The last one is right because it’s per 1 unit or in this case day
The answer is 1 over 15
Hope it helped!!
At first sight of the denominator on the right, g^2-16, we know that g=4 and g=-4 are not admissible.
To confirm, cross-multiply,
3(g^2-16)=(g+2)(2g+8)
Expand and simplify,
3g^2-48=2g^2+12g+16
g^2-12g-64=0
Solve by factoring,
(g-16)(g+4)=0
so g=16 or g=-4.
Since g=-4 will give a zero denominator on the right-hand side, it is inadmissible, and hence extraneous.
Answer:
0.17 people / sq ft
Step-by-step explanation:
1 If a rectangular pool is 15 feet long and 8 feet wide and there are 20 people in the pool; what is the density of people in the pool?
1.3 people per square foot.
2.5 people per square foot.
06 people per square foot.
.17 people per square foot.
Density of people in pool is number of people per square foot.
area = length * width = 15 ft * 8 ft = 120 ft^2
density = people/sq ft = 20 people / 120 sq ft = 0.17 people / sq ft
