Answer:
B. The rate at which the balloon is rising.
Step-by-step explanation:
Mathematically speaking, the slope of the line represents the change in dependent variable (Height) divided by the change in independent variable (Time). According to the graph, a postive change in time leads to a positive change in height, meaning that slope is positive. Physically speaking, the slope represents the rate of change at which the height of the ballon is rising.
Hence, correct answer is B.
All exterior angles of n-gon always add up to 360°
To find the number of sides:
Answer:
41 minutes
Step-by-step explanation:
We are given;
Time spent on homework = 90 minutes
Time spent reading = 2/3 hours = 2/3 × 60 minutes = 40 minutes
Time spent making lunch = 540 seconds = 540/60 minutes = 9 minutes
We want to find how many more minutes Roberto spent doing homework than he did reading and making his lunch.
Thus;
Time spent on reading and making lunch = 40 + 9 = 49 minutes
Hence, the word "how many more" means we will subtract 49 from 90.
So, "how many more minutes" = 90 - 49 = 41 minutes

Hi!!
Okay, the discriminant is -36, and using the quadratic equation, it should be
-1 +/- 3<em>i</em>
Answer:
<span>y=4.98</span>
Explanation:
First, find the constant of proportionality , k.
<span>y=kx</span>
<span>21=7k</span>
<span>k=3</span>
We now start over and solve for y using the new value of x and the obtained value of k.
<span>y=<span>(3)</span><span>(1.66)</span></span>
<span>y=<span>4.98</span></span>
