Answer 2

Answer:

Hi!

a)

1/6 is smaller than 1/2.4/7 is greater than 1/2.1/6 is smaller than 4/7.

b)

5/9 is greater than 3/8.

Step-by-step explanation:

If you are having problems doing the comparision, the best form to check if a number is greater or smaller than another, you can divide the fraction and obtain the decimal form.

Example:

1/6 ≅ 0.16.

4/7 ≅ 0.57.

1/2 = 0.50.

3/8 ≅ 0.37.

5/9 ≅ 0.55.

Now, you can replace the numbers and check again:

0.16 is smaller than 0.5.4/7 is greater than 0.5.0.16 is smaller than 0.57.

b)

0.55 is greater than 0.375.

Convert the improper fraction into a mixed number. 6 1/8 divided by 1 3/4

Answers

Answer:

4 19/32

Step-by-step explanation:

convert into improper fractions

6 1/8= 49/8

1 x 3/4= 3/4

49/8 x 3/4 = 147/32

reduce into mixed number

4 19/32

Final answer:

To convert the mixed numbers 6 1/8 and 1 3/4 to improper fractions, resulting in 49/8 and 7/4, respectively. Then, perform the division as multiplication with the reciprocal of the second fraction, which yields 3 1/2.

Explanation:

Firstly, it's essential to convert the mixed numbers into improper fractions. The given mixed numbers are 6 1/8 and 1 3/4. We can convert 6 1/8 to an improper fraction by multiplying 6 (the whole number) by 8 (the denominator) and then adding 1 (the numerator) to get 49/8. With 1 3/4, we multiply 1 (the whole number) by 4 (the denominator), then add 3 (the numerator), which gives us 7/4.

Now, the division 49/8 ÷ 7/4 can be performed. To divide fractions, we multiply the first fraction by the reciprocal of the second. Therefore, we will multiply 49/8 by 4/7. The result is 196/56. This simplifies to 3 1/2 when converted back to a mixed number.

f(n+1)=f(n)+7
Write a linear equation that

Answers

Answer:

[tex]f(x) = 7x + 30[/tex]

Step-by-step explanation:

We need at least two points to write the equation of a straight line.

The recursive formula that Elijah wrote is:

[tex]f(0) = 30[/tex]

[tex]f(n + 1) = f(n) + 7[/tex]

When we substitute n=0, we get:

[tex]f(0 + 1) = f(0) + 7[/tex]

[tex]f(1) = 30 + 7[/tex]

[tex]f(1) = 37[/tex]

The points (0,30) and (1,37) lies on this line.

The equation of this line is of the form:

[tex]f(x) = mx + b[/tex]

where b =30 is the y-intercept and m=7 is the slope.

We plug in these values to get:

[tex]f(x) = 7x + 30[/tex]

Note that the slope of the line is equal to the common difference of the Arithmetic Sequence.

You could also use the two points to find the slope:

The lengths of nails produced in a factory are normally distributed with a mean of 6.02 6.02 centimeters and a standard deviation of 0.05 0.05 centimeters. Find the two lengths that separate the top 9% 9% and the bottom 9% 9% . These lengths could serve as limits used to identify which nails should be rejected. Round your answer to the nearest hundredth, if necessary.

Answers

Step-by-step explanation:

First, use a z-score table or calculator to find the z-score that corresponds to the percentile.  Using a calculator, z = -1.3408 is the bottom 9%, and z = 1.3408 is the top 9%.

Now calculate the length that corresponds to these z scores.

z = (x − μ) / σ

-1.3408 = (x − 6.02) / 0.05

x = 5.95

1.3408 = (x − 6.02) / 0.05

x = 6.09

So the bottom 9% and the top 9% are between 5.95 cm and 6.09 cm.

Final answer:

To separate the top and bottom 9% of nail lengths, we can use the z-score formula. The top 9% length is approximately 6.088 cm and the bottom 9% length is approximately 5.952 cm.

