Could 8.8 cm, 8.0 cm and 8.8 cm be the side lengths of a triangle?
1 answer:
Answer:
yes it is possible to have a triangle with 8.8 cm, 8.0 cm and 8.8 cm.
Step-by-step explanation:
Condition on sides of triangle:
- The triangle inequality states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.
- It is not possible to have sum to be less than the length of the third side.
- A triangle with three given positive side lengths exists if and only if those side lengths satisfy the given condition
- Let a, b and c be three sides of triangle.
Here, we are given that a = 8.8 cm, b = 8.0 cm, c = 8.8 cm
We check for the triangular inequality:
Thus, yes it is possible to have a triangle with given measurements.

Answer:
146%
Step-by-step explanation:
If the percent change is positive, it is a percent increase.
If the percent change is negative, it is a percent decrease.
Your numbers are
old price = $0.92
new price = $2.26
Plug in the numbers in the formula above and evaluate the expression.
percent change = ($2.26 - $0.92)/($0.92) * 100%
percent change = ($1.34)/($0.92) * 100%
percent change = 1.4565 * 100%
percent change = 146%
Since the percent change is a positive number, it is a percent increase.
Answer: The percent increase is 146%.
