Answer: 25
Step-by-step explanation:
if she has 120 and if she has 20 leftover that means she used a 100. then u divide 100 by 4 cause it's a square and u get 25
For this case, we have the total of painters is 16, so to determine what percentage is painting the interior of the house, we make a rule of three:
16 ---------------> 100%
4 -----------------> x
Where "x" represents the% of painters who paint the interior of the house.
Thus, 25% of painters are painting the interior of the house.

Answer:
MN = sqrt(34)
Step-by-step explanation:
First, draw the segment FN. The diagonal, MN, of the prism is the hypotenuse of triangle NFM. Triangle NFM is a right triangle with legs FN and FM and hypotenuse MN.
Leg FM of triangle NFM has length 4 cm.
We need to find the length of leg FN.
Look at the base of the prism which is square UNAF. FN is a diagonal of that square. Now think of right triangle FUN with legs UN and UF, each of length 3 cm. We can find FN with the Pythagorean theorem.
(UF)^2 + (UN)^2 = (FN)^2
3^2 + 3^2 = (FN)^2
(FN)^2 = 18
FN = sqrt(18)
Now we know FN. We use FN and FM as legs and find MN, the hypotenuse of triangle NFM.
(FN)^2 + (FM)^2 = (MN)^2
18 + 4^2 = (MN)^2
18 + 16 = (MN)^2
(MN)^2 = 34
MN = sqrt(34)
