Answer:

Step-by-step explanation:

Pythagorean theorem: In a right angle triangle, the square of hypotenuse is equal to the sum of squares of other two sides

BC² + AB² = AC²

5² + AB² = 13²

25 + AB² = 169

AB² = 169 - 25

AB² = 144

AB = √144 = √12*12

AB = 12cm

Art [367]

Answer:

$17 \le t \le 28$

Step-by-step explanation:

Given

$t = 22\frac{1}{2}$ --- average time

$\triangle t = 5\frac{1}{2}$ --- the variation

Required

The inequality to represent the scenario

To do this, we simply add and subtract the variation from the average time.

i.e.

$t \± \triangle t$

So, the inequality is:

$22\frac{1}{2} - 5\frac{1}{2} \le t \le 22\frac{1}{2} + 5\frac{1}{2}$

Solve:

$17 \le t \le 28$
