Although the square root of 2 times the square root of 14 does equal the square root of 28, it is not simplified to the fullest extent. To simplify separate the square root of 28 into two factors, but make sure one is a perfect square. We can separate into 4 and 7, and since the square root of 4 is 2, we are left with 2* the square root of 7

Answer:

$x1 = 3 \\ y1 = 10 \\ x2 = 5 \\ y2 = 12 \\ y - y1 = \frac{y2 - y1}{x2 - x1} (x - x1) \\ y - 10 = \frac{2}{2} (x - 5) \\ y = x - 5 + 10 = x + 5$

Sheila has 12 1/2 pounds of potato salad. She wants to divide the potato salad into containers, each of which holds 2 1/4 pounds

NeX [460]

Answer:

6 containers needed

Step-by-step explanation:

Given

$Total = 12\frac{1}{2}\ lb$ ----- Size

$Container = 2\frac{1}{4}\ lb$ ----- Size

Required

Determine the number of containers needed

This question illustrates the knowledge of fraction and division.

To get the number of containers needed, we simply divide the total size by the size of the container as follows;

$Number = Total/Container$

$Number = 12\frac{1}{2}/2\frac{1}{4}$

Convert to improper fractions

$Number = \frac{25}{2}/\frac{9}{4}$

$Number = \frac{25}{2}*\frac{4}{9}$

$Number = \frac{100}{18}$

$Number = 5.5555556$

$Number = 6$ --- Approximated
