if cot a =5/12 then find the value of cosec A​

Answers

Answer:

cosec A = 13/12

Step-by-step explanation:

Mathematically, we want to find the value of cosec A

sides 5,12 and 13 represent a Pythagorean triple. This means the last side of the right-triangle that contains 5 and 12 is 13

cot is the ratio of the adjacent to the opposite

Hence ; 5 represents the adjacent while 12 represents the opposite

cosec is the inverse of sine which is the hypotenuse to the opposite ratio

So, we have ;

cosec A = 13/12

A box of chocolates contains milk chocolates and dark chocolates in the ratio 4:3
The box contains 35 chocolates
how many milk chocolates are there in the box?

Answers

Answer:

20 milk chocolates

Step-by-step explanation:

The first step is adding together 4 + 3. You will get 7. This is the total number of units in the box.

Then, divide 35 by 7. You will get 5 as the answer.

To find the number of milk chocolates, multiply 5 and 4. You will get 20 as the answer.

4x+3x=35
7x=35
x=5

milk chocolate 4(5) = 20
dark chocolate 3(5) = 15

What is the result when the number 27 is increased by 1.6%?

Answers

Answer:

27.432

Step-by-step explanation:

27 = 100%

divide by one hundred to get one percent

0.27 = 1%

Divide this by two to get 0.5%

0.135 = 0.5%

Divide by 5 to get 0.1%

0.027 = 0.1%

Add

0.27 + 0.135 + 0.027 = 0.432 =1.6%

Add 0.432 to 27

27.432

Here is the Question:
The system y = 4x - 7 and 2y = ax + b has no solution. Determine the value(s) of a and b for which this is true.

Answers

Answer:

a = 8

b ≠ 18

Step-by-step explanation:

y = 4x - 7

2y = ax + b

For there to be no solution, the lines (if graphed) should be parallel meaning that their slopes are equal but the y-intercepts are different

y = mx +b is the equation of a line where m is the slope and b is the y-intercept

Multiply the first equation by 2

2y = 8x - 14

2y = ax + b

So a has to equal 8

b can be anything except 14 (otherwise the lines would be the same)

9514 1404 393

Answer:

a = 8b ≠ -14

Step-by-step explanation:

Multiply the first equation by 2 and you get ...

  2y = 8x -14

Compare to the second equation ...

  2y = ax +b

The pair of equations will have no solution if they describe parallel lines. That is, a = 8 and b ≠ -14.

__

For a ≠ 8, the lines will intersect and there will be one solution.

For a = 8 and b = -14, the lines will be coincident, and there will be infinite solutions.

In a system of equations, two different lines intersect. How many solutions does the
system have?
a) Zero
b) One
c) Two
d) Infinitely many

Answers

A) One
If the line is intersecting and is parallel then the line will only intersect once at one point

The perimeter of a triangle is 27. Each side of the triangle has length 2x-3. What is the value of x?

Answers

Answer:

x=6

Step-by-step explanation:

To find the perimeter of the triangle you need to add up all the sides, so if all the sides are 2x-3 the equation will look like this;

2x-3+2x-3+2x-3=27

which when combining like terms will leave it to be;

6x-9=27

Than move all the factors besides x over to the right side;

6x-9+9=27+9

6x = 36

6x/6 = 36/6

x = 6

so your answer will be x=6
