Zubin has two pieces of string. One piece is 36 inches long and the other is 48 inches long. He wants to cut them into equal pie
skelet666 [1.2K]

Answer:

12 pieces each:

S_1 = 3\ in

S_2= 4\ in

Step-by-step explanation:

Given

S_1 = 36\ in -- first string

S_2 = 48\ in --- second string

Required

Determine the number of equal pieces

To do this, we first calculate the HCF of the length of both pieces (36\ and\ 48)

36 = 2 * 2 * 3 * 3

48 = 2 * 2 * 2 * 2 * 3

Common\ prime\ factors = 2, 2\ and\ 3

The HCF is:

HCF = 2 * 2 * 3

HCF = 12

<em>Hence, he can cut both strings to 12 pieces each</em>

<em></em>

<em>Recall that </em>

S_1 = 36\ in

<em>The first string can then be cut in to 3 inches each (i.e. 36/12)</em>

S_2 = 48\ in

<em>The first string can then be cut in to 4 inches each (i.e. 48/12)</em>

Fine the following when a=-2, b=4, c=7<br> 7b-12 over 2ac
iren [92.7K]
Hello!

You have to put the numbers in for the variables in the equation

\frac{7b - 12}{2ac}

Put the numbers in

\frac{7(4) - 12}{4(-2)(7)}

Combine like terms

\frac{28 - 12}{-56}

\frac{16}{-56}

The is is \frac{16}{-56} or about -0.29

Hope this help!
