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: +$45
Step-by-step explanation: if his actual pay for the week was $100 then from the question he incorrectly calculated it as {$100 + $45} = $145 which is $45 above his actual pay.
Error = measured value - actual
value.
= $145 -$100 =$45.
NOTE: since the value he assumed{$145} is greater than his actual pay{$100}, we have to include a positive sign to the error{$45}.
Therefore, Error = +$45.
Not a function.
if there are two of the same x-intercept (which make a vertical line). If there is, then it is NOT a function.
If this helps mark me brainliest please!!
What is the area the sprinkler can water?
Area = π r²
r = 18 feet
r² = r * r = 324
A = 3.14 * 324
A = 1017.36
A = 1017 square feet
