Answer: i'm pretty sure Meg would have skated 1/2 of a mile in an hour
CHECK THE ATTACHED FIQURE FOR THE BRIDGE
Answer:
60 ft
Step-by-step explanation:
From the question we know that triangles ABC and EDC are in a 1:1 with this given ratio it implies that
triangles ABC and EDC are congruent then we can say
side EC = side AC
3x + 9 = 5x - 5
Then we can simplify to know value of x
3x + 14= 5x
2x = 14
x = 7
But we know that AC= 5x - 5 , then substitute value of x into it
AC = 5x + 5 = 5(7) - 5
= 35 - 5
AC= 30 ft
Also EC= 3x + 9 then substitute value of x into it
EC = 3x + 9 = 3(7) + 9
= 21 + 9
EC= 30 ft
Then the the distance between the top and bottom of the bridge, in feet, = EC+AC
= 30 + 30 = 60 ft
Answer:
4.5 minutes
Step-by-step explanation:
first convert 3/4 to a decimal so you can multiply it which would be .75
so then .75 times 6=
4.5
Answer:
use the formula (n-2)×180° where 'n' equals the number of sides the polygon has and this will be the total of all interior angles; if the polygon is 'regular' then you can find each angle measure by dividing total degrees by the number of sides
