Answer: d is the answer it

Answer:

x=0

Step-by-step explanation:

x°+65°+109°+136°=310°

we know that this whole equation equals 310.

so we add all the numbers equaling x+174+136=310 : x+310=310

x clearly equals 0 and even then you can subtract 310 from both sides which still gives you 0.

hopefully this helps.

Heya!

Answer:

x° = 0°

Step-by-step explanation:

x°+ 65° + 109° + 136° = 310°

Add all of the degrees on the left side together.

x° + 310° = 310°

Subtract 310° from both sides.

x° + 310° = 310°

    - 310°   - 310°

+ 310° and - 310° cancel out. 310° - 310° is 0.

x° = 0°

So, x° = 310° is your answer.

Speed is the rate at which a body changes its position. The speed by which Marina runs is 4 miles/ hr.

Speed is the rate at which a body changes its position. It is given by the formula,

[tex]\rm{Speed = \dfrac{Distance}{Time}[/tex]

Given to us

Marina can bicycle 19. 5 miles at the same time it takes her to run 6 miles.

Marina bikes 9 miles per hour faster than she runs.

Let the speed of the Marina running be s, and the time is taken to run 6 miles be t.

Time is taken by Marina to cover a distance of 6 miles by running,

[tex]\rm t = \dfrac{6\ miles}{s}[/tex]

Since the speed of Marina's bicycle is 9 miles per hour faster than she runs. Time is taken by Marina to cover a distance of 19. 5 miles by bicycle,

[tex]\rm t = \dfrac{19.5\ miles}{s+9}[/tex]

We know that Marina can bicycle 19. 5 miles at the same time it takes her to run 6 miles. therefore,

[tex]\rm t = \dfrac{6\ miles}{s}= \dfrac{19.5\ miles}{s+9}[/tex]

[tex]\dfrac{6}{s}= \dfrac{19.5}{s+9}[/tex]

Solving the given equation we will get,

[tex]\rm s = 4\ miles/hr[/tex]

Hence, the speed by which Marina runs is 4 miles/ hr.

Step-by-step explanation:

simplify the following expression:  

[tex](5x^4 - 9x^3 + 7x - 1) + (-8x^4 +4x^2-3x + 2) - (-4x^3 + 5x - 1)(2x -7)[/tex]

Final Answer is [tex]480[/tex]

Step-by-step explanation:

Assume that:

First number = x

Second number = 20 - x

Putting the given conditions,

[tex]2x^{2} + 3(20 - x)^{2} [/tex]

Putting the formula (a-b)²=(a²+2ab+b²) in (20-x)²,

[tex]2 {x}^{2} + 3(20^{2} - 2 \times 20 \times x + {x}^{2})[/tex]

[tex] = > 2 {x}^{2} + 3(400 - 40x + x^{2})[/tex]

Opening the brackets,

[tex]2 {x}^{2} + 3 \times 400 - 3 \times 40x + 3 \times {x}^{2} [/tex]

[tex] = > 2 {x}^{2} - 1200 - 120x + 3{x}^{2}[/tex]

[tex] = > (2x^{2} + 3 {x}^{2}) - 120x + 1200[/tex]

[tex] = > 5 {x}^{2} - 120x + 1200[/tex]

[tex] = > - \frac{120}{2 \times 5}[/tex]

[tex] = > - \frac{120}{10} [/tex]

[tex] = > - 12[/tex]

Now substituting the value of x in 5x²-120x+1200,

[tex] = > (5 \times {12}^{2} )-(120 \times 12)+1200[/tex]

[tex] = > (5 \times 144)-(1440)+1200[/tex]

Answer:

4 Cases

Step-by-step explanation:

If they bought 3 cases they would only have 864

Answer:

4 cases

Step-by-step explanation:

Find out how many pencils per case:

1 case = 24 boxes

1 box = 12 pencils

1 case = 24•12 = 288 pencils

Divide the amount of needed pencils (900) by how many per case there are (288) to find how many cases you need:

900÷288=3.125 (or 3 1/8)

Since you can't get a part of a case (for the 1/8 of a case you need), you will need to round up to 4 cases.

