WANR - 22%
WCLM - 24%
WWCN - 41%
WKOD - 13%

The ratio of WANR to WCLM is 22:24  OR 11:12
Ratio of WANR to the whole is 22:100 OR 11:50
Ratio of WCLM to the whole is 24:100 OR 12:50

Answer: 11/12 is the ratio to express  the number of people who preferred WANR to those who preferred WCLM.

Step-by-step explanation:

Let the total number of people= x

So, According to the given diagram,

The number of people who preferred WANR = 22% of x

While, The number of people who preferred WCLM = 24% of x

Therefore, The number of people who preferred WANR/The number of people who preferred WCLM = 22% of x / 24% of x

= \frac{22/100\times x}{24/100\times x} = \frac{22}{24} =\frac{11}{12}

Which is the required answer.

Answer:

<u>For the graph in the top-left corner, the ?? = 0.25</u>

This can be found using a simple slope equation:

m = (y2-y1)/(x2-x1)

m = slope

You take two coordinates, in this case (8, 2) and (4, 1), label one as #1 and the other as #2, and plug in the values so:

slope = (2-1)/(8-4)

slope = 1/4 or 0.25

The equation of a line is y = mx + b and if you were to place 0.25, or 1/4, in place of m (the slope) and 1 in the place of x since it is the x value, and multiply, you would end up with 0.25.

This also gives you the answer to your next two questions.

<u>The one in the top-right corner is $0.25 per pencil.</u>

<u>The answer to the question just below it is y = 0.25x.</u>

b in the equation would equal 0 since b is the y-intercept (where the line crosses the y-axis)

As for the last one, you simply have to multiply 30 by each number in the left column since you already know 30 miles are travelled in 1 hour, giving you your rate or the equation of the line, y=x.

<u>The missing values of the table are as follows:</u>

<u>0, 60, 150, 240, 330, 1470</u>

Finally, the last box:

<u>Miles = 30 * hours</u>

<u>y = 30x</u>

Of two consecutive integers, four times the smaller is 30 more than three times the larger. Find both integers,
WITCHER [35]

Answer:

33 and 34

Step-by-step explanation:

Let the integers be x and x+1 respectively.

4x = 3(x+1) + 30

x = 33

therefore, the integers are 33 and 34

This is a question on forming and solving algebraic equations. If you wish to venture further into it/understand this topic better, you may want to follow my Instagram account (learntionary), where I post some of my own notes on certain topics and also some tips that may be useful to you :)

If ORBIT is coded BEOVG, then how is PLANET coded? /
arlik [135]

Answer:

1. CYNARG

Step-by-step explanation:

This a example of Caesar's Cipher, in which each letter in the original word leads to a ciphered letter according to the following equation:

C = (P + o) \text{mod} 26

In which C is the index of the Ciphered letter in the alphabet, P is the index of the original letter and o is the offset.

Finding the offset:

O is coded B

O is the 15th letter in the alphabet, so P = 15.

B is the 2nd letter in the alphabet, so C = 2

C = (P + o) \text{mod} 26

2 = (15 + o) \text{mod} 26

|o = |2-15| \text{mod} 26

o = 13

So

C = (P + 13) \text{mod} 26

PLANET:

P

P is the 16th letter in the alphabet.

C = (16 + 13) \text{mod} 26 = 3

So P is coded C.

L

L is the 12th letter in the alphabet:

C = (12 + 13) \text{mod} 26 = 25

L is coded Y(25th letter in the alphabet)

A

A is the 1st letter in the alphabet

C = (1 + 13) \text{mod} 26 = 14

A is coded N

N

N is the 14th letter in the alphabet

C = (14 + 13) \text{mod} 26 = 1

N is coded A

E

E is the 5th letter in the alphabet

C = (5 + 13) \text{mod} 26 = 18

E is coded R

So the correct answer is:

Write the equation of a line that is perpendicular to y=0.3x+6 and that passes through the point (3,-8)
Harman [31]

<u>First, find the perpendicular slope</u>

y = 0.3x + 6   ⇒ m = 0.3  = \frac{3}{10}

perpendicular slope =  -\frac{10}{3}

<u>Next, input</u> the point (x₁, y₁) and slope (m) into the Point-Slope formula

  y - y₁ = m(x - x₁)

y - (-8) = -\frac{10}{3}(x - 3)

 y + 8 = -\frac{10}{3}x + 10

      y = -\frac{10}{3} + 2
