5 grams of salt is equal to (blank) kilograms of salt
Lyrx [107]
1 kilogram=1000 grams
divide both sides by 1000
1/1000 kilograms=1gram

5 grams=5 times 1/1000kilograms
5grams=5/1000kilograms=1/200kilograms
5grams= 5/1000kg=0.005kg

the answer is 0.005kg or 1/200kg

Vivian found data about her city's population and made a scatter plot the equation of the linebbest fit for. Her data is p= 637.
Andre45 [30]

Answer:

annual growth rate m = 637.5 people / year

Step-by-step explanation:

Solution:-

- The scatter plot displaying the city's population was modeled by a linear equation of the form:

                               y = m*x + c

Where, m and c are constants.

- The scatter plot displayed the following relation of the city's population (p):

                               p = 637.5*t + 198,368.1

Where, p : The population in t years after after 1990

            t : The number of years passed since 1990.

- The slope of the graph "m = 637.5" denotes the rate of change of dependent variable with respect ot independent variable:

                             dp / dt = m = 637.5

- So the rate of change of population per unit time t since 1990 has been constant with a an annual growth rate m = 637.5 people / year
