Answer: 79 minutes</h3>
Explanation:
From 9:24 AM to 10:24 AM is 60 minutes (aka 1 hour)
Then from 10:24 AM to 10:43 AM is another 19 minutes (because 43-24 = 19)
The full duration is 60+19 = 79 minutes
Answer:
Step-by-step explanation:
Let's solve the given system of linear equations:
a+b = 13
0.750 + 1.15b = 12.55
Let's eliminate b. To do this, solve the first equation for b, obtaining b = 13 - a, and then substitute 13 - a for b in the second equation:
0.750 + 1.15(13 - a) = 12.55.
Next, subtract 0.750 from both sides, obtaining: 1.15(13 - a) = 11.8
Dividing both sides by 1.15 yields 13 - a = 10.26
Then a = 13 - 10.26, or a = 2.74.
Since a + b = 13, b = 13 - 2.74, or 10.26
This person bought 2.74 pounds of apples and 10.26 pounds of bananas.
Answer:
7 bucks
Step-by-step explanation:
x*.8=5.62
divide both sides by .8
x=7
Answer: Absolute minimum: f(-1) = -2
Absolute maximum: f() = 12.5
Step-by-step explanation: To determine minimum and maximum values in a function, take the first derivative of it and then calculate the points this new function equals 0:
f(t) =
f'(t) =
f'(t) =
f'(t) = = 0
For this function to be zero, only denominator must be zero:
t = ±
≠ 0
t = ± 5
Now, evaluate critical points in the given interval.
t = and t = - 5 don't exist in the given interval, so their f(x) don't count.
f(t) =
f(-1) =
f(-1) =
f(-1) =
f() =
f() = 12.5
f(5) =
f(5) = 0
Therefore, absolute maximum is f() = 12.5 and absolute minimum is
f(-1) = .
