John makes and sells cookies. He made a profit of 58 dollars last week. The next week he decided to donate cookies to a local charity. His profit (earnings) for that week is represented by -27 since he didn't earn any money. Write a subtraction and addition expression to represent John's profit for the two weeks combined.

14 mph

Step-by-step explanation:

13.636364

is what you get by doing

100/15 then you get 6.6666......7

after that you multiply that by 3600 because thats how many seconds in that hour.

Then you get 24000 and transfer it to miles and get 13.636364 and you round it and get 14mph

The height of the flagpole is: 12 ft.

A theorem attributed to Pythagoras that the square on the hypotenuse of a right-angled triangle is equal in area to the sum of the squares on the other two sides.

Let the height of the flagpole be: x ft.

Now, we can model this problem with the help of a right angled triangle such that the hypotenuse of the triangle is: 20 feet

and one of the leg of the right triangle is: 16 feet

Now, in order to find the other leg i.e. x we need to use the Pythagorean Theorem.

[tex]20^2=x^2+16^2\\\\\\400=x^2+256\\\\\\x^2=400-256\\\\\\x^2=144\\\\\\x=\pm12[/tex]

i.e.

But the height can't be negative.

Hence, we get: x=12

a) 2x² - 32 = 2(x-4)(x+4)

e) 3x² - 75 y² = 3(x-5y)(x+5y)

i) (x+5)² - 16 = (x+1)(x+9)

j) (x-4)² - 9 = (x-7)(x-1)

m) (3x+5)² - x² = (2x+5)(4x+5)

Step-by-step explanation:

Basically first you expand the expression into terms and then you refactor again.

Answer:

25pi

Step-by-step explanation:

To solve this, create a right triangle between the two points. We know the distance of one leg is 6, and the distance of the other leg is 8. Use the Pythagorean theorem to solve for the diameter. You substitute 6 and 8 into the values of A and B. Once you get this, you get (6^2)+(8^2)=c^2. Once you further simplify this, you get 36 + 64 = c^2, which is 100 = c^2. Take the square roots of both sides to get the diameter as 10. Divide the diameter by 2 to get the radius. Square the radius and multiply it by pi to get the area. Doing this will get the result of 25 pi.

Hey there!

The x-intercept is (6,0) meaning that if no children attend, 6 adults will attend.

The y-intercept is (0,14) meaning that if no adults attend, 14 children will attend.

Let me know if this helps :)

The x-intercept is (6,0) and y-intercept is (0,14).

x-intercept for "any curve is the value of x-coordinate at the point where the graph cuts the x-axis".

What is y-intercept?

y-intercept  for "any any curve is the value of y-coordinate at the point where the graph cuts the y-axis".

According to the question,

3.5x + 1.5y =21

Let 'x' is the number of adults and 'y' is the number of children.

To find  x-intercept put y=0.

3.5x + 1.5(0) = 21

             3.5x = 21

                  x = 21/3.5 =6.

To find y-intercept put x=0

3.5(0) + 1.5(y) = 21  

                  y = 21/1.5 = 14.

x-intercept (6,0) if no children attend the play then 6 adult attend the play. y - intercept (0,14) if no adult attend the play then 14 children attend the play.

Hence, The x-intercept is (6,0) and y-intercept is (0,14).

101 and 104 i think is the most easy answer

Answer:

101, 103

Step-by-step explanation:

Say n is the first odd integer. The sum of n and its consecutive integer can be written as n + (n + 2). Doing some simple algebra:

n + (n+2) =204

2n + 2 = 204

2n = 202

n = 101

n is 101, and its consecutive integer, (n+2), is 103.

Answer:

A because 63/4 is 15.75

Answer:

1. rate = 171.6 feet/second

2. 1716 feet

Step-by-step explanation:

1. To convert from miles per hour to feet per second,

1 mile = 5280 feet

  117 miles = 617760 feet

  1 hour = 3600 seconds

Thus the rate in feet per second will be;

    = [tex]\frac{617760}{3600}[/tex]

    =  171.6 feet/second

2. In 10 second of free fall,

       speed = [tex]\frac{distance}{time}[/tex]

distance = speed x time

              = 171.6 feet/second x 10 second

              = 1716 feet

The parachutist would fall 1716 feet in 10 seconds of free fall.

