answer is option D

because you can divide them like

\frac{2}{10}  =  \frac{1}{5}  \\  \\  \frac{4}{20}  =  \frac{1}{5}  \\  \\  \frac{6}{30}  =  \frac{1}{5}  \\  \\  \frac{8}{40}  =  \frac{1}{5}

so the option is D

A standard doorway measures 6 feet 8 inches by 3 feet. What is the largest dimension that will fit through the doorway without b
nikdorinn [45]

Answer:

87.73 inches

Step-by-step explanation:

We are given that the dimensions of the rectangular doorway are,

Length = 6 ft 8 inches = 80 inches and Width = 3 feet = 36 inches.

Using Pythagoras Theorem, we will find the diagonal of the rectangular doorway.

i.e. hypotenuse^{2}=length^{2}+width^{2}

i.e. hypotenuse^{2}=80^{2}+36^{2}

i.e. hypotenuse^{2}=6400+1296

i.e. hypotenuse^{2}=7696

i.e. Hypotenuse = ±87.73 inches

Since, the length cannot be negative.

So, the length of the diagonal is 87.73 inches.

As, the largest side of a rectangle is represented by the diagonal.

So, the largest dimension that will fit through the doorway without bending is 87.73 inches.

The ratio of three numbers are 2:3:4.

Let the rational between the three numbers be x, hence the three numbers be 2x, 3x,and 4x.


If their average is 36, what are the numbers

We know the average = sum of the numbers / no. Of numbers.

(2x+3x+4x) /3=36

9x/ 3= 36

3x =36

X= 36/ 3

X= 12

The rational is 12
