The ratio of the number of minutes Arnold lifted weights to the total number of minutes is 1:2 or 1 / 2.
An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value.
Given:
Arnold full workout consist of 10 minutes of warm-up exercises, 25 minutes of lifting weights, and 15 minutes on the treadmill,
Calculate the total time of the work-out as shown below,
Total time of workout = Time of warm-up exercises + Time of lifting weights + Time on the treadmill
Total time of workout = 10 + 25 + 15
Total time of workout = 50 minutes,
Calculate the ratio of the number of minutes he lifted weights to the total number of minutes as shown below,
The ratio of the number of minutes he lifted weights to the total number of minutes = Time of lifting weights / Total time of workout
The ratio of the number of minutes he lifted weights to the total number of minutes = 25 / 50
The ratio of the number of minutes he lifted weights to the total number of minutes = 1 / 2.

By calculation, deduce whether triangle ABC is a right-angled triangle
Answer:
ΔABC is not a right- angled triangle
Step-by-step explanation:
Given AB = 8, BC = 5
Then AC = 22 - (8 + 5) = 22 - 13 = 9 cm
Using the converse of Pythagoras' identity
If the square of the longest side equals the sum of the squares of the other 2 sides then triangle is right.
AC² = 9² = 81
AB² + BC² = 8² + 5² = 64 + 25 = 89
81 ≠ 89, hence ΔABC is not right- angled
