The Proportionality Constant is used to compare values that are proportional.

When two variables are proportional to each other , change in one cause the change in the other .

There are two types of proportion, Direct and Indirect.

When on increasing one variable the other increases and vice versa it is called direct proportion .

When on increasing one variable the other decreases and vice versa it is called indirect proportion .

Answer:

Then common factor is 16

Step-by-step explanation:

The factored expression is equivalent to -

8(6 + 10)

In mathematics, the greatest common divisor of two or more integers, which are not all zero, is the largest positive integer that divides each of the integers.

Given is to factor the given expression using the greatest common factor A = 48 + 80

For -

48 = 2 x 2 x 2 x 2 x 3

80 = 2 x 2 x 2 x 5

Using the greatest common factor, we can write -

48 + 80

8(6 + 10)

Therefore, the factored expression is equivalent to -

8(6 + 10)

Answer:

  11·11^4

Step-by-step explanation:

The applicable rules of exponents are ...

  (a^b)(a^c) = a^(b+c)

  a = a^1

  (a^b)/(a^c) = a^(b-c)

  a^0 = 1 . . . . for any 'a' not 0

__

The given expression is ...

  (11^8)/(11^3) = 11^(8-3) = 11^5

The offered choices are ...

  (11^7)/(11^7) = 11^(7-7) = 11^0 = 1

  11·11^4 = (11^1)(11^4) = 11^(1+4) = 11^5 . . . . matches the given expression

  (11^0)/(11^5) = 11^(0-5) = 11^-5

  11^0 = 1

Answer:

Step-by-step explanation:

Because 5 + 5 is 10, so 1/2 of 10 + 1/2 of 10 = 10

Answer:

c = 30°

d = 60°

Step-by-step explanation:

Angle ZWC is a 90° angle

Angle YWX is a 60° angle

add them together and you get 150°

180 - 150 = c = 30°

c + d + 90° = 180°

substitute

30° + d + 90° = 180°

combine like terms

120° + d = 180°

subtract 120° from both sides

d = 60°

hope this helps!!

Answer:

c is 30 and d is 60

Answer:

The most amount of dogs that you can walk in a given day is 30 dogs.

Step-by-step explanation:

You decide to charge in 30 minute intervals, and due to your schedule you can only walk 3 hours a day. Then you must know how many intervals of walks you can do in those 3 hours a day that you can walk. Being 1 hour equal to 60 minutes, then 30 minutes equals 2 intervals in 1 hour. Then you can apply the following rule of three: if in 1 hour there are 2 intervals of 30 minutes, in 3 hours how many intervals of 30 minutes are there?

[tex]amounts of intervals=\frac{3hours*2 intervals}{1 hour}[/tex]

amount of intervals= 6 intervals

You determine that you can only walk a maximum of 5 dogs at a given time, that is, in each interval you can walk a maximum of 5 dogs. Then you can apply the following rule of three: if in 1 interval you walk a maximum of 5 dogs, in 6 intervals how many dogs do you walk a maximum?

[tex]amounts of dogs=\frac{5 dogs*6 intervals}{1 interval}[/tex]

amount of dogs= 30 dogs

The most amount of dogs that you can walk in a given day is 30 dogs.

Step-by-step explanation:

Since you have sales tax, you would do a 10% sales tax for 15 dollar

10/100 = x/15

Therefore you will calculate x and 100 divided by 15 which would be 6.6 repeated

You would round to the nearest tenth and get 6.6 then you would add 56.4 as in the tip+ month airtime usage and get 63 dollars.

Question 3 is- B. 8 ounces

Step-by-step explanation:

Answer:

7.9

Step-by-step explanation:

When a number (or multiple numbers) is placed between two lines like this | |, that is the absolute value grouping symbol. Absolute value is the distance between the grouped number(s) and another defined number. In this case there are no other given numbers so 0 is assumed.

Now, say a friend is driving to your house and you call them to ask how far away they are from arriving (in distance), and they say "Around negative 5 miles away." That doesn't make sense! Distance can never be negative, and because absolute value is the distance between a number and another, a number within that grouping symbol can never be negative if there is a solution. Therefore, |-7.9| would be 7.9, because -7.9 is that exact amount away from 0.

Step-by-step explanation:

Parallel lines have the same slope.

x -3y = 21

y = (21-x)/-3 ==== y = 1/3x -7

Substitute the values,

y = mx + c

5 = (1/3)(-6) + c

5 = -2 + c

c = 7

Thus, the equation is y = 1/3x + 7

An equation of the line that passes through the point (−6,5) and is parallel to the line x−3y=21 is y = 1/3x + 7.

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

We need to find an equation of the line that passes through the point (−6,5) and is parallel to the line x−3y=21.

Parallel lines have the same slope;

x -3y = 21

y = (21-x)/-3

y = 1/3x -7

Substitute the values;

y = mx + c

5 = (1/3)(-6) + c

5 = -2 + c

c = 7

Therefore, the equation is y = 1/3x + 7

Step-by-step explanation:

Expand

2x -  10 = 3x + 6 - 4x + 8

Step-by-step explanation:

Using the tangent ratio in the right triangle.

tan35° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{opp}{100}[/tex] ( multiply both sides by 100 )

100 × tan35° = opp , that is

opp ≈ 100 × 0.7002 = 70.02

Thus height of tree = 70.02 + 5 = 75.02 ft

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

Using the tangent ratio in the right triangle on the right.

tan40° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{25.17}{rope}[/tex] ( multiply both sides by rope )

rope × tan40° = 25.17 ( divide both sides by tan40° )

rope = [tex]\frac{25.17}{tan40}[/tex] = [tex]\frac{25.17}{0.839}[/tex] = 30 ft

Answer:

2:10; 3:15; 4:20; etc

Step-by-step explanation:

The equivalent rations can be found by finding a common factor for 1:5. Examples include 2:10, 3:15, 4:20, etc. All of these have a common factor and thus are the equivalent ratios to 1:5.

The equivalent ratio to 1:5 is 2:10,3:15,4:20, etc.

Given that,

Here the equivalent ratio could be determined by measuring the common factor.

Like 2:10 = 1:5

3:15 = 1:5

4:20 = 1:5

Therefore we can conclude that the equivalent ratio to 1:5 is 2:10,3:15,4:20, etc.

Answer: In 8 days it will decrease by 16 inches and  in 15 days the water depth changes by 30 inches.

Step-by-step explanation:

The water depth decreases at a rate of 2 inches per day so in this case if were to write it as an expression it will be -2x  where x is the number of days.

We will have to set it equal the total amount that it has decreased which will be y.

y= -2x    If x  represent the number of days we will put in the days and solve for y.

y = -2(8)

y = -16     This means that in 8 days it will decrease by 16 inches.

y = -2(15)

y= -30   This also means that in 15 days the water depth changes by 30 inches.
