it's D becuase when you round all of them 124.2 is the only one thats different.
124.5 Rounded is, 125
125.3 Rounded is 125
124.9 Rounded is 125
124.2 Rounded is 124
Hope this helps. (i'm doing the same test lol)
Answer:
(2x+2)
Step-by-step explanation:
38 is the correct answer because 80-4=76 then divide that by 76/2 give you 38
Answer:
an = -9 -3(n -1)
Step-by-step explanation:
The explicit formula for an arithmetic sequence with first term a1 and common difference d is ...
an = a1 +d(n -1)
Putting your numbers into the formula gives ....
an = -9 -3(n-1)
The formula for finding the height of an octagon from only one side is h=s(1 + the square root of 2). S is the length of one side. Your formula would be h=18(1 + the square root of 2).
h=18+18(the square root of 2)
h=18 + 25.4558
h=43.4558
Hope this helps!! :) And the decimal is rounded, just so you know ;). If your teacher likes everything in simplest radical form, then just don't convert the 18*the square root of 2 into a decimal and solve as you normally would.
