Answer:

Angle of rotation of bike's tire is  = 6.29°

Step-by-step explanation:

Given: radius of  bike's tires 14 inches

           bike rolls forward 18 inches

To find:  the angle of rotation of the bike's tire

we know that,

Angle of rotation = \(\frac{distance covered by bike}{radius of bike's tire}\)

distance covered by bike is equal to the circumfernce of circle

we know that, circumference of circle = 2πr            

                                                                =2×\(\frac{22}{7}\)×14

                            circumference of circle =88.

Angle of rotation =\(\frac{88}{14}\)

                              = 6.29°

Answer:

Step-by-step explanation:

area of a circle = πr²

area = 3.14(3.5)²

area = 3.14 (12.25)

area = 38.465 ft²

The volume of the rectangular prism is 24 times larger than the volume of the cube.

Let's start by representing the dimensions of the cube as "x," so its volume would be \(x^3.\)

The dimensions of the rectangular prism can be represented as "2x," "3x," and "4x," so its volume would be \((2x)(3x)(4x) = 24x^3.\)

Now, we need to find out how many times larger the volume of the rectangular prism is compared to the cube.

To do this, we can divide the volume of the rectangular prism by the volume of the cube:

\((24x^3)/(x^3) = 24\)

So, the volume of the rectangular prism is 24 times larger than the volume of the cube.

Two non-planetary objects in the solar system are asteroids and comets.

What are the non-planetary abjects?

Asteroids are rocky objects that orbit the sun, primarily located in the asteroid belt between Mars and Jupiter. They can range in size from small pebbles to large objects over 500 km in diameter. Asteroids are believed to be remnants from the early solar system, and studying them can provide insights into the formation and evolution of the planets.

Comets are icy objects that originate from the Kuiper belt or the Oort cloud, which are located far beyond the orbit of Neptune. They have a distinct coma (a fuzzy atmosphere) and a tail that can extend for millions of kilometers as they approach the sun. Comets are believed to be remnants from the early solar system and contain information about the formation of the outer planets and the early solar system.

While both asteroids and comets are remnants from the early solar system, they differ in composition and behavior. Asteroids are primarily composed of rock and metal, while comets are made up of ice, dust, and rocky material. Comets also have highly elliptical orbits that can take them far from the sun, while asteroids have more circular orbits.

Answer:

About 50.14 Centimeters

Step-by-step explanation:

The formula for the volume of a cylinder is:

\(\pi(r^2)h\)

Now, let's plug in the values. (We'll use 3.14 for pi.)

\(3.14(r^2)76 = 600,000\)

All we do now, is solve for r. Divide 76 on both sides...

\(3.14(r^2) = 7894.74\)

Divide 3.14 on both sides...

\(r^2 = 2514.25\)

Lastly, find the square root on both sides.

\(\sqrt{r^2} = \sqrt{2514.25}\)

\(r = 50.14\)

Therefore, the r, or the radius, is around 50.14 centimeters. Hope this helps!

The position of the swing changes based on how hard it is pushed. To determine which pairs of segments are congruent, let's consider the swing as a pendulum.

A pendulum swings back and forth due to the force of gravity and its initial displacement. The distance from the pivot point to the center of mass of the swing is called the radius of oscillation.

When the swing is pushed harder, it gains more energy and swings with a larger radius of oscillation. Conversely, when the swing is pushed with less force, it swings with a smaller radius of oscillation.

Since the radius of oscillation affects the swing's position, the segments that would be congruent are the segments of the swing's path at two different moments in time when the swing has the same radius of oscillation.

For example, if the swing is pushed with a moderate force, the segments of the swing's path when it reaches the highest point on each side would be congruent. Similarly, the segments when the swing is at the lowest point on each side would also be congruent.

In summary, the segments that are congruent are the segments of the swing's path at different moments in time when the swing has the same radius of oscillation.

Step-by-step explanation:

The ordered pair (10,63) is a solution to the inequality y < -0.2x² + 9x - 7. This illustrates that the statement is true.

It should be noted that an inequality simply means a statement of an order relationship between two numbers and algebraic expressions.

From the information given, the equation illustrated is:

y < -0.2x² + 9x - 7.

63 < 0.2(10)² + (9 × 10) - 7

63 < 20 + 90 - 7.

True.

A 95% confidence interval for the population mean means that if we draw multiple samples from the same population and construct confidence intervals for the mean using each sample, then 95% of those intervals will contain the true population mean. This is because the confidence interval is computed based on the sample mean and the sample's standard deviation, which are random variables that are expected to vary from sample to sample. Therefore, we cannot be 100% certain that the true population mean is within any particular confidence interval, but we can be confident (95% confident, in this case) that most of the intervals we construct will contain the true mean. A 95% confidence interval for the population mean implies that if samples are drawn repeatedly and confidence intervals for μ are constructed, then 95% of the confidence intervals computed will contain the population mean. This means that you can be 95% confident that the true population mean lies within the calculated interval.

1/√2 = 4 / AC

AC = 4√2 cm

f is inversely proportional to √ g . When f = 8 , g = 25 Work out f when g = 16

By question , f is inversely proportional to square root of g. In mathematical form ,

\(\implies f \propto \dfrac{1}{\sqrt g}\)

Let k be constant . So that ,

\(\implies f =k \dfrac{1}{\sqrt g}\)

When f = 8 , g is 25. So that ,

\(\implies 8= k\dfrac{1}{\sqrt {85}}\)

\(\implies k = 8\sqrt{25} \)

Hence the value of constant is 8√25.

So that when g is 16 ,

\(\implies f = 8\sqrt{25} \times 1/ \sqrt{16}\\\\\implies f = 8*5 / 4 \\\\\implies \boxed{ f = 10 } \)

Hence the Value of f is 10 .
