Answer:

Part 1: 2.4 + x

Part 2: 4(2.4 + x) = 14.8

Step-by-step explanation:

2.4 + x is the total distance covered every day.

We know that after 4 days, Bijan has run 14.8 miles, so in total he has run 4(2.4 + x) miles, which is equal to 14.8.

Extra: Here's how to work out x!

4(2.4 + x) = 14.8

9.6 + 4x = 14.8

4x = 5.2

x = 1.3

Hope that helps!

If the basic measuring unit in base-7 is 49 circles, what does the measuring unit of size .001seven look like

Serjik [45]

The measuring unit is the standard unit of a quantity

The measuring unit of size 0.001 is represented by one millionth circle

<h3>How to determine the unit of base 0.001</h3>

The basic measuring unit in base 7 is given as:

49 circles

The above can be represented as:

Base 7 = 49 circles

Represent the base with n.

So, we have the following rule

$Circle = n^2$

For measuring unit 0.001, we have:

$Circle = 0.001^2$

Evaluate the square

$Circle = 0.000001$

This means that,

The measuring unit of size 0.001 is represented by one millionth circle

Kim works as a sale person for a car dealership. Her base salary is $85 per day. She gets paid commission of 7.2% of anything sh

amid [387]

Answer:

$939.04

Step-by-step explanation:

To calculate her gross pay, we need to take into consideration, her total pay for the 4 days and her commission based on the total amount of goods she sold.

Firstly, her daily base salary is $85, since she worked for 4 days, her total salary for the four days will be $85 * 4 = $340.

Now, she is to earn 7.2% of $8,320 as commission. The amount of her commission is thus 7.2/100 * 8,320 = 599.04

Her gross pay is thus $599.04 + $340 = $939.04
