= 9/14 <----- simplify

Answer:

y=3x+12

y-12=3x

x=y/3 - 4

f(y)=y/3 - 4

or

f(x)=x/3 - 4

where f(x) is the inverse of y.

Step-by-step explanation:

David spent 60% of his money which was in his wallet.

Applying Euler's method:

Let f(x, y) = 2x - 3y + 1, and consider the following recurrence relations:

[tex]\begin{cases}x_0=1\\x_n=x_{n-1}+h&\text{for }n\ge1\end{cases}[/tex]

[tex]\begin{cases}y_0=5\\y_n=y_{n-1}+f(x_n,y_n)h&\text{for }n\ge1\end{cases}[/tex]

For step size h = 0.1, we can approximate y (1.2) with just 2 steps:

[tex]\begin{cases}x_0=1\\y_0=5\end{cases}\implies y_1=5+f(1,5)\times0.1=3.8[/tex]

[tex]\begin{cases}x_1=1+0.1=1.1\\y_1=3.8\end{cases}\implies y_2=3.8+f(1.1,3.8)\times0.1=\boxed{2.98}[/tex]

For step size h = 0.05, we need 4 steps:

[tex]\begin{cases}x_0=1\\y_0=5\end{cases}\implies y_1=5+f(1,5)\times0.05=4.4[/tex]

[tex]\begin{cases}x_1=1+0.05=1.05\\y_1=4.4\end{cases}\implies y_2=4.4+f(1.05,4.4)\times0.05=3.895[/tex]

[tex]\begin{cases}x_2=1.05+0.05=1.1\\y_2=3.895\end{cases}\implies y_3=3.895+f(1.1,3.895)\times0.05=3.47075[/tex]

[tex]\begin{cases}x_3=1.1+0.05=1.15\\y_3=3.47075\end{cases}\implies y_4=3.47075+f(1.15,3.47075)\times0.05\approx\boxed{3.1151375}[/tex]

(Compare these to the value of y (1.2) found using the exact solution to the differential equation, about 3.22832.)

Answer:

m<B: 56

Step-by-step explanation:

All triangles add up to 180

<B = x

x + 34 + 90 = 180

x + 124 = 180

x = 56

Over the first 40 s, the object had an acceleration a such that

90 m/s = a (40 s)   →   a = (90 m/s) / (40 s) = 2.25 m/s²

[tex]b-2[/tex]

Step-by-step explanation:

[tex](3b+4) + (-2b-6)[/tex]

We will need to add like terms. 3b and -2b are like terms and 4 and -6 are like terms.

Let's add 3b and -2b.

[tex]b+4-6[/tex]

We can now add the like terms 4 and -6.

Answer:

-A clothing store claims that 45% of its customers prefer skinny jeans over regular jeans. They concluded this from a survey which asked 120 randomly selected teenage customers which style they prefer.

-A report by a company that manufactures hair brushes says 56% of people who buy their brushes own only one hair brush. The conclusion comes from a survey of 500 males who bought the company's brush.

The scenarios in which the statistics are misleading; option 1 and 3.

A portion of population taken and analyzed to predict information about population is called sample of that population.

Ex: When someone surveys a group, then he/she surveys a portion and not whole population in general.

Those numbers who summarize information about sample are called statistic.

(Statistic is different than statistics)

The  numbers which summarize information about the sample are called statistic.

The scenarios in which the statistics are misleading;

1) A clothing store claims that 45% of its customers prefer skinny jeans over regular jeans. They concluded this from a survey which asked 120 randomly selected teenage customers which style they prefer.

Answer:

x = 18 y = 10

Step-by-step explanation:

let the first number be x

let the second number be y

x = y + 8..... equation 1

2x + y = 46.... equation 2

x is the larger number

y is the smaller number.

Rearrange the equation and add equation 1 to equation 2.

x - y = 8

+ 2x + y = 46

-------------------

3x + 0 = 54

3x = 54

divide both sides by 3

x = 54/3

x = 18

Substitute x = 18 into equation 1

x = y + 8

18 = y + 8

collect like terms

y = 18-8

y = 10

The two numbers are 18 and 10

From the question, One number is 8 more than another

Let the first number be x and the second number be y

∴ x = y + 8 ------ (1)

From the second statement, the sum of the smaller number and twice the larger number is 46

That is,

y + 2x = 46 ----- (2)

Now, we will solve the two equations simultaneously

From equation (1)

We have x = y + 8

Substitute this into equation (2)

y + 2x = 46

y + 2(y+8) = 46

Then, clear the bracket

y + 2y + 16 = 46

3y + 16 = 46

Collect like terms

3y = 46 - 16

3y = 30

∴ y = 30 ÷ 3

y = 10

Substitute the value of y into equation (1)

x = y + 8

x = 10 + 8

x = 18

∴ x = 18 and y = 10

Hence, the two numbers are 18 and 10

Answer: R204.06

Step-by-step explanation:

Cost of clock = R179

Value Added Tax = 14%

The price of the clock will be the addition of the cost of the clock and the value added tax. This will be:

= R179 + (14% × R179)

= R179 + (0.14 × R179)

= R179 + R25.06

= R204.06

Therefore, the price of the clock is R204.06.

Tallahassee's Range: 6

Key West's Range: 4

Step-by-step explanation:

To calculate range, you'd subtract the lowest value from the highest value

Tallahassee:

Highest Value: 90

Lowest Value: 84

Range: 90 - 84 = 6

Key West:

Highest Value: 87

Lowest Value: 83

Range: 87 - 83 = 4

Answer:

4,99%

Step-by-step explanation:

By Themba you write 28/100 because a percentage means 100 ,you 100 by 28 and then your common fraction answer will be 7/25 in a decimal way it is 0,28 .

Jamal is 0,3 which is 0,3 means 3/10 and Alison 1/8 and the answer for Alison is 0,125 or in a common fraction way it is 125/10.

And then you add all the answers and you get 141/200 .

And then 500-7/25-3/10-0,125 and then you get 499,295, and 499,295÷100 =4,99 which is 4,99%.

I hope this works.

Answer:

9/4

Step-by-step explanation:

0.25 is one fourth and if you convert the whole number into fourths and add the one fourth from the decimal it is 9/4

Answer:

9/4

Step-by-step explanation:

First ever need to make this decimal a fraction.

Convert decimal to fraction

2.25 = 225/100

Now we need to simplify.

225/25=9

100/25=4

9/4 or 2 1/4

Answer:

20%

Step-by-step explanation:

Skills needed: Percents, Subtraction with Percents

1) When looking at Shira's graph, we know that:

2) We need to find the percent amount she uses for bills. Now, the circle graph represents One-Whole, or in other words: 100% total

This graphs shows all of her expenses, 100% of it

3) So based on this, we can easily solve for the Bills. Let's make the bills a variable [tex]b[/tex]

A variable is a letter or symbol used to show a specific value we are usually trying to find in a problem.

4) So, we can make an equation:

--> 30% + 30% + 15% + [tex]b[/tex]% = 100%

35% + 30% + 15% = 80%

So based on the step above: 80% + [tex]b[/tex]% = 100%

Subtract 80% from both sides, and you will get: [tex]b[/tex]% = 100% - 80%

100% - 80% = 20%

So then [tex]b[/tex]% = 20%

Therefore 20% is your answer

Important note: Subtracting with percentages is very similar to subtract with regular numbers, except they contain a percent-sign (%) after the numbers.
