6 feet long cast shadow = 24 feet pole
18 feet long cast shadow = 72 feet pole
18/6=3
24x3=72
(1, 3.5 ) and (3, 3.5 )
the endpoints of the midsegment are at the midpoints of DE and DF
using the midpoint formula with D(0, 7), E(2, 0), F(6, 0)
midpoint of DE = [
(0 + 2),
(7 + 0)] = (1, 3.5)
midpoint of DF = [
(0 + 6),
(7 + 0)] = (3, 3.5)
Answer:
9 weeks ,1kg is equal to 1000grams so 109kg minus 9kg is equal to 100kg
Let's callx = number of dimes.y = number of nickels.We must make a system of two equations with two incgonitas to solve the problem and find the solution, knowing that we have 50 coins and that between both they add $ 4.50.The result is x = 40, y = 10.I attach the solution to the problem.
Answer:
A = 75 units²
Step-by-step explanation:
6-8-10 triangle so PL = 10
For left triangle
6/8 = PM/10
PM = 60/8 = 7.5
A = PL•PM = 7.5(10) = 75
