Answer:
So I don't know the equation but I know the answer.
Length: 170 ft.
Width: 100 ft.
Step-by-step explanation:
The perimeter (The length all around) is 270. You do the perimeter divided by two and add 35, because we know they are almost equal except for one side is 35 ft. longer, That is your length. You the take the perimeter minus the length to get the width.
Equationish: P÷2= x+35= y -> P-y=w
Or: 270÷2= 135+35=170 -> 270-170= 100ft.
Answer:
+ 
i
Step-by-step explanation:
Using the exact value
cos60° = 
and sin60° = 
, then
3(cos60° + isin60°)
= 3( + i) ← distribute by 3
= + i ← in the form a + bi
Answer:
65.8
Step-by-step explanation:
(2.6*4.7)/2=6.11
11*4.7=51.7
(4.7(17-(2.6+11)))/2=7.99
6.11+51.7+7.99=65.8
Answer:
see the explanation
Step-by-step explanation:
we have
0.888...
This is a <u>repeating decimal</u> (Is a decimal that has a digit, or a block of digits, that repeat over and over and over again without ever ending)
Convert to fraction number
Let
x=0.888...
10x=8.888...
Subtract 0.888... from 8.888... to remove the decimal
10x-x=8.888...-0.888...
9x=8
Solve for x
x=8/9
therefore
Mike fraction is incorrect
because 4/5=0.8
0.8 is a <u>terminating decimal </u>(It's a decimal with a finite number of digits)
Mike's mistake was considering the number as a terminating decimal instead of a repeating decimal
Beth is correct
because
If you divide 8/9
the result is 0.8888888...
