There are 80 children. 45 of them are girls. The amount of boys is equal to:
That means there are 45 girls and 35 boys.
The ratio of boys to girls is: 
Simplify:
Your answer is 7:9
1 triangle: 2*6 + 1*5
2 triangles: 2*6 + 2*5
3 triangles: 2*6 + 3*5
So for n triangles: p = 2*6 + n*5 = 12 + 5n
Answer:
I got x<equal to -11 or x>equal to4
Step-by-step explanation:
x^2+15x+44=0
(x+4)(x+11)=0(Factor left side of equation)
x+4=0 or x+11=0(Set factors equal to 0)
x=−4 or x=−11
Check intervals in between critical points. (Test values in the intervals to see if they work.)
x<−11(Works in original inequality)
−11<x<−4(Doesn't work in original inequality)
x>−4(Works in original inequality)
Answer:
x<−11 or x>−4
Answer:
20 feet
Step-by-step explanation:
Remember the Pythagorean theorem,
x^2 + y^2 = n^2
in this case
x= 16
y = 12
so substitute back into the equation
16^2 + 12^2 = n^2
256 + 144 = n^2
400 = n^2
sqrt ( 400) = n
20 = n
