Answer = 13%
Explanation:
Total number of people who bought a hot sandwich = 2 + 7 + 6
Total number of people who bought a hot sandwich = 15
Total number of people who bought a hot sandwich and did not buy a drink = 2
Visitors who purchased a hot sandwich and did NOT buy a drink = 2 /15
Percentage of Visitors who purchased a hot sandwich and did NOT buy a drink = 2 /15 *100
= 13.2222%
Rounding off would be 13%
Answer:
The speed of the airplane in still air is 550 mph.
The speed of the wind is 50 mph.
Step-by-step explanation:
speed = distance / time
distance = speed * time
or simply
d = st
Let v be the speed of the airplane with no wind.
Let w = speed of wind
With the wind:
d = 1800; s = v + w; t = 3
1800 = 3(v + w)
Against the wind:
d = 1800; s = v - w; t = 3.6
1800 = 3.6(v - w)
We have a system of two equations:
3(v + w) = 1800
3.6(v - w) = 1800
Divide both sides of the first equation by 3. Divide both sides of the second equation by 3.6.
v + w = 600
v - w = 500
Add the equations.
2v = 1100
v = 550
The speed of the airplane in still air is 550 mph.
v + w = 600
550 + w = 600
w = 50
The speed of the wind is 50 mph.
Answer:
4
Step-by-step explanation:
Take the second term and subtract the first term
-1 - -5
-1 +5 = 4
Check with the third term subtracting the second term
3 - -1
3+1 = 4
The common difference is 4
To find 176 out of 800, you must do this.
176/800(to find the decimal form)=0.22
Then you multiply the decimal form with 100
0.22×100=22%
So, 176 out of 800 is 22%.
Answer:
A. p=6.25h
because
6.25 (2) = p 12.50
6.25 (4) = p 25.00
6.25 (6) = p 37.50
6.25 (8) = p 50.00
