Answer:
The answer is -32
Step-by-step explanation:
Multiply both sides by 8 to cancel 8 as the denominator and you have T = -32
In the end, Wally makes $2 (profit)
-$5,+$6,-$7,+$8
Answer:
a = 254.5 mm² ( if using accurate value of π)
a = 254.4 mm² (if using 3.14 as approximate value of π)
Step-by-step explanation:
a = πr²
a = π * 9²
a = π * 81
(note using π = 3.1415926536)
a = 254.4690049408
Rounded
a = 254.5 mm²
(a = 254.4 If using π = 3.14)
8ft by 12ft and 10ft by10ft
If it's just the 7 that's repeating, let
<em>x</em> = 0.1777...
Then
10<em>x</em> = 1.777...
100<em>x</em> = 17.777...
100<em>x</em> - 10<em>x</em> = 17.777... - 1.777...
90<em>x</em> = 16
<em>x</em> = 16/90 = 8/45
If both 1 and 7 are repeating, let
<em>x</em> = 0.171717...
Then
100<em>x</em> = 17.171717...
100<em>x</em> - <em>x</em> = 17.171717... - 0.171717...
99<em>x</em> = 17
<em>x</em> = 17/99
