Answer:
It is three times as large
Step-by-step explanation:
If a ration is also a fraction, and your wording is correct than an enlargement of 1:3 where 1 is the original shape would suggest that the 3 would be that same original shape, be enlarged in terms of 3 compares to 1 so a 300% enlargement.
if the original rectangle has a 16 cm perimeter, than the new rectangle has a 48 cm perimeter.
Answer:
33
Step-by-step explanation:
Since 31 + 32 + 33 + 34 = 130 and they are consecutive.
Original volume = 2.5 million liters.
After evaporation, the remaining volume is 2 million liters, therefore
Evaporated volume = 2.5 - 2 = 0.5 million liters.
Percent of water evaporated = 100*(0.5/2.5) = 20%
Answer: 20%
Isolate the variable by subtracting the 10 from Both sides...
You are then left with
2x=10
Then divide both sides by 2 (to isolate the variable)
Therefore
X=5
Answer:
Possible coordinate of F are (10,5) and (6,11)
Step-by-step explanation:
Coordinates A (1, 2), B (3, 2) and C (3, 5) are connected to form ΔABC
First we plot the points on coordinate plane and then draw triangle ABC. Please see the attachment for figure.
If ΔDFE is similar to ΔABC then their corresponding sides are in proportional.
Using distance formula, 
We can see ABC is right angle triangle. So, DEF must be right angle triangle because ΔDFE ~ ΔABC
Thus, Possible coordinate of F are (10,5) and (6,11)
