Answer:

B) 538, 650

Step-by-step explanation:

Given:

Errors on tax returns filed manually  = 20%

Errors on tax returns filed electronically  = 0.05%

Tax return filled in each way = 2.7 million

Manual filing:

2,700,000 x 20% = 2,700,000*0.2 = 540,000

Electronic filing:

2,700,000 x 0.05% = 2, 700,000*0.0005 = 1,350

Error difference = 540,000 - 1,350 = 538,650

There will be 538,650 more erroneous tax returns filed manually than there are filed electronically.

Thank you.

The difference between manually filed return and the electronically filed return is [tex]\boxed{538650}[/tex]. Option (b) is correct.

Answer:

The percent error of Jocelyn's estimate is 2.14 .

Step-by-step explanation:

Formula

[tex]Percentage\ error = \frac{Error\times 100}{exact\ value}[/tex]

Where

[tex]error = \left | approx\ value - exact\ value \right |[/tex]

As given

Jocelyn estimates that a price of wood measures 5.5 cm.

If it actually measures 5.62 cm.

approx value =  5.5 cm

exact value = 5.62 cm

Put in the error formula

[tex]error = \left | 5.5 - 5.62 \right |[/tex]

[tex]error = \left | -0.12\right |[/tex]

error = 0.12

Put in the formula

[tex]Percentage\ error = \frac{0.12\times 100}{5.62}[/tex]

[tex]Percentage\ error = \frac{12}{5.62}[/tex]

Answer:

12.5%

Step-by-step explanation:

sum the parts of the ratio 1 + 3 + 4 = 8 parts

8 parts represents 100%, hence

1 part = [tex]\frac{100}{8}[/tex] = 12.5% ← Andy's percentage of the total

Andy Taylor's share in the ratio of 1:3:4 results in him receiving 12.5% of the total team payment.

The question is about the sharing of a total team payment between Andy Taylor and Ben in the ratio of 1:3:4. To find out what percentage Andy receives, we first need to establish the total parts in the ratio. The ratio 1:3:4 sums up to 8 parts in total. Andy's share is represented by 1 part out of these 8. To find the percentage, we divide Andy's 1 part by the total 8 parts, multiply by 100, giving us 12.5%. This means that Andy receives 12.5% of the total team payment.

Answer:

The numbers are 11 and 7

Step-by-step explanation:

To find these, use the statements to create equations in standard form.

3x + y = 40

x - y = 4

Now that we have these two, we can add them together and get the y's to cancel out.

3x + y = 40

x - y = 4

-------------------

4x = 44

x = 11

Now that we have the first number as 11, we can solve for y using either equation.

x - y = 4

11 - y = 4

-y = -7

y = 7

Answer:

The equation of the line would be y = 5x - 28

Step-by-step explanation:

First, we need to know that perpendicular lines have opposite and reciprocal slopes. Give that information, we know that the new line will be the reciprocal and opposite of -1/5. This would be 5. Now that we have that information, we can use it along with a point to fill in the point-slope form of the equation.

y - y1 = m(x - x1)

y - 2 = 5(x - 6)

Then we must solve for y.

y - 2 = 5(x - 6)

y - 2 = 5x - 30

y = 5x - 28

The new pentagon has a perimeter of 27 centimeters.

To find the perimeter of a regular pentagon, we multiply the length of one side by the number of sides. In this case, the perimeter is 18 centimeters, so each side of the pentagon is 18/5 = 3.6 centimeters long.

When this pentagon is dilated by a scale factor of 3/2, each side of the new pentagon will be 3/2 x 3.6 = 5.4 centimeters long.

Therefore, the new pentagon has a perimeter of 5.4 x 5 = 27 centimeters.

Answer:

95

Step-by-step explanation:

We have been given a diagram triangle in which measurement of few angles in terms of x are given.

Using those we need to find the exterior angle but before that we need to find the value of x.

We know that exterior angle is equal to sum of two distant interior angles of that triangle so we can write:

(8x+15)=(3x+20)+(4x+5)

8x+15=3x+20+4x+5

8x+15=7x+25

8x-7x=25-15

x=10

Now plug x=10 into exterior angle 8x+15

8x+15=8*10+15=80+15=95

Hence final answer is 95.

Do you ever have a nice "fist", meaning you have very neat handwriting.

You are told that A to MSG = B to MSG

So

Equation

3x - 10 = x + 4

Solution

Subtract x from both sides

3x - x - 10 = x - x + 4             Simplify

2x - 10 = 4                             Add 10 to both sides

2x - 10 + 10 = 4 + 10              Simplify

2x = 14                                   Divide by 2

2x/2 = 14/2

Answer:

The no. of adult's tickets sold is 25.

