Answer: The wheels turn about 3771 times in 5 miles.

Step-by-step explanation:

Given, Kelly rides on her bicycle such that the number of times wheels turn for every 140 feet = 20

Turns for every feet = [tex]\dfrac{20}{140}=\dfrac{1}{7}[/tex] ...(i)

To find : Number of times wheels turn in 5 miles.

Since , 1 mile = 5,280 feet

Then, 5 miles = 5 x (5,280 feet) = 26,400 feet

Now , Number of times the wheels turn in 26,400 feet = 26400 x (Turns for every feet)

[tex]26400\times\dfrac{1}{7}=3771.42857143\approx3771[/tex]   [From (i)

Hence, the wheels turn about 3771 times in 5 miles.

Explanation:

The measure of the two sides of the triangle are 5√3 & 5 units respectively.

In mathematics, trigonometric functions are real functions that relate an angle of a right-angled triangle to ratios of two side lengths. The six trigonometric functions are Sine, Cosine, Tangent, Secant, Cosecant, and Cotangent.

Given here: A triangle ABC with angle as C as a right angle and the hypotenuse is equal to 10

Let the perpendicular and the base of the triangle is p and b respectively.

Thus

Sin 60=p/10

p=10×√3/2

p=5√3

Also, Cos 60=b/10

             b=10×1/2

             b=5

Hence, The measure of the two sides of the triangle are 5√3 & 5 units respectively.

Answer:

The area of the octagon is 505.76 [tex]inches^{2}[/tex]

Step-by-step explanation:

In this question, we are tasked with calculating the area of an octagon given the values of the apothem and the perimeter

Mathematically, the area can be calculated using the formula below;

Area = 1/2 × apothem × perimeter

where according to the question, the apothem = 11.6 inches and the perimeter = 87.2 inches

Plugging these value into the equation given above, we have

Area = 1/2 × 11.6 × 87.2 = 505.76 [tex]inches^{2}[/tex]

Step-by-step explanation:

Answer:

Step-by-step explanation:

If two quantities are inversely proportional, it means that an increase in the value of one variable would cause a corresponding decrease in the other variable and vice versa.

Given that M varies inversely as the square of P, if we introduce a constant of proportionality, k, the expression becomes

M = k/P²

If M = 9 when P = 2, then

9 = k/2² = k/4

k = 9 × 4 = 36

Therefore, the inverse variation equation is

M = 36/P²

When P = 3,

M = 36/3² = 36/9

M = 4

Step-by-step explanation:

to convert the centimeters to inches, divide 137. 16 by 2.54

you should get 54

then divide by 18

you get three

You can make 3 necklaces from 137.16 centimeters of silver chain, given that each necklace is 18 inches long. We first converted the necklace length to centimeters, and then divided the total length of silver chain by the length of each necklace.

To find out how many necklaces can be made from 137.16 centimeters of silver chain, we first need to convert the units because the length of the necklace chain is given in inches, while the total amount of silver chain is given in centimeters.

We know that 1 inch is equal to 2.54 centimeters. Therefore, if each necklace is 18 inches long, the length of each necklace in centimeters is 18 inches * 2.54 cm/inch = 45.72 cm.

Now, to find the number of necklaces that can be made, we divide the total length of silver chain by the length of each necklace. That is 137.16 cm / 45.72 cm/necklace = 3 necklaces (rounded down to the nearest whole necklace, because we cannot make a fraction of a necklace).

The slope is determined by change in y / change in x.

Here we can see that it takes 3 blocks from (1,1) until the line is on an integer, (4,2) and that y increases by one while x increases by 3.

Given:

It is given that the value of the graph when the input 7 is [tex]g(x)=4[/tex]

We need to determine the value of x when [tex]g(x)=4[/tex]

Value of x when [tex]g(x)=4[/tex]:

The value of x can be determined by using the graph.

From the graph, we need to determine the value of x when [tex]g(x)=4[/tex] other than the value x = 7.

This can be determined by finding the point at which the line meets the point y = 4, we can find the corresponding x - value.

Thus, from the graph, it is obvious that the graph also meets the point y = 4 when x = -8.

