50 girls attended the trip.
80 boy + 50 girls = 130 total students
8x10 =80
5x10=50
multiply both by 10.
Given :
P(-9, -4), Q(-7, -1), R(-2, 5), S(-6, -1).
To Find :
The slope of line PQ.
Solution :
We know , slope is given by :
Therefore, the slope of line PQ is 2/3.
Hence, this is the required solution.
Answer:
1. 70.
2. 29.
3. 442.5
4. 289.
5. 632.
Step-by-step explanation:
The key to doing these is to split the polygons into rectangles, triangles or trapezoids as appropriate.
For example, number 1 consists of a rectangle area 8 * 8 and another of 3* 2.
So the area = 64 + 6 = 70 unit^2.
2. The area = sum of 3 rectangles 1*1 + 4*6 + 2*2.
3. Area = 11*15 + 11*15 + 1/2*15*15
4. Area = 18*12 + 1/2 * 6 * 15 + 1/2 * 7 * 8.
5. Area = area of 2 rectangles + area of a trapezoid.
= 18 * 24 + 4*10 + 1/2(12 + 20) * 10.
Y= -2/3 +6 bc...
(-3,8)
y=mx+b
8= -2/3(-3) +b
8=2+b
-2 -2
6=b
Answer:
y=-1/2x - 3
I think this is it, its been a while though.
