80,000,000 = 80,000,000 (in expanded form)
80,000,000 = eighty million (in word form)
80,000,000 = 8 x 10^7 (in standard form)
Answer:
w= −16/t
Step-by-step explanation:
Let's solve for w.
wt = −21+5
Step 1: Divide both sides by t.
tw/t = −16/t
w= −16/t
Area of a rectangle = length (l) * width (w)
A = 30ft * 20ft
A = 600 sq ft
Now the width of a sidewalk that surroundeds it = 3 ft
so now the area of the rectangle with sidewalk= 30+3ft * 20+3ft
A = (33*23) ft
A = 759 sg ft
Area of the sidewalk = 759 - 600
A = 159 sq ft
A= 0.25 or 1/4
Hope this helps:)
I think that first one represents a function.
