Divide 2/3 by 8/15. Simplify your answer

The slope of the line in the image is a zero slope.

The slope of a line can be defined as the ratio of a line's vertical change to the line's horizontal change, which is rise/run or change in y / change in x.

An horizontal line has horizontal change but no vertical change. Therefore, no matter the horizontal change of the line, the slope of a horizontal line would always be zero. Therefore, horizontal lines have zero slope.

The line in the image is a horizontal line, therefore, the slope is neither positive nor negative, but a zero slope.

They could have biked on first day at the speed of x/4 miles per hour and on the second day at the speed of (88-x)/6 miles per hour where x is the distance covered on first day.

According to the question,

We have the following information:

Jaden and Emilia biked 88 miles from Daytona Beach to Jacksonville in 2 days. They spent 4 hours biking the first day and 6 hours biking the second day. They biked at one speed the first day and a different speed the next day.

Now, let's take the distance covered on first day to be x miles.

Distance covered on second day = 88-x miles

Following formula is used to find the speed of an object:

Speed = distance/time

Speed of first day = x/4 miles per hour

Speed of the second day = (88-x)/6 miles per hour

Hence, they could have biked on first day at the speed of x/4 miles per hour and on the second day at the speed of (88-x)/6 miles per hour where x is the distance covered on first day.

Using the properties of half-life we calculate that approximately 22.33 grams of radium will be present after 720 years.

The half-life of radioactive element radium = 1690 years.

Time = 720 years

the formula for calculating half life is given by:

[tex]N(t)&=N_{0}\left({\frac {1}{2}}\right)^{\frac {t}{t_{1/2}}[/tex]

Now we substitute the values to find the N(t) which is the amount of radium left after 720 years.

t = 720

half life = 1690

N₀ (initial mass) = 30gm

[tex]N(t)&=30\left({\frac {1}{2}}\right)^{\frac {720}{1690}[/tex]

N(t) = 22.329 gm

N(t) ≈ 22.33 gm

The half-life of a substance is the amount of time required for it to reach that point. The phrase is widely used in nuclear physics to describe how quickly unstable atoms decay radioactively or how long stable atoms remain.

Additionally, a broader definition of the term is used to characterize any exponential decay (or, very infrequently, nonexponential decay). For instance, a term used in the medical sciences is the biological half-life of drugs and other compounds in the human body.

The quadratic equation with a vertex at (-1, -5) that passes through (2, 13) is:

y = 2*(x + 1)^2 - 5

A quadratic equation with a leading coefficient a and a vertex (h, k) is written as:

y = a*(x - h)^2 + k

Here we know that the vertex is (-1, -5), then our parabola is something like:

y = a*(x + 1)^2 - 5

Now we also know that the quadratic equation contains the point (2, 13), then we can replace the values to get:

13 = a*(2 + 1)^2 - 5

13 = a*3^2 - 5

13 = a*9 - 5

13 + 5 = a*9

18/9 = a

Hey there! I would be glad to help you out.

For the first two miles, the price would be six dollars total.

For every mile after that, you would be charged two dollars.

Assuming that you travel 8 miles, you would have to pay six dollars for the first two miles (3*2), and twelve dollars for the last six miles, totaling eighteen dollars.

So the price of an eight mile ride would be eighteen dollars.

You can use this logic for the 50 miles trip too. After traveling 2 miles ($6), there will be 48 more miles.

For these 48 miles, it'll only charge you two dollars each, which would total 96 dollars.

So the price of a fifty mile ride would total $102.

The decision rule for rejecting the null hypothesis, considering the t-distribution, is of:

At the null hypothesis, it is tested if there is not enough evidence to conclude that the mean voltage for these two types of batteries is different, that is, the subtraction of the sample means is of zero, hence:

[tex]H_0: \mu_1 - \mu_2 = 0[/tex]

At the alternative hypothesis, it is tested if there is enough evidence to conclude that the mean voltage for these two types of batteries is different, that is, the subtraction of the sample means different of zero, hence:

Claire is 18 years old and her mother is 40 years old.

