Step-by-step explanation:
The truck does 3 sides of the square 3 x 24 = 72
and the truck does one entire diagonal of the square
with side lengths 24
diagonal = sqrt (24^2 + 24^2 ) = 33.94 miles
total miles 33.94 + 72 = 105.94 miles in 4.5 hours
105.94 / 4.5 = 23.54 m/hr for the entire trip
The mph for the actual driving time (2.5 hours )
105.94 / 2.5 = 42. 38 m/hr for driving time only
In the 2nd digit is worth 300. In the 3rd digit it is worth 30.
Answer:
x+3
Step-by-step explanation:
sqrt(x^2+6x+9)
factor
We know this is a perfect square trinomial
sqrt(( x+3)^2)
Taking the square root of a square
x+3
10=2×5 and 14=2×7 so least common denominator will be 2×5×7=70
9/10=63/70
3/14=15/70
So 63/70-15/70=48/70=24/35
Step-by-step explanation:
Pythagoras (for right-angled triangles) :
c² = a² + b²
c being the Hypotenuse, the side opposite of the right angle. and that would be here the diagonal.
c = diagonal = 10 ft
therefore, the width of the rectangle is 10/2 = 5 ft
10² = 5² + b²
100 = 25 + b²
b² = 75
b = length = sqrt(75) = 8.660254038... ft
