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.
2.25 miles in 1 day
1day=2.25mi
14days=x miles
1day 14days
_______ = ________
2.25mi x mi
Cross multiply
1x=31.5
divide both sides by 1
x=31.5miles
Answer=31.5miles
Answer:
Always
Step-by-step explanation:
A mononomial's variable can only have exponents 0,1,2,3 etc so the product will also be a mononomial.
Equation: 21+n=43.23
Process to find n
21+n=43.23
Subtract 21 from both sides
n=22.23
