Answer:
Well if a story is 14-16 feet tall, then it would be about 50 floors.
Step-by-step explanation:
Each story is 14-16 feet, and if you meet in the middle (15 feet) just divide 750 by 15, you get 50.

Step-by-step explanation:
The nth term of an AP is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Given a₅ is double a₇ , then
a₁ + 4d = 2(a₁ + 6d) , that is
a₁ + 4d = 2a₁ + 12d ( subtract a₁ from both sides )
4d = a₁ + 12d ( subtract 12d from both sides )
- 8d = a₁
The sum of n terms of an AP is
= 
[ 2a₁ + (n - 1)d ] , substitute values
= 
( 2(- 8d) + 16d)
= 8.5(- 16d + 16d)
= 8.5 × 0
= 0
(number less tan 10 and more than or equal to 1) times (10^m)
0.00048=4.8 times 10^4
answer si 4.8*10^4
Some of these, I don't know how to answer. I can only give the answers to the ones I do know how to do.
16. 24 plants can be watered with this can.
Equation & Answer:
134.4 ÷ 5.6 = 24
17. 32 miniature bottles can be made from the large bottle of ketchup.
Equation & Answer:
198.4 ÷ 6.2 = 32
20. -3 + -8 = -11
-3 + 8 = 5
3 + -8 = -5
-9 + 4 = -5
-6 + -1 = -7
-8 + 9 = 1
Negatives plus negatives:
When there are two negative numbers together and the equation has + sign in it, the + sign changes to be a - sign.
21. 42 + -56 = -14
22. -49 + -17 = -66
Hope this helped in some way,
