Answer:

Claire is standing at a distance of 485.45 meters to Chloe.

Step-by-step explanation:

The track is a circular with a radius of 100 meters.

The total length of the circular track = length of the circumference of a circle

But, length of the circumference of a circle = 2[tex]\pi[/tex]r

So that,

total length of the circular track = 2[tex]\pi[/tex]r

                                            = 2 × [tex]\frac{22}{7}[/tex] × 100

                                           = 628.57

The total length of the circular track is 628.57 meters.

Thus,

the distance of Claire to Chloe = total length of the circular track - distance of Chloe to Claire

                                                             =  628.57 - 143.12

                                                             = 485.45

This means that Claire is standing at a distance of 485.45 meters to Chloe.

Answer:

The number of fries and shakes sold are 70 and 35 respectively.

Step-by-step explanation:

The number of fries sold can be denoted by x.

The number of shakes sold can be denoted by y.

The equation representing the total number of items sold is:

x + y = 105...(i)

The cost fries is, $2.

The cost of shakes is, $3.

The equation representing the total money earned is:

2x + 3y = 245...(ii)

Solve equations (i) and (ii) simultaneously as follows:

Multiply equation (i) by 3 and subtract:

3x + 3y = 315

2x + 3y = 245

(-)     (-)      (-)

___________

x = 70

Compute the value of y as follows:

x + y = 105

70 + y = 105

y = 105 - 70

y = 35

Thus, the number of fries and shakes sold are 70 and 35 respectively.

Answer:

[tex]\dfrac{24}{31}[/tex]

Step-by-step explanation:

Given information:

Total number of girls = 14

Total number of boys = 17

Total number of peoples = 14 + 17 = 31

6 girls and 7 boys brought balloons.

Let A and B are two events, such that

A = Choosing a girl

B = Choosing someone who did not bring a balloon.

[tex]A\cup B[/tex] = Choosing girl or someone who did not bring a balloon.

[tex]n(S)=31,n(A)=14,n(B)=18,n(A\cup B)=14+10=24[/tex]

The probability of randomly choosing a girl or someone who did not bring a balloon is

[tex]P=\dfrac{n(A\cup B)}{n(S)}[/tex]

[tex]P=\dfrac{24}{31}[/tex]

Therefore, the required probability is [tex]\dfrac{24}{31}[/tex].

The probability of randomly choosing a girl or someone who did not bring a balloon at a party is 24 out of 31, which simplifies to the fraction 24/31.

To solve this problem, we can use the concept of probability and the addition rule since the events are not mutually exclusive.

First, let's define the total number of people at the party: 14 girls + 17 boys = 31 people.

Next, we look at the number of girls who brought balloons, which is 6, meaning there are 14 - 6 = 8 girls who did not bring balloons.

Similarly, 17 boys - 7 boys who brought balloons = 10 boys who did not bring balloons.

Now, let's calculate the number of ways to choose a girl or someone who did not bring a balloon. For the girls, it's simply the total number of girls, 14. For those who did not bring balloons, we need to add the number of girls who did not bring balloons to the number of boys who did not bring balloons: 8 girls + 10 boys = 18 people who did not bring a balloon.

Combining these, the event of choosing a girl overlaps with the event of choosing someone who did not bring a balloon, so we have to subtract the number of girls who did not bring a balloon once to avoid double-counting: 14 + 18 - 8 = 24.

Thus, the probability is: 24 out of 31, which we can write as 24/31.

Final answer:

The volume of the cube-shaped box, with each side measuring 1 foot, is 1 cubic foot, calculated by multiplying the length by the width by the height.

Explanation:

To find the volume of a cube-shaped box, you multiply the length by the width by the height. Since the box in question has a length, width, and height of 1 foot each, the calculation is quite straightforward:

Volume = length × width × height

Volume = 1 ft × 1 ft × 1 ft

Volume = 1 cubic foot

Therefore, the volume of the cube-shaped box is 1 cubic foot.

