Four and eleven hundreths
Answer:
The length is 12metres, the width is 6metres
Step-by-step explanation:
Suppose the width is x, the length is x+6
The square is 72. The square of rectangular field is equal to product of length and width.
so x(x+6)=72
x^2+6x-72=0
a=1 b=6 c=-72
D= b^2-4ac= 6*6+288= 36+288= 324
sqrtD= 18
x1= (-b-sqrtD)/2a=(-6-18)/2= -12 (it is negative, but width is only positive. So this root doesn't match)
x2=(-b+sqrtD)/2a= (-6+18)/2= 12/2=6 - the width
The length is 6+6=12
Answer:
1/25
Step-by-step explanation:
45 meters is equal to 4500cm
4500 divide by 180 is 25
So, 180 is equal to one over 25
(One twenty-fifth)
Answer:
13) (-5,1)
Step-by-step explanation:
Answer: Raja needs 150.72 cubic centimeters for each horn.
Step-by-step explanation:
Since the horns that Raja is making are cone shaped, then we would determine the amount of clay she needs by applying the formula for
determining the volume of a cone is expressed as
Volume = 1/3πr²h
Where
h represents the height of the cone.
r represents the radius of the cone
π is a constant whose value is 3.14
From the information given,
Height = 16 centimeters
Diameter = 6 centimeters
Radius = diameter/2 = 6/2 = 3 centimeters
Therefore,
Volume = 1/3 × 3.14 × 3² × 16 = 150.72 cubic centimeters
