Step-by-step explanation:
Answer:
85 units^2 = Area of Blue Square
and
x = 5 units
Step-by-step explanation:
To do this we use the Pythagorean theorem (a^2 + b^2 = c^2). a and b represent the legs of the triangle whereas c represents the longest side of the triangle, or the hypotenuse.
Since we know the area of a square is the side length multiplied by itself (or the side length squared),
is the side length of the pink square and
is the side length of the green square.
That means a =
and b =
, so...

35 + 50 = c^2
85 = c^2

Now we need to square the square root of 85 to find the area of the blue square.

85 units^2 = Area of Blue Square
To solve the other question we use the same formula again.

x = 5 units
Answer:
a) 
b) The pollution level at 4 o'clock in the afternoon is of 280 parts per million.
Step-by-step explanation:
The pollution level in the center of a city at 6 am is 30 parts per million and it grows in linear fashion by 25 parts per million every hour.
This means that the pollution in t hours after 6 am is given by:
, which is the answer to question a.
b. The pollution level at 4 o'clock in the afternoon
4 in the afternoon is 10 hours after 6 am, so this is y(10).

The pollution level at 4 o'clock in the afternoon is of 280 parts per million.
Answer:
x = 20/3
Step-by-step explanation:
When 10 is subtracted from 3 times the number and the number is divided by 2, what is the number? ---> 3 ( x / 2) - 10 = 0
3 ( x / 2) - 10 = 0
3( x / 2 ) = 10
3x / 2 = 10
3x = 10 * 2
3x = 20
x = 20/3
