Answer:
15
Step-by-step explanation:
8+5=13
39/13=3
3*8=24(boys)
3*5=15(girls)
A=<4.60,7.20>
b=<5.10,2.70>
The scalar product, or the inner product, or the dot-product, is by summing the products of the respective directions,
a.b=4.6*5.1+7.2*2.7
=23.46+19.44
=42.9
Answer:
X > -1
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Answer:
2.193 and
Step-by-step explanation:
Area of Segment = πr²θ/360 -½r²sinθ
=π*3²*85/360-½*r²sin85
= 2.193cm²
volume of cone= ⅓πr²h
=⅓*π*3²*21
=198 cm³
To find Y intercept
You do y2-y1/ x2-x1
Your y2 is 12, y1 is 2
Your x2 is 2 , x1 is 3
So 12-3/2-3
12-3 is 9
2-3=-1
9/-1 is -9
So your slope is -9
