Answer:
- 3/2
- it is the ratio of oil to vinegar in the dressing
- y = 3/2x
Step-by-step explanation:
1. The table can be filled in like this:
- (x, y)
- (0, 0)
- (2, 3)
- (4, 6)
- (6, 9)
The constant of proportionality is the ratio of y to x:
k = 3/2
__
2. The meaning of the constant of proportionality is just what it is defined to mean: the ratio of oil to vinegar in the dressing.
__
3. The equation is y=kx, where k is the value in part 1:
y = (3/2)x
LORAN follows an hyperbolic path.
The equation of the hyperbola is: 
The coordinates are given as:
The center of the hyperbola is
The distance from the center to the focal points is given as:
Square both sides
The distance from the receiver to the transmitters is given as:
Divide both sides by 2
Square both sides
We have:
This gives
The equation of an hyperbola is:
So, we have:
Hence, the equation of the hyperbola is:

Answer:
ANSWER-) 3 litres =3000ml
capacity of 1 tube =75ml
NO. OF TOOTH PASTE REQUIRED = 3000/75=40 tubes.
Let's V the speed of the girl in step
v the speed of the escalator in step
L the length between ground and floor.
V*60+v*60=L ==> V+v=L/60
V*90-v*90=L ==> V-v=L/90
2V=L(3+2)/180
==>V=5L/360
Time to climb (in step) with v=0 (escalator standing still)
V*t=L==> t=L/V=L/(L*5/360)=72
The girl will count 72 steps.
Answer:
-3
Step-by-step explanation:
You cannot simplify this question anymore, for it is already a whole number.
Steps:
-3/1
Eliminate the fraction bar and one...
-3
(Anything over one, is whole...so if I were to put 98384743/1, it would just be 98384743.)
