Answer:
0 < cc + dd ≤ 11
Step-by-step explanation:
≤ means equal to or less than.
It has to be more than zero, obviously.
You have to double 1 and 50 to get 2 and 100
1:50 = 2:100
1x2=2
50x2=100
So the statement, <em>if she studied for 2 hours, she would have gotten 100%</em>, makes sense
Hope this helps!
Area = length * width = 4x * x = 4x^2.
4x^2 = 80
x^2 = 80/4 = 20
x = sqrt 20
Answer is 4.47 to nearest hundredth.
