Answer:

Hello, so the answer is 21.

Step-by-step explanation:

Okay so first we want to do it order, so the order you do it in is the order of PEMDAS which stands for  Parentheses, Exponents, Multiplication, Division , Addition and Subtraction.

So in this situation we have parenthesis, multiplication, subtraction and addition, so we start with the parenthesis, (8 x 3) which is 24. So then we move on to +6 (positive six) and -9 (negative 9) basically -9 minus 6 is -3.

Sooo now we have -3 and 24. The three is negative because -9 minus 6 is -3, and you have to put the sign of the bigger number.

Now, 24 minus 3 equals 21. So there we have it :)

Hope I helped!

Answer:

x = 9

Step-by-step explanation:

2x + 15 = 33

2x = 33 - 15

2x = 18

x = 18/2 = 9

Answer:

x=9

Step-by-step explanation:

2x+15=33

Subtract 15 from each side

2x+15-15=33-15

2x=18

Divide by 2

2x/2 = 18/2

x = 9

Answer:

5.143m

Step-by-step explanation:

Since we are not asked what to find, we can find the height of the building

Given

Length of ladder (hypotenuse) = 6m

angle of elevation = 59°

Required

Height of building H (opposite)

Using the SOH CAH TOA identity

sin theta = opp/hyp

sin 59 = H/6

H = 6sin59

H = 6(0.85716)

H =5.143

Hence the height of the building is 5.143m

Second option is correct. That is the probability of being below 514 with the mean  474  and standard deviation 32 is 0.8944.

A function that represents the distribution of many random variables as a symmetrical bell shaped graph.

The normal distribution is a probability distribution, so the total area under the curve is always 1 or 100%.

A z-score is a numerical measurement that describes a value's relationship to mean of a group of values.

z = (x -μ)/σ

where,

z is standard score

x is observed value

μ is mean of sample

σ is standard deviation of sample

According to the given question

we have

x = 514

μ = 474

and

σ =32

therefore,

Z- score will be

Z = (514 -474)/32 = 1.25

So, the area under the normal distribution curve z<1.25

⇒ P(x<1.25) = P(Z<1.25) = 0.894

Hence, second option is correct one. That is, the probability of being below 514 if the mean of a normal distribution is 474and the standard deviation is 32 is 0.894.

Explanation:

a = 9 and b = 40 are the legs of the right triangle

c is the unknown hypotenuse

Use the pythagorean theorem to find c

a^2 + b^2 = c^2

9^2 + 40^2 = c^2

81 + 1600 = c^2

c^2 = 1681

c = sqrt(1681)

c = 41 meters is the length of the hypotenuse

-10x+30+25x

25x-10x+30

15x+30

15(x+2)

Step-by-step explanation:

The factored form of the given expression is 15(x + 2).

An algebraic expression can be obtained by doing mathematical operations on the variable and constant terms.

The variable part of an algebraic expression can never be added or subtracted from the constant part.

The given expression is as below,

−5(2x − 6) + 25x

It can be simplified as follows,

−5(2x − 6) + 25x

= -10x + 30 + 25x

= 15x + 30

= 15(x + 2)

Hence, the given expression can be simplified in factored form as 15(x + 2).

Explanation:

The sides shown by the single tickmark are the same length. That's one "S" of "SSS".

The sides shown with double tickmarks are the same length. This is another "S" of "SSS".

Lastly, the third unmarked sides of each triangle overlap together perfectly. We consider this a shared side. They are the same length due to the reflexive property. This is the third "S" of "SSS".

The order of the "S" terms mentioned above doesn't matter. All that matters is that we have three pairs of congruent sides. This is enough to use the SSS congruence theorem to prove the two triangles are congruent.

Answer:

D = {1, 4, 6, 8, 9}

Step-by-step explanation:

A relationship maps elements from a set (the domain, the set of the inputs) into elements from another set (the range, set of the outputs).

Such that the usual notation is: (x, y)

this says that the relationship maps the element x into the element y.

In this case, we have the relation:

" { (9,1), (4,5), (6,2), (8,6), (1,2)}"

The inputs are the first value for each pair, then the set of the inputs (also called the domain) is:

D = {9, 4, 6, 8, 1}

And we can rewrite this in order to get:

D = {1, 4, 6, 8, 9}

Answer:

10.2

Step-by-step explanation:

The sum of the three angles is 180, since they form a straight line

8x-15  + 58+ 3x+25 = 180

Combine like terms

11x +68 = 180

Subtract 68 from each side

11x+68-68= 180-68

11x =112

Divide by 11

11x/11 = 112/11

x = 10.181818181

x = 10.2

Given info:-In the given figure, points A,B and C are collinear or they are straight line. Where angle ABC , angle DBE and EBC are in formed of linear pair that mean they are 180. And here we are going to find out the value of X?

angle ABD+ angle DBE + angle EBC = 180° {Angles of a linear pair]

⇛(8x-15)°+(58)°+(3x+25)° = 180°

Remove all the brackets in LHS.

⇛8x° - 15° + 58° + 3x° + 25° = 180°

⇛11x° - 15° + 58° + 25° = 180°

⇛11x° - 15° +83° = 180°

⇛11x° + 68° = 180°

⇛11x° = 180° - 68°

⇛11x° = 112

Shift the number 11° from LHS to RHS.

⇛x = 112÷11 ⇛112/11 =

The value of x = 10.181818.. = 10.18 bar
