Answer:
The total cost of the ink supplies can be represented in two different ways, as follows:
a. 3p (1+r)
b. p * (1+ r) * 3
Step-by-step explanation:
a) Data and Calculations:
Number of printer cartridges bought = 3
Sales tax rate = 7%
The total cost can be represented as:
Total cost = 3p (1+r)
where p = the price of a printer cartridge
and r = the sales tax rate
Alternatively, the total cost can be represented as:
Total cost = p * (1+ r) * 3
b) Whichever expression is used, the total cost derived will remain the same. The first expression includes the sales tax in the total cost, while the second expression includes the sales tax in the cost of the unit before arriving at the total cost.
Answer:
The speed at which Anna travel with her bike is 3 miles per hour .
Step-by-step explanation:
Given as :
The distance cover by Anna = 6 miles
The time taken by the Anna to cover the distance = 2 hours
Let The speed in miles per hour = s miles per hour
<u>Now, As we know </u>
Speed = 
So, s = 
or, s = 3 miles per hours
So, Speed = 3 mph
Hence The speed at which Anna travel with her bike is 3 miles per hour . Answer
You would just do 5.7-8.1, which is -3.6 degrees Celcius. Hope I helped!
If

, then angle

is obtuse and triangle with sides a, b, c is obtuse triangle.
In an arbitrary triangle can be only one obtuse angle, and the side which lies opposite to the largest angle is the largest. Then since <span>angle

is opposite the side of length a</span> you can conclude that a>c and a>b.
