Answer: Here we are looking for the least common multiple (LCM) between 9 and 25, this is the first number which the sets {9, 18 ,27...} and {25, 50, 75...} have in common, where the first set is the set of the packages with a baseball card, and the second is the one with the football card.

the LCM between two numbers is

LCM(9,25) = 9*25/(gcd(9,25))

where gcd is the greatest common divisor between 9 and 25, in this case is 1, because 9 is only divided by 3, and 25 is only divided by 5.

then LCM (9,25) = 9*25 = 225.

then in the 225 package, you will have a football card, and a baseball card.

Which is the best linear model for the data shown in the scatter plot?​
Studentka2010 [4]

The best linear model for the data that's illustrated will be y = 10x + 5

<h3>What is a linear model?</h3>

It should be noted that a linear model simply means model where the terms are added. It should be noted that this can be used in connection with the regression model.

Here, the best linear model for the data will be:

= (10 × x) + 5

= 10x + 5

Therefore, the best linear model for the data that's illustrated will be y = 10x + 5.

A boutique prices merchandise by adding 80%. It later decreases by 25% the price of items that do not sell quickly. Does the ord
k0ka [10]
The order you apply the adjustments does make a difference because the percents that are applied will be applied to different amount.  

For example, 80% of 100 = $80.  The price would be $180.

Decreasing this by 25% 25% of 180 = $45; 180-45 = $135.  

25% of 100 is not the same as 25% of 180.

A countertop is 18 feet long and 5 feet wide.
madam [21]

Answer:

The countertop is  8.37 square meters

Step-by-step explanation:

Let

L ----> the length of the countertop

W ----> the width of the countertop

we know that

The area of rectangle (countertop) is equal to

A=LW

we have

L=18\ ft\\W=5\ ft

Remember that

1\ ft=0.305\ m

To convert feet to meters multiply by 0.305

so

L=18\ ft=18(0.305)=5.49\ m

W=5\ ft=5(0.305)=1.525\ m

<em>Find the area in square meters</em>

A=(5.49)(1.525)

A=8.37\ m^2
