Decibel is directly proportional to number of cars passing the point. That is,
69 db ----- 139 cars
x db ----- 17 cars
x = number of cars passing the point per minute on a weekend.
Then,
x= (69*17)/139 = 8.43 db ≈ 8 db
Answer:
Step-by-step explanation:
For obects already in motion, the distance travelled, s, is:
s = vi*t + (1/2)at^2
where vi is the initial velocity, a is the acceleration, and t is the time in seconds.
We want the time, t, to reach 1000 meters.
1000 m = (3 m/s)*t + (1/2)*(0.1m/s^2)*(t^2)
(1/2)*(0.1m/s^2)*(t^2) = 0.05t^2
0.05t^2 + 3t -1000 = 0
Solve quadratic equation:
t = 114.6 seconds
Answer:
The slope of line for given points is 
Step-by-step explanation:
Given points of line as :
A = ( - 7 , 15 ) i, e 
= - 7 , = 15
B = ( 10 , 27 ) i.e 
= 10 , 
= 27
Let The slope of line be m
So , The slope with two points is given as equation
m = 
Or, m = 
Or, m =
Hence The slope of line for given points is . Answer
AFB, the sides are similar
Answer:
150 students were not accepted.
Step-by-step explanation:
The ratio right now is 2 to 5 you would need to find an equal ratio with 250 as the second number. 5 is a factor of 250 because if you do 5 x 50 you get 250. So you would multiply 2 by 50 as well which is 100. The ratio is 100 to 250 with 100 being the students being accepted and 250 being the total number of people that applied. Though the question is asking for those that did <em>not</em> pass. If 100 people passed then everyone else out of 250 didn't and 250 - 100 is 150.
