Answer:
2.46×10^8
Step-by-step explanation:
The decimal point is here
246000000.
Then it must be moved up to here
2.46000000
Those are eight steps from where it was, so to compensate and make sure the number remains the same remove the zeros and multiply by 10^8
Then you have
2.46×10^8
2x - 2y = 12
-2x - 3y = -22
solution could be (x,2)
===============
2x - 6y = 10
x + 8y = 5
solution could be : (5,y)
==============
3x - y = -5
x + 4y = 7
solution could be : (x,2)
=============
x + y = 2
2x + y = 13
solution could be : neither....is this one written correctly ?
Answer:
69% to a simplified fraction is 69/100
Answer:
The answer is : 23.25 in ²
Step-by-step explanation:
There are 3 triangles with the same lengths: height = 5in and base = 5 in
There is one triangle: height = 4.3 in base = 5 in
Formula
Area = height x base / 2
For the triangles
Area = 5 in x 5 in /2 = 25 /2 = 12.5 in²
For the triangle
Area = 4.3 x 5 /2 = 21.5 /2 = 10.75 in²
Total surface area = 12.5 + 10.75 = 23.25 in²
