Answer:
0.24 and 1.32
Step-by-step explanation:
you divide 2.28 by 9.5 for the first answer then multiply that answer by 5.5
Answer:
The sides of ∆ABC are 30 units, 40 units, and 60 units long.
The perimeter will be =
units
Given is that ∆ABC and ∆XYZ are similar and the corresponding sides of ∆XYZ are 'r' times as long as the sides of ∆ABC.
So, perimeter of ∆XYZ will be :
units.
----------------------------------------------------------------------------------------
The area of ∆ABC is n square units, so area of ∆XYZ will be :

= 
=
square units.
Speed of truck= x
speed of train=x-30
A loaded moving truck is traveling 30 mph faster than a freight train. in the time it takes the train to travel 135 miles, the truck travels 225 miles. find the speed of the truck.
A loaded moving truck is traveling 30 mph faster than a freight train...
(x-30)=speed of train
the time it takes the train to travel 135 miles, the truck travels 225 miles...
135/(x-30)=225/x
the you multiply on both sides the x values and get...
135x=225x-6750
then you subtract 225x on both sides...
-90x=-6750
then you divide -90 on both sides...
x=75
the speed of the truck is 75mph
i hope this helped give me a thanks and a 5 star rating if it helped! c:
