¿Cuántas libras de café “La Finca” que se vende a $5 la libra debe mezclarse con 80 libras decafé común que se vende a $2 la libra, para hacer una mezcla que se venda a $3 la libra?

Answers

Answer 1

Answer:

Necesitamos agregar 40 libras del café La Finca

Step-by-step explanation:

Sea x el número de libras de café de La Finca a mezclar.

Entonces, la cantidad total de libras que obtendremos en la mezcla será (x + 80) libras.

Ahora trabajemos con los precios; Tenemos x libras de La Finca a $ 5 por libra, con 80 libras de café a $ 2 por libra para dar una mezcla de (x + 80) a $ 3 Así, sumaremos el precio de La Finca más la otra variante para llegar al costo de la nueva mezcla.

Matemáticamente;

5 (x) + 2 (80) = 3 (x + 80)

5x + 160 = 3x + 240

5x -3x = 240-160

2x = 80

x = 80/2 x = 40

In a sample fruit basket, there are 2 apples for every 3 oranges.
To make a large fruit basket with the same ratio using 20 apples, how many oranges are needed?


Help me please?!

Answers

Answer:

B 32

Step-by-step explanation:

30 oranges would be required to maintain the same ratio with 20 apples.

Solving linear equation.

In the example fruit basket, there are 2 apples for every 3 oranges, based on the provided ratio.

We must establish a proportion in order to determine how many oranges are required to keep the same ratio with 20 apples.

Let "x" stand for the required quantity of oranges.

The ratio can be configured as follows:

20 apples/x oranges = 2 apples/3 oranges.

Cross-multiplication allows us to find the value of "x":

3(20) = 2x

2x = 60

x = 30

As a result, 30 oranges would be required to maintain the same ratio with 20 apples.

Answers

The missing part of the question is;

What is the projected number of people aged 65 and over with Alzheimer's disease in 2030 and in 2050

Answer:

In 2030, P(20) = 7.9536 (in millions)

In 2050, P(40) = 13.2688 (in millions)

Step-by-step explanation:

We are given that;

Number of people aged 65 and over in the U.S. population with Alzheimer's disease (in millions) as;

P(t) = −0.0002083t³ + 0.0157t² – 0.093t + 5.2 (4 ≤ t ≤ 40);

Where t is measured in years and t = 4 corresponds to the year 2014.

Now,

Since t = 4 represents 2014,therefore;

t = 20 would represent population in 2030

Thus in year 2030;

P(20) = −0.0002083(20)³ + 0.0157(20)² – 0.093(20) + 5.2

P(20) = 7.9536 (in millions)

Also, in year 2050, t will correspond to 40 years.

Thus;

P(40) = −0.0002083(40)³ + 0.0157(40)² – 0.093(40) + 5.2

P(40) = 13.2688 (in millions)

A cupcake shop earns $950 a day. The total amount of earning varies directly with the number of days. Find the total earnings the cupcake shop earns in 5 days.

Answers

The correct answer is $4750

Explanation:

If the money earned varies directly with the number of days, this means one factor makes increase the other. In other others, the more days, the higher the earnings. Moreover, the total earnings can be calculated by multiplying the amount earned in one day ($950) by the total days (5). The process is shown below.

Total earnings = Amount earned by day x days

Total earnings= 950 ×5

Total earnings= $4750

Answers

Answer:

Step-by-step explanation:the first one is 8

1) There are total 16 possible outcomes.

2) There are 6 possible outcomes for spinning two numbers that have sum greater than 5.

3) There are 4 possible outcomes for spinning the same number twice.

What is probability?

" Probability is a branch of mathematics which represents the all possibilities. It is defined as the ratio of total number of favourable outcomes to the total number of outcomes of the particular event."

According to the question,

A spinner is divided into 4 equal sections that is 1 to 4.

As per the diagram,

All possible outcomes are as follow:

{ (1 ,1), ), (1,2), (1,3), (1,4), (2,1),  (2,2), (2,3), (2,4), (3,1), (3,2), (3,3), (3,4),(4,1),(4,2),(4,3), (4,4) }

1)  Total possible outcomes = 16

2) Possible outcomes for spinning two numbers that have sum greater than 5 are (2,4), (3,3), (3,4), (4,2), (4,3), (4,4)

Therefore,

Total Possible outcomes for spinning two numbers that have sum greater than 5 = 6

3) Possible outcomes for spinning the same number twice are (1,1), (2,2), (3,3), (4,4)

Therefore,

Total Possible outcomes for spinning the same number twice = 4

Hence,

1) There are total 16 possible outcomes.

2) There are 6 possible outcomes for spinning two numbers that have sum greater than 5.

3) There are 4 possible outcomes for spinning the same number twice.

Rey is considering buying shares of TWA stock. The stock currently sells for $50 per share. The stock changes in value at 9:00 am each day, either increasing in value by $11 or decreasing in value by $13. The stock will increase in value with 40% probability, and decrease in value with 60% probability. The stock follows a random walk. In two days, what is the probability that the TWA stock is greater than $30

Answers

Answer: 64%

Step-by-step explanation:

Given the following :

Current price of stock = $50

Probability of increase per day = 40% = 0.4

Probability of decrease = 60% = 0.6

Value of increase = $11

Value of decrease = $13

Probability that stock is greater than $30 in two days :

For stock to be greater than $30 in two days ;

It either increases in both days or increases in a day and falls the other

Hence, probability that stock is greater than $30

P(increase and increase) OR P(increase and decrease) OR P(decrease and increase)

(0.4 × 0.4) + (0.4 × 0.6) + (0.6 × 0.4)

0.16 + 0.24 + 0.24 = 0.64

0.64 × 100 = 64%

MO bisects LMN mLMN = 8x-23 and mLMO= 2x+37 solve for x and find LMN

Answers

Answer:

see explanation

Step-by-step explanation:

Since MO bisects ∠ LMN then

∠ LMO and ∠ NM0 are congruent, thus

∠ LMN = ∠ LMO + ∠ NMO , substitute values

8x - 23 = 2x + 37 + 2x + 37 = 4x + 74 ( subtract 4x from both sides )

4x - 23 = 74 ( add 23 to both sides )

4x = 97 ( divide both sides by 4 )

x = 24.25

Thus

∠ LMN = 8x - 23 = 8(24.25) - 23 = 194 - 23 = 171°

There are nine different positions on a baseball team. If a team has 17 players how many different line-ups can the team make? (Assume every player can play every position.) The team can make different line-ups. Baseball games consist of nine innings. A team wants to change its line-up every inning. If no game goes to extra innings, and a season consists of 147 games, how many complete seasons can the team play without repeating a line-up? The team can play complete seasons without repeating a line-up. (Your answer should be an integer.)

Answers

Answer:

A) 24310

B) 18 seasons

Step-by-step explanation:

A) We are given the team has 17 players and there are 9 different positions in the team.

This is a combination question and thus, the number of different line-ups the team can make is;

C(17, 9) = 24310

B) We are told the basketball games consists of 9 innings.

Thus,

Number of games you can fill = 24310/9 = 2701.1111

And then we are told a season consists of 147 games.

Thus;

Number of complete seasons can the team play without repeating a line-up =
