1) The normal room temperature is said to be about 20°C

2) 5 day is equivalent to 120 hr

3) 756 m³/s is equivalent 56000 L/s

4) It would take the snail 5 hours to crawl 75 m

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

1) The normal room temperature is said to be about 20°C

2) 1 day = 24 hr

5 day = 5 day * 24 hr per day = 120 hr

3) 1 m³ = 1000 L

756 m³/s = 56 m³/s * 1000 L/m³ = 56000 L/s

4) 1 m = 100 cm

75 m = 7500 cm

Time = 7500 / (25 cm/min) = 300 min = 5 hours

The initial population of a town in the year 2010 was 20 000. By 2014, the population had grown exponentially to 32 500 people.
stiv31 [10]

Answer:

  P = 20000×1.625^(n/4)

Step-by-step explanation:

An exponential equation can be written using the given data:

  value = (initial value)×(growth factor in period)^(n/(period))

Here, the growth is by a factor of 32500/20000 = 1.625, and the period is 4 years. Then your exponential equation is ...

  P = 20000×1.625^(n/4)

nataly862011 [7]

Answer:

Infant mortality will reduce to 33% in 1.63 years

Step-by-step explanation:

Let the population be X

Population after 1 year

X - 7.3 % of X

X -0.073 X\\0.927X

As we know

P = P_0 * e^{rt}

Substituting the given values we get -

\frac{P_0 - 0.33P_0}{P_0} = e^{-0.33 * t}\\0.67 = e^{-0.33 * t}\\

Taking log on both sides we get -

-0.20273 = -0.33 * t\\t = 1.627

Harley is riding her bicycle 9.88 miles from her house to work. If she rides at a speed of 13 miles per hour, how long will it t
PIT_PIT [208]

It would take Harley 46 minutes to arrive at work.

Step-by-step explanation:

Given,

Distance from house to work = 9.88 miles

Speed of bicycle = 13 mph

Distance = Speed*Time

Time = \frac{Distance}{Speed}

Time = \frac{9.88}{13}

Time = 0.76 hour

We know that 1 hour = 60 minutes

0.7 hours = 60*0.76

0.7 hours = 45.6 minutes

Rounding off to nearest whole minute

0.7 hour = 46 minutes

It would take Harley 46 minutes to arrive at work.
