after months of negotiations,jabus annual salary was increased by 6,5percent to R330 000. determine his previous monthly salary and the monthly increase he will be getting​

Answers

Answer:

previous monthly salary is R 308,550 and increment is R 21,450

Step-by-step explanation:

Let the previous monthly salary be x

Current salary = R 330,000

Percent increase = 6,5%

Increase = 6.5% * 330,000

Increase = 0.065 * 330,000

Increase = Rs21,450

Previous salary = 330,000 - 21,450

Previous salary = 308,550

Hence previous monthly salary is R 308,550 and increment is R 21,450

Find the value of x for ABCD is a parallelogram

Answers

Find parallelogram ABCD attached

Answer:

x = 3

Step-by-step explanation:

In parallelograms, the diagonals typically divide each other into 2 equal parts.

This means that from the attached parallelogram, we can say that;

4x - 6 = 2x or 6x - 15 = x

Thus;

4x - 2x = 6

2x = 6

x = 6/2

x = 3

Let's confirm with the second equation;

6x - x = 15

5x = 15

x = 15/5

x = 3

Answers

Answer:

35

Step-by-step explanation:

[tex]\frac{9}{y} =\frac{36}{100}[/tex]

y × 36 = 9 × 100

36y = 900

36y ÷ 36 = 900 ÷ 36

y = 35

Answer:

25

Step-by-step explanation:

36%     9        

--------------       (36% over 100% and 9 over x)

100%    x

Cross multiply: 36% times x and 100% times 9

36% times x=36x

100% times 9=900

Divide: 900 divided by 36=25

25 is your answer

Cos(x+y)cos(x-y)=cos^2y - sin^2x

Answers

cos(x + y) cos(x - y) = (cos(x) cos(y) - sin(x) sin(y)) (cos(x) cos(y) + sin(x) sin(y))

… = (cos(x) cos(y))² - sin(x) sin(y) cos(x) cos(y) + sin(x) sin(y) cos(x) cos(y) - (sin(x) sin(y))²

… = (cos(x) cos(y)) - (sin(x) sin(y))²

… = cos²(x) cos²(y) - sin²(x) sin²(y)

… = (1 - sin²(x)) cos²(y) - sin²(x) sin²(y)

… = cos²(y) - sin²(x) cos²(y) - sin²(x) sin²(y)

… = cos²(y) - sin²(x) (cos²(y) + sin²(y))

Four fewer than triple the sum of x and 3 is 17

Answers

Answer:

4- 3(x -3) =17 x =10

Step-by-step explanation:

We are going to start with the sum of x and 3. You can write that like this : x+3. Then, it says “triple the sum of x and 3”. That would be 3(x+3). Then it says “four fewer”. So that is 3(x+3)-4. And all of that equals to 17. So the equation is 3(x+3)-4=17.
Then to solve that, we are going to add 4 to both sides. So now our equation looks like 3(x+3)=21. Then divide by 3 on both sides. (x+3)=7. Subtract 3 on both sides. x=4.

d. the value of the parameter of interest cannot be determined from the given information.

Answers

Answer:

The value of the parameter of interest in this setting is 0.5747.

Step-by-step explanation:

The parameter of interest is:

The proportion of small- to medium-sized streams in eastern North Carolina which have runoff from hog farms in order to prepare for issues arising from water quality in the aftermath of hurricanes.

A random sample of 174 small- to medium-sized streams is selected and it is found that 100 of them have runoff from hog farms.

This means that the value of the parameter of interest is:

[tex]p = \frac{100}{174} = 0.5747[/tex]

The value of the parameter of interest in this setting is 0.5747.
