Step-by-step explanation:

Answer:

p = 5k - 40

Step-by-step explanation:

Since we're finding the profit (p), it's not the last answer choice because it's finding kids (k).

Because we have to take out from her profit whatever Katie spent, we would have -40.

Because she'd charging $5 per kid, or $5 per k, we would have 5k.

So now we know the profit is whatever she makes, then minus whatever she spent. So:

p = 5k (what she makes) - 40 (what she spent)

p = 5k - 40

Answer:

O p = 40k + 5

Step-by-step explanation:

Katie is raising money to buy  a dog. She starts a  neighborhood babysitting service.

If a line parallel to one side of a triangle intersects the other two sides of the triangle, then the line divides these two sides proportionally.

Answer:  h= 5/g−3/2

Step-by-step explanation:

h=  5 over g minus   3 over 2

Answer:

[tex]h\neq -3/2[/tex]

Step-by-step explanation:

Divide both sides by h+3/2;

g(h+3/2)/h+3/2=5/h+3/2

simplify

g=10/2h+3; h[tex]\neq[/tex]-3/2

Look at the picture. :)

105 can be expected to prefer chocolate milk

Let the expected students be x

Calculate the total students = 15+12+6+2 = 35

The expected students prefer milk is

15/35 = x/245

245*15=35x

3675 = 35x

x = 3675 / 35

x = 105

Hence 105 students are expected to prefer chocolate milk .

Answer:

x = -1, y = -1.

Step-by-step explanation:

-3x +y = 2

7x – 8y = 1

We can use the  elimination method to solve these:

Multiply the first equation by 8:

-24x + 8y = 16

Now add this to the second equation:

-17x -8y + 8y = 17

-17x = 17

x = -1.

Plug x = -1 into the first equation:

-3(-1) + y = 2

3 + y = 2

y = -1.

Step-by-step explanation:

A diameter spans from one end of (in this case, a circle) to the direct opposite end, going through the center-point. The radius, on the other hand, is half of a diameter, and spans only from the center-point to a point on the circle.

In this case:

1) Diameter = 18 km (given)

  Radius = 18/2 = 9 km

2) Diameter = 1 x 2 = 2 m

   Radius = 1 m (given)

3) Diameter = 17 x 2 = 34 cm

   Radius = 17 cm (given)

4) Diameter = 50 mm (given)

  Radius = 50/2 = 25 mm

John has a swimming pool, in which the center of the pool to the edge is 3 meters. What is the diameter? Simply multiply 3 with 2:

3 x 2 = 6 meters

6 meters is the diameter.

Answer:

Boys= 12

Girls= 6

Step-by-step explanation:

Let no: of girls be 'x'

No: of boys= 2x

boys after= 2x-6

girls after = x+6

according to the question,

2(2x-6)=x+6

4x-12=x+6

3x=18

x=6

No: of girls at first= 6

No: of boys at first=2*6=12

Answer:

Step-by-step explanation:

Rate of decrease = 3% = 0.03

Number of decreased employees = Current number of employees * rate of decrease * number of years

= 810 * 0.03 * 16

= 388.8

= 389

Number of employees = 810 - 389 = 421

recall :

nCr = n! ÷ (n - r)!r!

Using calculator :

12C4 = 495

43C3 = 12341

12C4 * 43C3

Answer:

x=5, y=1

Step-by-step explanation:

Isolate x for 5x-3y=22

5x-3y=22

Add 3y to both sides

5x-3y+3y=22+3y

Simplify

5x=22+3y

Divide both sides by 5

5x/5=22/5+3y/5

Simplify

x=22+3y/5

Substitute  x=22+3y/5

10*22+3y/5-4y=46

Simplify 10*22+3y/5-4y

10*22+3y/5=2(3y+22)

=2(3y+22)-4y

Expand 2(3y+22)

=6y+44-4y

Simplify 6y+44-4y

=2y+44

Isolate y for 2y+44=46

2y+44=46

Subtract 44 from both sides:

2y+44-44=46-44

Simplify

2y=2

Divide both sides by 2;

2y/2=2/2

Simplify;

y=1

For x=22+3*1/5 substitute y=1

y=22+3*1/5

22+3*1=25

=25/5

Divide the numbers;25/5=5

=5

x=5

The solutions to the system of equations are;

x=5, y=1

Answer:

$ 20,189.65

Step-by-step explanation:

Jake's parents want $100,000 at the end of 40 years. They put their money in an account that yields 4% per year compounded continuously. How much money should jakes parents deposit?

From the above question, we are to find the Principal. The formula for Principal compounded continuously =

P = A / e^rt

Where:

A = Amount after time t = $100,000

r = Interest rate = 4%

t = Time in years = 40 years

First, convert R percent to r a decimal

r = R/100

r = 4%/100

r = 0.04 per year,

Then, solve our equation for P

P = A / e^rt

P = 100,000.00 / e ^(0.04×40)

P = $ 20,189.65

Therefore, the amount Jake's parents should invest = $ 20,189.65

Answer:

A = 20 + 2p

Answer:

x ≈ 261 ft

Step-by-step explanation:

Using the sine ratio in the right triangle

sin50° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{200}{x}[/tex] ( multiply both sides by x )

x × sin50° = 200 ( divide both sides by sin50° )

x = [tex]\frac{200}{sin50}[/tex] ≈ 261 ft ( to the nearest foot )

x ≈ 261 ft

that is the answer
