Answer:

7in, 7in, and 15 in

Step-by-step explanation:

Based on the Triangle Inequality Theorem that states that the sum of any 2 sides of a triangle must be greater than the measure of the third side, we can find what set of lengths cannot form a triangle.

The only set that does not follow the theorem is the set with lengths 7in, 7in, and 15in. It does not follow the theorem because...

7 + 7 < 15 (which should not be true based on the theorem)

If a car is depreciated in four years, what's the rate of depreciation using twice the straight-line rate?

Ulleksa [173]

Answer:

The rate of depreciation is 50%

Step-by-step explanation:

We are given

a car is depreciated in four years

so, depreciation in 1 year is

$=\frac{1}{4}$

the rate of depreciation using twice the straight-line rate

so, we will multiply by 2 and then we can find rate of depreciation

so, rate of depreciation is

$=2\times \frac{1}{4}\times 100$

$=50$ %
