Answer:
67
Step-by-step explanation:
because the total amount is 180.
so there is 23 +90+x=180so find the number the number is 67
23+90+67=180
133.875
This is the answer because we are given the length and the width of this floor. We are assuming it is a regular rectangle.
So we just multiply the length and the width which is 12.74 x 10.5, which comes out to 133.875
For this case we have that by definition, the slope of a line is given by:

Where:
and
are two points through which the line passes
According to the statement we have:

Substituting we have:

Thus, the slope of the line is:

Answer:

Well first do this
12.00 - 9.30 = 2.30
2.30 + 6.30 = 9
You slept 9hrs
B.) 37.5.. First you place all the numbers in order from least to greatest. Your mean is 25...and ur upper quartile because the 4 #'s fall even u add 35 and 40 and divide by 2... Which gives u upper quartile of 37.5 and lower quartile of 9. Hope this helps :)
