Approx - 10%
72 students signed up for canoeing + the 23 students who signed up for trekking + the 13 students who signed up for both = 108 students
there are 120 students total, so you have to subtract 120 - 108 = 12
Now to find the percentage, you have to divide the number of students who didn't sign up for either, by the total
which is .1 = 10/100 = 10%
In the future, please post the full problem with all included instructions. After doing a quick internet search, I found your problem listed somewhere else. It mentions two parts (a) and (b)
Part (a) asked for the equation of the line in y = mx+b form
That would be y = -2x+9
This is because each time y goes down by 2, x goes up by 1. We have slope = rise/run = -2/1 = -2. This indicates that the height of the candle decreases by 2 inches per hour. The slope represents the rate of change.
The initial height of the candle is the y intercept b value. So we have m = -2 and b = 9 lead us from y = mx+b to y = -2x+9
----------------------------------------------------------------
Part (b) then asks you to graph the equation. Because this is a linear equation, it produces a straight line. We only need 2 points at minimum to graph any line. Let's plot (0,9) and (1,7) on the same xy grid. These two points are the first two rows of the table. Plot those two points and draw a straight line through them. The graph is below
Answer:
6 pounds of fertilizers are needed for garden area of 180 square foot.
Step-by-step explanation:
Let 'x' pounds of fertilizers be needed for 180 square foot garden.
Given:
4 pounds of fertilizer needed for an area of 120 square foot.
The area of the garden given is 180 square foot.
Now, as per question:
4 pounds of fertilizer is equivalent to an area of 120 square foot.
Therefore, 'x' pounds of fertilizer is equivalent to an area of 180 square foot.
Applying proportion and cross multiplying method, we get:
x 4
_ = _
180 120
120x=4 x 180
120x= 720
x = 720
_
120
x=6 LBS
Therefore, 6 pounds of fertilizers are needed for garden area of 180 square foot.
Step-by-step explanation:
Angle 3:
62+47=109
All angles in a triangle add to 180 degrees, so 180-109= 71 degrees
Angle 2:
Angles in a straight line always add to 180 degrees too,
so 180-62= 118 degrees
Angle 1:
Again, angles in a triangle add to 180,
so 180-22-118= 40 degrees
Angle 1: 40
Angle 2: 118
Angle 3: 71
Hope that helps :)
Answer:
(-4,-4)
Step-by-step explanation:
6x - 7y = 4
6(-4) - 7(-4) = 4
-24 + 28 = 4
4 = 4 This is correct to the first equation.
Now let us try the second equation.
-5x + 3y = 8
-5(-4) + 3(-4) = 8
20 - 12 = 8
8 = 8 This is also correct to the second equation.
Hope this helps, thank you !!