Accoridng to your question we have to find the square root of 0.0025

However students face some problem in finding square roots of number in decimal but it is too easy to find .

√0.0025

0.05 is the square root of 0.0025

after decimal there are two zero and by square root there will be one zero and 25 is the square root of 5 .

so thus we find the square root amd the correct answer is 0.05

The square root of 0.0025 is 0.05, which follows the rule that the square root of a decimal results in half the number of decimal places in the square root, compared to the original number.

The student has asked to find the square root of 0.0025. When expressed as a square root, the number 0.0025 is equal to 0.05 because (0.05 * 0.05 = 0.0025). This can be understood by recognizing that the decimal places need to be managed correctly when finding the square root of a decimal. For instance, the square root of 25 is 5, and since 0.0025 has four decimal places, the square root will have half as many decimal places, resulting in 0.05. This concept is further emphasized by using fractional powers, such as re-expressing a number squared (x²) as the square root ( √x ), where x to the power of 2 is the same as x to the power of 1/2.

Answer:

848 ft³

Step-by-step explanation:

The volume of a cylinder is given as:

V = pi * r² * h

Where r = radius of the cylinder

h = length of the cylinder.

The diameter of the cylindrical pipe, d = 6 ft

The radius of the cylindrical pipe, r = d/2 = 6 / 2 = 3 ft

The length of the cylindrical pipe, h = 30 ft

The volume of the cylindrical pipe is:

V = 3.14 * 3² * 30

V = 847.8 ft³ = 848 ft³ (to the nearest whole number)

The volume of the cylindrical pipe is 848 ft³.

The volume of a cylindrical construction pipe with a diameter of 6 ft and length of 30 ft can be calculated using the formula for the volume of a cylinder (V = πr²h). Given the specifics, the volume of the pipe is approximately 848 cubic feet.

The subject of this question is determining the volume of a cylinder, in this case, a construction pipe. The formula used to calculate the volume of a cylinder is V = πr²h. Here, the diameter of the cylindrical pipe is 6 ft, therefore radius (r) is half of diameter which is 6/2 = 3 ft and the length of the pipe, h, is 30 ft. Substituting r and h into the equation, we have V = 3.14 * (3ft)² * 30ft = 3.14 * 9ft² * 30ft = 847.8 cubic feet. Rounding to the nearest whole number, the volume of the pipe is approximately 848 cubic feet. The unit of volume in this instance is cubic feet, which is a measure of space occupied by a three-dimensional object.

Hi, to calculate the amount of cardboard needed to create a cereal box we have to calculate the total surface area.

The volume is used to calculate the amount of cereal that the box can contain, and the lateral surface area will not include all the cardboard needed for the complete box.

Feel free to ask for more if needed or if you did not understand something.

To calculate the amount of cardboard needed to create a cereal box, we would be solving for the Total Surface Area. This is the sum of the areas of all the faces (or sides) of the box.

When we talk about the amount of cardboard needed to create a cereal box, we are interested in determining the

Total Surface Area

of the box. The surface area is the measure of the total amount of material needed to cover the surface of an object. If we're considering a cereal box, which is a three-dimensional rectangular prism, its total surface area is calculated by summing up the areas of all its six faces (top and bottom, front and back, left and right). Specifically, the formula for the total surface area of a box or rectangular prism is 2lw + 2lh + 2wh where l is the length, w is the width, and h is the height.

Answer:

It will take 26 years

Step-by-step explanation:

In this question, we are tasked with calculating the time it will take for an amount of money earned to be tripled if compounded continuously.

