A wheel of a child's bicycle has a circumference that is 50% of the circumference of a child's mountain bicycle wheel. The child's bicycle wheel has a circumference of 37.7 inches. a. What is the radius (to the nearest inch) of the child's bicycle wheel? of the child's mountain bicycle wheel? b. The child's mountain bicycle wheel takes 2 seconds to make 3 revolutions . How fast(to the nearest inch per second) is the bicycle moving?

Answers

Answer 1

Answer:

36960in per minute

Step-by-step explanation:

Answer 2

Answer:

a) 6 inchesb) 113 inches per second

Step-by-step explanation:

Let the child bicycle wheel radius be x

Then its circumference is

C = 2πx

a) Solving for x

37.7 = 2*3.14xx = 37.7/6.28x = 6.0 in

b) Mountain bicycle has twice the circumference of a child bicycle

In 2 seconds it makes 3 revolutions

It makes the distance of

d = 3*2*37.7 = 226.2 inches in t = 2 seconds

Speed = d/t

Speed is:

226.2/2 = 113 inches/second

An assembly line must create one finished product every 3 minutes. The sum of the task times required to create a product is 700 seconds. What is the theoretical minimum number of workstations for this assembly line

Answers

Answer:

We need 4 workstations configurated in series as minimum to create theoretically a finished product every 3 minutes.

Step-by-step explanation:

At first we assume that assembly line is formed solely by workstations configurated in series. We must keep in mind that theoretical minimum number of workstations is equal to the sum of the task times required to create a product divided by the time taken by the assembly line to create one finished product. That is:

[tex]n = \frac{700\,s}{3\,min\times 60\,\frac{s}{min} }[/tex]

[tex]n = 3.889\,workstations[/tex]

We need 4 workstations configurated in series as minimum to create theoretically a finished product every 3 minutes.

Answers

Answer:

  (p, q) = (16, 20)

Step-by-step explanation:

You can add the two equations together to make one from which q can be eliminated:

  (4p) +(3p -q) = (-q +84) +(28)

  7p -q = -q +112 . . . . simplify

  7p = 112 . . . . . . . . . . add q

  p = 112/7 = 16

Using this value in the second equation, we get ...

  3·16 -q = 28

  48 -28 = q = 20 . . . . . add q-28

The equilibrium point is (p, q) = (16, 20).

Which is greater, 25% of $200 or 80% of 100?

Answers

Answer:

80% of 100

Step-by-step explanation:

25% of something is basically dividing it by 4, meaning 25% of 200 is 50,

While 80% of 100 is 80

A good way to memorize this is if youre taking anything as a percent of 100, get rid of a 0 on the 100, and put a decimal place in the number.

(e.g. 90% of 10 is 9. whereas 90% of 100 is 90)

Just remember which you're dealing with!

Hope this helps!

Answer:

80% of 100 is greater

Step-by-step explanation:

25% of 200 is

0.25*200 = 50

80% of 100 is

0.8*100 =80

As 80 > 50,

As the question does not mention that the interest paid is compounded, simple interest will be used;

what is the equation of the line that is parallel to the given line and passes through the point (2, 3)?​

Answers

Given problems:

    Line parallel that passes through (2,3);

Solution:

To solve this problem, we need to first understand what parallel lines are.

A parallel line is any two line that does not meet at any point.

In order to achieve this, both lines must have the same slope.

 So, we find the slope of the given line and write in the form for a straight line.

 Slope of line  = [tex]\frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]

      let   x₁, y₁ = (-2, -1)

              x₂, y₂ = (2 , -3)

Now input the parameters and solve for the slope;

            Slope of line = [tex]\frac{-3-(-1)}{2- (-1)}[/tex]   = [tex]\frac{-2}{3}[/tex]

Any line that would be parallel to this must have the same slope.

 Equation of a straight line;

                  y  = mx + c;

      y and x are the coordinates;

      m is the slope

      c is the y-axis intercept;

       From  (2, 3);

        y = 3 and x = 2; m = [tex]\frac{-2}{3}[/tex]

     3 = [tex]\frac{-2}{3}[/tex] x 2 + C

     3 = [tex]-\frac{4}{3}[/tex] + C

       C = [tex]\frac{13}{3}[/tex]

 So the equation of the line is;

               y = [tex]\frac{-2}{3} x[/tex]  + [tex]\frac{13}{3}[/tex]

 Multiply through by 3;

              3y = -2x + 13

The equation of the line is 3y = -2x + 13

Damarius is making some big life decisions! He decides it's time to start saving for his future and deposits $300 each month at 4.1% annual interest, compounded monthly, for 30 years. At the end of 30 years, he has an account balance of $211,966.64. How much of this did Damarius contribute and how much of this is interest?

Answers

Answer:

$108,000

$103,966.64

Step-by-step explanation:

Damarius contributes $300 each month, for 30 years. Therefore, to find the amount he contributed, we multiply those pieces together (12 months in each year).

300⋅12⋅30=$108,000

Therefore, over the 30 years, Damarius contributed $108,000.

If there was $211,966.64 in his account, and he contributed $108,000, then the rest is interest.

$211,966.64−$108,000=$103,966.64

There was $103,966.64 in interest earned on Damarius' account.

Last year during the July 4th holiday, Americans ate about 150,000,000 hot dogs. Over the entire year, Americans ate a total of about 2 x 10^10. Compute how many times greater the total number of hot dogs eaten by Americans last year was than the number of hot dogs eaten during the 4th of July holiday. Round your answer to the nearest one.​

Answers

Answer:

133 times

Step-by-step explanation:

First, convert 2 x 10^10 out of scientific notation:

20,000,000,000

Since this is the total amount of hotdogs, divide by the number eaten on July 4th:

20,000,000,000 / 150,000,000 = 133.3333333

Round to nearest one: 133 times

The total number of hot dogs eaten by Americans last year is 133 times greater than the number of hot dogs eaten during the 4th of July holiday.

What is division?

A division is a process of splitting a specific amount into equal parts.

We have,

The number of hot dogs that ate on 4th July holiday= 150,000,000

The number of hot dogs that ate last year = 2 x [tex]10^{10}[/tex]

The number of times the total number of hot dogs eaten last year than the number of hot dogs eaten during the 4th of July holiday is:

Number of hot dogs eaten in July x M = Number of hot dogs eaten in the entire year

150,000,000 x M = 2 x [tex]10^{10}[/tex]

M = 2 x [tex]10^{10}[/tex] / 150,000,000

M = 20,000,000,000 / 150,000,000

M = 133.33

Rounding to the nearest one we get,

M = 133

Thus the total number of hot dogs eaten last year is 133 times greater than the number of hot dogs eaten during the 4th of July holiday.
