Let the number be x. Then 1.25x = 325, or x = 260.
20% less than 260 is 0.80(260) = 208
Answer: 3v^2w^2 + 10v^2w^3 (or the first option on the screen)
D because u have to look the fraction
The ball will bounce 72 cm high if dropped from a height of 120 cm
<u>Solution:</u>
Given, The height that a ball bounces varies directly with the height from which it is dropped.
A certain ball bounces 30 cm when dropped from a height of 50 cm.
We have to find how high will the ball bounce if dropped from a height of 120 cm?
Now, according to given information,
When dropped from 50 cm ⇒ bounces 30 cm
Then, when dropped from 120 cm ⇒ bounces "n" cm
Now by Chris cross method, we get,
Hence, the ball bounces 72 cm high.
, in a simple interest context, where "n" equals the periods of time and "i" equals the interest rate valid for that periodicity.
. In this case, PV=$15,000; final value equals FV=$15,000+1,687.5= $16,687.5.
. Dividing both sides by 15,000, then subtracting 1 both sides, and finally dividing by 0.075 both sides, results in n=1.5.
