The length of each side is 28 cm.
the perimeter of the equilateral triangle is 48 cm. To find each side of the original triangle, you do 48/3=16cm. since the triangle dilate by 0.75, then you can just do 0.75*16=12cm. then you have to add 12 to 16 because the triangle gets bigger by 12 cm. so 16+12=28 cm.
Remember that 45%=45/100=0.45
So if the tennis player serves the ball 300 times, and 45% cannot be returned, then we can use the following expression to solve for the answer:
300*0.45=135serves
Answer: 135 serves will not be returned
It’s either b or d. Hope this helps! :)
Answer:
b
Step-by-step explanation:
Here is some answers
1. 2x+3y=1,470
-2x -2x
---------------------
3y=-2x+1,470
---- --------
3 3
------------------
y=-2x+490
2. rise
-----
run
y=-2
---
1
Find 490 and either go up 2 down 1 or down 2 up 1 either way you will get a straight line.
3. f(x)=2x+490
Don-t know how to explain this :(
I'm confused after this question
Hope this helped a little
