There is a 5 x 6 garden with a 2 feet wide walkway that goes around it. So, there are 2 feet on each side of the the 5 x 6.
5+2+2 = 9
6+2+2 = 10
Now we have a 9 x 6 and the parameter would equal
9*2 + 6*2
18 + 12 = 30 feet of fencing
So we would need 30 feet of fencing.
Answer:
The height is 0 when it "drops".
3/2x + 9 = 0
3/2x = -9
3 = -9(2x)
3 = -18x
3/-18x
Change signs, time cant be negative.
x= 6
Another interpretation; Slope is negative it is falling. This interpretation is more accurate.
-3/2x + 9 = 0
-3/2x = -9
-3 = -9(2x)
-3 = -18x
6 = x
AFTER 6 SECONDS
Answer:
B
Step-by-step explanation:
A rate is a special ratio in which the two terms are in different units. A rate is a little bit different than the ratio, it is a special ratio. For this case, the rate would have units of miles per minutes. We calculate as follows:
rate = 36 miles / 45 min = 0.8 miles per min
distance traveled = 0.8 miles per min ( 60 min ) = 48 miles
Just divide by 12 because they're are 12 inches in a foot. 240 ÷ 12 = 20
