Answer:
Step-by-step explanation:
If the 3.5 is supposed to represent a side length then 2.5² = 12.25 units²
20.25 or 20&1/4
100%-15
135%-x
100x=2025
*divide each side by 100*
x=20.25
or
20&1/4
Answer:
Step-by-step explanation:
Let x represent the number of calls made with plan 1 in a month.
Let y represent the number of calls made with plan 2 in a month.
Plan 1 charges $25 per month for unlimited calls. This means that the total cost of x calls made with plan 1 in a month would be $25
Plan 2 charges $15 per month plus $0.04 per call. This means that the total cost of x calls made with plan 1 in a month would be
15 + 0.04x
a) for the number of calls for which Plan 1 is more economical than Plan B, it becomes
25 < 15 + 0.04x
25 - 15 < 0.04x
10 < 0.04x
0.04x > 10
x > 10/0.04
x > 250
b) plan 1 would be more economical when the calls per month exceed 250.
Answer:
It is a rational number
Step-by-step explanation:
3/8 = 0.375
The set of rational numbers is of measure zero on the real line, so it is "small" compared to the irrationals and the continuum.
Any rational number is trivially also an algebraic number.
81
(-9)(-9) is 81
Multiplying two negatives gives a positive
