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>

Midpoint (-10,9), (3,8)
solniwko [45]

Answer:

(-3.5 8.5)

Step-by-step explanation:

Midpoint Formula: (\frac{x2 + x1}{2}, \frac{y2 + y1}{2})

What I did: -10 + 3 = 7, 7 / 2 = 3.5 x = 3.5 | 9 + 8 = 17, 17 / 2 = 8.5

Midpoint = (-3.5, 8.5)
