Answer:

Step-by-step explanation:

that's an equilateral triangle, 3 equal side and 3 equal angles of 60°,

so 10x + 20 = 60

solve with an equation

10x + 20 = 60

10x = 60 - 20

10x = 40

x = 40 : 10

x = 4

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

check

10 * 4 + 20 =

60°

the answer is good

Step-by-step explanation:

m∠3 = 7x - 10

m∠6 = 5x + 10

m∠3 = m∠6

7x - 10 = 5x + 10

7x - 5x = 10 + 10

2x = 20

x = 20/2 = 10°

Answer:

r = -13

Step-by-step explanation:

Step 1: distribute the signs & terms outside the parenthesis. on the left side, distribute a - sign (same thing as -1) and on the right side distibute -7

12 - (3r) - (+2) = (-7)r + (-7)6

Step 2: algebraically simplify

10 - 3r = -7r - 42

52 = -4r

r = -13

10% of 200 is 20 so 23% of 200 is 46

An exponential decay function that represents the population after t years is [tex]\rm f (x) = 250000 (0.965)^t[/tex].

An exponential function can be represented in the form f(x) = aˣ.

The population of a city was 250,000

Rate of decay is 3.5%

100 -3.5 = 96.5%

The population after t years is represented by the function

Answer:

Step-by-step explanation:

∠AHE + ∠AHK = 180    {linear pair}

6x + 7 + 35 = 180

6x + 42 = 180

          6x = 180 - 42

          6x = 138

            x = 138/6

            x = 23

Answer:

15 in

Step-by-step explanation:

You have to use pythagoras' theorem, which is a^2=b^2+c^2 (a being the hypotenuse), because it is a right-angled triangle.

so you do 9^2+12^2, which equals 225. Then you square root that to get 15.

The required answer would be the sum of 5, and 4 is divided by 2 as per the PEMDAS rule which is the correct answer would be option (A)

PEMDAS rule states that the order of operation starts with the calculation enclosed in brackets or the parentheses first. Exponents (degrees or square roots) are then operated on, followed by multiplication and division operations, and then addition and subtraction.

We have been given that expression as

⇒ 5 + 4 ÷ 2

As per the PEMDAS rule,

We have to apply the division operation to terms 4 and 2,

⇒ 5 + 4 /2

⇒ 5 + 2

Apply the addition operation, and we get

⇒ 7

Therefore, the required answer would be the sum of 5, and 4 is divided by 2.

Answer:

The ones you circled are right I believe its just small errors in your notations. I am not sure if the justifications are correct or not.

4 might just be a labelling of the line error. Say line AD is parallel to line BE and line AC is parallel to BD

6 all the lines you circled are all parallel to each other, not two separate pairs

Answer:

The distance is 4 units.

Step-by-step explanation:

Let the distance between the two points (x₁, y₁) and (x₂, y₂) is

d = √(x₂ - x₁)² + (y₂ - y₁)²

Here, the given points are (2,8) and (6,8), therefore,

x₁ = 2, x₂ = 6,

y₁ = 8, y₂ = 8

d = √(x₂ - x₁)² + (y₂ - y₁)²

d = √(6 - 2)² + (8 - 8)²

d = √(4)² + (0)²

d = √16

d = 4

Thus, The distance is 4 units.

Step-by-step explanation:

Let M (-12,5) be the given point and O (0,0) be the origin.

The equation isn't written out so I can't be sure but here are possible answers.

2.2 divided by 6 is 0.36. 0.36 minus 2 is -1.64.

6 minus 2 is 4. 2.2 divided by 4 is 0.55.

The value of P(B|A) is 0.25.

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.

The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.

The degree to which something is likely to happen is basically what probability means.

We have P(A) = 0.40 and P(B) = 0.5

and, P(A and B) = 0.10

Using Conditional Probability

P(B|A) = P(A ∩ B)/P(A)            

Substitute the values of P(A), P(B) and P(A ∩ B),

P(B|A) = 0.10/ 0.40

P(B|A) = 0.25