Answer with explanation:

Let Claire's age = x years

Age of Claire's mother =(2 x +4 ) years

Sum of the ages of Claire and her mother =58 years

If we write the above statement in terms of equation , it will be

⇒ x + 2 x +4=58

⇒3 x +4=58

⇒3 x =58 -4

⇒3 x =54

Dividing both side by , 3 , we get

→x=18

Claire's age = 18 years

Age of Claire's mother =(2 x +4 )=2×18+4=36+4= 40 years

The sum of their ages is 58. The "sum of their ages" includes:

Claire's age + 2(Claire's Gage) + 4 = 58

3(Claire's age) + 4 = 58

3 x Claire's age = 58 -4 = 54

Claire's age= 54/3 = 18

Claire is 18 years old.

Since Claire's mom is 4 years older than twice clears age, her age is (18 x 2) + 4 = 40

So Claire is 18 and her mother is 40

By using slope intercept form of equation of line, it can be inferred that Point C is on the line y = x - 5

What is equation of line in slope intercept form?

The most general form of equation of line in slope intercept form is given by y = mx + c

Where m is the slope of the line and c is the y intercept of the line.

Slope of a line is the tangent of the angle that the line makes with the positive direction of x axis.

If [tex]\theta[/tex] is the angle that the line makes with the positive direction of x axis, then slope (m) is given by

m = [tex]tan\theta[/tex]

The distance from the origin to the point where the line cuts the x axis is the x intercept of the line.

The distance from the origin to the point where the line cuts the y axis is the y intercept of the line.

Here, the given slope intercept form is y = x - 5

For Point A

Putting x = -3

y = -3 -5 = -8 which is not equal to 2

Point A is not on the line y = x - 5

For Point B

Putting x = 1

y = 1 -5 = -4 which is not equal to 6

Point B is not on the line y = x - 5

For Point C

Putting x = 3

y = 3 -5 = -2

Point C is on the line y = x - 5

For Point D

Putting x = -2

y = -2 -5 = -7 which is not equal to -3

Point D is not on the line y = x - 5

The value of x in the polygon is 9

A heptagon is a polygon that has seven sides. It is a closed figure having 7 vertices. A heptagon is also sometimes called Septagon.

In Geometry, the shape that is bounded by at least three straight lines or at least three interior angles is called polygon. The most common examples of polygons are

Triangle ( 3 sided polygon)

Quadrilateral ( 4 sided polygon)

Pentagon ( 5 sided polygon)

The polygon is a heptagon with number of sides n = 7

sum of interior angles of a polygon = (n - 2) x 180

if n = 7,

Sum of the interior angles = (7 -2) x 180

                                            = 5 x 180

                                            = 900

summing all the angles in the given polygon, we have

135 + 3x + 31 + 4x + 15 + 6x - 8 = 120 + 7x - 64 + 5x - 4 = 25x + 675

25x + 675 = 900

25x = 900 - 675

25x = 225

x = 225/25

x = 9

In conclusion, the value of x for the given polygon is 9

From the given data of traffic circle, the center of the circular monument is covering approximately 148,000 square feet then the radius of the monument is equal to 217.10 feet.

As given in the question,

Given that traffic circle is a round intersection.

It has circular monument in the center.

Area covered by circular monument is equal to 148,000 square feet.

Let us consider radius of the circular monument be 'r'

Area of circular monument  = 148,000

⇒ πr² = 148,000

⇒r² = 148,000 / π

⇒ r² = 148,000/ 3.14

⇒ r = √148,000/ 3.14

⇒ r = 217. 103... feet

⇒ r = 217.10 feet ( nearest hundredth)

32 is the next term in the arithmetic sequence of 24,16,8,0,...

To find out what is the next term of the arithmetic sequence

24, 16, 8, 0, ...

To show the explicit equation:

We have an arithmetic sequence because the difference between the terms is constant:

0 → 8: Δ → 8

8 → 16: Δ → 8

16 → 24: Δ → 8

From this the next term is simply:

24 + 8 = 32

And this sequence can be explicitly written as:

[tex]a_{n} = a_{1}(n-1)d[/tex]

Where:

[tex]a_{n}[/tex] = nth term

[tex]a_{1}[/tex] = first term

d = distance between the terms

n = any index number

Therefore we have:

[tex]a_{n} = 1.(n-1)8 = 8.(n-1)\\\\a_{n} = 8. (n-1)[/tex]