Answer:

side = 20 cm

Step-by-step explanation:

Since the triangle is equilateral then the 3 sides are congruent.

Equate the 2 given sides and solve for x

5(x - 3) = 2x + 6

5x - 15 = 2x + 6 ( subtract 2x from both sides )

3x - 15 = 6 ( add 15 to both sides )

3x = 21 ( divide both sides by 3 )

x = 7

then length of side is

2x + 6 = 2(7) + 6 = 14 + 6 = 20 cm

Answer:

20 cm

Step-by-step explanation:

Properties of an Equilateral Triangle

Given information

Find value of x

As side lengths are equal, equate the expressions and solve for x.

   2x + 6 = 5(x - 3)

⇒ 2x + 6 = 5x - 15

⇒ 2x + 6 + 15 = 5x - 15 + 15

⇒ 2x + 21 = 5x

⇒ 2x + 21 - 2x = 5x - 2x

⇒ 21 = 3x

⇒ 21 ÷ 3 = 3x ÷ 3

⇒ 7 = x

⇒ x = 7

Side lengths

Substitute x = 7 into one of the given expressions.

⇒ length of one side:  2(7) + 6 = 20 cm

Prediction for some count is usually expressible as expectation of some random variable. The reasonable prediction for the number of times a white or red marble will be drawn is 54

A  random variable is usually taking some numerical information of each elementary event of the sample space . (map from sample space to real numbers). Its expected value is the best prediction value in most of the cases.

Binomial distributions consists of n independent Bernoulli trials.

Bernoulli trials are those trials which end up randomly either on success (with probability p) or on failures( with probability 1- p = q (say))

Suppose we have random variable X pertaining binomial distribution with parameters n and p, then it is written as

[tex]X \sim B(n,p)[/tex]

The probability that out of n trials, there'd be x successes is given by

[tex]P(X =x) = \: ^nC_xp^x(1-p)^{n-x}[/tex]

For the given case, as the ball being drawn is being replaced too, so we can take all 180 experiments to be independent from each other.

If we call

Success = Event of drawing white or  red marble

Failure = Event of drawing any other marble instead of white or red

Then, each marble drawing event is having two outcomes: success or failure. This makes each drawing a Bernoulli  experiment.

Modelling this situation with binomial distribution would be good.

Let X = number of successes in those 180 experiments.

Thus, we get

[tex]X \sim B(n = 180, p= 0.3)[/tex]

The expectation of random variable X is the best prediction of count of times we will get in those 180 trials.

The expectation of a  random variable is: [tex]E(X) = np[/tex]

Thus, we get:

[tex]E(X) = 180 \times 0.3 = 54[/tex]

Thus, the reasonable prediction for the number of times a white or red marble will be drawn is 54

Arithmetic sequence is done by adding or subtracting the difference. The 12th term of the arithmetic sequence will be 58.

The arithmetic sequence is the series of numbers where every two consecutive terms have the same difference between them.

We know that the nth term of an arithmetic sequence is given as,

[tex]a_n = a_1 + (n-1)d[/tex]

Also, we are given two functions adding the two functions we get,

[tex]f(x) + g(x)\\\\ = 25 + 3(n-1)[/tex]

comparing the sum we get with the arithmetic sequence formula for nth term, we will understand that,

[tex]a_1 + d(n-1)\\25+3(n-1)[/tex]

therefore,

a₁ = 25

and d = 3

that means the first term of the sequence is 25 while the difference between the two terms is 3.

Now, substituting the values in the formula we will get that the 12th terms of the sequence can be written as,

[tex]a_n = a_1 + (n-1)d\\\\a_{12} = 25 + (12-1)3\\\\a_{12} = 25 + 33\\\\a_{12} = 58[/tex]

Hence, the 12th term of the arithmetic sequence will be 58.
