Answer:</h2><h2>
The expected number of people who will attend this concert = 2260</h2>
Step-by-step explanation:
The concert organizers estimate people will attend if it is not raining = 19000
If its raining people will attend = 4000
On the day of the concert, meteorologists predict a 90% chance of rain.
This means 10 % chance of not raining
The expected number of people = 90% (4000) + 10% (19000)
= 360 + 1900
= 2260
The expected number of people who will attend this concert = 2260
Answer:
87
Step-by-step explanation:
If you look at the numbers upside down they are 86, 88, 89, 90 and 91 so the number that is covered by the car is 87.
This situation is a right triangle with the base measuring 18 and the hypotenuse 22. We are looking for x, the height up the pole that the wire is going to be attached to. We will use Pythagorean's Theorem to find the missing length.

and

. x^2 = 160 so x =

or 12.65 feet
you need to distribute the 5. multiply each term in the parentheses by 5:
5(1) + 5(3x)
5 + 15x
