rounded to the nearest 100 is 800
Step-by-step explanation:
It will cost $33.
Since wood cost $ .60 sq ft, you can assume she needs to buy 55 sq ft because she will need to buy enough to have 54.3 square ft.
55 x $ .60 = $33
$32.58 would be he total for the 54.3 sq ft and .42 cents would be for the left over .7 sq ft that she didn’t use
Answer:
-3
Step-by-step explanation:
log 1/3 27= 1/3^x=27 this means we have to simplify it. 1/3= 3^-1 power. Thus, (3^-1)^x=3^3. This is equal to 3^-x=3^3 therefore x=-3
2.5 pounds or exact fraction 5/2 or 2 1/2 if you want a mixed fraction
Answer:
y=-1/5x-8/5
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-2-(-1))/(2-(-3))
m=(-2+1)/(2+3)
m=-1/5
y-y1=m(x-x1)
y-(-1)=-1/5(x-(-3))
y+1=-1/5(x+3)
y=-1/5x-3/5-1
y=-1/5x-3/5-5/5
y=-1/5x-8/5
