Answer: x=5
Step-by-step explanation: u can just simplify it
Answer:
ok so the answer is x>−99/4
Step-by-step explanation:
Let's solve your inequality step-by-step.
(−

Answer:
Step-by-step explanation:
Y = kx
25 = k150
25/150 = k
0.166 = k
When the value of x = 60
y = (0.166)(60)
y = 9.96
The required temperature at the height of 1200 meters is 13 degree Celcius.
Given that,
Temperature drops an average of 1 degree celsius for every 100 meters that a hot air balloon rises.
The temperature is 25 degrees celsius on the ground.
The approximate temperature is 1200 meters above the ground is to be determined.
<h3>What are functions?</h3>
Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
The expression of for temperature drops an average of 1-degree celsius for every 100 meters that a hot air balloon rises.
Let x be the height in meters and y be the temperature in degrees celcius
y = -x/100 + 25
For temperature 1200 meters above ground
x = 1200
y = -1200/100 + 25
y = -12 + 25
y = 13
Thus, the required temperature at the height of 1200 meters is 13 degrees Celcius.