Answer:

so whats the question

Step-by-step explanation:

Answer: OPTION B

Step-by-step explanation:

First of all, you need to know the concept of imaginary number or i.

i (imaginary number)= √-1 ⇔ In real number world, √-1 will be undefined,  

                                               and thus this is called imaginary number

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

√-2=√2 × √-1

√-2=√2× √-1

√-2=√2 × i

√-2= √2 i

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

√-18=√9 × √2 × √-1

√-18= √9 × √2 × √-1

√-18= 3 × √2 × i

√-18= 3√2 i

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

Addition in radical numbers is as usual as normal number. HOWEVER, only numbers that has the same radical (i.e 2√3 and 7√3) can combine.

 √-2 + √-18

=√2 i + 3√2 i

=4√2 i

Answer:

The number of cheese pizza sold is 200 cheese pizzas

The number of sausage pizza sold is 80 sausage pizzas

The number of pepperoni pizza sold is 120 pepperoni pizzas

Step-by-step explanation:

The price at which the pepperoni  pizza was sold is $14

The price at which the sausage pizza was sold is $11

price at which the cheese pizza was sold is $10

The total number of pizzas sold = 400

The total amount made = $4560

The number of cheese pizza sold = 80 + the number of pepperoni pizzas

Let the number of cheese pizza sold = C

The number of sausage pizza sold = S

The number of pepperoni pizza sold = P

We have;

C + S + P = 400..........................(1)

C = 80 + P...................................(2)

10·C + 11·S + 14·P = $4560.......(3)

Substituting the value for C from equation (2) in equation (1), we get;

C + S + P = 400 = 80 + P + S + P = 400

2·P + S = 400 - 80 = 320

∴ S = 320 - 2·P..........................(4)

Substituting the value for C from equation (2) and the value for S from equation (4) into equation (3), we get;

10·C + 11·S + 14·P = $4560

10·(80 + P) + 11·(320 - 2·P) + 14·P = 4560

800 + 10·P + 3,520 - 22·P + 14·P = 4560

4,320 + 2·P =  4560

2·P =  4560 - 4,320 = 240

P = 240/2 = 120

P = 120

C = 80 + P = 80 + 120 = 200

C = 200

S = 320 - 2·P = 320 - 2×120 = 320 - 240 = 80

S = 80

Therefore;

The number of cheese pizza sold = C = 200

The number of sausage pizza sold = S = 80

The number of pepperoni pizza sold = P = 120.

[tex]x=1[/tex]

Step-by-step explanation:

So we have the equation:

[tex]4(-x+4)=12[/tex]

First, divide both sides by 4. The left side will cancel. The right will reduce to 3:

[tex](4(-x+4))/4=(12)/4\\-x+4=3[/tex]

Subtract 4 from both sides. The left cancels:

[tex]-x=-1[/tex]

Divide both sides by -1:

[tex]x=1[/tex]

So, the value of x is 1.

And we're done!

Answer:

x = 1

Step-by-step explanation:

4(-x + 4)= 12

Step 1 : Distribute

-4x + 16 = 12

Subtract 16 from both sides

-4x = -4

Divide

[tex]\frac{-4x}{-4}[/tex] = [tex]\frac{-4}{-4}[/tex]

x = 1

Greetings from Brasil....

Let us call X the equal distances GH = HI = IJ

GH = X

HI = X

IJ = X

Note that HJ = HI + IJ, so

HJ = X + X

10 = 2X

X = 5

Looking at the figure we can conclude that:

GJ + JK = GK

GJ = GH + HI + IJ

GJ = 15

GJ + JK = GK

15 + JK = 24

JK = 9

Each length of the line segments GH = HI = IK and JK will be 5 and 9.

A line segment in mathematics has two different points on it that define its boundaries.

A line segment is sometimes referred to as a section of a path that joins two places.

GK = 24, HJ = 10, and GH = HI = IJ.

Then the length HI will be

HJ = HI + IJ

10 = HI + HI

2HI = 10

HI = 5

Then the length of the line segments GH, HI, and IJ will be

GH = HI = IJ = 5

The length of the JK will be

GK = GJ + JK

24 = 3GH + JK

24 = 3 * 5 + JK

JK = 24 - 15

JK = 9

Then each length of the line segments GH = HI = IK and JK will be 5 and 9.

Answer:

Assuming that m does not = 0, then the function has a non horizontal slope, so the value will increase as the position moves away from zero in either the negative or positive direction depending on whether the slope (m) is negative or positive. The furthest that the position can be from 0 is at one of the endpoints of the interval [3, 7), therefore, the maximum value of the function on the same interval must be at one of the endpoints.
