0.7 is just 7 tenths which is literally 7/10.
Answer:
you would need to find a number 25,26,27,28... times bigger than the number it self so 2×50=100 which means in decimal from can be 0.25
Step-by-step explanation:
2÷50
Answer:x · 1 + = ___.
1
x
1 + x
2x
Step-by-step explanation:
Ok lets do this like this:
<span>Let x = length
Let y = width
From this we know that area A=xy.
</span><span>Now, perimeter is P=2x+2y
cost would be 3(2x)+2(2y) or 6x +4y=$6,000.00.
From this cost equation we solve for x in terms of y
6x=6000-4y
x=1000-(4y)/6.
</span>now lets substitute this value in the area equation A=xy.
A=(1000-4y/6)y
<span>A=1000y−4<span>y2</span>/6=1000y−2<span>y2</span>/3</span>
differentiate and set to equal zero (0)
<span>1000−(−4y/3)=0</span><span>
Solve for y and obtain y=750ft</span>
