Answer:

Option D

Step-by-step explanation:

<u><em>Using Unitary Method:</em></u>

10 rotations = 1 minute

=> 1 rotation = 1/10 minute

Multiplying both sides by 43.5

=> 43.5 rotation = \frac{43.5}{10} minutes

=> 43.5 rotation = 4.35 minutes

Construct a rectangle whose one side is 3 cm and a diagonal equal to 5 cm.​
VMariaS [17]

Answer:

Length = 4 cm

Breadth = 3 cm

Step-by-step explanation:

Its Simple, We use The Pythagoreas theorem,

We know that the Hypotenuse of a triangle squared is equal to the sum of the legs square,

So  A^2 + B^2 = C^2

substitute the values,

    3^2 + B^2 = 5^2

     9 + B^2 = 25.

Subtract 9 from both sides

    B^2 = 25 - 9

    B^2 = 16

     B = sqrt[16] = 4

I am assuming that you are not asking for an actual construction of a rectangle on paper, but if you are, just ask

ss7ja [257]

The slope is 9/11 because if you use the formula (change in y)/(change in x), you would get -18/-22 and then if it were to be simplified, it would be 9/11