The no. of adult's tickets sold is 247

Step-by-step explanation:

Given :

Tickets for a basketball game cost $2 for students and $5 for adults.

The number of students was 3 less than 10 times the number of adults.

The total amount of money from ticket sales was $619.

To Find : No. of each ticket were sold

Solution :

Let x be the no. of the student's tickets sold

Let y be the no. of adult's tickets sold

Since we are given that The number of students was 3 less than 10 times the number of adults.

⇒ x = 10y -3 --(A)

Now cost of 1 student's ticket is $2

Thus, cost of x student's ticket is $2x

Now cost of 1 adult's ticket is $5

Thus,cost of y adult's ticket is $5y

Since we are given that the total amount of money from ticket sales was $619.

⇒2x +5y =619 ---(B)

Solving equation A and B by substitution method :

putting value of x from (A) in (B)

We get :

⇒2( 10y -3) +5y =619

⇒20y-6+5y= 619

⇒25y = 625

⇒y = 625/25

⇒y=25

Thus,  the no. of adult's tickets sold is 25.

Putting value of y in equation A to get value of x .

⇒x = 10(25) -3

⇒x = 247

Thus the no. of adult's tickets sold is 247

Answer:

y=1 for [tex]y\leq 1[/tex]

Step-by-step explanation:

We can solve an inequality much like we solve an equation. We will use inverse operations to isolate y. If we need to divide by a negative then we will need to flip the inequality.

[tex]2y+9\leq 11\\2y+9-9\leq 11-9\\2y\leq 2\\\frac{2y}{2}\leq  \frac{2}{2} \\y\leq 1[/tex]

First, we moved 9 across the equal sign to combine it with 11 by subtracting by 9 from both sides.

Second, we divided both sides by 2.

[tex]y\leq 1[/tex] is the solution. All solutions equal to 1 and less than 1 will work.

1.) 64

2.) x= -5+4i and x= -5-4i

3.) (4x+3iy)(4x-3iy)

Answer:

When we are completing squares, we need to divide by 2 the linear term and then find its square power, that's the term we need to add on both sides of the equality, as follows

[tex](\frac{16}{2})^{2} =(8)^{2}=64[/tex]

Basically, we need to add the number 64 both sides

[tex]x^{2} +16x+64=18+64[/tex]

The given equation is

[tex]x^{2} +10x+41=0[/tex]

We need to apply the quadratic formula to solve this equation

[tex]x_{1,2} =\frac{-b(+-)\sqrt{b^{2}-4ac } }{2a}[/tex]

Where [tex]a=1[/tex], [tex]b=10[/tex] and [tex]c=41[/tex]. Replacing these values, we have

[tex]x_{1,2} =\frac{-10(+-)\sqrt{10^{2}-4(1)(41) } }{2(1)}\\x_{1,2} =\frac{-10(+-)\sqrt{100-164 } }{2}=\frac{-10(+-)\sqrt{-64} }{2}[/tex]

There we need to use complex number, to transform the subradical number in a positive number

[tex]x_{1,2}=\frac{-10(+-)\sqrt{64}i }{2}=\frac{-10(+-)8i}{2}\\ x_{1,2}=-5(+-)4i[/tex]

Therefore, the complex solutions are

[tex]x_{1}=-5+4i\\ x_{1}=-5-4i[/tex]

The given expression is

[tex]16x^{2} +9y^{2}[/tex]

To solve this expression, remember that [tex]i=\sqrt{-1}[/tex]

First, we expresse both squares uniformly,

[tex]16x^{2} +9y^{2}=(4x)^{2}+(3y)^{2}[/tex]

But, we know that [tex]-(-1)=1[/tex], so

[tex](4x)^{2}+(3y)^{2}=(4x)^{2}-(-1)(3y)^{2}[/tex]

Then,

[tex](4x)^{2}-(-1)(3y)^{2}=(4x)^{2}-(3y)^{2}i^{2}[/tex], because [tex]i^{2}=-1[/tex]

Therefore, the expression with complex numbers is

[tex](4x)^{2}-(3iy)^{2}\\\therefore (4x+3iy)(4x-3iy)[/tex]

Answer:

Step-by-step explanation:

The population in 1999 was 10200.

Given is that the population of at a town has grown 2% each year. In 1998, the population of the town was about 10,000 people.

Let the population be in 1999 be {x}. Then, we can write -

{x} = 10000 + {2% of 10000}

{x} = 10000 + {2/100 x 10000}

{x} = 10000 + 200

{x} = 10200

Therefore, the population in 1999 was 10200.
