We need to know the density of Marble City, hence we know the density of Pebble City.
MC density = population/area
MC density = 52,348/125
MC density = 418.784 people/miles

From the question, we know that the two cities have the same population density.
PC density = MC density
PC density = 418.784 people/miles

Use the density formula to figure out the dimension of PC
PC density = population/area
418.784 = 85,312/(l × w)
(l × w) = 85,312/418.784
11.8 w = 85,312/418.784
11.8 w = 203.7
w = 203.7/11.8
w = 17.2

The closest value of x is 17 miles

There are 86400 frames of animation in 1 hour of anime.How many frames are there per second
Sveta_85 [38]

Answer:

There are 24 frames of animation in 1 second of anime.

Step-by-step explanation:

There are 60 seconds in 1 minute, and 60 minutes in 1 hour. 60×60=3600, so there are 3600 seconds in 1 hour.

Since 3600 seconds and 1 hour is the same, there are 86400 frames of animation in 3600 seconds of anime. To find out how many frames are in one second of anime, divide 86400 by 3600.

86400 ÷ 3600 = 24

There are 24 frames of animation in 1 second of anime.

If f(x) = x^2 and g(x) = 1/2x + 3, find g(f(-1)).<br> A.) -1<br> B.) 1/25<br> C.) 1/5<br> D.) 1
Veseljchak [2.6K]
F(x)=x^2
x=-1→f(-1)=(-1)^2→f(-1)=1

g(x)=1/(2x+3)
g(f(-1))=g(1)→x=1→g(1)=1/[2(1)+3]=1/(2+3)→g(f(-1))=1/5

Answer: Option C.) 1/5
