Answer:
That's an isosceles right trapezoid. The legs equal hypotenuse * (1 / sq root (2))
legs = 7 * 1 / sqroot (2)
Answer is D
Step-by-step explanation:
(3x+2) (x-7)
FOIL
first 3x*x = 3x^2
outer 3x*-7 = -21x
inner = 2*x = 2x
last 2*-7 = -14
add them together = 3x^2 -21x+2x -14
combine like terms 3x^2 -19x -14
Answer:
Mr. Drew needs 167.3 ft of wood
Step-by-step explanation:
we know that
The area of a square is
where
b is the length side of the square
we have
substitute in the formula and solve for b
square root both sides
To determine the total length of wood , calculate the perimeter of the sandbox
The perimeter of the sandbox is equal to the perimeter of 5 squares
so
substitute the value of b
therefore
Mr. Drew needs 167.3 ft of wood

Answer:
The volume of the bucket is 122.52 cm³.
Step-by-step explanation:
Given : A frustum is a cone with the end chop off a bucket in the shape of a frustum has diameters of 10 cm and 4 cm at its ends and a depth of 3 cm.
To find : Calculate the volume of this bucket ?
Solution :
The diameters of frustum is
D=10 cm ⇒ R= 5 cm
d=4 cm ⇒ r= 2 cm
The height is h=3 cm
The volume of the frustum is given by,
Substitute the value in the formula,
Therefore, the volume of the bucket is 122.52 cm³.
