Answer:

\begin{array}{cc}\text{Nimber of chairs}&\text{Number of screws}\\ \\2&24\\6&72\\9&108\end{array}

Step-by-step explanation:

Gary needs 24 screws for every 2 chairs he builds.

Equivalent unit rate:

Gary needs 12 screws for each chair he builds.

Using this unit rate, we can state that

  • Gary needs 72 screws for every 6 chairs he builds;
  • Gary needs 108 screws for every 9 chairs he builds.

So, the table is

\begin{array}{cc}\text{Nimber of chairs}&\text{Number of screws}\\ \\2&24\\6&72\\9&108\end{array}

Answer:

72 screws are required to make 6 chairs.

108 screws are required to make 9 chairs.

Step-by-step explanation:

We are given the following in the question:

Gary needs 24 screws for every 2 chairs he builds.

We calculate the equivalent ratio to calculate number of screws required.

Ration of chairs to screws can be calculated as:

\displaystyle\frac{\text{Number of chairs}}{\text{Number of screws}} = \frac{2}{24} = \frac{1}{12} = 1:12

This can be interpreted hat 1 chair needs 12 screw.

We have to find number of screws required to make:

1. 6 chairs

Let x be the number of screws required to make 6 chairs, the we can write,

\displaystyle\frac{6}{x} = \frac{1}{12}\\\\x = 6\times 12 = 72

72 screws are required to make 6 chairs.

2. 9 chairs

Let y be the number of screws required to make 9 chairs, the we can write,

\displaystyle\frac{9}{y} = \frac{1}{12}\\\\y = 9\times 12 = 108

108 screws are required to make 9 chairs.

A city held a bike parade. 52 bikers rode in the parade, and 8 of them rode a fixed-gear bicycle.
Vedmedyk [2.9K]

Answer:

\frac{2}{13}

Step-by-step explanation:

Find the probability by dividing the number of fixed gear bikers by the total number of bikers in the parade.

Since there are 8 fixed gear bikers and 52 bikers in total, this will be found by dividing 8 by 52.

So, the probability as a fraction is \frac{8}{52}

This can be simplified by dividing both the numerator and denominator by 4:

= \frac{2}{13}

So, the probability is \frac{2}{13}

The equation is

3(x+3) = 4(x-3)

x = 21 mph

The distance = 3*(21+3)= 72 miles