Explanation:

To find the lengths that separate the top and bottom 9%, we can use the z-score formula. The z-score is calculated by subtracting the mean from the data value and dividing it by the standard deviation. For the top 9%, we need to find the z-score that corresponds to an area of 0.91. Now calculate the length that corresponds to these z scores.

z = (x − μ) / σ

-1.3408 = (x − 6.02) / 0.05

x = 5.95

1.3408 = (x − 6.02) / 0.05

x = 6.09

So the bottom 9% and the top 9% are between 5.95 cm and 6.09 cm.

We are going to do the operations in the grouping symbol.

A grouping symbol is anything that operations grouped together in it like that first square root.

[tex]\sqrt{25}-(\sqrt{16}+\sqrt{9})[/tex]

We can also perform the operation inside the other grouping symbols ().

But it has addition and square roots. The square roots come first then the addition.

Now the square roots can be kind of though as exponents and actually you could think of something like [tex]\sqrt{9}[/tex] as [tex]9^{\frac{1}{2}}[/tex].

16 and 9 must be added as they are under the same root. We get 25 which is a perfect square. Next, 16 and 9 in parentheses are under different roots so they can’t be added. So, get the square root from 16 and 9 separately. This way we get 5-(4+3). Now, combine 5-(7). Next, multiply by - sign. This gives us a negative number. So, we get 5-7. Which equals -2.

for a baseball team the ratio of wins and ties and losses is 4:3:1 if the team has won 12 games how many games have they lost ​

Answers

Answer: 3 losses

Step-by-step explanation: The win to loss ratio is 4:1. Their losses are 1/4 of their wins. Multiply 12, their number of wins, by 1/4.

12 x 1/4 = 3

They have lost 3 games.

Final answer:

Given the ratio of 4:3:1 for wins, ties, and losses, and the information that the team has won 12 games, you calculate that '1 part' of the ratio equals 3 games by dividing 12 by 4. As losses are represented by '1 part' in the ratio, the team has lost 3 games.

Explanation:

In this baseball team scenario, the ratio of wins to ties to losses is 4:3:1 respectively. You know that the team has won 12 games. In a ratio, every part represents something equivalent, so we need to find what '1 part' is. Since '4 parts' represents 12 wins, you divide 12 by 4 to get '1 part', which is 3 games. Therefore, since losses represent '1 part' of your ratio, the team has lost 3 games.

A coffee distributor needs to mix a(n) Organic Free Trade coffee blend that normally sells for $8.30 per pound with a Rift Valley coffee blend that normally sells for $13.90 per pound to create 80 pounds of a coffee that can sell for $10.82 per pound. How many pounds of each kind of coffee should they mix?

Answer: They must mix
_____ pounds of the Organic Free Trade Blend
______ pounds of the Rift Valley Blend.
Round your answers to the nearest whole number of pounds.

Answers

Answer:

They must mix

_44_ pounds of the Organic Free Trade Blend

_36__ pounds of the Rift Valley Blend.

Round your answers to the nearest whole number of pounds.

Step-by-step explanation:

The formula you are using is:

Total price * total amount= Organic price * amount organic + Rift price * amount rift

First we will simplify it by calculating it for each pound of final mix.

So this is 10.82 * 1 = 8.30 * x + 13.90 * y.

Since the total amount should be 1 pound, you could say that x+y = 1, or that y = 1-x.

If you fill this in you get

10.82 * 1 = 8.30 * x + 13.90 * (1-x)

Which you can solve as follows.

10.82 * 1 = 8.30 * x + 13.90 - 13.90x

10.82 = 13.90 - 5.6x

-5.6x = -3.08

x = -3.08/-5.6 = 0.55

So you will need 0.55 of Organic coffee for each pound of the final mix.

So in total you will need 0.55 * 80 = 44 pounds of Organic coffee.

So you need 80 - 44 = 36 pounds of Rift Valley Coffee.

Final answer:

To produce the desired coffee blend, the coffee distributor needs to mix approximately 51 pounds of Organic Free Trade Blend with 29 pounds of Rift Valley Blend.

