The answer is <span>The liquid must be in the cooler fewer than 10 minutes.
</span>
Let:
m - the number of minutes the liquid is in the cooler.
a - the starting temperature
The function is:
f(m) = a - 3 * m (Since the temperature decreases by 3°F each minute m, it has a negative sign)
Let:
m - <span>the number of minutes the liquid is in the cooler.
a - the starting temperature
</span>a = 90<span>°F
</span>
<span>The temperature of a liquid must stay above 60°F:
f(m) > 60
Thus:
</span>f(m) = a - 3 * m
f(m) > 60
a - 3 * m > 60
90 - 3m > 60
90 - 60 > 3m
30 > 3 m
30/3 > m
10 > m
Or m < 10. So the correct answer is The liquid must be in the cooler fewer than 10 minutes.
Answer:
t = 204
Step-by-step explanation:
Let t = initial number of trees
"remove 5 trees at the start of the season" means
(t - 5) remain
"each remaining tree made 210 oranges for a total of 41,790 oranges" means
( t - 5) * 210 = 41790
Now, you can solve for t:
(t-5)(210) = 41790 [just re-writing]
210t - 1050 = 41790 [distribute]
210t = 42840 [add 1050 to each side]
t = 204 [divide each side by 210]
There were initially 204 trees. After 5 were removed, the remaining 199 produced 210 oranges each for a total of 199*210 = 41790 oranges.
Answer:
Step-by-step explanation:
circumference=2πr=6.28
r=6.28/2π=3.14/π=3.14/3.14=1
area=πr^2=π×1²=π=3.14 units²
Answer:
there are two ways we can solve this problem the first way is in x-form and the second way is in y-form I will give you the answer for each of the ways.
Step-by-step explanation:
x-form: x=37-3y
y-form: y=37/3 - x/3
hope this helps if this was not the way you wanted me to solve it please let me know and I will do it the way you want me to do it.
It is D)19 bc 5x3=15 then 7-3=4 so 4x1=4 now 15+4=19
