I believe it's 12 because 5*16=80. So, then you would subtract 4 from 16 and gat 12.

The number of milligrams of a certain medicine a veterinarian gives to a dog varies directly with the weight of the dog. If the
Andre45 [30]

Answer:

Step-by-step explanation:

A direct variation equation is of the form

y = kx,

where, in words, it reads "y varies directly with x" or "y varies directly as x". In order to use this as a model, we have to have enough information to solve for k, the constant of variation. The constant of variation is kind of like the slope in a straight line. It rises or falls at a steady level; it is the rate of change.

We have that a vet gives a dose of three-fifths mg to a 30 pound dog. If the dose varies directly with the weight of the dog, then our equation is

d = kw and we need to find k in order to have the model for dosing the animals.

\frac{3}{5} =k(30)

Divide both sides by 1/30 to get k alone.

(\frac{1}{30})(\frac{3}{5})=k and

k=\frac{1}{50}

Our model then is

d=\frac{1}{50}w

This means that for every pound of weight, the dog will get one-fiftieth of a mg of medicine.

The length of a rectangle is increased by 25% , but the width of the rectangle is decreased by 25%. By what percent was the rect
Yuki888 [10]

The rectangle's area decreased by 19%.

Length = L

Breadth = B

Original area = L x B

New area = A = L x (1 + 25%) x B x (1 - 25%)

A = L x B x 0.25 x 0.75 = L x B x 1.05

Therefore the area of the rectangle has decreased by 19%.

To find the location of a rectangle, multiply its width by means of its height. If we understand the sides of the rectangle which are different lengths, then we have each the height and the width.

The perimeter P of a rectangle is given through the system, P=2l+2w, wherein l is the period and w is the width of the rectangle. The area A of a rectangle is given by means of the method, A=lw, in which l is the duration and w is the width.
