Fiona planted tomato plants in her back yard earlier this year. So far, they have produced 55 tomatoes. From past experience, sh
Harrizon [31]

if we deffine the first week as w₁ = 55, the recursive relation that tells us the number of tomatoes on week n will be:

wₙ = 55 + (n - 1)*14

<h3>How to find the recursive formula?</h3>

We know that, at the moment, the tomato plants produced 55 tomatoes, so that is our first element.

We also know that the tomato plants give 14 tomatoes each week, so in week 2 the number of tomatoes is:

w₂ = 55 + 14

On week 3:

w₃ = 55 + 14 + 14

And so on, so if we deffine the first week as w₁ = 55, the recursive relation that tells us the number of tomatoes on week n will be:

wₙ = 55 + (n - 1)*14

A carpenter has a board that is 2/3 yard wide. He cuts the board into 5 pieces. If all the pieces are the same width, how wide i
hichkok12 [17]

Answer:

\huge\boxed{\frac{2}{15} \text{        yards}}

Step-by-step explanation:

We have a board that is \frac{2}{3} yards long. If we want to cut the board into 5 <em>equal pieces</em>, we must divide \frac{2}{3}  by 5.

\frac{2}{3} \div 5

5 is the same thing as \frac{5}{1}, so:

\frac{2}{3} \div \frac{5}{1}

To divide a fraction by a fraction, we multiply by the reciprocal.<em> </em>This means we take the reciprocal of \frac{5}{1} and multiply the two fractions.

The reciprocal of \frac{5}{1}  is \frac{1}{5} - we swap the numerator and denominator.

\frac{2}{3} \cdot \frac{1}{5}

Multiply the numerator and denominators to get our final fraction:

2\cdot 1 = 2\\3 \cdot 5 = 15\\\\\frac{2}{15}

Hope this helped!
