El área de un decágono regular cuya apotema mide 5,08 cm y la longitud de su lado es 3,3 cm.
jeyben [28]

Answer:

83.82 cm^2

Step-by-step explanation:

Aquí, queremos calcular el área de un decágono dada su apotema y la longitud de su lado.

Matemáticamente;

Área de decágono = 1/2 * perímetro * apotema

Donde perímetro = 10 * s

donde s es la longitud de los lados

Entonces el área aquí sería; 1/2 * 10 (3.3) * 5.08 = 83.82 cm ^ 2

Sam runs for 10 minutes The graph shows his puse, in beats per minute. 100- (beats per min) 80- 1 2 3 5 6 7 8 9 10 Time (min) By
Inessa05 [86]

The rate at which his pulse is increasing after 3 minutes is 9.5 beats per minute

<h3>How to determine the beat rate after 3 minutes?</h3>

The given graph shows the curve and the tangent.

From tangent line, we have the following points:

(x,y) = (3,119) and (1,100)

The beat rate (m) at this point is:

m = \frac{y_2 -y_1}{x_2 -x_1}

So, we have:

m = \frac{100 - 119}{1 - 3}

Evaluate the differences

m = \frac{-19}{-2}

Evaluate the quotient

m = 9.5

Hence, the rate at which Sam's pulse is increasing after 3 minutes is 9.5 beats per minute

HELP ASAPJennifer and Chris completed some chores and split the earnings in the ratio 3:2. Jennifer earned $48.
elixir [45]

Let the total earnings be = x

Jennifer and Chris split the earnings in the ratio 3:2

Jennifer earned = $48

\frac{3x}{5}=48

3x=240

x=80

Hence total earnings are $80

(a) Chris earning is = \frac{2x}{5}=\frac{2*80}{5}=32

Hence, Chris earns $32

(b) Jennifer spends 30% of her earnings on a book.

So, price of the book = \frac{30}{100}\times48

Price of book = $14.40

(c)  Jennifer also buys a magazine for = $5.40

So, total money Jennifer spent on book and magazine = 14.40+5.40=19.80

Money left with Jennifer = 48-19.80= $28.20

In fractions = \frac{28.20}{48}

or multiplying the numerator and denominator by 10, we get

\frac{282}{480}=\frac{47}{80}

(d) Let the original price of the shirt = x

reduction percentage on x= 40%

Price paid after reduction = 16.80

\frac{40x}{100}=16.80

40x=1680

x=42

Hence, the original price of the shirt was $42.
