If you divide each number by the previous one, you get:

-86 / -172 = 1/2
-43 / -86 = 1/2
-21.5 / -43 = 1/2

The common ratio is 1/2 = 0.5

A family built a house in a beach resort area. In 1990, the house was 430 ft from the water. With erosion, the house was 400 ft
neonofarm [45]

We develop an equation for the given situation by first writing the general equation for lines,

                                y = mx + b

Substituting to this given the values given above,

(1990)                      430 = b

(2000)                      400 = m(10) + 430

The value of m from the equation in 2000 is -3. Thus, the equation of that relates the variables is,

                              y = -3x + 430

Heera jogs 2 rounds of the park, whose length is 4.5 km and width is twice its length .Find the total distance covered by her .
Marizza181 [45]

Answer:

54 km

Step-by-step explanation:

The distance she covers would be equal to twice the perimeter of the park which is in the shape of a rectangle

perimeter of a rectangle = 2 x (length x width)

length = 4.5

width = 2 x 4.5 = 9

2 x (4.5 + 9) = 27km

In one walk, she covers a distance of 27km. In two walks, she covers a total distance of 27km x 2 = 54km