To calculate this amount of time, we are going to use the formula for compound interest.  Mathematically, for an interest compounded, the amount is as follows;

[tex]A = P(1 + r/n)^{nt}[/tex]

Where;

A is the amount at the end of compounding; which is 3 times the original amount = 3 × $200 = $600

P is the initial amount = $200

r is the rate of compounding = 4.25% = 4.25/100 = 0.0425

n is the number of times in which the amount is compounded annually, we take this as 1

t is the time taken to reach the amount

We substitute these values in the equation;

600 = 200(1 + 0.0425/1)^t

Divide through by 200

3 = (1.0425)^t

Take the logarithm of both sides

log 3 = log(1.0425)^t

log 3 = tlog 1.0425

t = log 3/log1.0425

t = 26.4 which is approximately 26 years

Answer:

Increasing: [tex]x<-1[/tex] and [tex]x>1[/tex].

Decreasing: [tex]-1<x<1[/tex]

Step-by-step explanation:

We have been given a function [tex]f(x)=x^3-3x+4[/tex]. We are asked to determine the intervals, where the function is increasing and where it is decreasing.

First of all, we will find critical points of our given function by equating derivative of our given function to 0.

Let us find derivative of our given function.

[tex]f'(x)=\frac{d}{dx}(x^3)-\frac{d}{dx}(3x)+\frac{d}{dx}(4)[/tex]

[tex]f'(x)=3x^{3-1}-3+0[/tex]

[tex]f'(x)=3x^{2}-3[/tex]

Let us equate derivative with 0 as find critical points as:

[tex]0=3x^{2}-3[/tex]

[tex]3x^{2}=3[/tex]

Divide both sides by 3:

[tex]x^{2}=1[/tex]

Now we will take square-root of both sides as:

[tex]\sqrt{x^{2}}=\pm\sqrt{1}[/tex]

[tex]x=\pm 1[/tex]

[tex]x=-1,1[/tex]

We know that these critical points will divide number line into three intervals. One from negative infinity to -1, 2nd -1 to 1 and 3rd 1 to positive infinity.

Now we will check one number from each interval. If derivative of the point is greater than 0, then function is increasing, if derivative of the point is less than 0, then function is decreasing.

We will check -2 from our 1st interval.

[tex]f'(-2)=3(-2)^{2}-3=3(4)-3=12-3=9[/tex]

Since 9 is greater than 0, therefore, function is increasing on interval [tex](-\infty, -1) \text{ or } x<-1[/tex].

Now we will check 0 for 2nd interval.

[tex]f'(0)=3(0)^{2}-3=0-3=-3[/tex]

Since -3 is less than 0, therefore, function is decreasing on interval [tex](-1,1) \text{ or } -1<x<1[/tex].

We will check 2 from our 3rd interval.

[tex]f'(2)=3(2)^{2}-3=3(4)-3=12-3=9[/tex]

Since 9 is greater than 0, therefore, function is increasing on interval [tex](1,\infty) \text{ or } x>1[/tex].

Answer:

x = -11

Step-by-step explanation:

3x - 4 + 2(x - 5) = 9x + 8 - 2x

3x - 4 + 2x - 10 = 9x + 8 - 2x

3x + 2x - 9x + 2x = 8 + 10 + 4

- 2x = 22

- x = 22/2

- x = 11

x = - 11

The equation 3x - 4+2(x-5)= 9x + 8- 2x can be solved by first simplifying to 5x - 4 = 7x + 8. After re-arranging, it simplifies to -12 = 2x, and therefore, x = -6.

To solve this equation, first simplify and combine like terms on each side of the equation. That gives us: 5x - 4 = 7x + 8. Next, let’s get all the x terms on one side. To do that, we subtract 5x from both sides, which gives us -4 = 2x + 8. Then, subtract 8 from both sides to isolate the 'x', resulting in -12 = 2x. Finally, divide both sides by 2 to find the value of x, which is -6.

Answer:

4 m/s downwards

Step-by-step explanation:

Velocity is given by dividing the distance by time taken to cover the diatance. Therefore, expressed as v=d/t

The distance is given as 24 m but the time given covers only half the distance. Therefore, the distance is 0.5*21=12 m

Time taken is given as 3 s

Substituting 12 m for d and 3 s for t then

V=12/3= 4 m/s

Velocity must have direction component hence velocity is 4 m/s downwards
