Y = 200x.....the airplane travels 8000 miles in 40 hrs
Answer:
(a) 
(b)The boiling point of water in Celsius scale is 100°C.
(c)The setting in Celsius scale is 26.7°C.
Step-by-step explanation:
Given that,the formula is
......(1)
(a)
Given that,

[ subtracting 32 from both sides]


......(2) [Multiplying
]

(b)
Given that, the boiling point of water is 212°F.
Putting F=212 in equation (2)




The boiling point of water is 100°C.
(c)
Given that, a house thermostat is set at 80 degree.
Putting F=80 in equation (2)



The setting in Celsius scale is 26.7°C.
10% of 140 is 14 so just add 14 to 140
140+14=154.
<span>Perimeter =2w+2L= 520.
We can solve this by understanding that the area is maximized by a square
Therefore L=w.
p=2w+2w=520=4w
w=130
Area
A=wL=130(130)= 16900 square yards</span>
The total length of the ribbon used is expressed as r and is a product of the number of gifts (g) and the length of ribbon tied in each gift. This relationship may be expressed by the equation,
r = (25) x (g)
