One of the Ekati mine’s pipes,called the Panda pipe, has
northern and southern gates.
A communications tower
stands 100 m outside the north
gate. The tower can be seen from
a point 300 m east of the south
gate at camp A.
a) The distance between
camp A and camp B is 600 m.
Calculate the diameter
of the Panda pipe.
b) Calculate the distance from
camp B to the tower.

Answer:
y = + 2
Step-by-step explanation:
The slope of the line that has an x intercept of (2,0) and y-intercept of (0,-6) is:
Slope(s) = Change in y ÷ change in x
s = = 3
The slope of the perpendicular line to this line with slope of 3 has to have a slope of -1 ÷ 3 =
Reason: The product of slopes of lines perpendicular to each other have to be -1
So the slope of the perpendicular line that passes through (-6,4) is
As mentioned earlier, we derive a slope of a line by dividing the change in y by the change in x
Taking another point (x,y) on the line,
=
=
y - 4 = x - 2
y = x + 2
To find the slope-intercept equation of a line that passes through a given point and is perpendicular to another line, we can determine the slope of the given line and use it to find the equation.
To find the slope-intercept equation of a line, we need to know the slope and the y-intercept. Since the line that this problem is referring to is perpendicular to a line with an x-intercept of 2 and a y-intercept of -6, we can determine the slope of the line we are looking for by taking the negative reciprocal of the slope of the given line.
The slope of the given line is found using the formula: slope = (y2 - y1) / (x2 - x1)
Once we have the slope, we can use the point-slope form of a linear equation to find the equation of the line that passes through (-6,4) and has the determined slope. Finally, we can rearrange the equation to obtain the slope-intercept form, which is y = mx + b, where m represents the slope and b represents the y-intercept.

B.unlikely
C.neither unlikely nor likely
Answers
The likelihood of selecting a green marble is neither unlikely nor likely , Option C is the right answer.
What is Probability ?
Probability is the study of likeliness of an event to occur and it has a arrange of 0 to 1 , where 0 represents unlikeliness and 1 indicates certainty.
It is given in the question that
The probability of randomly selecting a green marble from a bag of 20 marbles is 1/2 .
which means the number of green marbles is 10 .
A (1/2) "half" Probability indicates neither unlikely nor likely.
Therefore Option C is the right answer.

and that'll be the number of hours after 9:00 AM. When we find out what ' T ' is,
we'll just count off that many hours after 9:00 AM and we'll have the answer.
-- The first car started out at 9:00 AM, and drove until the other one caught up
with him. So the first car drove for ' T ' hours.
The first car drove at 55 mph, so he covered ' 55T ' miles.
-- The second car started out 1 hour later, so he only drove for (T - 1) hours.
The second car drove at 75 mph, so he covered ' 75(T - 1) ' miles.
But they both left from the same shop, and they both met at the same place.
So they both traveled the same distance.
(Miles of Car-#1) = (miles of Car-#2)
55 T = 75 (T - 1)
Eliminate the parentheses on the right side"
55 T = 75 T - 75
Add 75 to each side:
55 T + 75 = 75 T
Subtract 55 T from each side:
75 = 20 T
Divide each side by 20 :
75/20 = T
3.75 = T
There you have it. They met 3.75 hours after 9:00 AM.
9:00 AM + 3.75 hours = 12:45 PM . . . just in time to stop for lunch together.
