Answer:

\large\boxed{23^o20'48''=\left(23\dfrac{26}{75}\right)^o}

Step-by-step explanation:

\text{We know:}\\\\1^o=60'\to1'=\left(\dfrac{1}{60}\right)^o\\\\1'=60''\to1^o=(60)(60'')=3600''\to1''=\left(\dfrac{1}{3600}\right)^o\\\\23^o20'48''\\\\20'=\left(\dfrac{20}{60}\right)^o=\left(\dfrac{1}{3}\right)^o\\\\48''=\left(\dfrac{48}{3600}\right)^o=\left(\dfrac{1}{75}\right)^o\\\\\text{Therefore}\\\\23^o20'48''=23^o+20'+48''=23^o+\left(\dfrac{1}{3}\right)^o+\left(\dfrac{1}{75}\right)^o\\\\=\left(23+\dfrac{1\cdot25}{3\cdot75}+\dfrac{1}{75}\right)^o=\left(23+\dfrac{25}{75}+\dfrac{1}{75}\right)^o=\left(23\dfrac{26}{75}\right)^o

Jimmy is building a rectangular fence for his back yard. If the perimeter of the fence is 300 feet and the width 20 feet longer
IRISSAK [1]

Answer:

Length-65 ft   Width: 85

Step-by-step explanation:

Let's set the length as x, and the width as x+20 (because it is 20 ft longer than length)

We know that 2L+2W=Perimeter

We can substitute x and x+20 in for 2L and 2W, and 300 for Perimeter

New Equation: 2(x) +2(x+20)=300

After Distribution: 2x+2x+40=300

Combine like terms: 4x+40=300

Subtract 40 from both sides: 4x=260

Divide 4 on both sides and you get x=65 (Length)

Add 20 to get width : x+20= 85

I hope it helped! :)
