Answer:

Por 3 meses Elena pagó $624.

Step-by-step explanation:

Elena paga por su recibo de teléfono $ 132,80 y de luz $ 75,20. Por lo que, para obtener lo pagado por Elena en ese mes por sus recibos se debe sumar ambos importes:

132,80 + 75,20= 208

Entonces en ese mes Elena pagó $208.Si 3 meses del año pagó el mismo importe, entonces debes multiplicar $208 por 3.

208*3= 624

Entonces, por 3 meses Elena pagó $624.

Answer:

Part A

Rahul by 3.6 km

Part B

The distance between A and D, through place C, d are;

The distance between A and D in meters, m = 44,500 m

The distance between A and D in centimeters, cm = 4,450,000 cm

The distance between A and D, in kilometers, km = 44.5 km

Step-by-step explanation:

Part A

The details of the journeys are;

The distance of A from B = 10.8 km

The distance of B from C = 15.5 km

The total distance Ramesh traveled, d₁ = The distance of A from B + The distance of B from C

Therefore;

d₁ = 10.8 km + 15.5 km = 26.3 km

The total distance Ramesh traveled, d₁ = 26.3 km

The distances of the journey of Rahul is as follows;

The distance between place A and D = 11.7 km

The distance between place D and C = 18.2 km

The total distance Rahul traveled, d₂ = The distance between place A and D + The distance between place D and C

d₂ = 11.7 km + 18.2 km = 29.9 km

The total distance Rahul traveled, d₂ = 29.9 km

Therefore, given that d₂(29.9 km) > d₁(26.3 km), Rahul travelled more distance than Ramesh

The difference between the distance Rahul travelled and the distance Ramesh travelled, d₂ - d₁ = 29.9 km - 26.3 km = 3.6 km

Therefore;

Rahul travelled more distance than Ramesh by 3.6 km

Part B

The total distance from place A to place D through place C, d₃, is given as follows;

d₃ = The distance from A to B + The distance from B to C + The distance from C to D

∴ d₃ = 10.8 km + 15.5 km + 18.2 km = 44.5 km

The total distance from place A to place D, d₃ = 44.5 lm

The total distance from place A to place D in meters, m = 1000 m/km × 44.5 km = 44,500 m

The total distance from place A to place D in cm = 100 cm/m × 44,500 m = 4,450,000 cm

Answer:

B.) √3/2

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

For questions like this I recommend memorizing the Unit Circle, but for the sake of calculations here's how I do it using a calculator

cos(30) = 0.866025.....

So now I'll just go through the answers and see which is equivalent

A= 1.73...

B= 0.866025....

C=0.57735....

D=0.5

E=0.7071.....

F=1

You can see that B is equivalent.

Answer:

y = -13

Step-by-step explanation:

y = 3x - 1             equation(i)

2x - y = 5            equation(ii)

now substitute the value of y in equation(ii)

2x - y = 5

2x - (3x -1) = 5

2x - 3x + 1 = 5

-x = 5 -1

-x = 4

x = -4

again substitute the value of x in equation (i)

y = 3x - 1

y = 3*-4 - 1

y = -12 - 1

y = -13

AnswerAverage pay per hour 19.15

Step-by-step explanation:

1750 + 2% = 1785 pay increase

1785 x 12 months = 21420 a year

21420 divided by 52 weeks in a year averages to 411.92 weekly

Divide 411.92 by the 45 hours of work is 19.15 per hour

Answer:

He paid $640 out of his total $3,200 for the month.

As a fraction it is (640/3200) which equals (1/5)

We want it as a percentage so we multiply the fraction by 100.

1/5×100=20%

20% is the final answer.

Answer: d. $16.34

Step-by-step explanation:

The table shows that if the wages are between 760 and 780 and there are no withholding allowances, the federal tax is $86.

Luce therefore has a federal tax of $86 as she falls in the bracket described.

If state tax is 19% of this, state tax is:

= 19% * 86

= $16.34

The amount of state tax which is contributed by the Luce for the no federal withholding allowances is $16.34.

Federal income tax is the tax which is used to develop and run the city or country and charged on the citizen residing there  .

A 9-column table with 7 rows is given in the prooblem.

Luce is single and making $763 biweekly. She claims no federal withholding allowances.

This amount is come between the values of $760 and $780.  If we look into the table provided into the problem, the federal tax for this slab is $86.  

Now the state tax is 19% of the federal tax. Thus, the 19 percent of the federal tax $86 is,

[tex]\rm tax=86\times\dfrac{19}{100}\\tax=16.34[/tex]

Thus the amount of state tax which is contributed by the Luce for the no federal withholding allowances is $16.34.

6^{-3}

[tex]=\frac{1}{6^3} \\=\frac{1}{216}[/tex]

Answer:

13 exercises

Step-by-step explanation:

The number of exercises in the exam = 20

The points received for questions solved correctly = 8 points

The points taken off for exercises solved wrong = 5 points

The number of points Ben has = 13 points

Let 'c' represent the number of exercises he solved correctly and let 'w' represent the number of exercises he solved wrong, we have;

0 < c + w ≤ 20...(1)

8·c - 5·w = 13...(2)

Given that 5·w has either a 0 or 5 as the unit digit, and x3 = x8 - 5, such as 13 = 18 - 5, we have that the last digit of 8·c is 8, and the last digit of 5·w is 5

The products of 8 with '8' as the unit are, 8 × 6, 8 × 11, and 8 × 16

Therefore, when c = 6, and w = 7, we get;

8 × 6 - 5 × 7 = 13

The number of exercises Ben solved, c + w = 6 + 7 = 13 < 20

When c = 11, we get;

8 × 11 - 5 × 15 = 13

11 + 15 = 26 > 20

The number of exercises Ben solved = 13 exercises

Answer:

x = 8

Step-by-step explanation:

Given 2 intersecting chords.

Then the product of the parts of one chord is equal to the product of the parts of the other chord, that is

14(2x + 2) = 12(2x + 5) ← distribute parenthesis on both sides

28x + 28 = 24x + 60 ( subtract 24x from both sides )

4x + 28 = 60 ( subtract 28 from both sides )

4x = 32 ( divide both sides by 4 )

x = 8
