What’s negative 5 + 1 fourth equal

Answer:

Julie can run 12 laps

Step-by-step explanation:

9 min = 3 laps

9 x 2 = 18 = 6 laps

9 cant fit into 24 again

24 - 18 = 6

6 + 6 = 12 laps

The base area of the prism is 2x² + 5x - 18

From the question, the given parameters are

Volume = 2 x cubed + 9 x squared minus 8 x minus 36

Height =  x + 2

Rewrite properly as

Volume = 2x³ + 9x² - 8x - 36

Height =  x + 2

The base area is calculated as

Base area = Volume/Height

Using the synthetic division, we have

Set the divisor to 0

x + 2 = 0

This gives

x = -2

So, we have the representation to be

-2 | 2   9  - 8  - 36

Write out 2

So, we have

-2 | 2   9  - 8  - 36

     2

Multiply 2 and -2

This gives

-2 | 2   9  - 8  - 36

          -4

     2

So, we have

-2 | 2   9  - 8  - 36

          -4

     2    5

Repeat the process

So, we have

-2 | 2   9  - 8  - 36

          -4  -10

     2    5   -18

Repeat the process

So, we have

-2 | 2   9  - 8  - 36

          -4  -10   36

     2    5   -18    0

This means that

Base area = 2x² + 5x - 18

Given:

The total amount is P = $10,000.

The rate of interest is r(1) = 10% 0.10.

The other rate of interest is r(2) = 8%=0.08.

The number of years for both accounts is n = 1 year.

The total interest earned is A = $820.

The objective is to find the amount invested in each account.

Explanation:

Consider the amount invested for r(1) as P(1), and the interest earned as A(1).

The equation for the amount obtained for r(1) can be calculated as,

Consider the amount invested for r(2) as P(2), and the interest earned as A(2).

The equation for the amount obtained for r(2) can be calculated as,

Since, it is given that the total interest earned is A=$820. Then, it can be represented as,

On plugging the obtained values in equation (3),

Also, it is given that the total amount is P = $10,000. Then, it can be represented as,

Substitute the equation (3) in equation (4).

To solve this, we will need to convert all values to decimal.

First convert 1/4 to decimal:

Now convert 43% to decimal:

Simplify 5/9:

0.15 is already a decimal value.

Simplify 1/12:

1.4 is already a decimal.

After simplifying, we have the following values:

0.25

0.43

0.56

0.15

0.083

1.4

We can see the values greater than 0.25 are:

0

First, we are going to divide the figure and named new points X and Y as:

Now, we know that TS is the sum of TX and XS.

TS = TX + XS

Adittionally, TX has the same length of HJ, so:

TX = HJ = 14

Now, we want to know the length of YK, and we can calculate it using the following equation:

LK = LY + YK LY is also equal to HJ, so LY = 14

42 = 14 + YK

42 - 14 = YK

28 = YK

Finally, since T and S are midpoints, the length of XS is the half of the length of YK. It means that XS is:

XS = YK/2

XS = 28/2

XS = 14

Therefore, TS is equal to:

TS = TX + XS

TS = 14 + 14

TS = 28

Answer: TS = 28

You have the following fraction:

180000/120000

First of all you cancel zeros:

180000/120000 = 18/12

next, you can simplify

18/12 = 9/6 = 3/2

finally 3/2 is:

3/2 = 1.5

Hence: 180000/120000 = 1.5

Furthermore, for the following fraction:

0.11/0.08

First, we need to identify the square root of the fisrt squared numbers:

Since 40 is a number between 36 and 49, we can say that the square root of 40 is between 6 and 7. So:

The equation of a line in the slope intercept form is expressed as

y = mx + c

where

m = slope

c = y intercept

The formula for calculating slope is expressed as

m = (y2 - y1)/(x2 - x1)

where

x1 and y1 are the x and y coordinates of the initial point

x2 and y2 are the x and y coordinates of the final point

From the information given, the initial point is (- 2, - 4) and final point is (2, 8)

Thus,

x1 = - 2, y1 = - 4

x2 = 2, y2 = 8

By substituting these values into the slope formula,

m = (8 - - 4)/(2 - - 2) = (8 + 4)/(2 + 2) = 12/4 = 3

We would find the y intercept, c by substituting m = 3, x = - 2 and y = - 4 into the slope intercept equation. We have

- 4 = 3 * - 2 + c

- 4 = - 6 + c

Adding 6 to both sides of the equation,

- 4 + 6 = - 6 + 6 + c

c = 2

By substituting m = 3 and c = 2 into the slope intercept equation, the equation of the line is

C) y = 3x + 2

Let x be a random variable representing the blood pressures of adults in the USA. Since it is normally distributed, we would apply the formula for determining z score which is expressed as

z = (mean - population mean)/standard deviation

From the information given,

population mean = 121

Standard deviation = 16

For stage 2 high blood pressure, the probability is

P(x greater than or equal to 160). It is also equal to 1 - P(x < 160)

Thus, for x = 160, we have

z = (160 - 121)/16 = 2.4375

From the standard normal distribution table, the probability value corresponding to a z score of 2.4375 is 0.9927

P(x < 160) = 0.9927

P(x greater than or equal to 160) = 1 - 0.9927 = 0.0073

Converting to percentage, it is 0.0073 * 100 = 0.73%

b) If 2000 peaople were sampled, the number of people with stage 2 high blood pressure would be

0.73/100 * 2000 14.6

To the nearest person, it is 15 people

c) For stage 1, the probability is

P(140 < x < 160)

For x = 140,

z = (140 - 121)/16 = 1.1875

From the standard normal distribution table, the probability value corresponding to a z score of 1.1875 is 0.883

Recall, for x = 160, the probaility is 0.9927

Thus,

P(140 < x < 160) = 0.9927 - 0.883 = 0.1097

Converting to percentage, it is

0.1097 * 100 = 10.97%

d) The 30th percentile refers to all values of blood pressure below k, where k is the 30th percentile. This means that we would find

P(x < k) = 0.3

The z score corresponding to a probability value of 0.3 is - 0.52

Thus,

(k - 121)/16 = - 0.52

k - 121 = - 0.52 * 16 = - 8.32

k = - 8.32 + 121

k = 112.68

The pressure for the 30th percentile is 112.68

Distributive property

In this property, multiplying the sum of two or more terms in that add up in a bracket by a number outside the bracket will be equal to multiplying each term in the bracket individually and then followed by sum of the product. In this question:

In a linear relationship, each step of x modifies the y value in the same way.

In the first table, when x = 1, y = 3 and when x = 2, y = 6. This is an increment of 3. If this is a linear relationship, we expect the next value of y to be the previous value plus 3, thus y = 9. But in the table shows x =3 and y = 12. We can rule out the first table.

With similar reasoning, in the second table, we see (1, 2) and (2, 5). This is an increase of the y value of 3. We expect the next value to be y = 8, but we see (3, 9). The second table is not a linear relationship.

In the third table, we see (1, -3) and (2, -5). This is a decrease of -2. We expect the next value of y to be y = -7, and we do see (3, -7). The next value should be y = -9, and the table shows (4, -9). Table 3 shows a linear relationship.

To be sure, let's see the 4th table. We see (1, -2) and (2, -4). This is a decrease of -2. The expected next value is y = -6, but the next point is (3, -2). Fourth table is not a linear relationship.

Thus, the correct answer is the top-right table.
