Answer:
20, 24
Step-by-step explanation:
smaller: x
larger: 2x - 16
x + 2x - 16 = 44
3x -16 = 44
3x = 60
x = 20
smaller: x = 20
larger: 2x - 16 = 2(20) - 16 = 24
Answer:
Step-by-step explanation:
The area of a triangle is
A=bh/2 where b=base dimension and h=height
1) 10(12)/2=60mm^2
2) 14(34)/2=238in^2
3) 9.5(19.25)/2=91.4375yd^2
4) 4.9(23.7)/2=232.26m^2
5) 285=15b/2, 15b=578, b=38ft
6) 17h/2=18.7, 17h=37.4, h=2.2cm
7) 12.25b/2=128.625, 12.25b=257.25, b=21in
Step-by-step explanation:
The ratio of the perimeters = the scale
P₂ / P₁ = 6 / 4 = 3 / 2
The ratio of the areas = the square of the scale
A₂ / A₁ = (6 / 4)² = (3 / 2)² = 9 / 4
Same for the triangles:
P₂ / P₁ = 6 / 3 = 2
A₂ / A₁ = (6 / 3)² = (2)² = 4
I believe what you are looking for is... 9.5/.2= 47.5
