Step-by-step explanation:

Let

x-----> the amount in sales

y----> Cindy Nelson’s salary

we know that

4%=4/100=0.04

so

The linear equation that represent this situation is

y=250+0.04x

case 1) week 1

Sales  $890

For x=890

substitute in the linear equation

y=250+0.04(890)

y=250+35.6=$285.6

therefore

The commission is $35.6

The total salary for week 1 is $285.6

case 2) week 2

Sales  $1,126

For x=1,126

substitute in the linear equation

y=250+0.04(1,126)

y=250+45.04=$295.04

therefore

The commission is $45.04

The total salary for week 1 is $295.04

case 3) week 3

Sales  $975

For x=975

substitute in the linear equation

y=250+0.04(975)

y=250+39=$289

therefore

The commission is $39

The total salary for week 1 is $289

case 4) week 4

Sales  $824

For x=824

substitute in the linear equation

y=250+0.04(824)

y=250+32.96=$282.96

therefore

The commission is $32.96

The total salary for week 1 is $282.96

Answer is letter A

For this case we must find the difference of the following expressions:

[tex]0.00067\\2.3 * 10 ^ {- 5}[/tex]

For the second expression we must run the decimal 5 times to the left, because the exponent is negative, that is:

[tex]0.000023[/tex]

We subtract:

[tex]0.00067-0.000023 = 0.000647[/tex]

Represented in scientific notation we have:

[tex]6.47 * 10 ^ {- 4}[/tex]

Answer:

Option A

Cash flow from operating activities is $43,000. Calculated by adjusting net income for changes in working capital items.

To calculate the cash flow from operating activities using the indirect method, we start with net income and adjust for changes in working capital.

Net Income = $50,000

Changes in Working Capital:

1. Accounts Receivable increased by $30,000, so we subtract $30,000.

2. Inventory decreased by $20,000, so we add $20,000.

3. Amounts Payable increased by $4,000, so we add $4,000.

4. Salaries Payable decreased by $1,000, so we subtract $1,000.

Now, let's calculate the cash flow from operating activities:

Cash flow from operating activities = Net Income + Changes in Working Capital

= $50,000 - $30,000 + $20,000 + $4,000 - $1,000

= $50,000 - $7,000

= $43,000

So, the amount of cash flow from continuing operating activities under the indirect method is $43,000.

Answer:

a. 20.5

Step-by-step explanation:

because this will form a right triangle we can use tan (opposite over adjacent) so an equation we could set up would be tan(70)=25/x

therefore we can just solve the equation which would give us 20.45. so if we round it the answer would be a

Answer:

The correct answer option is a. 20.5 feet.

Step-by-step explanation:

We are given that the angle of elevation of the ladder is 70° and the height of the ladder is 25 feet from the ground.

We are to find the distance of the building from the base of the ladder.

For this, we will use tan:

[tex] tan 70 = \frac { 2 5 } { x } [/tex]

[tex] x = \frac { 2 5 } { tan 7 0 } [/tex]

x = 20.5 feet

The answer is 30.

if 7=a and 2(a+8)

all you need to do is replace a with 7

so the formula would then be 2(7+8)

next you would solve in the parentheses.

2(15)

and 2(15) is the same as 2 x 15

so the answer would be 30

Answer: E. 30

Step-by-step explanation:

Cause a=7 and the equation is 2 (a+8) and it the same as 2 × (7+8) which if you use PEMDAS it's 2 × 15 =30

Answer:

The point (2 - d, y) is on the graph of f(x)

The line x = 2 is the axis of symmetry of the graph of f(x)

Step-by-step explanation:

* Lets explain how to prove that a point lies on a graph Algebraically

- Substitute the value of the x-coordinate of the point in the equation

 of the graph the answer must be equal the y-coordinate of the point

- The function is a quadratic because the greatest power of x is 2,

  then it represented by parabola

- The parabola has a vertex point (h , k), where h is the x-coordinate

  and k is the y-coordinate

- This vertex divides the parabola into two equal parts, then the axis

 of symmetry of the parabola is a vertical line passing through it

∴ The equation of the axis of symmetry is x = h

- The vertex of the parabola could be minimum point if the parabola

  opened upward or maximum if it opened downward

- The minimum value and the maximum value are the value of k

# Look to the attached figures for more understand

* Now lets solve the problem

∵ f(x) = x(x - 4)

∵ Point (2 + d , y) is on the graph of f(x)

- Replace each x in f(x) by 2 + d

∴ f(2 + d) = (2 + d)(2 + d - 4) ⇒ add 2 and -4

∴ f(2 + d) = (2 + d)(-2 + d)

