7 hours 12 minutes
6 hours 46 minutes
6 hours 53 minutes
--------------------------sum
Total: 19 hours 111 minutes, which converts to (19 × 60) + 111 = 1140 + 111 = 1251 minutes
Calculate average time by dividing by 3: 1251 / 3 = 417 minutes, equivalent to 6 hours 57 minutes, which is the average delivery duration.
The equation representing the circle centered at (-27, 120) that passes through the origin is:
Solution:
The general equation of a circle is expressed as:
Where,
(a, b) denotes the center of the circle
r signifies the radius
Given the center as (-27, 120)
Thus;
a = -27
b = 120
Considering it intersects the origin, meaning (x, y) = (0, 0)
Substituting (a, b) = (-27, 120) and (x, y) = (0, 0) into the equation
Input 
= 15129 and (a, b) = (-27, 120) into the equation
Hence, the equation characterizing the circle is determined

Here’s a chart to aid in understanding the staircase issue. Observe that for 1 step, there is 1 block; for 2 steps, 3 blocks; for 3 steps, 6 blocks, and so forth. Note that the blocks corresponding to each step are a combination of that step and all the blocks used in the steps beneath it. For instance, constructing 14 steps requires 105 blocks.
If you’re familiar with summation, you would sum the blocks for each step with all the steps below it. For example, 5 steps would require 5 + 4 + 3 + 2 + 1, resulting in a total of 15 blocks. I hope this helps you begin. As for the second part, I'm confused by the problems since they don't represent equations. NO equal signs
glad if it helps
Answer: the independent variable is time (t). The dependent variable is distance (d).
Step-by-step explanation: an independent variable is defined as one whose variation is not dependent on another. In this case, time acts as the independent variable because it continues to pass irrespective of other factors. The distance is considered the dependent variable, as Jillian's distance traveled relies on the duration she spends walking and jogging.
In January, 20% of the total savings were achieved. To find this percentage, first determine the difference (increase) between the two amounts you’re scrutinizing. The increase is calculated as New Number - Original Number. Next, divide this increase by the original figure and then multiply by 100 for the percentage increase.
