I got 14 because if you put 7/1 and then do Keep Change Flip you would get 7/1 times 2/1 and then you would get 14/1 which equals 14
Answer:
1:4
Step-by-step explanation:
3:12
((3×1):(3×4))
=1:4
(would love if you could mark me the brainliest :))
Hello,
we suppos the numbers are 1 and 2.
1+2=3
67-3=64
We must thus add 32 to each number
numbers are 1+32=33
and 2+32=34
(we don't need equation to solve that!)
The answer is 54 square units.
let the vertex in quadrant I be (x,y)
<span>then the vertex in quadratnt II is (-x,y) </span>
<span>base of the rectangle = 2x </span>
<span>height of the rectangle = y </span>
<span>Area = xy </span>
<span>= x(27 - x</span>²<span>) </span>
<span>= -x</span>³<span> + 27x </span>
<span>d(area)/dx = 3x</span>²<span> - 27 </span><span>= 0 for a maximum of area </span>
<span>3x</span>²<span> = 3 x 3</span>² = <span>27 </span>
<span>x</span>²<span> = 9 </span>
<span>x = ±3 </span>
<span>y = 27-9 = 18 </span>
So, the largest area = 3 x 18 = 54 square units
30% times 450 = 135
450 - 135 = 315
