Explain how to solve rate of wind and rate of current problems

Answers

Answer 1

Final answer:

To solve rate of wind and current problems, analyze the given velocities, represent them as vectors, perform vector addition, and apply trigonometry to find the effective velocity or required direction. This method helps in determining the true path of a vehicle influenced by wind or current.

Explanation:

To solve rate of wind and rate of current problems, it is essential to understand vectors and relative motion. Here is a step-by-step approach to solving these problems:

Analyze the question to understand what is being asked, including the direction and magnitude of both the wind/current and the vehicle (aircraft, boat, etc.).Represent the given velocities as vectors. The wind or current velocity should be added to the vehicle’s velocity to determine the resulting path.Apply the vector addition concept to calculate the effective velocity of the vehicle relative to the Earth. This might include using trigonometric functions to resolve vectors into components.Once the effective velocity is known, use it to solve for other quantities like travel time, distance, or the required heading to reach a certain destination.

For example, if an aircraft flies with a wind velocity of 200 km/hr blowing from the south and its relative velocity with respect to wind is 1000 km/hr, the direction in which the aircraft should fly to reach a north-eastern destination can be calculated using vector addition and trigonometry.

How many 2/3 -cup servings are in four cups of pistachios?

Answers

Answer:

4 Of them

Step-by-step explanation:

So an easy way to do this is by adding 2/3 for a while till we hit max. Like this:

2/3+2/3=1 1/3+2/3= 2+2/3=2 2/3+ 2/3= 3 1/3+2/3= 4. so 6 of them

Hope this helps!

Final answer:

To find out how many 2/3-cup servings are in four cups of pistachios, you divide 4 cups by 2/3 cup, which equals 6 servings.

Explanation:

To determine how many 2/3-cup servings are in four cups of pistachios, you would divide the total number of cups by the size of one serving:

Total servings = Total volume \/ Size of one serving = 4 cups / (2/3 cup)

To divide by a fraction, multiply by its reciprocal:

Total servings = 4 / (2/3) = 4 * (3/2) = 4 * 1.5 = 6

So, there are six 2/3-cup servings in four cups of pistachios.

--- Strep throat is caused by Streptococcus bacteria. The amount of bacteria multiplies at a rate of 10^13 per 10^2 hrs. What is the average growth of bacteria per hour?

Answers

The equation is pretty straightforward. Basically, if 10^13 bacteria multiplies in 100 hours. We seek to know how many bacteria multiply per hour. So if 10^13 bacteria mulitply in 100 hours Then X bacteria multiply in an hour. Hence X bacteria * 100 hours = 10 ^13 bacteria * 1 hour. X = 10 ^13 * 1 / 100= 10^(13-2) 10^11. Basically, 10^11 bacterias multiply in an hour.

The average growth of the bacteria per hour is [tex]10^{11}[/tex].

To find the average growth of bacteria per hour, we need to determine the rate at which the bacteria multiply per hour.

Given:

The amount of bacteria multiplies at a rate of [tex]\(10^{13}\)[/tex] per [tex]\(10^2\)[/tex] hour.

We want to find the growth rate per hour.

First, let's find out how much the bacteria multiplies per hour:

If the bacteria multiply by  [tex]\(10^{13}\)[/tex] in [tex]\(10^2\)[/tex] hours, then the average growth per hour can be found by dividing the total growth in [tex]10^{13[/tex] hours by [tex]10^2[/tex].

So, the growth per hour is:

Growth per hour} = [tex]\frac{10^{13}}{10^2}[/tex]

Growth per hour} = [tex]10^{13 - 2}[/tex]

Growth per hour} = [tex]10^{11}[/tex]

Therefore, the average growth of bacteria per hour is [tex]10^{11}[/tex].

Find the next three numbers in the pattern: 1, 4, 9, 16, 25, 36, ...

Answers

Judging by the way the pattern goes,
1+3=4
4+5=9
9+7=16
16+9=25
25+11=36

Then the next 3 numbers would be: 
36+13= 49
49+15=64
64+17=81

The next three numbers are 49, 64 and 81

The pattern is adding 2 to each number. So 3 is added to 1 to make 4. The next number added to 4 would be 5, so on so forth. 

