A lawyer has an annual income of $154,120. The income tax the lawyer has to pay is 6%. What is the amount of income tax in dollars and cents that the lawyer has to pay

Answers

Answer:

$9,247.20

924,720 cents

Step-by-step explanation:

The computation of the amount of the income tax is shown below:

In dollars

= Annual income × rate of income tax

= $154,120 × 6%

= $9,247.20

Now in cents, it would be

= Annual income × rate of income tax × 100

= $154,120 × 6% × 100

= 924,720 cents

The price to mail a letter at the post office is $0.35 for the first ounce and $0.17 for each additional ounce. Amrit paid $2.05 to mail his letter. How much did the letter weigh?

Answers

As we know the first ounce cost $0.35, we can subtract that from $2.05.

Therefore, $2.05 - $0.35 = $1.70

We can then divide the remaining amount of money by $0.17 to find out how many more ounces the letter weighed.

$1.70/$0.17 = 10

Once we add the ounce before that costed $0.35 to the 10 ounces that we just calculated, we know that Amrit’s letter cost 11 ounces.

Answer:

69°

Step-by-step explanation:

180 - 21 -90 = 69

hope this helps...

Answer: The missing angle is 69°

Step-by-step explanation: When all the angles have their vertex on a straight line, they must add up to 180° They are "supplementary" angles.

The "box" in the corner of an angle is a symbol for "right angle" so that is a way to have a "given" 90°

Knowing that, you can add the "given" 90° + 21° to get 111°

Subtract 111° from 180° to find Angle a:

180 - 111 = 69

The sum of the measures of the angles below is 180∘. A triangle is shown. The first angle measures x degrees. The second angle measures two x minus ten degrees. The third angle measures x plus ten degrees. What is the measure of each angle? Write and solve an equation.

Answers

Answer:

First Angle: 45 degrees, Second Angle: 80 degrees, Third Angle 55 degrees

Step-by-step explanation:

180∘= x+ 2x-10∘+ x+10

180∘=4x

x=45∘

2x-10=80∘

x+10=55∘

The measure of the interior angles of the triangle are 45°, 80° and 55°

respectively.

What is a triangle?

A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.

We know the sum of all the interior angles in a triangle is 180°.

Given, a triangle has interior angles x°, (2x - 10)° and (x + 10)°.

∴ x + (2x - 10) + (x + 10) = 180°.

4x = 180°.

x = 45°.

Answers

Answer:

Option D The pattern is multiplicative because the earnings are 12 times the number of hours worked in each pair of values is correct option.

Step-by-step explanation:

At x-axis we have number of hours worked and y-axis represents earnings in dollars.

We can make the table:

Number of hours worked (x)         earnings in dollars (y)

1                                                                12

2                                                               24

3                                                               36  

4                                                               48

5                                                                60

Now, we need to find the pattern.

If we add 1+ 11 we get 12, but if we add 2+ 11 we get 13 and not 24 so, the pattern is not additive.

Now, if we multiply 1 by 12 (1 x 12) we get 12,

then 2 x 12 = 24

3 x 12 = 36

4 x 12 = 48

and 5 x 12 = 60

The same number if multiplied with x-axis we get y-axis.

So, the pattern is multiplicative. and we are multiplying 12 with the number of hours worked, so the correct option is option D.

Option D The pattern is multiplicative because the earnings are 12 times the number of hours worked in each pair of values is correct option.

Answer:

x = 33

Step-by-step explanation:

Sum of the interior angles of a 5-sided polygon = 540°

Therefore all the interior angles of the given polygon would all be equal to 540°.

Thus:

(4x - 25)° + (3x + 25)° + (2x - 3)° + (4x)° + (3x + 15)° = 540°

Solve for x

4x - 25 + 3x + 25 + 2x - 3 + 4x + 3x + 15 = 540

Combine like terms

4x + 3x + 2x + 4x + 3x - 25 + 25 - 3 + 15 = 540

16x + 12 = 540

16x = 540 - 12

16x = 528

Divide both sides by 16

x = 33

Angel and Jayden were at track practice. The track is 2/5 kilometers around.  Angel ran 1 lap in 2 minutes.  Jayden ran 3 laps in 5 minutes. How far does Jayden run in one minute?

Answers

Answer:

6/25 km in 1 min; or 0.24 km/min

Step-by-step explanation:

The info about Angel is not necessary.

Jayden runs 3 laps in 5 mins

Each lap is 2/5 km, so Jayden runs 3 x (2/5 km) in 5 min = 6/5 km in 5 min.

Distance = rate x time

6/5 km = rate (5 min)

We want to isolate r (rate), so divide both sides by 5 min

6/5 km ÷ 5 min = r

6/5 km (1/5 min) = r

6/25 km/min = r  (notice how the units worked out correctly to km/min)

So, Jayden runs 6/25 km in 1 min.

Answer:

6/25 miles km in a minute

Answer:

45

Step-by-step explanation:

Like last question an isosceles has two angles that are the same. The square indicates a right angle so h=90

180-90=90

90/2=45 so G and E equal 45

Because you are given that one angle measures 90 degrees, this is an isosceles right triangle. Therefore, the other two angles must be equal, and  add up to 90 degrees because an isosceles right triangle is exactly half of a square. Also, all angles in a triangle must add up to 180 degrees. Because of these rules, we can completely ignore the expression for angle G and sufficiently say it is 45 degrees.

Answer:

x = 7

Step-by-step explanation:

10 / 4 = x + 8 / x - 1

[cross multiply]

10 (x - 1) = 4 (x + 8)

[distribute the factors]

10x - 10 = 4x + 32

+ 10 + 10

[add 10 to both sides to cancel out -10]

10x = 4x + 42

-4x -4x

[subtract both sides by 4x to cancel out 4x]

6x = 42

÷6 ÷6

[divide both sides by 6 to simplify 6x to x]

x = 7

________

x = 7 → 10 / 4 = x + 8 / x - 1 →

(7) + 8 / (7) - 1 → 15 / 6 →
