If you could put in the tablet.

But the equation would be: a_n = a_1 (r)^(x-1)

with a_1 being the first category

r being 5 how much brighter than the day before is

and x is what nr. in the sequence it is

But I'm not sure as I cannot see the table

Answer:

10 Times

Step-by-step explanation:

From the statement "Each category in the tablet is 5 time brighter than the category above it." It can be inferred that the brightest portion of the day must be 5 times the less bright day. This means that:

Dim = 2

Brightest = 5 times dim

               = 5 * 2

               = 10

Eddi Din [679]

Answer:

$20

Step-by-step explanation:

Here, the broker charges $10 per trade. So, it doesn't matter how much you do trade, the broker will charge $10 PER TRANSACTION.

Samantha bought stocks worth 2500 (1 transaction)

Samantha sold these again for 2750 (1 transaction).

So there were 2 trades made by Samantha.

So broker would charge $10 + $10 = $20

The top surface of a desk has a length of 5.6 ft and the length is 4 times its width what is the width of the desk
IgorLugansk [536]

Answer:

<u>The width of the top surface of the desk is 1.4 feet.</u>

Step-by-step explanation:

1. Let's review all the information given for solving this question:

Length of the top surface of a desk = 5.6 feet

Width of the top surface of a desk= x

2. Let's find the width of the top surface of the desk

Length of the top surface of a desk = Four times the width

5.6 = 4x

5.6/4 = 4x/4 (Dividing by 4 at both sides)

1.4 = x

<u>The width of the top surface of the desk is 1.4 feet.</u>
