Maria uses 2 centimeters of tape for every present she wraps. Write an equation that shows the relationship between the number o
Marizza181 [45]

Answer:

y = 2x

Step-by-step explanation:

Maria uses 2 centimeters of tape for each present she wraps, and we want a equation that shows the relationship between the number of presents x and the tape used y. To do this, we can establish a rule of three with the information given:

1 present wrapped -> 2 centimeters of tape

x presents wrapped -> y centimeters of tape

1/x = 2/y

x = y/2 -> y = 2x

From this relation, we know that to make x presents, Maria will use 2x centimeters of tape.

In 2000, the population of a county was 25,300,987. The population decreased at a rate of 2% each year. What was the population
EastWind [94]

Answer: In 2008 the population was 21,525,144

Step-by-step explanation:

You need to use the following formula for Exponential decay:

P=P_0(1-r)^t

Where P_0 is the initial population in the year 0, r is the rate of decay and t is the time.

In this case, you can identify that:

P_0=25,300,987\\\\r=2\%\\\\t=8

Therefore, substituting these values into the formula for Exponential decay, you get:

P=P_0(1-r)^t\\\\P=(25,300,987)(1-\frac{2}{100})^8\\\\P=21,525,144

Then, in 2008 the population was 21,525,144