Answer: 49, 64, and 81

Step-by-step explanation: To find the next three terms in this pattern, begin by studying the pattern.

Notice that the difference between 1 and 4 is positive 3, the difference between 4 and 9 is positive 5, the difference between 9 and 16 is positive 7, the difference between 16 and 25 is positive 9, and the difference between 25 and 36 is positive 11.

Since the differences are increasing by 2 each time, we can find the next term in the pattern by adding 36 + 13 to get 49. Next, we will add 49 + 15 to get 64. Then, we will add 64 + 17 to get 81.

Thus, the next three terms in the pattern are 49, 64, and 81.

What is m∠PTS? ??????????????

Answers

∠PTS is equal to ∠RTQ because of the Theorem of Vertical Angles.

Using substitution we get 11(y - 10) = 4y - 5

Solve for x.

11(y - 10) = 4y - 5
11y - 110 = 4y - 5 <-- Distribute the 11
7y - 110 = -5 <-- Subtract 4y from each side
7y = 105 <-- Add 110 to each side
y = 15 <-- Divide both sides by 7

Now that we have the value of y, substitute it back into the equation.

11(15 - 10) = 11 * 5 = 55

So, the answer is 55 degrees.

the product of two consecutive even integers is 48 find the integers

Answers

To start, define your variables, x will be the first even integer, and x+2 will be the greater of the two even integers (you would add 2 since even integers are 2 numbers apart). Then, since the product of the two integers is 48, you would set up an equation that looks like this: x(x+2)=48.
Once you simplify, you should get an equation that looks like a quadratic: 
x^2+2x=48. Now, to find the values of x, you have to solve for the roots or zeroes, which means you will have to set the equation to 0. To do this, subtract 48 from both sides and you get: x^2+2x-48=0.
Then, factor the equation and you get: (x+8)(x-6)=0
Now, to solve for x, set each factor to 0, which would look like this:
x+8=0
x-6=0
Now, solve each one for x and you get x=-8 and x=6
Then, to find the pairs for each integer, add 2 to each x and you get that the two sets of integers that equal 48 as their product are -8 and -6; and 6 and 8


The required integers are -8 and -6, or 6 and 8 whose the product of two consecutive even integers is 48

What are Integers?

Integers are defined as the collection of Whole Numbers and the negative values of Natural Numbers make up an integer.

Let the two consecutive even integers be 2n and 2(n+1), where n = any integer.

As per the given condition, The product of the two integers is 48

2n × 2(n+1) = 48            

Multiply out, and subtract 48 from both sides

4n2+4n-48=0                            

Divide both sides by 4

n²+n-12=0                            

Factor the quadratic

(n+4)(n-3)=0                      

n= -4 and +3

For n= -4, 2n = -8 and 2(n+1) = -6.  (-8)(-6) = 48

For n=3, 2n = 6 and 2(n+1) = 8.  (8)(6) = 48

Thus, the required integers are -8 and -6, or 6 and 8.

I need help on 22-27

Answers

22-27 would be 5 because ya so hahahhahahahhahaha
Oh, this is really simple m8
Alright, for 22: It doesn't matter how many 0's you add after the main digits (there's an official term for these digits, but I don't exactly recall it at this moment)
BASICALLY, 0's are just being used as placeholders AFTER  the main digits, which in this case is 2.6
So, you can say 2.6, 2.60, 2.600, 2.6000, 2.60000000, but those 0's are meaningless really, because they all REALLY have the same value, 2.6. Your choice that they want is 2.06. You can't toss a 0 between the main digits without changing the value. 
So, 22=2.06

Using the same methods as I said, notice how the main digits in 23 are 4.07. This is unchanging. Anything that gets tossed in between changes the numbers value. The answer they want is 4.70. 

Using the same methods as above, notice how the main digits in 24 are 65.8. The answer they want, the choice that's different, is 65.08

Same thing for 25. The main digits are 37.06, so the choice they are looking for, the only one with a different value, is 37.6

For 26, three decimals that are equivalent: 
For example: .5, .50, .500 are all equal. 

For 27, rewrite these as fractions. That's easy.
In algebra, there are names for anything after the decimal. The first number that comes after the decimal is known as the "tenth", the second is known as the "hundredth", the third is known as the "thousandth", so on. 

