Answer:

209 \frac{3}{4}  -  {3}^{2}  \times (8 {}^{2}  - 38 \frac{1}{2} ) \\  = 209 \frac{3}{4}  - 3 {}^{2}  \times 25 \frac{1}{2}  \\   = 209 \frac{3}{4} - 229 \frac{1}{2}  \\   =  - 19 \frac{3}{4}

In the figure, angle B measures 44°, angle A measures 62°, and angle E measures 50°.
Gre4nikov [31]
We don't need the figure
angle b = 44 degrees
angle a = 62 degrees
angle e = 50 degrees
angle f = unknown
we know that 
angle a + b + e + f = 180 degrees
50 + 44 + 62 + f =180 degrees
f= 180-50-44-62
but here there is only one blank so we have to add 44 and 62 to make one number that is 106
therefore, f = 180-50-106
if you further want to solve it angle f is 24

Rock singer and writer Beep Blair is paid 11.5% on her CD sales and music downloads. Last year, she sold 1.22 million CDs and 2.
Dmitrij [34]

Using proportions, it is found that she earned $943,000 from CD sales.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.

The total amount involved in the sells and downloads are:

1.22 x 5 + 2.1 x 1 = 8.2 million.

She was paid 11.5% of that, hence:

0.115 x 8.2 = 0.943 million = $943,000.

She earned $943,000 from CD sales.

A gym initially has 5000 members. Each year, the gym loses 10% of its current members and gains 100 new members. Which recursive
Elis [28]

Answer:

An = A0 + 100 * n - (An-1) * 0.10

Step-by-step explanation:

Tenemos una regla recursiva para una secuencia es una fórmula que nos dice cómo avanzar de un término a otro en una secuencia. Por lo tanto debemos buscar a An.

Hay un valor inicial que es 5000, una ganancia y una perdida de clientes, que podemos representar así:

An = 5000 + Ganancia - Perdida

Inicial = A0 = 5000

Ganancia = 100, pero cómo sucede cada año, sería: 100 * n

Perdida = 10% de los miembros actuales, si al principio son 5000 por lo tanto A0 * 0.10, pero en este primer caso es que es A0, pero en general serían An-1

reemplazando:

An = A0 + 100 * n - (An-1) * 0.10