∵ f(2 + d) = y

∴ y = (2 + d)( -2 + d)

* Multiply them to simplify

∴ y = 2(-2) + 2(d) + d(-2) + d(d) = -4 + 2d - 2d + d²

∴ y = -4 + d²

* Lets do these steps again with point (2 - d , y)

- Replace each x in f(x) by 2 - d

∴ f(2 - d) = (2 - d)(2 - d - 4) ⇒ add 2 and -4

∴ f(2 - d) = (2 - d)(-2 - d)

∵ f(2 - d) = y

∴ y = (2 - d)( -2 - d)

* Multiply them to simplify

∴ y = 2(-2) + 2(-d) - d(-2) - d(-d) = -4 - 2d + 2d + d²

∴ y = -4 + d²

- The value of y of the point (2 - d , y) = the value of y of the point on

  the graph

∵ f(2 + d) = f(2 - d)

∵ The point (2 + d , y) is on the graph of f(x)

∴ The point (2 - d , y) is on the graph of f(x)

* It is true the point (2 - d, y) is also on the graph.

* To find the relation between the line x = 2 and the graph of f(x)

  lets find the vertex of the parabola

- If f(x) = ax² + bx + c in the general form, where a, b , c are constant

 then h = -b/2a, where h is the x-coordinate of the vertex point, a is

 the coefficient of x² and b is the coefficient of x

∵ f(x) = x(x - 4) ⇒ multiply the bracket by x to put it in the general form

∴ f(x) = x² - 4x

- Find the value of a and b to find h

∵ a = 1 and b = -4

∵ h = -b/2a

∴ h = -(-4)/2(1) = 4/2 = 2

∴ The x-coordinate of the vertex point = 2

∵ The axis of symmetry of the parabola passing through the

   vertex point

∴ The equation of the axis of symmetry of the parabola is x = 2

* The line x = 2 is the axis of symmetry of the graph of f(x)

Step-by-step explanation:

Did they define mechanical pencils using the variable m?

A is at -8 and C i5 at 5

-8 to 0 is 8 units and 0 to 5 is 5 units.

8 +5 = 13

AC is 13 units long.

For this case, we have that by definition, the distance between two points any A and B will be the absolute value of the subtraction of their coordinates in the order that is preferred. (the distances can not be negative)

So:

We find the distance from A to a point x located at 0. ENtonces:

[tex]| -8-0 | = | -8 | = 8[/tex]

Now we add the distance from x to C. From point x (located at zero) to point C there are 5 spaces, then:

Answer:

401 people per square mile

Step-by-step explanation:

First find the number of people per square mile in Detroit by dividing people by square miles:

672,800/142.9 = 4708.18754374

Then do the same for Grand Rapids:

195,100/45.3 = 4306.84326711

Subtract:

4708.2-4306.8 = 401.4

Round to the ones place:

401

The number of more people per square mile living in Detroit compared to Grand Rapids is approximately 400.45 people per square mile.

To find the number of more people per square mile living in Detroit versus Grand Rapids, we need to find the population density for each city. Population density is calculated by dividing the population by the area. Let's do the calculations:

Detroit population density = Detroit population / Detroit area = 672,800 / 142.9 = 4,706.42 people per square mile

Grand Rapids population density = Grand Rapids population / Grand Rapids area = 195,100 / 45.3 = 4,305.97 people per square mile

To find the difference in the number of people per square mile, we subtract the population density of Grand Rapids from the population density of Detroit. Therefore, the number of more people per square mile living in Detroit compared to Grand Rapids is approximately 400.45 people per square mile.

Answer:

44%

Step-by-step explanation:

If p represents the number of portions and q represents the quantity in each portion, then the original amount needed was p·q.

After p is increased by 20%, its number is ...

p + 0.20·p = 1.20·p

After q is increased by 20%, its amount is ...

q + 0.20 ·q = 1.20·q

Then the new amount the parents must buy is ...

(1.20p)(1.20q) = 1.20²·pq = 1.44pq

This amount is ...

(1 + 44/100)·pq = pq + 44%·pq

It is 44% more than the original planned purchase.

