300. if you sold a third. then 2/3 would be left. you can then infer each is 300
Louise’s answer is not correct. She is missing the term 30x3. When squaring a binomial, it is best to write the product of the binomial times itself. Then you can use the distributive property to multiply each term in the first binomial by each term in the second binomial. Louise also could have used the formula for a perfect square trinomial, which is found by squaring a binomial.
Answer:
2:1 that is 2 inches in real life is equal to 1 inch in the drawing.
Step-by-step explanation:
We are given the following in the question:
Longest side of the pool = 10 inches
Longest side of the pool in drawing = 5 inches
Scale:
We find the ratio of the real length of pool and the measurement of the length of the pool in the drawing.

Thus, we can say Paco's new drawing follows a scale of 2:1 that is 2 inches in real life is equal to 1 inch in the drawing.
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.

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

Our model then is

This means that for every pound of weight, the dog will get one-fiftieth of a mg of medicine.
step by step explanation:
Draw a perpendicular line AB=6cm
Open your compass to a radius of 4.5cm and place it on B to construct an arc
Again open your compass to a radius of 5.9cm and step at A and draw an arc to intersect the first one at C
Open your compass to a reasonable radius and step at A and B to construct an arc
With the same radius step at B and C to construct another arc
Draw a line to bisect the arcs
