I'm not really good at math but I would like to help.
If each call is $.08, then the card can call last for 250 minutes.
The call lasted 202 minutes. Divide 16.16 by .08.
Answer: If the point of the circle P has coordinates: P=(x,y)
sine (Angle) = y/r
cosine (Angle) = x/r
tangent (Angle) = y/xw
where r=sqrt(x^2+y^2) is the radius of the circle
Example:
P=(3,4)=(x,y); x=3 and y=4
Radius of the circle: r
r=sqrt(x^2+y^2)
r=sqrt(3^2+4^2)
r=sqrt(9+16)
r=sqrt(25)
r=5
sin(Angle)=y/r
sin(Angle)=4/5
cosine(Angle)=x/r
cosine(Angle)=3/5
tangent(Angle)=y/x
tangle(Angle)=4/3
Answer:
k= 4/3
Step-by-step explanation:
distribute 9 9k- 18=-6
add 18 to both sides 9k= 12
divide by 9
Answer:
48 pounds per square inch
Step-by-step explanation:
d = (1/2)n + 26
d = 50feet
50 = (1/2)n + 26
Subtract 26 from both sides
24 = (1/2)n
Multiply both sides by 2
48 = n
