Answer:

First, in one year you win:

$28,460

Now yearly we can subtract:

3.6% for the taxable income

1.7% for the gross pay:

(Those apply to the complete annual salary)

3.6% + 1.7% = 5.3%

This in decimal notation is 0.053, then paying those two things we have left:

$28,460*(1 - 0.053) = $26,951.62

Now we need to subtract the union dues, which are $156 per year.

$26,951.62 - $156 = $26,795.62

Now, this is yearly, and we want to know the weekly pay.

In one year we have 365 days.

One week has 7 days.

Then in one year, we have:

365/7 = 52.14 weeks.

Then the pay per week is:

$26,795.62/52.14 = $513.92

And now, each week we must pay $88 for state personal deductions, and $67 for FIT.

Then we have:

$513.92 - $88 - $67 = $358.92

Then the net pay for each weekly pay period is: $358.92

Answer:

No

Step-by-step explanation:

2 is a positive whole number with a value greater than 1. 3/4 is NOT greater than 1. So 2 is greater than both 0 AND 3/4 and cannot be between the two numbers.

No, Jan is wrong because 2 is not in between 0 and 3/4 on a number line.

Number line is a horizontal line where numbers are marked at equal intervals one after another form smaller to greater.

Given that;

Jan says that 2 is between 0 and 3/4 on a number line.

Here, The numbers on the number line are 0 and 3/4.

⇒ 3 / 4 = 0.75

So, We get;

⇒ 2 > 0

And, 3/4 < 2

Thus, The number 2 is not in between 0 and 3/4 on a number line.

Answer:

D

Step-by-step explanation:

mass =250 g abd volume = 50cm^3 = 50 ml

Density = mass/volume

Density = 250/50 =5 g/ml or 5g/cm^3

Answer:

Step-by-step explanation:

Loss is 20%

S.P=Rs60000

C.P=S.P*100/100-loss%

=60000*100/80=Rs75000

So he brought is at Rs75000

Now he wants 12% profit

So

S.P=(100+profit%)/100*C.P

=100+12/100*75000

=112/100*75000=Rs 84000

He will have to sell Rs14000 more to gain profit of 12%

Answer:

28.4 (rounded)

Step-by-step explanation:

7.1 times 7.1 is 50. To calculate area, you need to multiply 2 of the sides. so, that is the side length.

then, you multiply it by 4 for all four sides. that would be 28.4.

Answer:

54 or 30

Step-by-step explanation:

Perimeter is adding all the sides together. Area is multiplying LxW and 50 can be gotten by multiplying 5 by 10, or 25 by 2. So if you went by 5x10, both lengths would be 5 and the widths would be 10 or vice versa. Same goes for if you multiplied 25 by 2.

Answer:

no solution

Step-by-step explanation:

y = 2x - 1 → (1)

y = 2x + 4 → (2)

substitute y = 2x - 1 into (2)

2x - 1 = 2x + 4 ( add 1 to both sides )

2x = 2x + 5 ( subtract 2x from both sides )

0 = 5 ← not possible

This indicates the system has no solution

Answer:

10.8

Step-by-step explanation:

Rounded to the nearest tenth

The length of the longer diagonal of this parallelogram is 10.8.

A parallelogram is a rectangle with two pairs of parallel sides. The lengths of the opposite sides of the parallelogram are equal, and the angles of the opposite sides are the same. Also, the internal angles on the same side of the transversal are complementary. The sum of all internal angles is 360 degrees.

A parallelogram is a simple (non-self-intersecting) quadrilateral with two pairs of parallel sides. The lengths of the opposite or opposite sides of the parallelogram are equal, and the angles of the opposite sides of the parallelogram are equal.

Answer:

He will drive 180 miles in 4 hours. ( I think)

Step-by-step explanation:

If he keeps going at his rate which is 45 mph then if you multiply that by 4 then your answer should just be 180 miles.

Answer:

180 miles

Step-by-step explanation:

so he goes 45 miles per hour

since you need to find 4 hours just multiply 45 by 4

45 x 4 = 180

there's your answer

Answer:

When you flip over the the x-axis, the y-coordinate becomes the additive inverse. I.e. ; if I flipped over the x-axis, a (x,4) would become (x,-4). When you flip over the y-axis the x becomes the additive inverse. (x,4) will become (-x,4)

Answer:

Step-by-step explanation:

The formula for calculating the interior angle of a polygon is expressed as;

sum of internal angle = (n-2)180 where;

n is the number of sides of the polygon in consideration.

Given a 15 sided polygon, n = 15

sum of internal angle = (15-2)180

sum of internal angle = (13)180

sum of internal angle = 2340

Hence kevin is wrong, the correct answer is 2340

Answer:

189.25 in²

Step-by-step explanation:

First, let us find the area of the rectangle.

Area = Length × Width

        = 15 in × 10 in

        = 150 in²

Then let us find the area of the semicircle.

Area = [tex]\frac{1}{2}[/tex] × π r²

         =  [tex]\frac{1}{2}[/tex] × 3.14 × 5 × 5

         = 0.5 × 3.14 × 25

         = 1.57 × 25

         = 39.25 in²

Now let us find the total area of the composite figure.

Total area = Area of the rectangle + Area of the semi-circle.

                 = 150 in² + 39.25 in²

                 = 189.25 in²

Answer:

y = -2000x + 30,000 is the correct answer.

Step-by-step explanation:

For slope intercept equation we first determine the intercept on the axis.

The intercept is a constant value, c, in the slope intercept equation.

In this case, the constant value is 30,000.

Our height, y, is directly proportional to minute,x, taken to descend.

y = mx + c

M is the slope/ gradient which is -2000 since the airplane is descending.

Since the plane descends 2000 feet per minute, its height after 1 minute should be:-

y = -2000(1) + 30,000

y = 28,000

This calculation confirms our above answer.
