Answer:
a=0.1
Step-by-step explanation:
From the given frequency table, Fiction= Poetry+Prose=total
⇒0.2+0.8=1.0=total
And, Poetry+prose= total
⇒0.18+0.82=1.0= total
Thus, following the same path,we have
Non Fiction= Poetry+prose=Total
⇒a+0.9=1.0
⇒a=1.0-0.9
⇒a=0.1
Therefore, the value of a will be: 0.1
You can factor -80 as
So, we have
The square root of a product is the product of the square roots:

Answer:
Front: 33 ft
Back: 66 ft
Step-by-step explanation:
Let w be the width of the front yard
½[w + 2w]×2w = 3300
3w² = 3300
w² = 1100
w = 33.1662479036
w = 33 ft
2w = 66 ft
Use KMF (Keep multiply flip)
keep the first fraction as it is
