Step-by-step explanation:
The change in weather is a continuous phenomenon but the climate of a place remains more or less the same year after year. Weather is a state of atmosphere at a particular time and is determined by wind condition, atmospheric pressure.
Let the side of one square be x. Area = x*x = x²
Then the side of other square would be 2x , Area = 2x*2x = 4x²
Combined area = x² + 4x² = 5x²
This combined area = 45 cm²
Therefore 5x² = 45 Divide both sides by 5
x² = 45/5
x² = 9 Take square root of both sides
x = √9
x = 3
Length of larger square is 2x = 2*3 = 6 cm
Length of larger square = 6cm
Hello,
First, 42 goals in 76 games can be written as the following proportion:
42/76
Next, after finding 42/76, multiply by 100% to have the probability that Sidney would get his first goal in the first game.
42/76 * 100% = 55% (rounded)
Good luck to you!

We know there were 21 vehicles so one of the equations is:
c+b=21
We can find the second equation with the other given information:
30b+4c=318
We can use manipulate the first equation then use substitution to solve the system:
c=21-b
We can plug this into the second equation:
30b+4(21-b)=318
30b+84-4b=318
26b+84=318
26b=234
b=9
Now we can plug this into one of the original equations to solve for c (the first equation is easier):
c+9=21
c=12
You can check your work by plugging the answers into the two equations:
12+9=21
21=21
(30)(9)+(4)(12)=318
270+48=318
318=318
There are 9 buses and 12 cars.
