The annual average high temperature in a town was 50° in the year 2008 and
55° in the year 2009. What was the percent increase in average high
temperature in this town between the two years?

Answers

Answer 1

Given:

The annual average high temperature in a town was 50° in the year 2008.  

The annual average high temperature in a town was 55° in the year 2009.

To find:

The percent increase in average high temperature in this town between the two years.

Solution:

The percent increase formula:

[tex]\%\text{ Increase}=\dfrac{\text{New value - Initial value}}{\text{Initial value}}\times 100[/tex]

Substitute new value = 55 and initial value = 50 in the above formula.

[tex]\%\text{ Increase}=\dfrac{55-50}{50}\times 100[/tex]

[tex]\%\text{ Increase}=\dfrac{5}{50}\times 100[/tex]

[tex]\%\text{ Increase}=\dfrac{1}{10}\times 100[/tex]

[tex]\%\text{ Increase}=10[/tex]

Therefore, the temperature in this town between the two years increased by 10%.

Answer:

[tex]Y=\frac{c}{a}-\frac{b}{a}[/tex]

Step-by-step explanation:

Answer:

y=c+b/a (The a is under c+b)

Step-by-step explanation:

Add the b over to c.

ay=c+b

Now divide both sides by a, which will remove the a from y.

y=c+b/a

Find the Perimeter of the figure below, composed of a rectangle and two semicircles.
Round to the nearest tenths place.
8.

Answers

Answer:

Perimeter of given figure = 28.56 unit (Approx.)

Step-by-step explanation:

Given:

Length of long side = 8 unit

Number of long side = 2

Diameter of semi circle = 4

Number of semicircle = 2

Find:

Perimeter of given figure

Computation:

Radius of semi circle = Diameter of semi circle / 2

Radius of semi circle = 4 / 2

Radius of semi circle = 2 units

Perimeter of given figure = 2[πr] + 2[Length of long side]

Perimeter of given figure = 2[(3.14)(2)] + 2[8]

Perimeter of given figure = 2[6.28] + 16

Perimeter of given figure = 12.56 + 16

Perimeter of given figure = 28.56 unit (Approx.)

Joanne puts 40 bacteria in a petri dish. The population of bacteria is doubling every hour. Which function best represents the situation?

Answers

Key points:

In exponential growth, a population's per capita (per individual) growth rate stays the same regardless of population size, making the population grow faster and faster as it gets larger.
In nature, populations may grow exponentially for some period, but they will ultimately be limited by resource availability.
In logistic growth, a population's per capita growth rate gets smaller and smaller as population size approaches a maximum imposed by limited resources in the environment, known as the carrying capacity (
K
KK).
Exponential growth produces a J-shaped curve, while logistic growth produces an S-shaped curve.

j would be 130 cuz sides that are congruent have congruent angles so you add those two angles up and subtract from 180

Answer:

Step-by-step explanation:

There is 180 degrees in a triangle so you would do 25 + 25 + x = 180
