given that 22% of the values are less than x, we can again use the z-score formula. This time, we need to look up the z-score corresponding to the 22nd percentile, which is -0.52. Plugging this into our equation yields x = 287.09.

(d) Lastly, to calculate x given that it is greater than 57% of the values, we need to find the z-score of the 57th percentile. Looking up the corresponding z-score in a z-score table, we find it to be 0.41. Plugging this into our equation gives us x = 259.26.

The hypotenuse's length could therefore be between 9.03 and 10.70 units based on these estimates.

The term "right triangle" refers to a triangle with an internal angle of 90 degrees. The hypotenuse, the side that faces the right angle and is also the side with the longest side in a right triangle, and the height and base are the two limbs of the right angle.

Based on the information provided, it is reasonable to infer that we have a right-angled triangle with two sides that are y and 7, and we need to determine the length of the hypotenuse.

The hypotenuse's square length is equal to the total of the squares of the lengths of the other two sides, according to the Pythagorean theorem.

The result is:

y² + 7² = hypotenuse²

hypotenuse² = y² + 49

we can determine the length of the hypotenuse by assuming that y is somewhere between 5.7 and 8.1.

If y is 5.7, then:

hypotenuse² = 5.7² + 49

hypotenuse² = 81.49

hypotenuse ≈ 9.03

If  y is 8.1, then:

hypotenuse² = 8.1² + 49

hypotenuse² = 114.61

hypotenuse ≈ 10.70

So, based on these estimations, the length of the hypotenuse could be around 9.03 or 10.70 units.

by the question.

First, we need to calculate the total fee the attorney will earn based on the hourly rate and the percentage of the settlement.

The attorney's fee is the sum of the hourly fee and the percentage of the settlement:

hourly fee = 110 hours x $175 per hour = $19,250

percentage of the settlement = 25% of the settlement

total fee = hourly fee + percentage of the settlement

We know that the total fee must be greater than or equal to $45,000, so we can set up an equation to solve for the minimum acceptable settlement:

$19,250 + 0.25S ≥ $45,000

where S is the settlement amount.

Subtracting $19,250 from both sides, we get:

Step-by-step explanation:

Since Shen drove at the same rate for both distances, we can use a proportion to solve for the time it would take him to drive 335 miles:

[tex]\frac{d_{1} }{t_{1} }=\frac{d_{2} }{t_{2} }[/tex]

where d1 is 603 miles, t1 is 9 hours, d2 is 335, and t2 is the unknown value.

Thus, we can simply plug in everything to the equation and solve for t2:

[tex]\frac{603}{9}=\frac{335}{t_{2} }\\ 67=\frac{335}{t_{2} }\\ 67t_{2}=335\\ t_{2}=5[/tex]

(*Note that 9 divides evenly into 603 and becomes 67, which is why I didn't cross-multiply first with he 603 and t2 and the 335 and 9, although you'd still get the same result for t2)

Thus, it would take Shen 5 hours to drive 335 miles.

You can check by finding the rate for both equations since we know that distance is equal to the product of rate and time (d = rt):

First equation:  603 miles = 9 hours * r mph

67 mph = r

603 = 67 * 9

Second equation: 335 miles = 5 hr * r mph

67 mph = r

335 = 67 * 5

The probability that in a random sample of 7 adults, exactly 2 will say they did not visit their physicians' offices last year is 0.287

This problem can be solved using the binomial distribution, which models the number of successes in a fixed number of independent trials with the same probability of success.

Let's define the following

n = 7 (the number of trials, i.e. the number of adults in the random sample)

p = 0.32 (the probability of success, i.e. the proportion of adults who did not visit their physicians' offices last year)

x = 2 (the number of successes we want to calculate the probability for)

The probability of exactly 2 successes in a binomial distribution is given by the formula

P(X = x) = nCx × p^x × (1-p)^(n-x)

where nCx is the number of ways to choose x items from a set of n items, and is given by the formula

nCx = n! / (x! × (n-x)!)

Plugging in the values, we get

nCx = 7! / (2! × 5!) = 21

P(X = 2) = 21 × 0.32^2 × (1-0.32)^(7-2) = 0.287

The sum of (8a + 2b - 4) and (3b - 5) is (8a + 5b - 9). We can find it in the following manner.

To find the sum of (8a + 2b - 4) and (3b - 5), we can simply add the corresponding coefficients of the variables a and b, as well as any constant terms.

So we have:

(8a + 2b - 4) + (3b - 5)

= 8a + 2b + 3b - 4 - 5 (grouping like terms)

= 8a + 5b - 9

Therefore, the sum of (8a + 2b - 4) and (3b - 5) is (8a + 5b - 9).

We can also explain this process by using the distributive property of addition over subtraction. This property states that the sum of two numbers with the same sign (positive or negative) can be found by adding their absolute values and keeping the common sign.

In this case, we can think of the expression (8a + 2b - 4) as the sum of three terms: 8a, 2b, and -4. Similarly, we can think of the expression (3b - 5) as the sum of two terms: 3b and -5.

Using the distributive property, we can add the terms with the same variable together:

(8a + 2b - 4) + (3b - 5)

= 8a + (2b + 3b) - (4 + 5)

= 8a + 5b - 9

200 m/s  is the wave speed of a wave that has a frequency .

What do you name a wave?

There are two different types of waves: longitudinal and transverse. Longitudinal waves are similar to those of sound in that they alternate between compressions and rarefactions in a medium, much like transverse waves in that the surface of the medium rises and falls.

                             The pattern of disruption brought about by the movement of energy through a medium (such as air, water, or any other liquid or solid matter) as it spreads away from the source of the sound is known as a sound wave.

The wave speed (v) of a wave can be calculated by multiplying its frequency (f) by its wavelength (λ). Mathematically, we can express this as

v = f x λ

Substituting the given values of frequency and wavelength into this formula, we get:

v = 500 Hz x 0.40 m

Multiplying these values, we get:

v = 200 m/s

Therefore, the wave speed of a wave that has a frequency of 500 Hz and a wavelength of 0.40 m is 200 m/s.
