Answer:

Step-by-step explanation:
The formula of a circumference of a circle:

r - radius
We have <em>r = 8</em>. Substitute:


Answer:
84 months
Step-by-step explanation:
I × 100 = P × R × T
I = interest = $245
P = principal = $1750
R = rate = 2%
T = time(in years) = ??
245 × 100 = 1750 × 2 × T
24500 = 3500T
24500/3500 = T
7 = T
To convert the time to month:
7 × 12 = 84 months
-7.5 times 1/3=-2.5
To take 1/3 of something, multiply the original by the fraction.
This is a cube root, so we look for factors of 162 which are perfect cubes.
Find the prime factors of 162:-
162 = 2 * 3 * 3 * 3* 3
27 = 3^3 is a perfect cube
162 = 6 * 27
so ^3√ 162 = ^3√6 * ^3√27 = ^3√6 * 3
so the simplest form is 3 ^3√6
Answer:
- 1700: $50
- 2000: $60
- 7000: $90
Step-by-step explanation:
You can read the answers from the graph. Find the usage on the horizontal scale, and look at the vertical scale to find the corresponding charge.
__
<h3>1700 gallons</h3>
The value 1700 is between 1000 and 2000, so will be between 1 and 2 on the horizontal scale. The graph is flat in that region. The charge is $50.
__
<h3>2000 gallons</h3>
The graph has a jump at 2 on the horizontal scale. The solid dot tells you that the charge is $60.
__
<h3>7000 gallons</h3>
At 7 on the horizontal scale, the graph is increasing from 80 to 100. At 7000 gallons, the line passes through the grid intersection indicating the charge is $90.