Explanation:

This problem falls under a category of Mathematics known as Algebra. We'll start by defining two variables: x, representing the weight of the Organic Free Trade Blend, and y, representing the weight of the Rift Valley Blend.

From the total weight of the mix, we get our first equation: x + y = 80

Then, by weighing the cost of each part against the total, we get our second equation: 8.3x + 13.9y = 10.82 * 80.

Solving these two equations simultaneously, we find that approximately 51 pounds of Organic Free Trade and 29 pounds of Rift Valley blend are needed to create the desired mixture.

Answers

Answer:

(6,∞)

x > 6

Step-by-step explanation:

Solve by adding 4 to both sides.

[tex]x-4>2\\x>6[/tex]

To put this in interval notation for your solution set, consider your sign.

You have a greater than sign, which means that 6 is not a solution. In interval notation, that means that you should use parentheses " ( " instead of brackets " [ ".

Your solution set goes on infinitely, and infinity also uses parentheses rather than brackets.

You can write your solution set in interval notation as follows:

(6, ∞)

A population of 1,000 bacteria is treated with a medicine and begins to die 5% each hour. How can the bacteria population be determined after a number of hours, ℎ?

a. (ℎ)=0.95(ℎ+1,000)

b. (ℎ)=1,000·ℎ^0.95

c. (ℎ)=0.95ℎ+1,000

d. (ℎ)=1,000·0.95^ℎ

Answers

Answer:

[tex]1000(.95)^h[/tex]

Step-by-step explanation:

[tex]h(t)=A \cdot B^t[/tex] is an exponential equation where A is the beginning amount and B is the rate that the population grows or dies.

So we start with 1000 bacteria, they are giving us A.

The bacteria population is decreasing because they are dying 5% each hour.

So that is after the first hour we have 1000-.05(1000) or 1000(1)-1000(.05)=1000(1-.05)=1000(.95).

We will keep multiplying by .95 per hour. 0.95 is the repeated factor.

That is the function is [tex]1000(.95)^h[/tex].

If you let h=0 which means 0 hours has happened, you will see the bacteria is 1000 as desired. 1000(.95)^0=1000(1)=1000.

Final answer:

The bacteria population can be determined using the formula (ℎ)=1,000·0.95^ℎ, which represents exponential decay at a rate of 5% each hour. therefore, option D is correct

Explanation:

To determine the bacteria population after a number of hours, we need to use the formula (ℎ)=1,000·0.95^ℎ. This formula represents the exponential decay of the bacteria population at a rate of 5% per hour. The initial population is 1,000, and each hour the population decreases by 5% (or 0.95).

For example, after 1 hour, the population can be calculated as (1,000)·(0.95)^1 = 950 bacteria. After 2 hours, the population would be (1,000)·(0.95)^2 = 902.5 bacteria, and so on.

Therefore, the correct answer is (d) (ℎ)=1,000·0.95^ℎ.

How do you do 6 divided by 11 bus stop method, please explain the steps?

Answers

I had to google what the bus stop method was so I apologize if this is wrong.

First, you think about if 11 can go into 6. Since it can’t you move on another digit by adding a decimal after the six and a 0 after the decimal. Also remember to play a decimal above the place where the decimal is in the box. Next, you think about if 11 can go into 60, it can go in 5 times. So the answer is approximately .5. I will attach a picture if it helps.

what will be the circumference of a circle if the area is 64cm

Answers

Given that area of circle is 64cm we can assume we will need to first find radius and then calculate circumference.

First we know that area of a circle is [tex]A=\pi r^2[/tex] hence [tex]r=\sqrt{\dfrac{A}{\pi}}[/tex]

We can now put in our area,

[tex]r=\sqrt{\dfrac{64}{\pi}}\approx20.37[/tex]

Then we use the formula for circumference,

[tex]C=2\pi r\Longrightarrow C=2\pi\cdot20.37\approx\boxed{128\mathbf{cm}}[/tex]

Hope this helps.
