Wolfrich vivió en Portugal y Brasil para aprender portugués durante un período de 14 meses. Aprendió un promedio de 130 palabras nuevas por mes cuando vivió en Portugal y un promedio de 150 palabras nuevas cuando vivió en Brasil. En total aprendió 1920 palabras nuevas. ¿Cuánto tiempo vivió Wolfrich en Portugal y cuánto tiempo vivió en Brasil?

Responder:

Portugal = 9 meses

Brasil = 5 meses

Explicación paso a paso:

Dado que:

Total de meses pasados ​​tanto en Brasil como en Portugal) 14 meses

Dejar ;

tiempo pasado en Brasil = b

Tiempo pasado en Portugal = p

Promedio de palabras aprendidas por mes en Brasil = 150

Promedio de palabras aprendidas por mes en Portugal = 139

Total de palabras aprendidas = 1920

Matemáticamente;

150b + 130p = 1920 - - - (1)

b + p = 14 - - (2)

b = 14 - p

De 1)

150 (14 - p) + 130p = 1920

2100 - 150p + 130p = 1920

2100 - 20p = 1920

2100 - 1920 = 20p

180 = 20p

p = 9

b = 14 - p

b = 14 - 9

b = 5

Por lo tanto;

Portugal = 9 meses

Brasil = 5 meses

Sarah made a scale drawing of a dinosaur.
she made the height of a dinosaur 2 1/2 inches.
the actual height of the dinosaur is 9 feet.
what scale did sarah use for her drawing?
1 inch=3.6 ft
1 inch=4.5 ft
1 inch=18 ft
1 inch=22.5 ft

Answers

Answer: The scale used by Sarah is 1 to 43.2 inches ( drawing to actual)

Step-by-step explanation:

Here, we want to know the scale used for the drawing of the Dinosaur by sarah.

The actual height of the Dinosaur is 9 feet, but in her drawing she represented the height by 2.5 inches( 2 1/2 is same as 2.5 inches)

Mathematically, we know that 1 foot is 12 inches;

So the actual height of the Dinosaur is 9 * 12 = 108 inches

So practically, what she has done is to represent a height of 108 inches by 2.5 inches

So the scale factor used will be;

108/2.5 = 43.2

The scale used is 1 to 43.2 or simply 1:43.2 to represent the drawing to the actual

Plays the song every 18 minutes. The other radio station plays the song every 24 minutes. Both stations play the song at 3:00 PM. When is the next time the stations will play the song at the same time?

Answers

Answer:

4.12 PM

Step-by-step explanation:

Radio station 1 : Plays the song every 18 minutes

Radio station 2 : plays the song every 24 minutes

Both stations play the song at 3:00 PM.

When is the next time the stations will play the song at the same time?

Find the lowest common multiple of 18 and 24

18 : 18, 36, 54, 72, 90, 108, 126, 144, 162, 180, 198, 216, 234, 252, 270

24 : 48, 72, 96, 120, 144, 168, 192, 216

The lowest common multiple of 18 minutes and 24 minutes is 72 minutes

72 minutes = 1 hour 12 minutes

Add 1 hour 12 minutes to 3:00 PM to know when both radio station will play the song at the same time

= 3.00 PM + 1 hour 12 minutes

= 4.12 PM

Answers

Answer: $298.97

Step-by-step explanation:

Cost of electronic games = $32.99

Cost of I- pad = $200

Since Ethan decided to purchase 3 electronic games and the l-pad, his total cost will be:

= (3 × $32.99) + $200

= $98.97 + $200

What is Unitary Method?

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

We have,

182 people rode the roller coaster.

307 people rode the roller coaster.

A total of 921 people had ridden the roller coaster.

So, Number of people rode the roller coaster

= 921 - 182 - 307

what is the value of x in the equation 2(x-3)=4(x-4)?

Answers

Answer:

The value of x is 5

Step-by-step explanation:

Let us simplify each side at first

∵ 2(x - 3) = 4(x - 4)

∴ 2(x) - 2(3) = 4(x) - 4(4)

2x - 6 = 4x - 16

→ Subtract 4x from both sides

∴ 2x - 4x - 6 = 4x - 4x - 16

-2x - 6 = -16

→ Add 6 to both sides

∴ -2x - 6 + 6 = -16 + 6

-2x = -10

→ Divide both sides by -2

∴ [tex]\frac{-2x}{-2}=\frac{-10}{-2}[/tex]

∴ x = 5

The sum of two numbers is 75. One number is 5 more than 9 times the other number. What are the two numbers?

Answers

The two numbers are 11 and 64

One number is 5 more than 9 times the other. If we represent the first number with x, we get the two numbers to be

x          and

9+5x

The sum of the two numbers is 75. Plugging the two numbers into that equation, you get

x + 9+5x = 75

You can simplify to get

6x+9 = 75

By subtrating 9 from both sides, you get

6x = 66

Now you are practically done! You just need to divide both sides by 6 to get

x = 11

The two numbers were

x         and

9+5x

By plugging x = 11 into both of the equations, you get

11         and

64                (64 is 55 + 9)

Nita is making a fruit drink. She mixes apple juice and mango juice in the ratio 3 : 1. Apple juice costs 56p for a 1-litre carton. Mango juice costs £1.20 for a 1-litre carton. A pack of 80 plastic cups costs £1. Nita sells her fruit drink at a school concert in 250ml cups for 60p each. She gives all the profit she makes to the school fund. Nita makes 80 cups of the fruit drink and sells them all. How much money does she give to the school fund?

Answers

Answer:

£32.60

Step-by-step explanation:

Nita is making a fruit drink. She mixes apple juice and mango juice in the ratio 3 : 1. Apple juice costs 56p for a 1-litre carton. Mango juice costs £1.20 for a 1-litre carton.

A pack of 80 plastic cups costs £1. Nita sells her fruit drink at a school concert in 250ml cups for 60p each.

We are told that Nita sells all her 80 cups

100 pence = £1

60p =

= 60/100

= £0.6

Hence, the selling price =

£0.6× 80

= £ 48

Profit = Selling Price - Cost Price

We have to find the Cost Price

A pack of 80 plastic cups costs £1.

Nita is making a fruit drink. She mixes apple juice and mango juice in the ratio 3 : 1.

3 + 1 = 4

1 liter = 1000ml

For Apple Juice

3/4 × 1000ml = 750ml

For Mango Juice

= 1/4 × 1000ml = 250ml

This means she uses a mixture of 750 ml of Apple juice and 250 ml of Mango juice

Apple juice costs 56p for a 1-litre carton.

£0.56 = 1 liter = 1000ml

1000ml = £0.56

750 ml =

= 750 × 0.56/1000

= £0.42

Mango juice costs £1.20 for a 1-litre carton.

1000ml = £1.20

250 ml = x

x = 250 × 1.20/1000

= £0.3

Hence, the total cost for 1000ml of mixed juice = £0.3 + £0.42

= £ 0.72

We are told the content of each cup = 250 ml

For 80 cups she would need

80 × 250 ml

= 20000ml of the mixed juice

If 1000 ml = £0.72

20000ml = x

x = 20000 × £ 0.72/1000

x = £14.4

1 pack of 80 cups cost £1

Hence: £14.4 + £1

Cost Price = £15.4

Profit = Selling Price - Cost Price

Profit = £48 - $15.4

Profit = £32.60

Therefore, the money she gives to the school fund is £32.60
