Answer:

The monthly net pay is [tex]\$1555[/tex].

Step-by-step explanation:

Step 1 :

Quintina decided to increase the deduction percentage of her federal income tax rate from [tex]14\%[/tex] to [tex]16\%.[/tex]

Quintina gross pay per month is [tex]\$2,100[/tex]

[tex]16\%[/tex] is written in the decimal form.

[tex]=\frac{16}{100}[/tex]

[tex]=0.16[/tex]

Federal income tax

[tex]=0.16[/tex]  × Gross pay

[tex]=0.156[/tex]  × [tex]2100[/tex]

[tex]=336[/tex]

Step 2:

Monthly net pay = Gross pay- Federal income tax - State Income Tax – social Security- Medicare.

[tex]=2100-336-89-85-35[/tex]

[tex]=2100-545[/tex]

[tex]=\$1555[/tex]

Therefore, the monthly net pay is [tex]\$1555.[/tex]

Answer:

3.25

Step-by-step explanation:

1 hong kong dollar = 0.13 cents in us dollars

0.13x25=3.25

The value of 25 Hong Kong dollars in U.S dollar is $3.1969

Given that :

$1 = 7.82 Hong Kong dollars

Let the equivalent Number of U.S dollars = p

This means that :

$1 = 7.82 Hong Kong dollars

$1 = 7.82 Hong Kong dollars $p = 25

Cross multiply :

25 × 1 = 7.82 × p

25 = 7.82p

Divide both sides by 7.82

25 / 7.82 = p

p = $3.1969

Hence, 25 Hong Kong dollars is 3.1969 U.S dollars.

Answer:

270

Step-by-step explanation:

by using the proportion rule:

let X be the number of qualified teachers then

1:2=X=540 i.e.

1/2 =  X/540

by cross multiplication,

540x1=2xX

540=2X i.e.

X=540/2

X=270

There are 270 qualified teachers.

To solve this, we would apply the knowledge of proportion.

It is simply a way of stating that two ratios are of equal measure.

For example, [tex]a:b = x:y[/tex] or [tex]\frac{a}{b} = \frac{x}{y}[/tex]

Applying the following proportion rule given that:

Ratio of qualified teachers to unqualified teachers is 1:2.

Number of unqualified teachers = 540

Let number of qualified teachers be represented by x.

Therefore:

[tex]\frac{1}{2} = \frac{x}{540}[/tex]

Cross multiply

[tex]2x = 540(1)[/tex]

Divide both sides by 2

[tex]\frac{2x}{2} = \frac{540}{2} \\x = 270[/tex]

Therefore, the number of qualified teachers is 270.

Answer:

49.12 ft^2

Step-by-step explanation:

The triangle:

Area = 1/2 * base * height

= 1/2 * 6 * 8

= 24

The semicircle:

Area = 1/2 * 3.14 * 4^2

= 25 .12

Total area = 24 + 25.12

Answer:

LCD = 8

Step-by-step explanation:

All you have to do is times both the denominator and numerator of 1/2 by 4.

So 1 times 4 = 4 and 2 times 4 is 8.

Answer:

Step-by-step explanation:

In order for the total displacement to be zero, the amount of forward displacement must be equal and opposite to the amount of backward displacement. Since the steps are the same length, they must be equal in number.

Half of the 10 steps were forward, and the other half were backward.

  5 steps forward; 5 steps backward.

Math develops from an effort to model the real world. It would probably give you some insight into this problem if you were to physically take some steps to see how many forward and backward you would need to end where you start.

2 by 25 feet.

Step-by-step explanation:

Let L and W be the length and the widht of the field

we want W = L + 23 and W x L = 50

So

(L + 23) x L = 50

[tex]L^2 + 23L = 50\\L^2+23L-50 =0\\(L+25)(L-2)=0\\L=-25 \text{ or } L = 2[/tex]

Since L must be positive then L =2 and W = 2 + 23 = 25.

Answer:

2 miles and 88 yards.

Step-by-step explanation:

4 has 2*2 as prime factors

5 is prime

10 has 2 and 5 as prime factors

Thus, the lowest common denominator will be 2*2*5

3/4=15/20

3/5=12/20

7/10=14/20

Now that we have three fractions with the same denominator, we can add the numerators

15+12+14=41

So 41/20ths

That’s 2 and 1/20th

So the final answer is 2 miles and 88 yards! :)

Answer:

  123°

Step-by-step explanation:

Each of the parts of the trisected angle is equal to the others.

  ∠PQT = ∠TQS

  7x +6 = -2x +8y -13

  9x -8y +19 = 0 . . . . . . subtract the right-side expression

  ∠TQS = ∠RQS

  -2x +8y -13 = 5x +2y

  7x -6y +13 = 0 . . . . . . subtract the left-side expression

__

These equations can be solved by any of your favorite methods to give ...

  (x, y) = (5, 8)

Then the angle measures are ...

  ∠PQT = 7x +6 = 7(5) +6 = 41

  ∠TQS = -2x +8y -13 = -2(5) +8(8) -13 = 64 -23 = 41

  ∠RQS = 5x +2y = 5(5) +2(8) = 41

The measure of angle PQR is 3·41° = 123°.

Additional comment

Using Cramer's rule, the solution is ...

  x = (-8(13) -(-6)(19))/(9(-6) -7(-8)) = 10/2 = 5

  y = (19(7) -13(9))/2 = 16/2 = 8

I prefer a method like this, or the graphical solution, when the numbers don't lend themselves to substitution or elimination.

__

Obviously, once we have found angle PQT, we can simply multiply it by 3 to find angle PQR. We chose to compute the values of the other angles as a check on our math.
