What is the percent change of $15.60 to $11.70?
Rashid [163]

Answer:

percentage change=25% .

Step-by-step explanation:

Given : $15.60 to $11.70    .

To find:  What is the percent change .

Solution: We have given that   $15.60 to $11.70  .

Change = final value - initial value .

Change   = $15.60 - $11.70  

                   =$3.9

percentage change = \frac{change}{original value}*100

                                =   \frac{3.9}{15.60}*100

                                =   \frac{390}{1560}*100.

On dividing both number by 3

percentage change=\frac{130}{520}*100.

percentage change=\frac{1}{4}*100.

percentage change=25% .

Therefore, percentage change=25% .

A car is traveling at 20.0 m/s, and the driver sees a traffic light. turn red. After 0.530 s (the reaction time), the driver app
slava [35]
Before the driver applies the brakes ( with the reaction time ):
d 1 = v0 · t = 20 m/s · 0.53 s = 10.6 m
After that: 
v = v0 - a · t1  
0 = 20 m/s - 7 · t1
7 · t1 = 20
t1 = 2.86 s
d 2 = v 0 · t1 - a · t1² / 2
d 2 = 20 m/s · 2.86 s - 7 m/s² · (2.86 s)²/2 = 57.2 m - 28.6 m = 28.6 m
d = d 1 + d 2 = 10.6 m + 28.6 m = 39.2 m
Answer: the stopping distance of a car is 39.2 m.
