a = 5 in
b = 12 in
c = 15 in
the lengths of the sides a, b and c
the perimeter is P = a + b + c = 5 + 12 + 15 = 32 in
let the dimensions of the new triangle be
a1 = (1/5)*5 in
b1 = (1/5)*12 in
c1 = (1/5)*15 in
the perimeter is P1 = a1 + b1 + c1 = (1/5)5 + (1/5)12 + (1/5)15 = (1/5)(5 + 12 + 15) = (1/5)P1
P1 = (1/5)P
P1/P = 1/5 = a/a1 = b/b1 = c/c1
the ratio of the perimeters is equal to the ratio of the corresponding sides.
Answer:
Step-by-step explanation:
height h=1.2 m
radius r= D/2=4.5=2.25 m
Volume V=πr²h=π(2.25)²×1.2 ≈3.18m³
Answer:
The answer to your question is y = x - 23
Step-by-step explanation:
Process
1.- Get the slope of the line
If two lines are parallels, it means that they have the same slope.
y = 1x - 10
Slope = m = 1
2.- Get the equation of the line
y - y1 = m(x - x1)
y + 29 = 1(x + 6) Substitution
y + 29 = x + 6 Expanding
y = x + 6 - 29 Simplifying
y = x - 23
