Answer:

8% increase

Step-by-step explanation:

The length after the increase:

30 x 1.1 = 33cm

The width after the increase:

20 x 1.05 = 21cm

New perimeter:

2(33 + 21) = 108 cm^2

Old perimeter:

2(30 + 20) = 100 cm^2

Percentage increase of area:

108 / 100 = 1.08 = 8% increase

Answer: A. [tex]\dfrac{3}{30}=\dfrac{x}{12}[/tex]

Step-by-step explanation:

According to the recipe,

For 2 batches, 3 cups of flour required.

One batch has 15 mix rolls

Then 2 batches will have 2 (15) = 30 rolls

Each person gets one roll, so 3 cups of flour is required for 30 people.

The quanity of flour is proportional to the number of people.

Let x be the quantity of flour required for 12 people.

By proportion,

[tex]\dfrac{\text{Quantity of flour}}{\text{Quanity of person}}=\dfrac{3}{30}=\dfrac{x}{12}[/tex]

Required proportion: [tex]\dfrac{3}{30}=\dfrac{x}{12}[/tex]

The correct option is A. [tex]\dfrac{3}{30}=\dfrac{x}{12}[/tex]

Answer:

21/8

Step-by-step explanation:

KCF or keep change flip. keep 7/8. turn divide into multiply, then flip 1/3 to 3/1. 21/8 is what you get. Hope this helped!

Answer:

21/8

Step-by-step explanation:

Dividing by a fraction is like multiplying with the inverse:

So (7/8) / (1/3)

is the same as

(7/8) * (3/1) = (7/8) * 3 = 21/8

21/8 cannot be simplified, unless you find 2  5/8 simpler

Answer:

Step-by-step explanation:

One point can be the y-intercept. We can see that the y-intercept is (0,-3). -3 is the value of y when x = 0. The next point can be when x = 2. If we plug that in the equation, we get the point (2,-6).

Plotting these two points will graph the equation.

The graph is given below.

Some of the coordinates on the graph are (0, -3, (1, -4.5), and (2, -6).

The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.

The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.

We have,

y = (-3/2)x - 3

The coordinates from the given equation are:

When x = 0,

y = - 3

(0, -3)

When x = 1,

y = -3/2  - 3 = (-3 - 6)/2 = -9/2 = -4.5

(1, -4.5)

When x = 2,

y = -3 - 3 = -6

(2, -6)

Now,

The graph of the equation is given below.

Thus,

The graph is given below.

Answer:

5.265748

Step-by-step explanation:

i did a cm to feet calcu-lator

have good day

The correct answer is 4 feet 17 inches is 160.5 c.m.

The process to convert cm to feet is simple. 1 cm. is equal to 0.025 feet. So you must multiple the unit by 0.025.

Given:

1 feet = 38.48 cm.

1 cm. = 0.025 feet.

160.5 cm = (0.025/1) * 160.5

160.5 cm = 4.1709 feet  

4.1709 feet  

4.1709 feet  = 4 feet + 1709 inches.

We can 4.1709 feet which is equal to 4 feet 17 inches.

Therefore, 160.5 cm is equal to  4 feet 17 inches.

Answer:

15 people voted yes and 3 people voted no.

Step-by-step explanation:

Given that:

Ratio of yes to no = 5 : 1

Total number of board members who voted = 18

Let,

x be the number of times.

5x+x = 18

6x = 18

Dividing both sides by 6

[tex]\frac{6x}{6}=\frac{18}{6}\\x=3[/tex]

People who voted yes = 5(3) = 15

People who voted no = 3

Hence,

15 people voted yes and 3 people voted no.

Area of rectangle = [tex]\mathbf{x^2-4x}[/tex]

Perimeter of rectangle = [tex]\mathbf{4x-8}[/tex]

Step-by-step explanation:

We are given:

Length of rectangle = x

Width of rectangle = x-4

We are not given if we want to find area of rectangle or perimeter of rectangle.

So, I will be finding both

Area of rectangle

The formula used is: [tex]Area\: of\: rectangle=Length \times Width[/tex]

Putting values and finding area

[tex]Area\: of\: rectangle=Length \times Width\\Area\: of\: rectangle=x \times (x-4)\\Area\: of\: rectangle=x^2-4x[/tex]

So, we get area of rectangle = [tex]\mathbf{x^2-4x}[/tex]

Perimeter of rectangle

The formula used is: [tex]Perimeter \: of\: rectangle=2(Length+ Width)[/tex]

Putting values and finding perimeter

[tex]Perimeter \: of\: rectangle=2(Length+ Width)\\Perimeter \: of\: rectangle=2(x+ x-4)\\Perimeter \: of\: rectangle=2(2x-4)\\Perimeter \: of\: rectangle=4x-8[/tex]

So, we get perimeter of rectangle = [tex]\mathbf{4x-8}[/tex]

Answer:

   -135/14

Step-by-step explanation:

There are an infinite number of rational numbers between any pair of numbers you name. These two number have the decimal values ...

  -67/7 = -9 4/7 = -9.571428... (repeating)

  -78/8 = -9 3/4 = -9.75

So, numbers like -9.6 = -48/5, or -9.7 = -97/10 are rational numbers that lie in the range you specified.

If you like, you can convert these numbers to ones with a common denominator (56).

 -67/7 = -536/56

 -78/8 = -546/56

These limits suggest several possible rational numbers with 56 as a denominator: -540/56 = -135/14, for example.

Answer:

24+15k=

Step-by-step explanation:

First we multiply the 6 to the numbers in the parentheses, so 4x6=24, and 2x6=12, making the expression look like this: 24+12k+3k=

Then we combine like terms, which would be the number that are attached to 'k'. So that makes the expression look like this: 24+15k=

Answer:

Head bands: 18.58 inches of fabric

Wrist bands : 8.51 inches of fabric

Step-by-step explanation:

Jillian is making accessories for the soccer team.

For head bands

She uses 761.78 inches of fabric on headbands for 39 players and 2 coaches.

The total number of people = 39 player + 2 coaches = 41 people

Hence:

41 persons = 761.78 inches of fabric

1 person = x

Cross Multiply

41 × x = 761.78 × 1

x = 761.78/48

x = 18.58 inches

For wristbands

She also uses 331.89 inches of fabric on wristbands for just the players.

Number of players = 39 players

Hence:

39 players = 331.89 inches

1 players = x inches

Cross Multiply

39 × x = 1 × 331.89 inches

x = 331.89 inches/39

x = 8.51 inches

Therefore:

18.58 inches of fabric was used for head bands and 8.51 inches of fabrics was used for wristbands.

Step-by-step explanation:

We have Angle ZWD = Angle DWN.
