Avi uses 11 toothpicks to form a row of 5 attached triangles, as shown. Suppose he continues this pattern, using 89 toothpicks i
Pavel [41]

Answer:

44

Step-by-step explanation:

Given that Avi used 11 toothpicks to form a row of 5 attached triangles.

Total number of toothpicks used = 89

Let the total number of triangles formed be represented by x, so that:

11 toothpicks = 5 triangles

It would be observed that only the first triangle starting the pattern has 3 toothpicks. So that;

the average number of toothpicks for 1 triangle = \frac{11}{5}

                                  = 2.2

The number of toothpicks per triangle = 2.0

Thus,

x = \frac{89}{2.0}

  = 44.5

x = 44

The total number of triangles formed is 44.

A pancake recipe require 1 2/3 cups of flour to make 20 pancakes and you have 9 cups of flour.
Leokris [45]
<h2>Solution (a) :-</h2>

Quantity of flour needed to make 20 pancakes =

= 1 \frac{2}{3}  \:

=  \frac{3  \times 1 + 2}{3}

=  \frac{5}{3}  \: cups \: of \: flour

Then , number of pancakes that can be made from 1 cup of floor :-

20 \div  \frac{5}{3}

20 \times  \frac{3}{5}

\frac{60}{5}

= 12 \: pancakes .

Therefore , 12 pancakes can be made from 1 cup of floor .

<h2>Solution (b) :-</h2>

Number of pancakes that can be made with 1 cup of flour = 12 pancakes

Number of pancakes that can be made with 9 cups of flour :-

= 9 × 12

= 108 pancakes

Therefore , I can make 108 pancakes with 9 cups of flour .

<h2>Solution (c) :-</h2>

Yes , I have enough flour to make 100 pancakes . I say this because :-

With one cup of flour I can make = 12 pancakes

With 9 cups of flour I can make =

= 9 × 12

= 108 pancakes

As I can make 108 pancakes with 9 cups of flour , I can conclude that I have enough flour to make 100 pancakes .
