Please Help!!! A bicycle has wheels 28 inches in diameter. tachometer determines that the wheels are rotating at 180 RPM (revolutions per minute). Find the speed the bicycle is traveling down the road.

Answers

Answer 1

Answer:

402.336 meters per minutes

Step-by-step explanation:

revolutions per minute = speed in meters per minute / circumference in meters.

Diameter = 28 inches

Circumference of the wheel = 2πr

r = Diameter/2 = 28/2 = 14

Circumference = 2 × π × 14

= 87.964594301 inches

Approximately = 88 inches

Note that:

1 inch = 0.0254 metre

88 inches = x

x = 88 × 0.0254 meters

x = 2.2352 meters

Hence:

Revolutions per minute = Speed in meters per minute / circumference in meters.

Speed = Revolutions per minute × circumference in meters.

Speed = 180 RPM × 2.2352 meters

Speed = 402.336 meters per minutes

Answer 2

Speed of the bicycle traveling down the road = 84π.

It is given that

Diameter of the wheel (2r) = 28 inches, where 'r' is the radius

Speed N(in revolutions per minute) = 180rpm

What is the formula for angular speed?

Angular speed ω = [tex]\frac{2\pi N}{60}[/tex]radian per second.

[tex]w= \frac{2*\pi*180 }{60 } = 6\pi[/tex] radian per second

Speed of bicycle V = r*ω

Where,

r= radius of the wheel

[tex]V = 14*6*\pi = 84\pi inches/second[/tex]

Therefore,

speed of the bicycle traveling down the road = 84π.

Deon is playing fetch with his dog with a toy that is shaped like a circle. The circumference of the toy is 12π inches.

Which measurement is closest to the area of the toy in square inches?


18.84 in.²

37.68 in.²

113.04 in.²

452.16 in.²

Answers

Answer:

113.04

Step-by-step explanation:

The required measurement is closest to the area of the toy is [tex]113.04\ inches^{2}[/tex]

Given that,

Deon is playing fetch with his dog with a toy that is shaped like a circle,

The circumference of the sculpture is 12π inches.

We have to determine,

Which measurement is closest to the area of the toy in square inches.

According to the question,

Circumference of the circle = [tex]2\pi r[/tex]

Where, circumference = [tex]12\pi[/tex]

Then,

[tex]12\pi =2\pi r \\\\r = \dfrac{12\pi }{2\pi }\\\\r = 6\ inches[/tex]

Therefore,

Deon is playing fetch with his dog with a toy that is shaped like a circle.

Area of the circle = [tex]\pi r^{2}[/tex]

Where, r = 6inches

Then,

Area of the circle is given by,

[tex]= \pi r ^{2}\\\\= 3.14 \times (6)^{2}\\\\= 3.14 \times 36\\\\= 113.04\ inches^{2}[/tex]

Hence, The required measurement is closest to the area of the toy is [tex]113.04\ inches^{2}[/tex].

Answers

Answer:

7

Step-by-step explanation: (dont trust me)

x^2 + (7)x +18

x(x + 4) + 3(x + 6)

Answer:

See the attachment for what goes on your X diagram.

Rewrite: x² -7x +4x -28

Grouping: (x² -7x) +(4x -28) = x(x -7) +4(x -7) = (x +4)(x -7)

Step-by-step explanation:

The given quadratic is ...

... x² -3x -28 . . . . . a=1, b=-3, c=-28

a) The value at the top of the X diagram is the product a·c = 1·(-28) = -28.

The value at the bottom of the X diagram is the coefficient b = -3.

The values on the sides of the diagram are the factors of -28 that add up to make -3. These are -7 and 4. That is, ...

(-7)·(4) = -28

(-7)+(4) = -3

b) Since the two values on the sides of the diagram add up to give "b", the value of "b" in the equation can be rewritten as the sum of these two numbers. Doing that, we have ...

... x² -3x -28

... = x² +(-7+4)x -28

... = x² -7x +4x -28 . . . . . . order does not matter. It could also be x² +4x -7x -28

c) We can group pairs of terms in the rewritten expression and factor each pair.

... = (x² -7x) +(4x -28) . . . . . first pair has a common factor of x; second pair, 4

... = x(x -7) +4(x -7) . . . . . . . these terms now have a common factor: (x -7)

... = (x +4)(x -7) . . . . . . . . . . the complete factorization of x² -3x -28

Comment on extended application

When a ≠ 1, there are a couple of additional steps. Effectively, you reduce the fractions ax/p and ax/q to a'x/p' and a''x/q'', then rewrite those as the factors (a'x+p')(a''x+q'') where the ' and '' numbers are after reducing the fractions. (The numbers may be the same as the original if the fraction cannot be reduced.) As a check, a'·a'' = a, and p'·q'' = c.

what is the product of 2 4/7 × 13/12​

Answers

Answer:

2 11/14

Step-by-step explanation:

First make both of them improper fractions.

therefore,

2 4/7 = 18/7

now simplify.

18/7 × 13/12

18 and 12 get cancelled off as they're multiples of 3 and 6

therefore,

3/7 × 13/2

3× 13 = 39

7×2 = 14

39/14

now make it a proper fraction

A person Rents a canoe for 4 Hours and paid a total of $36. of Renting a canoe costs am initial fee of the $2 Plus an additional amount for each hour the canoe is rented,which graph represents the total cost,y, in dollars of renting a canoe for x hours

Answers

Answer:

Additional fee or hour = $8.5

y = $2 + 8.5x

Step-by-step explanation:

Given that :

Total paid = $36

Number of hours = 4

Initial rental fee = $2

Additional fee per hour = a

Total amount = initial rental fee + additional fee per hour * number of hours

36 = 2 + 4a

36 - 2 = 4a

34 = 4a

a = 8.5

Hourly fee = $8.5

Therefore, the cost formula

y = initial fee + regular fee * number of hours

y = $2 + 8.5x
