5x Angle addition postulate

Answers

Answer 1

The value of x determined by Angle addition postulate is (x = 25).

What is defined as the Angle addition postulate?The angle addition postulate in geometrical states that if two or more angles are placed side by side with a common vertex as well as a common arm between every pair of angles, the sum of those angles equals the total sum of the resulting angle. For example, if ∠AOB and ∠BOC are adjacent angles on the a common vertex O with OB as the common arm, then we have ∠AOB + ∠BOC = ∠AOC based on the angle addition postulate.

As per the given questions;

The two angles are given as;

∠ABD = 5x + 10

and ∠DBC = 2x - 5

By the angle addition postulate;

The sum of both the angles will be 180.

Put the values;

∠ABD +  ∠DBC = 180

5x + 10 + 2x - 5 = 180

Simplifying;

7x + 5 = 180

7x = 180 - 5

7x = 175

x = 25.

Thus, the values of x is determined as the (x = 25).

The digits that make the given statement true are 3 or 7.

5,156,936 is divisible by 4.5,156,976 is divisible by 4.

What are the rules of divisibility of 4?The basic rule for divisibility by 4 is that if the number formed by the last two digits of a number is divisible by 4, the original number is divisible by 4 as well; this is because 100 is divisible by 4, and so adding hundreds, thousands, and so on is simply adding another number that is divisible by 4.

So, 5,156,9_6 to be divisible by 4:

If the last two digits are divisible by 4, the sum is divisible by 4.As a result, _6 must be divisible by 4.There are two options here: 3 (as in 36) or 7. (as in 76).

Therefore, the digit that makes the given statement true is 3 or 7.

How to determine the discriminant?

For a quadratic equation:

The discriminant is:

D = b^2 - 4ac

If D > 0, we have two real solutions.

If D = 0 we have one real solution (it is thought as two equal solutions)

if D < 0, we have two complex solutions.

In this case, the quadratic equation is:

How to determine the value

From the information given, we have that;

Scale drawing was used0. 25 inches represents 2 feetThe length of the building is 250 feet

Then,

If 0. 25 inches = 2 feet

Then x inches = 250 feet

cross multiply
x × 2 = 0. 25 × 2500

Multiply through, we have;

2x = 62. 5

Make 'x' the subject by dividing both sides by 2

How are time, distance, and speed related?

Speed indicates how quickly something or someone is moving. Speed is calculated as follows: speed = distance * time. Following are the relationships between time, distance, and speed: Distance is directly related to speed and time. Time and speed are also negatively related. Speed is what it means. the speed at which an object's location changes in any direction. The distance traveled in relation to the time it took to travel that distance is how speed is defined. Since speed simply has a direction and no magnitude, it is a scalar quantity. Distance is the sum of an object's movements, regardless of direction. The flow of events from the past into the future is known as time. Time only ever moves in one way. Time can go either forward or backward, but not both.

You roll a number cube. What is the probability that you roll an even number or a number less than 5?

Answers

Let’s first see the probability of landing an even number. We have 6 sides, and 3 are labeled with an even number. So our chances of rolling a number cube are 3/6 (or 1/2 when simplified).

Next, the probability of rolling a number less then five is 4/6 (or 2/3 simplified), since we have 4 sides labeled with a number less than 5.

To compute two or more probabilities, we multiply them. In this case, the fractions already share the same denominator, 6 (because it’s a cube with 6 sides). So we get:

3/6 * 4/6

We then square 6, which is 36, and multiply 3 by 4, which is 12. This gives us 12/36, which is 1/3 in simplified form.

So there’s out answer: 1/3.

Answers

The simple interest for R 7,500 is R 1, 800, and she will get it at 3 years with interest of 8%.

Simple interest:

Simple interest means the method of calculating the interest amount for a particular principal amount of money at some rate of interest.

The formula used to calculate the simple interest is

SI = P × R × T

P = The principal is the amount that initially borrowed from the bank or invested.

R = Rate is the rate of interest at which the principal amount is given to someone for a certain time.

T= Time is the duration for which the principal amount is given to someone.

Given,

Cynthia receives a gift of r 7, 500 she decides to invest it for 3 years, she is offered two saving at 8% interest.

Given f(x)=x²-3x - 23 and
g(x)=x-1, find (fog)(x).

Answers

The required function is (fog)(x) = x^2 – 5x – 19  

We have been given two functions which are:

 f(x) = x^2 – 3x – 23

 g(x) = x – 1

We need to find (fog)(x) which is also equal to f(g(x)).

In this, we have to replace x with the function g(x) in the function, f(x). numerically

    f(g(x)) = g(x)^2 – 3g(x) – 23    

Now we will write the value of g(x) in the above equation. We will get

         f(g(x)) = (x-1)^2 – 3(x-1) – 23

         f(g(x)) = x^2 + 1 – 2x – 3x + 3 – 23

         f(g(x)) = x^2 – 5x – 19

Hence  (fog)(x) = x^2 – 5x – 19  is the required function.
