There was a tree that had 6 times a apples on it. 16 apples were rotten. If b=how many apples are still on the tree, then how many apples are left?
The total length around the circle = 2 pi r = 2*pi*16 = 32 pi
Total degrees around the circle = 360 so
length of the arc of measure 270 = 32 pi * 270/360 = 24 pi units
or 75.40 units to the nearest hundredth
Answer:
$4
Step-by-step explanation:
Quick tip about 20% tips.
Move the decimal over 1 place to the left and multiply by 2.
For this equation it would look like this:
18.37 ---> 1.837
(1.837)(2) = 3.674
So, if we rounded to the nearest dollar like the question is asking then we round to $4.
Another way to do this is to multiply 18.37 by .20:
(18.37)(.20) = 3.674
Either way it is $4.

Answer:
2x +3y=1⇒equation 1
3x=2y+8
3x-2y=8⇒equation 2
by elimination method,
2x+3y=1 ×2
3x-2y=8 ×3
4x+6y=2
9x-6y=24
cut 6y and -6y
4x+6y=2
9x-6y=24
---------------
13x+0=26
13x=26
x=26/13
x=2
substitute x=2 in equation 1
2(2)+3y=1
4+3y=1
3y=1-4
3y=-3
y=-3/3
y=-1
therefore, x=2 and y=-1
