In a square all 4 sides are equal, so when you cut it along the diagonal to make a triangle, both the base and the height of the triangle would be the same.
The area of a triangle is found by the formula 1/2 x base x height
Since the base and height are the same the formula becomes Area = 1/2 x S^2 ( where S is the length of a side).
The area is given as 0.72 square units.
Now you have 0.72 = 1/2 x S^2
First multiply both sides by 2:
1.44 = S^2
To find S, take the square root of both sides:
S = √1.44
S = 1.2
The side length is 1.2 units.
Answer:
8. 14 for the third question.
9. 18 for the forth question.
Step-by-step explanation:
the third and forth orange equations.
The curves cross at coordinates (x, y) = (1, 4). The x-value is said to represent the increase in temperature, while the y-value is said to represent the numbers of visitors and those and who leave early.
The "solution" is the temperature change at which the number of visitors is equal to the number who leave early.

Answer:
The answer is the CD was for 3 years.
Step-by-step explanation:
First, write the equation.
I=Prt
Next, substitute the given values.
$198=$1,200×5.5%×t
Next, write the percent as a decimal.
$198=$1,200×0.055×t
Next, simplify.
$198=$66×t
Then, solve for t.
3=t
