Answer:

75

Step-by-step explanation:

Number of necklace= k × amount of time spent

6= k × 2/5

K = 6÷2/5

K= 6×5/2

K= 15

Therefore the number of necklace made in 5 hours can be calculated as follows

15 = number of necklace ÷ 5

Number of necklace = 15 ×5

Number of necklace = 75

75

Answer:

34 edges

Step-by-step explanation:

Euler's formula for polyhedron states

F + V - E = 2

where F is number of faces, V, number of vertices, E number of edges

Here F = 16, V = 20, thus

16 + 20 - E = 2, that is

36 - E = 2 ( subtract 36 from both sides )

- E = - 34 ( multiply both sides by - 1 )

E = 34

Answer:

-20

Step-by-step explanation:

y = -3x+1

if the input is 7, it means x=7 so substitute in the equation

y= -3*7+1 = -21+1= -20 which is the output

6x + 18y = 18. Let us take x = 0

6(0) + 18y = 18

0 + 18y = 18

18y = 18

y = 18/18

y = 1

(0, 1) [x = 0, y = 1]

6x + 18y = 18. Let us take y = 0

6x + 18(0) = 18

6x + 0 = 18

6x = 18

x = 18/6

x = 3

(3, 0) [x = 3, y =0]

Infinite solutions can be found for x and y

Answer:

The graph of a quadratic function is a curve called a parabola which makes a quadratic function unique.

Step-by-step explanation:

Parabolas may open upward or downward and vary in "width" or "steepness", but they all have the same basic "U" shape which makes it easy to identify.

Hope it helps.

Answer:

Step-by-step explanation:

Maybe that can be solve in so

-maybe diferent ways like graphicly, quadratic equation, factoring, form a perfect square...

-maybe because it has real, imaginary roots, or equal roots

Answer:

ab+ac=a(b+c)

a is a common factor

find the greatest common factor

12x+18

12x=2*2*3*x

18=2*3*3

GCF=2*3=6

12x+18=

6(2x)+6(3)=

6(2x+3)

Answer:

No it is not a right triangle.

Step-by-step explanation:

We calculate the squares of the two littlest sides and add them :

6² + 8² = 36 + 64 = 100

We now calculate the square of the biggest side :

12² = 144

They are not equal, and thus, the triangle is not a right triangle.

Hope this helped! If so, plz mark brainliest.

Answer:

No, Because 6^2 + 8^2 = 12^2

Answer:

The CD player costs $296 and the Nike sneaker costs $148.

Step-by-step explanation:

From the information given, you know that a CD player and a Nike sneaker together cost $ 444, which can be expressed as:

x+y=444, where

x is the cost of the CD player

y is the cost of the Nike sneaker

Also, you know that the price of the CD player is double the price of the sneaker, which can be expressed as:

x=2y

You can replace this formula x=2y in the first one and solve for y:

2y+y=444

3y=444

y=444/3

y=148

Finally, you can replace the value of y in x=2y to find the value of x:

x=2(148)

x=296

According to this, the answer is that the CD player costs $296 and the Nike sneaker costs $148.

Answer:

Well, you look at each individual place value.

1.679 and 1.697

Compare 1 to 1. They are the same. Move on.

Compare 0.6 to 0.6. They are the same. Move on

Compare 0.07 and 0.09. They are not the same. 0.07 is less than 0.09

Therefore 1.679 < 1.697

System of Linear Equations entered :

  [1]    4x - 2y = 2

  [2]    3x - 2y = -19

Graphic Representation of the Equations :

   -2y + 4x = 2        -2y + 3x = -19  

Solve by Substitution :

// Solve equation [2] for the variable  x

 [2]    3x = 2y - 19

 [2]    x = 2y/3 - 19/3

// Plug this in for variable  x  in equation [1]

  [1]    4•(2y/3-19/3) - 2y = 2

  [1]    2y/3 = 82/3

  [1]    2y = 82

// Solve equation [1] for the variable  y

  [1]    2y = 82

  [1]    y = 41

// By now we know this much :

   x = 2y/3-19/3

   y = 41

// Use the  y  value to solve for  x

   x = (2/3)(41)-19/3 = 21

Solution :

{x,y} = {21,41}

Answer: {x,y}={21,41}

Answer:

Option B

Step-by-step explanation:

Well, now that I found out the prices per ounce, it has to be option B. Here is my reasoning:

Option A, when you do 2.98÷15.5, you get 0.19225...

Option B, is a different story. When you do the same process, it amazingly comes out to 0.1785...(this means that Option B is 0.2 cents (rounded) cheaper per unit, then Option A.

So its option B

Your welcome.

Answer:

You should use 0.6 cups of pineapple juice if you only have 1 cup of orange juice.

Step-by-step explanation:

With the information provided about the recipe, you can use a rule of three to find the cups of pineapple you should use if you only have 1 cup of orange juice given that the recipe calls for 30 cups of orange juice and 18 cups of pineapple juice:

30 cups of orange juice → 18 cups of pineapple juice

 1 cup of orange juice    →                    x

x=(1*18)/30=0.6 cups of pineapple juice

According to this, the answer is that you should use 0.6 cups of pineapple juice if you only have 1 cup of orange juice.

Answer:

Step-by-step explanation:

put the y intercept at 4. then go down 1 and right three, down one, then right three. go back to the y intercept and then go up one and left three, up one and left three

to answer this you should plot a point at (0,4). That is the y intercept as you can see on the equation +4 is at the end. Since the slope is -1/3, go 1 unit left and 3 up from the y intercept. those are your two points and draw a straight line though.

Answer:

3.61 miles

Step-by-step explanation:

Given that:

Length of track = 5/6 of a mile

Number times Mary was able to run around the track = 4 1/3 times

Total miles ran by Mary :

(Equivalent mile of the track * number of times Mary ran around the track)

5/6 of a mile * 4 1/3 times

5/6 * 13/3

= 65 / 18

= 3.611111 miles

Hence, total Number of miles ran by Mary is 3.61 miles

Answer:

this is a positive slope
