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.
60% decrease
15 is 60% of 25
What is 60% of 25?
Y is 60% of 25
Equation: Y = P% * X
Solving our equation for Y
Y = P% * X
Y = 60% * 25
Converting percent to decimal:
p = 60%/100 = 0.6
Y = 0.6 * 25
Y = 15
Answer:
23 cm
Step-by-step explanation:
575/25=23
First answer haha~ I think I answered all your questions so far ;)
1, 2, 4, 8, ..., 128
In that sequence, each term is getting multiplied by 2.
1
1x 2 = 2
2 x 2 = 4
4 x 2 = 8
So, if we keep multiplying until we reach 128, the sequence 1, 2, 4, 8 would continued with:
8 x 2 = 16
16 x 2 = 32
32 x 2 = 64
64 x 2 = 128
So this means that the missing terms are:
16, 32, 64
This makes the whole sequence:
1, 2, 4, 8, 16, 32, 64, 132
