Answer:
x = 16.8
Step-by-step explanation:
The ratio of corresponding sides is equivalent to the ratio of the perimeters.
Then using proportion
=
( cross- multiply )
5x = 84 ( divide both sides by 5 )
x = 16.8
Basing on the description, a parabola opening up with vertex at origin, the formula with vertex at origin is used, x^2 = 4py. p is the focus and so with the dimensions given, we obtain a 0.25 and that is the distance of the focus to the vertex.
3 hours for small = 3s
4 hours for large = 4b
3s + 4b <span>≤ 40 hrs total</span>
3s + 4b ≥ 12 paintings
Constraints:
less than or equal to 40 hrs
more than or equal to 12 paintings
Then you would graph it
Hope this helps :)
Answer:
Look at the explanation for the answer!
Step-by-step explanation:
P = s*4
A = base*height
So what I did was the terms that were alike like this: (5x -19x)+(20y+36y)+4.27xy+9.11. Then I simplified and got -14x+56y+4.27xy+9.11. The terms 4.27xy and 9.11 were not in ()'s because they were the only ones with an alike term. Hope that helps and also try to doing the steps and see what you get. If you get it wrong look to see where you messed up and try again! If I am wrong please notify me, I would appreciate it!
