Answer:
The maximum length of the second piece is 61.5 ft.
Step-by-step explanation:
We know that the rope is 100 ft long.
There are three pieces that make up the 100 ft. The first is length x, the second is three times as long as the first, so it would be 3x, and the third is 18ft.
So if we were to write this as an equation it would look something like this: x + 3x + 18 = 100. We can simplify this some more.
4x + 18 = 100
4x = 82
x = 20.5
Now that we know the length or the first piece / x. We can easily find the length of the second (3x) by plugging in 20.5 for x.
We find that the maximum length of the second piece of rope is 61.5 feet.
Good luck, hope that helps!
Answer:
ACD = 120°
Step-by-step explanation:
Exterior angle theorem.
3x = (x + 12) + (x + 28)
3x = 2x + 40
x = 40
ACD = 3x = 3(40) = 120°
Move all terms to the side of the answer x = -8/7 Hope this helps! ;D
About 1.5 per min but im not sure if it is exactly 1.5
Answer:
-459 2/9
Step-by-step explanation:
calculate 34-99= -65
and turn 2 7/9 into a mixed number as 25/9
leaves u with
7(-65)-7+25/9
multiply 7x-65=-455
-455-7+25/9
-462+25/9
get common denomionator and add
-4133/9 or -459 2/9 or -459.2
