Answer:
using imaginary numbers
Step-by-step explanation:
First way. you could round to the tens place and add. 370 + 230 about 600.
round to the nearest hundreds. 400 plus 200. about 600.
Answer:
You have to measure the sides and make sure they are the same and you shape them to look like a square
Step-by-step explanation:
Answer:
Per2 = 102.727 dm
Per1 = 123.272 dm
Step-by-step explanation:
We know that the area of similar triangles are related to the square of their perimeters.
This means that
(Per1^2)/(Per2^2) = Area1 / Area2
If we take the square root of the previous equation
(Per1)/(Per2) = 
(Per1)/(Per2) = 
(Per1)/(Per2) = 1.2
We also know that
Per1 + Per2 = 226 dm
So,
1.2*Per2 + Per2 = 226 dm
2.2*Per2 = 226 dm
Per2 = 102.727 dm
Per1 = 1.2*Per2 = 123.272 dm
Answer:
$1,500
Step-by-step explanation:
70*20 is 1,400, and 20*30 is 600. Those together make 2,000 sq. in. Multiply that by 0.75 and you get $1,500. Hope this helps!
