to get t alone you need to divide it by pr
when you do that you also need to divide I by pr
so t = i/pr
Answer:
Option A is correct.
Step-by-step explanation:
The formula used for finding the volume of right cone is:
Volume of Right cone = (1/3)π.r².h
We need to find altitude i.e h
Volume of cone=V = 8579 m^3
Radius=r = 16m
Altitude =h =?
Putting values,
8579 = (1/3) * 3.14 * (16)^2*h
8579 = 1/3 * 3.14 * 256 *h
8579 = 267.95 * h
=> h = 8579/267.95
h = 32.0 m
So, Altitude of right cone is 32.0 m
Option A is correct.
Answer:
y = -x + 8
Step-by-step explanation:
In writing an equation of a line, keep in mind that you ALWAYS need the following information in order to establish a linear equation:
1. 2 ordered pairs (x,y) on the line
2. Slope
We'll use points (1, 7) and (0, 8).
Let (x1, y1) = (1, 7)
(x2, y2) = (0, 8)
Now that we have the two ordered pairs, substitute their values into the following slope formula:
m = (y2 - y1)/(x2 - x1)
m = (8 - 7) / (0 - 1)
m = 1 / -1 = -1
Therefore, the slope of the line, m = -1.
Next, we need to determine the y-intercept, (b). The<u> y-intercept</u> is the y-coordinate of the point (0, <em>b </em>) where the graph crosses the y-axis. The y-intercept is also the value of y when x = 0. Looking at the graph, we can see that it crosses the y-axis at point (0, 8). We used this point earlier to solve for the slope. The y-intercept, b = 8.
Therefore, the linear equation in slope-intercept form is: y = -x + 8.

Answer: C. 7.5%
Solve as decimal
0.5*0.15=0.075
Move two decimal points over
0.075 -> 7.5
Change back to percent
7.5%
8 ,the answer is 8 you just ignore the zeros and multiply 4x2=8
