A pet survey found that the ratio of dogs to cats is
2
5
. Which proportion shows the number of dogs if the number of cats is 140?

Ok so i hope this helps you.

There are 56 dogs when the number of cats is 140.

Step-by-step explanation:

The ratio of dogs to cats:

\frac{2}{5}

The other proportion:

\frac{x}{140}

\frac{2}{5} = \frac{x}{140}

5 times 28 is 140.

Multiply the fraction by the appropriate form of 1

\frac{2}{5} * \frac{28}{28} = \frac{56}{140}

There are 56 dogs when the number of cats is 140.

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
