Answer: 6

Step-by-step explanation:

The the scale factor being used to enlarge the photo is 6. Therefore, option B is the correct answer.

A scale factor is defined as the ratio between the scale of a given original object and a new object, which is its representation but of a different size (bigger or smaller).

The basic formula to find the scale factor of a figure is expressed as,

Scale factor = Dimensions of the new shape ÷ Dimensions of the original shape.

Given that, the photo below is being enlarged to form a 24- by 30-inch print.

In the figure, the dimensions are 4 inches and 5 inches.

Scale factor = 24/4 = 6

and 30/5 = 6

Therefore, option B is the correct answer.

Answer: REMEMBER (X, Y)

x(4 1/4, 0)

y(0, -5 2)

Step-by-step explanation:

Find the x-intercept

To find x intercept subtract y equals 0

4 x - 3 × 0 = 17

Any equation multiplied by  0 equals 0

4x - 0 = 17

When adding or subtracting zero quality does not change

4x = 17

Divide both sides of the equation by 4

x = 17/4

Solution

X = 17/4

Alternate form

X = 4 1 / 4, x = 4.25

Find y-intercept

To find y intercepts subtract x equals 0

4 × 0 - 3y = 17

Solve the equation for y

Y = -17 / 3

Solution

y = -17 / 3

Alternate form

y = -5 2 / 3, y = -5.6

Answer:

The concession stands needs to sell 14 or more bags.

Step-by-step explanation:

Given that:

Cost per bag of popcorn = $2.50

Number of bags already sold = 30

Cost of 30 bags = 30*2.50 = $75

Bags needs to be sold to make $110 = x

2.50x + 75 ≥ 110

2.50x ≥ 110-75

2.50x ≥ 35

Dividing both sides by 2.50

[tex]\frac{2.50x}{2.50}\geq \frac{35}{2.50}\\x\geq 14[/tex]

Hence,

The concession stands needs to sell 14 or more bags.

Answer:

-12

Step-by-step explanation:

Step1: Add 3 to both sides of the equation

2x -3 = 5x +6

    +3         +3 = 9

Step2: subtract 5x from both sides of the equation

2x = 5x +9

-5    -5

Step3: divide both sides of the equation by the same term

-3x(/ -3) = 9(/-3)    

Step4: multiply -3 with 2

-3x2= -6

Step4: subtract -6 with 3

-6 - 3= -9

Step5: add the -9 to -3

-9 + -3 = -12

Explanation:

The quadrilateral is a parallelogram if the midpoints of its diagonals are the same point. That is, if ...

  (N +Q)/2 = (P +R)/2

Multiplying by 2, we can simplify the test to ...

  N +Q = P +R

  (5, 1) +(6, 9) = (2, 7) +(9, 3)

  (5+6, 1+9) = (2+9, 7+3)

  (11, 10) = (11, 10) . . . . . . . true ∴ NPQR is a parallelogram

Answer:

Length of spaceship in movie = 528

Step-by-step explanation:

Given that:

Drawing ratio of spaceship = 1 : 24

It means that 1 inch on drawing equals 24 inches in movie

Drawing of spaceship = 22 inches

Length of spaceship in movie = x

As the relationship is proportional,

1 : 24 :: 22 : x

Product of mean = Product of extreme

24*22 = x

x = 528

Hence,

Length of spaceship in movie = 528
