The length of a rectangle is 5 units and its width is 4 units. What is the approximate length of the diagonal of the rectangle?

Inessa05 [86]

Answer:

The approximate length of the diagonal of the rectangle = 6.4 units ⇒ B

Step-by-step explanation:

* Lets revise the properties of the rectangle

- The rectangle has 4 sides

- Each two opposite sides are parallel and equal in length

- It has for right angles

- Its two diagonals are equal in length

- The diagonal divide the rectangle into two congruent right triangles

* Now lets solve the problem

∵ The length of the rectangle = 5 units

∵ The width of the rectangle = 4 units

∵ The diagonal of the rectangle with the length and the width formed

right triangle, the length and the width are its two legs and the

diagonal is its hypotenuse

- To find the length of the hypotenuse use Pythagoras theorem

∵ Hypotenuse = √[(leg1)² + (leg2)²]

∴ The length of the diagonal = √[5² + 4²] = √[25 + 16] = √41

∴ The approximate length of the diagonal of the rectangle = 6.4 units

skelet666 [1.2K]

Answer:

3^7

Step-by-step explanation:

We know that $3^8=3\cdot3^7$ and since it's multiplied by $\frac{1}{3}$ which is the same thing as $\frac{1}{3}^1$ we know that $3\cdot\frac{1}{3}\cdot3^7=3^7$ .

The volume of a cube is 64 cubic inches. Which expression represents s, the length of a side of the cube?

vlabodo [156]

Answer:

<h2>Therefore the length of a side of a cube is $\sqrt[3]{64}\ or\ 4$ </h2>

Step-by-step explanation:

The volume of a cube is expressed as L³ where L is the length of each side of the cube.

Given volume of a cube = 64in³

On substituting;

64 = L³

Taking the cube root of both sides to determine L we have;

$\sqrt[3]{64} = (\sqrt[3]{L})^{3}\\\sqrt[3]{64} = L\\L=4$

Therefore the length of a side of a cube is $\sqrt[3]{64}\ or\ 4$
