How many boards, each 3/4 yd long, can be cut from a piece of wood that is 6 yards long? Will there be any wood left over?

Answers

Answer 1
Answer: Since 3/4 is 0.75, let’s use it like that.
6/0.75=8
Since the answer does not have any decimals, no wood will be left over.

A rectangle is eight inch long and its diagonal is ten inches. What's the width of the rectangle?

Answers

Diagonal = \sqrt{length^(2) + width^(2) }

10 = \sqrt{8^(2) + width^(2) }

10 = \sqrt{64 + width^(2) }

100 = 64 + width^(2)

width^(2)\n = 100 - 64

width^(2) = 36

width = √(36)

width = 6 inches

Answer:

the answer is 6 inches

Step-by-step explanation:

To find the diagonal we use the Pythagorean Theorem:

l² + w² = d² where the is d hypotenuse

8² + w² = 10²

64 + w² = 100

w² = 100 - 64

w² = 36

w = √36

w = 6

therefore the width of the rectangle is 6 inches

4. Think about it, it would mean that 4 is the result of 0.4 (40%) multiplied by a number. Therefore, you would divide 4 by 0.4. The answer would be 10.
5. To do this, multiply 0.2 by 700. This gives you 140.
6. Think about it, what percent of 25 is 12. Divide 12 by 25, then multiply by 100 and add a percent sign after it. 12/25 is 0.48. Multiply that by 100 to get 48%.

The following 3-D object is composed of identical cubes. The volume of the 3-D object is 56cm cubed. The surface area of the 3-D object is 
a) 30cm squared
b) 60cm squared
c) 120cm squared
d) 144cm squared

Answers

There are 7 equal cubes by inspection that make up the shape.

Each cube has a volume of: (56 cm^3)/7 = 8 cm^3

To find side dimension of cube (knowing a cube is the 3D extrusion of a square meaning all sides are equal:

s = (side dimension) = (8 cm^3)^(1/3) = 2 cm

Also by inspection, there are 5 exposed faces on 6 of the 7 cubes. To find the total surface area, multiply number of exposed faces per cube by the surface area of a single face:

S.A. = 5(6)(2*2) = 120 cm^2

The correct answer is C). 120cm squared
