What is the measure of angle B in the triangle?

this triangle is not drawn to scale.

### Answers

40°+B+C = 180° (sum of angles in a triangle)

sub. in values of B and C :

40° + (2x-30)° + (x+20)° = 180°

expand the equation and solve for x:

2x + x + 40° - 30° + 20° = 180°

3x + 30° = 180°

3x = 150°

x = 50°

sub. x = 50° into B,

2(50°) - 30° = 100° - 30°

= 70°

B = 70°

La factura de celular del mes pasado ascendió a un total de $239 por un consumo de 269 minutos de llamada, mientras que la de este mes ascendió a $175 por un consumo de 141 minutos. El importe es la suma de una tasa fija (renta de línea) más un precio fijo por minuto. Calcular la tasa y el precio por minuto

### Answers

**Answer:**

Costo fijo= $104.5

Costo unitario= $0.5 por minuto

**Step-by-step explanation:**

Mes pasado:

$239 por 269 minutos

Mes corriente:

$175 por 141 minutos

**Primero debemos calcular el cost por minuto de llamada:**

**Costo unitario= (costo total más alto - costo total más bajo) / (cantidad de minutos más alto - cantidad de minutos más bajo)**

Costo unitario= (239 - 175) / (269 - 141)

Costo unitario= $0.5 por minuto

**Ahora, el costo fijo:**

**Costo fijo= costo total más alto - (costo unitario*cantidad de minutos más alto)**

Costo fijo= 239 - (0.5*269)

Costo fijo= $104.5

**Costo fijo= costo total más bajo - (costo unitario*cantidad de minutos más bajo)**

Costo fijo= 175 - (0.5*141)

Costo fijo= $104.5

**Answer:**

18.64 miles

**Step-by-step explanation:**

There are 1.609344 km per mile, so the distance traveled in 1 second is ...

(30 km)(1 mi)/(1.609344 km) ≈ 18.64 mi

**The Earth travels around the Sun at the rate of about 18.64 miles per second**.

**Answer:**

18.64 if rounded

**Step-by-step explanation:**

First you need to know how many miles is 1 kilometer. That would be approximately 0.62137 miles. Multiply this by 3 and you would get 1.86411. Now multiply this by 10 to make it 30 kilometers worth of miles and not 3 kilometers. You would get 18.6411 which rounded to the hundredths place would be 18.64.

It is defined as the **relation** between two **variables**, if we plot the** graph **of the linear **equation** we will get a **straight** line.

If in the linear **equation**, one variable is present, then the **equation** is known as the **linear **equation in one **variable**.

It is given that:

Solve for y P=2x+2y+4

From the **data** given in the question:

The **linear** equation is:

P=2x+2y+4

To solve for make the subject as y:

2y = P - 2x - 4

y = (1/2)[P - 2x - 4]

Or

y = P/2 - x - 2

Thus, the **equation** can represent as y = P/2 - x - 2 after solving for y if the **equation** is P = 2x + 2y + 4.

Answer: 47 degrees

Step-by-step explanation:

The measure of an **angle** BOC from the given figure is 47°.

What is an angle?

An **angle** is formed when two straight lines or rays meet at a common endpoint. The common point of contact is called the vertex of an angle.

Given that, m∠AOC is a straight angle, m∠BOC=6x+29° and m∠AOB=3x+124°.

We know that, a **straight angle** measures 180°.

Now, m∠BOC+m∠AOB=m∠AOC

6x+29°+3x+124°=180°

9x+153°=180°

9x=27°

x=3°

So, m∠BOC=6x+29°

=6×3+29°

= 47°

Therefore, the measure of **angle** BOC is 47°.

3. You have saved $140 for a new pair of skis. They have a regular price of $189. They have been reduced by 30%. There is a 13% tax as well. a. What is the discount? b. What is the new price? c. What is the tax? d. What was the total price of the shoes, after the discount and tax? e. Do you have enough money?

### Answers

Answer:

$56.70

$132.30

$17.199

$149.499

No

Step-by-step explanation:

Given that:

Regular price of skis = $189

Discount % = 30%

Amount saved = $140

After sales tax = 13%

a. What is the discount?

Discount amount = Regular price * discount %

Discount amount = $189 * 0.30

Discount amount = $56.70

b. What is the new price?

Regular price - Discount amount

$189 - $56.70

= $132.30

c. What is the tax?

Sales tax = new price * tax %

Sales tax = $132.30 * 0.13

Sales tax = $17.199

d. What was the total price of the shoes, after the discount and tax?

New price + sales tax

= $132.30 + $17.199

= $149.499

e. Do you have enough money?

No

$149.499 > $140

One of the slowest fish is the blenny

fish. The function y = 0.5x describes

how many miles y the fish swims in

x hours. Graph the function. Use the

graph to estimate the number of miles

the fish swims in 3.5 hours.

.

### Answers

**Answer:**

It swims 1.75 miles in 3.5 hours. X stands for hours so x=3.5. Y stands for miles so y=1.75.

**Step-by-step explanation:**

your equation is y=0.5x

we know x=3.5

so y= 0.5(3.5)

solve and you get y= 1.75

so in (x,y) intercept format (3.5,1.75) and you can make a graph and label your x intercepts hours and your y intercepts miles traveled.

The number of miles the fish swims in 3.5 hours is **1.75 miles**.

The equation of a straight line is:

**y = mx + b**;

**y, x** are variables,** m** is the **slope** of the line and **b** is the **y intercept**.

Given the function: y = 0.5x;

where **y** represent the **miles** the fish swims in **x hours**.

The graph of the function is plotted using geogebra online graphing tool.

From the graph, the number of miles the fish swims in 3.5 hours is **1.75 miles**.
