Answer:
9 inches ; 0.7 units ; m units
Step-by-step explanation:
The area of a square is give as :
The square of the side length of the square ; that is ;
Area of square = s² ;
Where s =! Side length of the square
Hence ;
A square with area = 81 in²
Length of its side = sqrt(81) = 9 inches
Area of square = 0.49 unit²
Length of its side = sqrt(0.49) = 0.7 units
Area of square = m² unit²
Length of its side = sqrt(m²) = m units
Answer:
0.056 kilometers
Step-by-step explanation:
The answer is 3.3125 because 5÷16=0.3125 and 0.3125+3=3.3125.
In this problem, we are asked to give an expression that can be used to mentally multiply 6 and 198. In order not to go through the rigorous multiplication, we can estimate 198 to 200, that is 6 *200 equal to 1200. Since there is a 2*6 excess or 12 then we subtract: 1200 -12 equal to 1188.
A^2 + b^2 = c^2.....a and b are the legs and c is the hypotenuse
4^2 + b^2 = 5^2
16 + b^2 = 25
b^2 = 25 - 16
b^2 = 9
b = sq rt 9
b = 3 m
1 meter = 100 cm....so 3 meters = 3(100) = 300 cm
ur answer : the tree is 300 cm high
