Part (a)
<h3>Answer:
2(2.4+w) = 14.2</h3>
--------------
Explanation:
L = 2.4 = length
W = unknown width
The perimeter of any rectangle is P = 2(L+W)
We replace L with 2.4, and replace P with 14.2 to get 14.2 = 2(2.4+w) which is equivalent to 2(2.4+w) = 14.2
========================================================
Part (b)
<h3>Answer:
w = 4.7</h3>
--------------
Explanation:
We'll solve the equation we set up in part (a)
2(2.4+w) = 14.2
2(2.4)+2(w) = 14.2
4.8+2w = 14.2
2w = 14.2-4.8
2w = 9.4
w = 9.4/2
w = 4.7
The width must be 4.7 cm.
Answer:
37500
Step-by-step explanation:
3% of 1250000
That is (3/100)*1250000
The answer is 37500
Step-by-step explanation:
357-200 is 157 extra minutes (we are only counting the extra minutes)
157*0.25 is 39.25 (this is how much is the extra minutes in total cost)
therefore, add 39.25 and 29.99
29.99+39.25 is 62.24
Therefore, the total bill was $62.24
hope this helps :)
Have a nice day !