Applying that, we can convert these into fractions, using each decimals respective value as the denominator here.

.5 is in the tenth place, so as a fraction it's 5/10
.50 is in the hundredth place total, so as a fraction it's 50/100
.500 is in the thousandths place total (meaning this is where it ends), so it's 500/1000 as a fraction. 
But in the end, ALL of these are the same value, 5/10

add a thanks...

Final answer:

Deepak must work 4 or fewer hours to earn at least $90 per job.

Explanation:

The question is asking about the inequality that Deepak, a landscaper, writes to determine the number of hours he must work during each job in order to earn at least $90 the job. We can break down the equation as follows:

Let x be the number of hours Deepak works.

The equation can be written as: $30 + $15x ≤ $90.

To solve for x, we subtract $30 from both sides: $15x ≤ $60.

Then, we divide both sides by $15: x ≤ 4.

Therefore, Deepak must work 4 or fewer hours to earn at least $90 per job.

Nora had already read thirty percent of the book before he teacher assigned it to the class she is choosing between two options.option1:read 25%of the remaining pages each night or option2:read 28pages each night

Answers

Choosing option 1 will take 3 nights.

Nora should choose Option 1 because it will take her 4 nights to finish instead of 25 nights with Option 2.

Let's break down Nora's situation step by step:

1. Calculate the total number of pages in the book:

  Since Nora has already read thirty percent of the book, we can find the total number of pages by dividing the portion she read by 30% (or 0.30). Let's denote the total number of pages as ( P ).

[tex]\[ P = \frac{{\text{portion Nora read}}}{{\text{percentage read}}} = \frac{{\text{portion Nora read}}}{{0.30}} \][/tex]

2. Calculate the portion of the book Nora has already read:

  If Nora has already read thirty percent of the book, then she has already read [tex]\( 0.30 \times P \)[/tex] pages.

3. Calculate the number of pages Nora has remaining:

  Subtract the pages Nora has already read from the total number of pages in the book.

[tex]\[ \text{Pages remaining} = P - (0.30 \times P) = P(1 - 0.30) = 0.70P \][/tex]

4. Option 1: Read 25% of the remaining pages each night:

  Nora's plan is to read 25% of the remaining pages each night. Since she has (0.70P) pages remaining, she will read [tex]\( 0.25 \times 0.70P \)[/tex] pages each night.

5. Option 2: Read 28 pages each night:

  Nora's other option is to read 28 pages each night.

6. Compare the two options:

  To determine which option Nora should choose, we compare the number of nights it will take her to finish each option.

  - With Option 1, the number of nights Nora will need to finish the book is [tex]\( \frac{{0.70P}}{{0.25 \times 0.70P}} \).[/tex]

  - With Option 2, the number of nights Nora will need to finish the book is [tex]\( \frac{{0.70P}}{{28}} \).[/tex]

7. Choose the more efficient option:

  Nora should choose the option that requires fewer nights to finish the book.

Let's summarize the steps:

1. Calculate the total number of pages in the book.

2. Determine the portion of the book Nora has already read.

3. Calculate the number of pages Nora has remaining.

4. Calculate the number of pages Nora will read each night for Option 1.

5. Compare the number of nights needed for each option.

6. Choose the option that requires fewer nights to finish the book.

This process will help Nora decide which option is more efficient for her to finish reading the book.

Let's denote:

- Total number of pages in the book as ( P ).

- Number of pages Nora has already read as ( 0.30P ).

- Number of pages Nora has remaining as ( 0.70P ).

With Option 1, Nora will read [tex]\( 0.25 \times 0.70P = 0.175P \)[/tex] pages each night.

To find the number of nights needed to finish with Option 1:

[tex]\[ \text{Number of nights with Option 1} = \frac{{0.70P}}{{0.175P}} = 4 \][/tex]

With Option 2, Nora will read 28 pages each night.

To find the number of nights needed to finish with Option 2:

[tex]\[ \text{Number of nights with Option 2} = \frac{{0.70P}}{{28}} = 25 \][/tex]

Nora should choose Option 1 because it will take her 4 nights to finish instead of 25 nights with Option 2.
