Answer:
The time will be 10:42:40 am. = 10:42
am.
Step-by-step explanation:
∵ The time of 10 questions = 10 × 30 = 300 sec. ÷ 60 = 5 min.
∵ The time of 15 questions = 15 × 40 = 600 sec. ÷ 60 = 10 min.
∵ The time of 12 questions = 12 × 2 = 24 min.
∵ The total of the questions = 10 + 15 + 12 = 37
∵ The time of total rests between the questions = 36 × 5 = 180 ÷ 60 = 3 min.
* Note: (The rests time less than the number of questions by 1 because there is no rest after the last question)
∵ The time of sharpens = 2 × 20 = 40 sec. ÷ 60 =
min.
∴The total time of the test = 5 + 10 + 24 + 3 +
=
min.
Answer:
So (1,3) is <em>a</em> vertex (out of two) of the hyperbola.
Step-by-step explanation:
The vertices are marked by the dot on the hyperbola.
They are (1,3) and (1,-7).
However, (1,-7) is not on the list of answer choices, but (1,3) is.
So (1,3) is a vertex (out of two) of the hyperbola.
Answer:
(f o g)(x) = 0.8x - 15
Step-by-step explanation:
(f o g)(x) = f(g(x)) = applying first g(x), and then using that result as input value for f(x).
so, first we discount by 20% and use g(x)
g(x) = 0.8x
and then we use that in f(x)
f(0.8x) = 0.8x - 15
and that is the result.

Answer: 16</h3>
Work Shown:
fl oz = fluid ounce
qt = quart
32 fl oz = 1 qt
4*32 fl oz = 4*1 qt
128 fl oz = 4 qt
If she has 128 fluid ounces of water, then she can fill up the 8 fl oz water bottle a total of 128/8 = 16 times. This of course assumes that there aren't any spills.
