Let x = the speed of the plane, mph
Let y = the speed of the wind., mph
When flying with a tailwind, the effective speed of the plane is (x + y), therefore
x + y = 376 (1)
When flying back against the wind, the effective speed is (x-y), therefore
x - y = 312 (2)
Add (1) and (2).
2x = 376+312 = 688
x = 344 mph
y = 376 - x = 32
Answer:
Plane: 344 mph
Wind: 32 mph
Answer:
1. 50 = 5x+15
2. 50 = 3x+20
3. 7
4. 10
5. Skating Rink
Step-by-step explanation:
1. As the maximum amount of money is 50 dollars, you are given that there is a 5 dollar entry *per* person, alongside the 15 room rental fee added on. That is where the equation 5x+15 = 50 comes from
2. The same can be said with the skating rink, with different numbers. 3 *per* person plus the extra 20 room rental fee.
3. 50 = 5x+15 can be solved by subtracting 15 by both sides. This gives us 35=5x and dividing by 5 will give us 7 = x
4. 50 = 3x+20 can be solved by subtracting 20 by both sides. This gives us 30=3x and dividing by 3 will give us 10 = x
5. As 10>7, it's apparent that you can bring more people to the Skating Rink
Answer:
y = -1
Step-by-step explanation:
As we move from point (-5, -1)
to point (2, -1), x increases by 7 and y stays the same.
The slope of this line is thus m = [-1 - (-1)] / 7, or just m = 0.
This is a horizontal line. Its equation is y = -1.
Answer:
Surface area of the whole figure
Step-by-step explanation:
The surface area of the figure :
Surface area of the cylinder(excluding top)+Surface area of the cone(excluding bottom)
Radius of the cylinder=3 inch and Height of cylinder=13 inch
Surface area of the cylinder with one circular face

As, 

Surface area of the cone excluding base:

l= slant height=5 inch r= radius= 3 inch
Surface area of the cone =

Total surface area of the whole figure

A) this is not enough information to compare the mode.
For example:
{1,1,6,11,11]: mean 6, median 6, mode 1 and 11
{4,4,6,8,8} mean 6, median 6 mode, mode 4 and 8
