The diagram shows the ratio of teeth on the larger and smaller gears of Nash's fishing reel. A tape diagram showing 6 parts labe

Gre4nikov [31]

Answer:

12 teeth

Step-by-step explanation:

The attachment of this question is missing; however, the question can be solved without the attachment

Given:

Larger Gear = 6

Smaller Gear = 1

Required

Number of Smaller Gear if there are 72 larger gears

When the number of larger gear is 6, smaller gears is 1;

This can be represented using the following ratio;

$6 : 1$

Let x represent the number of smaller gear, when there are 72 larger gears;

This can also be represented using the following ratio;

$72 : x$

Equate both ratios

$6 : 1 = 72 : x$

Convert the ratios to fraction

$\frac{6}{1} = \frac{72}{x}$

Multiply both sides by x

$x * \frac{6}{1} = \frac{72}{x} * x$

$x * 6 = 72$

Divide both sides by 6.

$\frac{x * 6}{6} = \frac{72}{6}$

$x = \frac{72}{6}$

$x = 12$

This implies that there are 12 teeth on the smaller gear

Write a recursive rule for the sequence. 7, 6, 13, 19, 32, ...

allsm [11]

Answer:

recursive rule for the given sequence:

$a_n = a_{n-1}+a_{n-2}$ for n > 2

Step-by-step explanation:

Given the sequence:

7, 6, 13, 19, 32, ......

then;

First term $(a_{1})$ = 7

Second term $(a_{2})$ =6

third term $(a_{3})$ = 13 and so on..

You can see that:

$a_3 = a_1+a_2 = 6+7 = 13$

similarly for:

$a_4 = a_2+a_3 = 6+13 = 19$ and so on..

The recursive rule for this sequence is:

$a_n = a_{n-1}+a_{n-2}$ for n > 2
