6 hours Zoey can expect from the tablet on a full battery charge if the battery dropped by 33%, from 100% to 67%.
<h3>What is percentage?</h3>
It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
We have:
Zoey wants to use her computer tablet throughout a 6-hour flight. Upon takeoff, she uses the tablet for 2 hours and notices that the battery dropped by 33%, from 100% to 67%.
Let's suppose x hours Zoey can expect from the tablet on a full battery charge.
The value of x can be calculated using:
x = (2×100)/33
x = 200/33
x = 6.06 ≈ 6 hours
Thus, 6 hours Zoey can expect from the tablet on a full battery charge if the battery dropped by 33%, from 100% to 67%.

Answer:
B) 30min
Step-by-step explanation:
Start with 2 and continue to multiply that by 2 until you get 128
2 x 2 = 4
4 x 2 = 8
8 x 2 = 16
16 x 2 = 32
32 x 2 = 64
64 x 2 = 128
Then start with what you think could be the right answer based on how many intervals there are.
You know it can't be 15 because there definitely isn't enough and you know its not 1hr because theres way more than 3.
So you're left with either B) 30min or C) 45min
It has to be B) 30min because there are 6 intervals and 30min goes into an hour twice, meaning that if every 2 intervals is an hour there are 3 hours.
Answer:
126.5 cm
Step-by-step explanation:
First, find the area of the rectangular shape at the bottom.(think of this as 2 separate shapes then add their areas together to find the final area)
11x8=88 cm
Next, find the area of the triangle.
Area of triangle = base x height /2
11x7=77
77/2=38.5
88+38.5=126.5 cm
X-4y=-11<=> -5x + 20y = 55
<span> 5x - 7y = -10</span>
=>0*x + 13*y = 45 => y =45/13 => x = 4*(45/13) -11 = 180/13 -11 =>
x = 37/13;
