A drinking glass is shaped like a cylinder with a height of 5 in. and a diameter of 3 in. Maeva adds 25 spherical pieces of ice to the glass. The pieces of ice each have a diameter of 1.1 in.How many cubic inches of water can Maeva add to fill the glass to the rim? Use 3.14 to approximate pi and round your answer to one decimal place.
Answers
Answer 1
Answer:
first find volume of glass find volume of ice subtract
cylinder area=height times are of base
height=5 area of base=circle=pi times radius^2 diameter=2radius diameter/2=radius 3/2=radius=1.5
pi=aprox 3.14 3.14 times 1.5^2=7.065 7.065 times 5=35.325=volume of glass
25 spereical ice volume of shqere=4/3 times pi timers r^3 diameter/2=r 1.1/2=0.55 4/3 times 3.14 times 0.55^3=0.696557=1 ice multiply by 25 17.4139 subtract 35.325-17.4139=17.9111 round to one decimal place 17.9
Describe the pattern in the equation. Then solve the equation.0.3x + 0.03x + 0.003x + 0.0003x + ....= 3

The answer is 'D'
When you divide 48 and 78 by 2, you get 24 and 39. Then divide 24 and 39 by 3 and you will get 8 and 13, which don't have any common factors.
The same happens with 12 and 30... When 12 and 30 are divided by 2, you get 6 and 15. Then divide 6 and 15 by 3 and you get 2 and 5, which have no more common factors.

John will be x in 7 years. How old was he last year? A: x + 7 B: 1 - x - 7 C: x + 8 D: x - 8
Answers
Right now, he is 7 less than he will be in 7 years, and 1 more than he was last year.
'x' is 7 more than he is right now, and 8 more than he was last year.
If 'x' is 8 more than he was last year, then he was (x - 8) last year.
That's Choice-'D'.
D is the answer, because seven minus X is his age this year and a year before that is last year. So the answer is X-8