Answer:

  2. area = 504 cm^2

  3. x = 30°

Step-by-step explanation:

2. The figure can be divided across the middle into a rectangular bottom part and a triangular top part. The triangle will have a base length of 21 cm and a height of 32 -16 = 16 cm. Its area is ...

  triangle area = (1/2)bh = (1/2)(21 cm)(16 cm) = 168 cm^2

The area of the rectangle is the product of its base (21 cm) and height (16 cm). Its area is ...

  rectangle area = bh = (21 cm)(16 cm) = 336 cm^2

Then the total area of the figure is the sum of the areas of its parts:

  total area = triangle area + rectangle area

  = (168 cm^2) + (336 cm^2) = 504 cm^2

A plane figure has no volume. The volume is zero.

What is probability?

It's a field of mathematics that studies the probability of a random event occurring. From 0 to 1, the value is expressed.

The probability of being dealt a flush:

For a suit there are 4 choices and 13C₅ choices for a card in that suit

Probability of flush = 4.( 13C₅)/52C₅

Probability of flush = 0.0019

The probability of being dealt one pair:

There are 13 possible values of a, 4C₂ choice for suit of a, 12C₃ value for b, c, d and 4 choices each for choosing the suit of b, c, d.

P(one pair) = (13.4C₂.12C₃.4.4.4)/52C₅

P(one pair) = 0.4225

The probability of being dealt two pairs:

There are 13C₂ possibility for the value of a and b, 4C₂ choices for suits of both a and b and 44 possibilities for c from the remaining cards.

P(2 pairs) = (13C₂.4C₂.4C₂.44)/(52C₅) = 0.475

The probability of being dealt three of a kind:

There are 13 possibilities for the value of a and 4C₃ choices for the suits of a, 12C₂ possibilities for both b and c and 4 choices of suits for both b and c.

P( three of a kind) = (13.4C₃.12C₂.4.4)/52C₅ = 0.211

The probability of being dealt four of a kind:

There are 13 possibilities of a and 4C₄ values for the suit of a and 48 choices of b from the remaining cards.

P(four of a kind) = (13.4C₄.48)/52C₅ = 0.00024

Final answer:

To find the total fraction of the lawn mowed by Melvin before his first break, one would add the additional 3/10 to the already mowed fraction represented by the shaded model.

Explanation:

The student's question is about calculating the fraction of the lawn that will be mowed by Melvin before he takes his first break. Initially, the question does not specify what fraction of the lawn is already mowed, but indicates that Melvin will mow an additional 3/10 of the lawn. Assuming that the shaded model represents the fraction already mowed (let's say x), the total fraction mowed before Melvin's first break would be x + 3/10. Without the specific value of the initially mowed fraction, we cannot provide the exact answer; however, generally, the operation would involve adding the given fraction to Melvin's progress before he mows the additional 3/10.

Answer:

The vertices are (3 , -5) , (-5 , -5)

The foci are (4 , -5) , (-6 , -5)

Step-by-step explanation:

* Lets study the equation of the hyperbola

- The standard form of the equation of a hyperbola with  

  center (h , k) and transverse axis parallel to the x-axis is

  (x - h)²/a² - (y - k)²/b² = 1

- The length of the transverse axis is 2 a

- The coordinates of the vertices are  (h  ±  a  ,  k)

- The coordinates of the foci are (h ± c , k), where c² = a² + b²

- The distance between the foci is  2c

* Now lets solve the problem

- The equation of the hyperbola is (x + 1)²/16 - (y + 5)²/9 = 1

* From the equation

# a² = 16 ⇒ a = ± 4

# b² = 9 ⇒ b = ± 3

# h = -1

# k = -5

∵ The vertices are (h + a , k) , (h - a , k)

∴ The vertices are (-1 + 4 , -5) , (-1 - 4 , -5)

* The vertices are (3 , -5) , (-5 , -5)

∵ c² = a² + b²

∴ c² = 16 + 9 = 25

∴ c = ± 5

∵ The foci are (h ± c , k)

∴ The foci are (-1 + 5 , -5) , (-1 - 5 , -5)

* The foci are (4 , -5) , (-6 , -5)

Answer:

Vertices: (3,-5) (-5,-5)

Foci: (-6,-5) (4,-5)

Step-by-step explanation:

(x+1)^2/16-(y+5)^2/9 =1

formula: (x-h)^2/a^2 -(y-k)^2/b^2=1

in this case...

a^2=16      b^2=9

h=-1 k=-5

a=4           b=3

v=(h+/-a,k)

v1=(-1+4,-5)=

v1=(3,-5)

v2=(-1-4, -5) =

v2=(-5,-5)

Foci=(h+/-c,k)

F1=(h-c,k)

=(-1-5,-5)

f1=(-6,-5)

F2=(h+c,k)

=(-1+5, -5)

F2=(4,-5)
