Arectangle has a width of 9 units and a length of 40 units. what is the length of a diagonal

41 units

Step-by-step explanation:

In this question, you should remember that the diagonal  drawn will represent the longest side of the triangle that will be formed .This is to say the triangle will have the two shorter sides (the length and width) and the longest side (diagonal).

Apply the Pythagorean relationship where

The formula to apply here will be

Diagonal = 41 units

Step-by-step explanation:

It is given that,a rectangle has a width of 9 units and a length of 40 units.

To find the diagonal of rectangle

We know that rectangle can be considered as combination of two right triangles.

Here length of right triangle = 40 units and height = 9 units

Hypotenuse = diagonal of rectangle.

Hypotenuse² = Length² + height

 = 40² + 9²

 = 1600 + 81

 = 1681

Hypotenuse = √1681 = 41

Therefore diagonal of rectangle = 41 units

i used to know but i learned it a long time ago sorry

step-by-step explanation:

$3720

step-by-step explanation:

taxable income = $31000

as per the 2018-2019 us tax bracket, the tax rate is 12% for an individual whose taxable income is between $9,526 to $38,700.

so, the tax to be paid by him = 12% of 31000

= 0.12 * 31000     [12% converted to decimal as 0.12]

= $3720
