Answer:4.55*10^8 or 4.55 times 10 to the power of eight.
Step-by-step explanation: First put a decimal at the end of the number. 455000000. Then move the decimal point 8 spaces to the right. 4.55000000 this means the power of 10 will be a positive 8.
number part=4.55000000 (which can be written as 4.55) and exponent part =8 The solution is 4.55*10^8
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
Its quite simple. for every white bucket of paint he uses, he uses 3 buckets of black paint as well. so if he made 24 litres of grey paint then he would have had to use 24 buckets of white paint. but, this might be a trick question because its saying he made 24 "litres" but the unit it started with was "buckets" so it might be trying to trick you because we dont know how much paint is in one "bucket"
Subtract y from each side getting you 0=mx+b-y to put it in standard form, but i could be wrong though.
Military discount, I guess...
