the table shows the baseball game attendance for three consecutive nights. About how many people attended the three games?​
irina [24]

Answer:

About 150,000

Step-by-step explanation:

Round because you are finding <u>about </u>how many people attended (I’m just doing it in my way; are multiple ways to round and multiple answers):

52,104 ≈ 52,100

48,899 ≈ 48,900

49,023 ≈ 49,000

Add:

52,100 + 48,900 + 49,000 = about 150,000 people attended

Find the length of the third side. If necessary, round to the nearest tenth. 6 10​
MrMuchimi

Answer:

11.66

Step-by-step explanation:

As far as I remember the Pythagorean theorem states that A squared + B squared = C Squared.   A and B are your 2 input numbers so therefor 6squared + 10squared =136 but you have to find the Square root of that because you added the other two squared numbers. Your anwser is approximately 11.661903.
