Answer:

[tex]39.29\ \text{km/h}[/tex]

Step-by-step explanation:

s = Speed of the train

m = Money spent on maintanence

[tex]s\propto m^{\dfrac{1}{3}}[/tex]

Let k be the constant of proportionality so

[tex]s=k (m)^{\dfrac{1}{3}}[/tex]

Now a case is given where 25 km/hr is possible on a stretch for which 450,000 is spent so

s = 25

m = 450000

[tex]s=k (m)^{\dfrac{1}{3}}\\\Rightarrow k=\dfrac{s}{m^{\dfrac{1}{3}}}\\\Rightarrow k=\dfrac{25}{450000^{\dfrac{1}{3}}}\\\Rightarrow k=0.326[/tex]

Now when m = 1750000

[tex]s=k (m)^{\dfrac{1}{3}}\\\Rightarrow s=0.326\times 1750000^{\dfrac{1}{3}}\\\Rightarrow s=39.29\ \text{km/h}[/tex]

The maximum speed of the train would be [tex]39.29\ \text{km/h}[/tex].

Answer:

See Explanation

Step-by-step explanation:

Since both the arcs centered at A and B are drawn as radius AB.

Therefore, AB = BC = AC

So, triangle ABC will be an equilateral triangle.

Since, AB = 5 CM

THEREFORE,

AC = 5 CM

BC = 5CM

Measure of each angle of equilateral triangle is 60°

Therefore,

Angle A = 60°

Angle B = 60°

Angle C = 60°

Step-by-step explanation:

m< I = m < 2 = m < 3

7y+16 = 2X

7y - 2x +16 = O ............I

7y +16 = 4X _30

7y -4 x + 46 = 0 ...............2

solve eq I,2

2 X - 30= o

X= 15

substitute in I

7X= 14

Answer:

$4000 in product sales

Step-by-step explanation:

[tex]\frac{40}{500} =\frac{320}{x} = 4000[/tex]

Answer:

$4000

Step-by-step explanation:

i) Calculate if $1 = ? commission

500/40 = $12.5

$1 = $12.5 commission

ii) If the commission $320,

320×12.5=4000

His product sales need to be $4000

Answer:

x = -5

Step-by-step explanation:

9(x+4)=1+2x

9x+36 = 1 + 2x

35 = -7x

Divide

-5 = x

x= -5

[tex] \: \: \: \: \: \: \: 9(x + 4) = 1 + 2x \\ \\ = > 9x + 36 = 1 + 2x \\ \\ = > 9x - 2x = 1 - 36 \\ \\ = > 7x = ( - 35) \\ \\ = > x = (- \frac{35}{7} ) \\ \\ = > x = \green{\boxed{ - 5}}[/tex]

Answer:

x = 1/3

Step-by-step explanation:

Move all terms containing x to the left side of the equation.

8+6x=10

Move all terms not containing x to the right side of the equation

6x=2

Divide each term by 6 and simplify.

Exact Form:

x=1/3

Decimal Form:

x=0.3333333333

Answer:

A

Step-by-step explanation:

Answer:

m∠4 = m∠3 = 74° (vertically opposite angles are equal)

m∠8 + m∠3 = 180° (linear pair)

m∠8 + 74° = 180°

m∠8 = 180° - 74°

m∠8 = 106°

m∠7 = m∠8 = 106° (vertically opposite angles are equal)

m∠2 = m∠3 = 74° (alternate interior angles are equal)

m∠1 = m∠2 = 74° (vertically opposite angles are equal)

m∠6 + m∠1 = 180° (linear pair)

m∠6 + 74° = 180°

m∠6 = 180° - 74°

m∠6 = 106°

m∠5 = m∠6 = 106° (vertically opposite angles are equal)

hope it helps you❤

Options:

A. At least $30,000

B. At most $30,000

C. Less than $30,000

D. More than $30,000

Answer:

A. At least $30,000

Step-by-step explanation:

Given the inequality :

2x + $10,000 ≥ $70,000 ;

Where x salary of an employee ;

Phrase which describes the employee's salary, x

2x + 10000 ≥ 70000

2x ≥ 70000 - 10000

2x ≥ 60000

x ≥ 60000 / 2

x ≥ 30000

Salary ,x, is greater than or equal to $30000

Answer: 20 pieces of chocolate could be treated for 35 pieces of hard candy.

Step-by-step explanation:

Equation of direct proportion between two quantities x and y :

[tex]\dfrac{x_1}{y_1}=\dfrac{x_2}{y_2}[/tex]

Put [tex]x_1=4,\ y_1=7,\ y_2=35, x_2=x[/tex]

[tex]\dfrac{4}{7}=\dfrac{x}{35}\\\\\Rightarrow\ x=\dfrac{35\times4}{7}\\\\\Rightarrow\ x=20[/tex]

Hence, 20 pieces of chocolate could be treated for 35 pieces of hard candy.

Answer:

The probability that she was on her next roll is 1/2

Step-by-step explanation:

If she does not roll 1,3 or 6, she wins

So if she rolls 2,4 and 6 , she wins

The probability of rolling each is 1/6 each

So the probability of rolling any of the three will be:

1/6 + 1/6 + 1/6 = 3/6 = 1/2

If you are trying to find out how fast she ran you need to compare it to the total area of land she ran.

2 -[tex]\sqrt{3}[/tex]

7-4[tex]\sqrt{3}[/tex]

=7-2[tex]\sqrt{2x3}[/tex]

=7-2[tex]\sqrt{12}[/tex]

=([tex]\sqrt{3}[/tex])² - 2[tex]\sqrt{3x4}[/tex] + ([tex]\sqrt{4}[/tex] )

=( - [tex]\sqrt{3}[/tex] + [tex]\sqrt{4}[/tex])²

Answer:

The total number of pencils is 6

Step-by-step explanation:

According to the given scenario, the computation of the total number of pencils is as follows:

There are 18 students

And let us assume there is m mechanical pencils that put in each bag

also he put twice of the regular pencil

So if he put the 3 mechanical pencil

So, the total number of pencils is

= 3 × 2

= 6

As it twice of the regular pencil

hence, the  total number of pencils is 6