Therefore, the input value is x = -8 which makes [tex]g(x)=4[/tex]

Hence, the input value other than 7 for which [tex]g(x)=4[/tex] is x = -8.

The input value other than 7 for which g(x) = 4 is x = -8.

It is given that the value of the graph when the input 7 is g(x)=4

We need to determine the value of x when g(x)=4

Value of x when g(x)=4:

The value of x can be determined by using the graph.

This can be determined by finding the point at which the line meets the point y = 4, we can find the corresponding x - value.

From the graph, we get that the graph of g(x) passes through the point (x = -8, y = 4),

Thus, from the graph, it is obvious that the graph also meets the point y = 4 when x = -8.

Then indeed, the input value (x) other than 7 for which g(x) = 4 is x = -8.

As, the function g(x) takes the value of 4 at x = -8, according to the graph.

Therefore, the input value is x = -8 which makes g(x) = 4.

Hence, the input value other than 7 for which g(x) = 4 is x = -8.

We have been given that Darren invests $4,500 into an account that earns 5% annual interests. We are asked to find the amount in his account after 10 years, if the interest rate is compounded annually, quarterly, monthly, or daily.

We will use compound interest formula to solve our given problem.    

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

A = Final amount,

P = Principal amount,

r = Annual interest rate in decimal form,

n = Number of times interest is compounded per year,

t = Time in years.

[tex]5\%=\frac{5}{100}=0.05[/tex]

When compounded annually, [tex]n=1[/tex]:

[tex]A=4500(1+\frac{0.05}{1})^{1\cdot 10}[/tex]

[tex]A=4500(1.05)^{10}[/tex]

[tex]A=4500(1.6288946267774414)[/tex]

[tex]A=7330.025820498\approx 7330.03[/tex]

When compounded quarterly, [tex]n=4[/tex]:

[tex]A=4500(1+\frac{0.05}{4})^{4\cdot 10}[/tex]

[tex]A=4500(1.0125)^{40}[/tex]

[tex]A=7396.28758569\approx 7396.29[/tex]

When compounded monthly, [tex]n=12[/tex]:

[tex]A=4500(1+\frac{0.05}{12})^{12\cdot 10}[/tex]

[tex]A=4500(1.00416666)^{120}[/tex]

[tex]A=4500(1.64700949769)[/tex]

[tex]A=7411.542739605\approx 7411.54[/tex]

When compounded daily, [tex]n=365[/tex]:

[tex]A=4500(1+\frac{0.05}{365})^{365\cdot 10}[/tex]

[tex]A=4500(1.0001369863013699)^{3650}[/tex]  

[tex]A=4500(1.6486648137656943695)[/tex]

[tex]A=7418.9916619456\approx 7419.00[/tex]

Since amount earned will be maximum, when interest is compounded daily, therefore, Darren should use compounded daily interest rate.

Step-by-step explanation:

Data

Rectangular pyramid

base = 100 yd x 78 yd

height = 100 yd

weight of a stone = 468 lb/yd³

Process

1.- Calculate the volume of the pyramid

Volume = area of the base x height

-Substitution

Volume = 100 x 78 x 100

-Simplification

Volume = 780000 yd³

2.- Calculate the weight of the pyramid

                     468 lb ------------------------ 1 yd³

                         x      ------------------------780000 yd³

                         x = (780000 x 468) / 1

Answer:

sin ( θ ) = 3√21 / 17

Step-by-step explanation:

Given:-

- The angle (θ) lies in the first quadrant. Where theta is defined as:

                               cos ( θ ) = 10 / 17

Find:-

- Find sin ( θ ) :

Solution:-

- We will draw a right angle triangle in the first quadrant. With base, B = 10 and hypotenuse H = 17. Since,

                               cos ( θ ) = B / H = 10 / 17

- Using pythagorean theorem determine the perpendicular side length:

                               H^2 - B^2 = P^2

                               17^2 - 10^2 = P^2

                               √189 = P

                              P = 3√21

- Now evaluate sin ( θ ):

                               sin ( θ ) = P / H

                               sin ( θ ) = 3√21 / 17
