The speed of light is about 2.998 x 10^8 meters per second. The speed of sound is about 343 meters per second. About how many times faster
is light than sound?

Answers

Answer 1

Light is about 874052.5 times faster than sound

Calculating speed

From the question, we are to determine the magnitude by which light is faster than sound

From the given information,

The speed of light is about 2.998 x 10⁸ meters per second.

and

The speed of sound is about 343 meters per second.

To determine how many rimes faster the speed of light is than the speed of sound, we will divide the speed of light by the speed of sound

That,

The magnitude by which light is faster than sound = (2.998 x 10⁸) / 343

The magnitude by which light is faster than sound = 874052.5

Hence, light is about 874052.5 times faster than sound

Answer:

∠ N = 10° , arc RS = 134°

Step-by-step explanation:

the measure of an inscribed angle is half the measure of its intercepted arc.

(5)

∠ N is an inscribed angle and we require arc LM

the measure of the arcs in a circle = 360°

note LN is the diameter so arc LN = 180°

Then

LM + MN + LN = 360°

LM + 160° + 180° = 360°

LM + 340° = 360° ( subtract 340° from both sides )

LM = 20°

then

∠ N = [tex]\frac{1}{2}[/tex] LM = [tex]\frac{1}{2}[/tex] × 20° = 10°

(6)

∠ Q is an inscribed angle so its intercepted arc is twice its measure

arc RS = 2 × 67° = 134°

Total carbohydrates he ate = 220 grams

Carbohydrates intake from whole grains = 55 grams

Percentage of carbohydrates in whole grains = (Carbohydrates from whole grain/Total carbohydrate intake)*100

=(55/220)*100

=0.25*100

If the length of the shorter arc AB is 22cm and C is the center of the circle then the circumference of the circle

Answers

The circumference of the circle with arc AB as 22 cm and C as the center will be 176 cm.

We are given that:

Length of the shorter arc forming an angle of 45° with the center = 22 cm

AB = 22 cm

C is the center of the circle.

We know that the length of the arc is calculated as:

Length of an Arc = θ × (π / 180) × r

22 = 45 × (3.14 / 180) × r

22 = 0.785 r

r = 22 / 0.785

r = 28.0255

Circumference = 2 π r

Circumference = 2(3.14) (28.0255)

C = 176 cm

Therefore, we get that, the circumference of the circle with arc AB as 22 cm and C as the center will be 176 cm.

Answers

The difference quotient of the function g(x) = √x is  [√(x+h) -√x]/h

Difference quotient of the function:

Difference quotient of the function means a measure of the average rate of change of the function over an interval.

The difference quotient formula of a function y = f(x) is,

[ f(x + h) - f(x) ] / h

where

f (x + h) is obtained by replacing x by x + h in f(x)

f(x) is the actual function

Given,

Function g(x) = √x where x≥0.

Here we need to find the difference of the quotient of the function.

For that,

First we have to calculate the value of g(x + h),

By simply replacing the value of x as x + h,

So,

g(x + h) = √(x+h)

Now apply the values on the formula in order to solve it,

=> [√(x+h) -√x]/h

find x

Answers

After simplifying the equation we acquire the value of x as:

x = 1.225 or x = ₋12.225

Given the equation is x² ₊ 11x ₊ 15 = 30

arrange the constants on one side.

x² ₊ 11x = 30 ₋ 15

x² ₊ 11x = 15

x² ₊ 11x ₋ 15 = 0

now simplify the equation using the formula: -b±√b²₋4ac / 2a

in the equation we have the values for a = 1 , b = 11 and c = ₋15

substitute the values and get the value of x.

= ₋11 ± √(11)² ₋ 4(1)(₋15) / 2(1)

= ₋11 ± √121 ₊ 60 / 2

= ₋11 ± √181 / 2

= ₋11 ± 13.45 / 2

= ₋11 ₊ 13.45 / 2 or ₋11 ₋ 13.45 / 2

= 2.45/2 or ₋24.45/2

= 1.225 or ₋12.225

Therefore x value is 1.225 or ₋12.225

If two cellphones are randomly selected from the box what is the probability there will be one green cellphnone and one yellow cellphone?

Answers

The probability that one green and one yellow is selected (without replacement) is 3/7.

What are examples and probability?

It is predicated on the likelihood that something will occur. The justification for probability serves as the basic foundation for theoretical probability. For instance, the theoretical chance of receiving a head while tossing a coin is 12.

Probability that one green and one yellow is selected (without replacement).

Since the cellphone is not replaced, the probability is calculated as follows

Pr = [tex]\frac{G}{n} * \frac{Y}{n - 1 } + \frac{Y}{n} * \frac{G}{n- 1}[/tex]  The subtraction means the cellphones are not replaced

This gives

[tex]Pr = \frac{6}{8} * \frac{2}{8 - 1} + \frac{2}{8} * \frac{6}{8 - 1}[/tex]

[tex]Pr = \frac{3}{4} * \frac{2}{7} + \frac{1}{4} * \frac{6}{7}[/tex]

[tex]Pr = \frac{3}{14} + \frac{3}{14}[/tex]

take lcm

[tex]Pr = \frac{3}{7}[/tex]

Answers

In 25.76 seconds we will fill the total volume of the cylinder.

how long will it take the faucet to fill the vase?

The total volume of the cylinder is given by the equation:

V = pi*R^2*H

Where pi = 3.14, R is the radius and H is the height.

Here we know that the diameter is 6 inches, then the radius is:

R= 6in/2 = 3in

And the height is 8 inches, then the volume is:

V = 3.14*(3in)^2*8in = 226.08 in^3

We already have 20 cubic inches of water there, so what we need to fill is:

226.08 in^3 - 20in^3 = 206.08in^3

If we fill it at a rate of 8in^3/s, the time in which we will completely fill the cylinder is:

T = 206.08in^3/8in^3/s = 25.76s

In 25.76 seconds we will fill the total volume of the cylinder.

a bottle weighs 300gand holds 630ml,how much does it weight if i fill it with water

Answers

If a bottle weighs 300g and can hold 630ml, then it will weigh approximately 930g when filled with water.

As per the question statement, a bottle weighs 300g and can hold 630ml.

We are required to find out the weight of the bottle when it is filled up with water.

To solve this question, we need to know about the concept of density of a substance, i.e.,

[tex]Density=\frac{Mass}{Volume}\\ or, Mass=[Density*Volume][/tex].

And density of water is 1gm/ml, i.e., 1gm of water has a mass of 1ml.

Using the above info, we will calculate the mass of 630ml of water and then we will have to add up the mass of water and the mas of the bottle to obtain our desired answer.

Using the unitary method, if 1ml of water has a mass of 1gm, then,

630 ml of water has a mass of [tex](630*1)=630\\[/tex] gms.

Hence, total weight of the bottle filled with water will be

[tex](630+300)=930[/tex] gms.

Density: Density is the measure of degree of compactness of a substance, calculated as the ratio of Mass to volume of a substance.Unitary Method: This is a technique for solving a problem where first, we find the value of a single unit, and then find the necessary value by multiplying the single-unit value.

If the samples are large and the standard deviations are small, the differences between the two samples are least likely to be statistically significant.

How does standard deviation work?

The term "standard deviation" (or "") refers to the degree of dispersion of the data from the mean. Data are grouped around the mean when the standard deviation is low, and are more dispersed when the standard deviation is high.

Why is statistical significance important?

"Statistical significance precision" tells us, in Redman's words, "whether a result is probably caused by chance via some factor of interest."
