Answer:
a) The blue whale has about 200 times more mass
Step-by-step explanation:
(blue whale mass)/(cow mass) = (1.8×10^5 kg)/(9×10^2 kg)
... = (1.8/9)×10^(5-2)
... = 0.2×10^3
... = 200
The blue whale has about 200 times as much mass as a cow.
We will use the formula for the slope:
m = ( y2- y1 ) / ( x2 - x1 )
For PQ : m = ( 0 - 0 ) / ( a + c - 0 ) = 0
For RS : m = ( b - b ) / ( a - ( 2a + c )) = 0
Both slopes are m = 0, so PQ and RS are parallel to x - axis and at the same time parallel to each other ( PQ | | RS ). One pair of opposite sides is parallel.
Answer:
Step-by-step explanation:
Isn’t this mathematics not science
To find population density, it is population / area.
The population is 6688, divided by the area of 16.
6688/16 = 418
So the population density is 418 people per sq mile.
Answer: a=36; b=18
Step-by-step explanation:
1. You know that the sum of two numbers is 54, then, you have:
a+b=54
2. According to the problem, the larger number is 18 more than the sampler number, this can be expressed as following:
a=b+18
3. Then, you must substitute the second equation into the first equation and solve for b:
b+18+b=54
b=18
4. Then the value of a is:
a+18=55
a=36
