Answer:
440 times
Step-by-step explanation:
First you need to find the total number of cubes each student recieves (25)
Now you put it into a ratio 11 : 25
After that make another ratio with 1000 and solve for x
x : 1000
25x = 11000
x = 440
The two points at a distance of 3 units from C with the same y coordinate are (-3, -5) and (-9, -5).
Step-by-step explanation:
Step 1:
First, we must plot the point C on the graph. Point C is on the third quadrant so the x value and the y value are negative.
The coordinate of C is (-6, -5).
We need to plot two points that are 3 units away from point C but have the same y coordinate i.e. y = -5.
Step 2:
So assume the two other points are A and B.
The y coordinates of A and B are -5. Only the x coordinate varies. So in order to get the coordinates of point A and B, we add and subtract 3 from the x coordinate of point C.
Point A = (-6+3, -5) = (-3,-5).
Point B = (-6-3, -5) = (-9, -5).
So two points at a distance of 3 units from C with the same y coordinate are (-3, -5) and (-9, -5).
Answer:
Original position: base is 1.5 meters away from the wall and the vertical distance from the top end to the ground let it be y and length of the ladder be L.
Step-by-step explanation:
By pythagorean theorem, L^2=y^2+(1.5)^2=y^2+2.25 Eq1.
Final position: base is 2 meters away, and the vertical distance from top end to the ground is y - 0.25 because it falls down the wall 0.25 meters and length of the ladder is also L.
By pythagorean theorem, L^2=(y -0.25)^2+(2)^2=y^2–0.5y+ 0.0625+4=y^2–0.5y+4.0625 Eq 2.
Equating both Eq 1 and Eq 2: y^2+2.25=y^2–0.5y+4.0625
y^2-y^2+0.5y+2.25–4.0625=0
0.5y- 1.8125=0
0.5y=1.8125
y=1.8125/0.5= 3.625
Using Eq 1: L^2=(3.625)^2+2.25=15.390625, L=(15.390625)^1/2= 3.92 meters length of ladder
Using Eq 2: L^2=(3.625)^2–0.5(3.625)+4.0625
L^2=13.140625–0.90625+4.0615=15.390625
L= (15.390625)^1/2= 3.92 meters length of ladder
