Answer:

12

Step-by-step explanation:

Create a ratio

AB : DE

5 : 4

BC : EF

15: x

5/4 = 15/x

5x = 15*4

5x = 60

x = 12

EF = 12

What is the GCF of 48m5n and 81m2n2?
Sever21 [200]

Answer:

To find the GCF of the two terms, continuous division must be done.

What can be used to divide both terms such that there is not a remainder?

Start small, let's take 2. It could be a GCF.

Move up higher, say 3. Yes, it can be a GCF.

To see if there might be a greater common factor, divide the constants by 3.

48/3 = 16

81/3 = 27

Upon inspection and contemplation, there is no more common factor between 16 and 27. So, 3 is the GCF.

Moving on, when it comes to variables. The variable with the least exponents is easily the GCF. For the variable m, the GCF is m2 and for n, the GCF is n.

Combining the three, we have the overall GCF = 3m2n

also the third one or c

Which situation describes a non-proportional relationship?
Pani-rosa [81]

Situation of non- proportional relationship :

The circumference of a circle with a radius of x units can be represented by = 2nx.

The perimeter of an equilateral triangle with a side length of x  units can be represented by y = 3x

The total surface area of a cylinder with a radius of 1 unit and height of x units can be represented by y = 2xx + 2x

The radius of a circle with a diameter of x units can be represented by y = \frac{1}{2}x

a proportional relationship is a relationship between two quantities in which the ratio of one quantity to the other quantity is constant. The graph of a proportional relationship is a line through the origin.

When ratios between quantities are not constant, a relationship may be linear but not proportional and the graph does not pass through the origin.

The graph shows the sales tax charged based

on the amount spent at a video game store in

a particular city. Does the graph show a linear

relationship? Is the relationship proportional

or nonproportional?

The graph shows a linear proportional

relationship because it is a line that contains

the origin.
