15 people
8 older than 30
9 have facial hair
over 30 and facial hair= 5/15
5/15= 33.3%
Answer:
350 + 30W = S
Step-by-step explanation:
Since (W) represents the number of weeks he's saving money, you'd replace (W) with 14.
350 + 30(14) = S
I think you should multiply 5x4=20.
Considering the area of the right triangle, it is found that Salome used a scale factor of 1/2 to go from triangle R to triangle T.
<h3>What is the area of a right triangle?</h3>
The area of a right triangle is given by half the multiplication of the lengths of it's sides.
In this figure, we have that the sides have lengths of 4 and 5 units, hence the area is given by:
A = 0.5 x 4 x 5 = 10 square units.
The area is one fourth of the area of triangle R. Since we are dealing with an area, that works in squared units, the scale factor is given by:
S = sqrt(1/4) = 1/2.
Hence Salome used a scale factor of 1/2 to go from triangle R to triangle T.
