Someone else on Brainly had the same question, he showed the work so I copied it so you can see it.
We have 48 meters.
We need to increase it by 20%.
That means we have 48 and then we increase it by 20%.
That can be expressed as:
48 + (48 * 20%)
Now, another way to write that would be:
48 * 120%
Now, 120% is nothing but 120/100. This can even be simplified to 1.2.
48 * 120%
= 48 * 1.2
= 57.6
48m increased by 20% is 57.6m<span>.</span>
Answer:
Step-by-step explanation:
your answer is A, 1/12
Answer:
m=2
b=-3
Step-by-step explanation:
standard form of the slope equation
y=mx+b
m=2
b=-3
7 Units.
8(1)+9= 17
8(2)+9=25
8(3)+9=33
33-25=7. 25-17=7
The travels you have described are:
(Middle floor) + 8 + 5 - 9 + 7 - 32
= (middle floor) + 20 - 41
= (middle floor) - 21 brought her to floor #1.
So Middle floor - 21 = 1
Add 21 to each side: Middle floor = 22
The building has (2 x middle floor) = 44 floors.
