Answer:
736x-89
Step-by-step explanation:
i think all you can do here is add the numbers that have an X in them so adding 689x+47x=736x and you leave the 89 so it becomes 736x-89
Assuming that the numbers haven't been rounded off, then yes, they are the same.
<h2>
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:
13.9 in
Step-by-step explanation:
Use the Pythagorean Theorem to answer this. Folding the paper along its diagonal produces two triangles; each one has shorter side 8.5 in and longer side 11 in. According to the Pyth. Thm., (8.5)^2 + 11^2 = 193.25, which results in the diagonal length √193.25, or approx. 13.9 in.
