hopefully this is correct..
it's either e = 1/3 or 3
The percent of change will be a percentage increase because we go from a smaller number to a larger number. To find a percentage increase, we will use the percentage increase formula:
% increase = final value - original value / original value x 100
Substituting the values in:
% increase = (8,200) - (7,500) / 7,500 x 100, where 8,200 is the new value and 7,500 is the original value.
Simplification after multiplication: 700 / 7,500 x 100
Simplification after division: 0.093 x 100
Simplification after multiplication of 100: 9.333%.
We can round 9.333% down to 9%.
She can write 3/8 of a page in 1 minute.
basically, she writes 1/8 of page in 1/3 of a minute. So, that means she can write 1/4 of a page in 2/3 of a minute.
1/4 + 1/8 = 3/8.
I really hope this makes sense to you.......sorry I'm not that great at explaining it.
The new triangle is gonna be bigger. But how big? Let’s look at A.
A= 2,8
Look at A’, it’s 6,24. See a pattern??
Multiply 2,8 by 3. It’s triple the amount, therefore the scale factor is 3.
To double check, multiply by 3 to B and C and see what you get.
The answer would be C. the new weight room as an area of 520 ft.
I hope I've helped!
