Answer:
28 units^2
Step-by-step explanation:
1. First, let's divide this figure into two shapes: a square and a trapezoid. (Look at the image below explanation for division).
2. Next, we should know the area formulas of the square and trapezoid.
- Square:
, where s = side
, where a and b = top and bottom and h = height
3. Solving Area of Square and Trapezoid
. Area of square is 16
. Area of trapezoid is 12.- 16 + 12 = 28
Therefore, the area of the figure is 28 units^2.
There is a lot of numbers
Algebraically you could represent it like this
2*5 + x*3 + y*4 = 25 Multiply 2*5
10 + 3x + 4y = 25 Subtract 10 from both sides.
3x + 4y = 15 Now try this. Let y = 2
3x + 4*2 = 15
3x + 8 = 15 Subtract 8 from both sides.
3x = 15 - 8
3x = 7 Ordinarily you would divide by 3 but the question doesn't let you.
7 is a neat number. You could use 4 + 3
So one answer is
2 fives.
3 Fours
1 Three
You could also do
2 fives
5 threes. Nothing says you must have a four.
You can also do.
3 fives
1 four
2 threes There is nothing to say you can't have another 5
Answer:
Percentage of free time Gary spends on playing video games and using internet = 54.29%
Step-by-step explanation:
Given:
Gary spends 10 hours per week on the internet.
Gary spends 9 hours per week on video games.
Gary has 5 hours free time per day.
To find the percentage of free time Gary is using to play video game and use the internet.
Solution:
Total number of hours of free time Gary has per week = 
<em>[As there are 7 days in a week so we multiply by 7]</em>
Total number of hours of free time Gary spends on playing video games and using internet per week =
Percentage of free time Gary spends on playing video games and using internet per week can be calculated as :
⇒
⇒ 
⇒ 54.29% (Answer)
