Go to the third pic for your answer. I got problem 4 wrong but it shows the correct answer.
If you multiply 23 by 12 you will get 276.
The length of the hypotenuse = √(-3^2 +1^2) = √10
The point -3,1 tell us the length of y is 1 and the length of x is 3.
This would make opposite = 1 and adjacent = -3
Sinθ = opposite/hypotenuse = 1/√10 = √10/10
Cosθ = adjacent/hypotenuse = -3/√10 = - 3√10/10
Tanθ = opposite/adjacent = 1/-3 = -1/3
Answer:
4 Blue chips
6 Yellow chips
10 Red chips
Imagine 20% as 2 of 10. We have 20 chips, and that's double of that. So if we have 2/10... we will have 4/20
Same with the yellow chips. Imagine 30% as 3 of 10, again double that... 6/20.
It doesn't directly say the percent of design a computer representation but we can infer that if we have 20% and 30%... that makes 50%, there is only 100 in a percent, so that means there is 50% left! We repeat the process where we envision 50% as 5 of 10, double that. Now we have 10 of 20, 50%!
Decimal: 3.5
350 divided by 100 = 3.5
Percentage: 350%
Move the decimal 2 times to the right
3.5 -> 350
Add a percent sign
