Answer:
Step-by-step explanation:
The formula of a surface area of a cylinder:
r - radius
H - height
We have r = 40mm and H = 50mm. Substitute:
Answer:
59/100
Step-by-step explanation:
2*25+5+4=59
1) Convert mixed fractions into fractions.
6 2/5 = ((6*5) + 2) / 5 = 32 / 5
2 2/3 = ((2*3) + 2) / 3 = 8 / 3
2) 32 / 5 ÷ 8 / 3 ; where 32/5 is the 1st fraction and 8/3 is the 2nd fraction
a) Get the reciprocal of the 2nd fraction:
From 8/3 to 3/8
b) Multiply 1st fraction to the reciprocal of the 2nd fraction
32 / 5 * 3 / 8 = (32*3) / (5*8) = 96 / 40
c) Simplify the fraction.
96 / 40 divide by 4 will become 24/10.
24 / 10 divide by 2 will become 12 / 5. The simplified fraction of 96/40.
The unit rate is 12 / 5 = 2 2/5 revolutions per second.

The lower quartile is quartile 1. The graph shows it as "-4". So the answer is D.
Answer:
x=0 , y=0
Step-by-step explanation:
2x +6y= 8 .....eqn 1
4x +12y= 16....eqn2
we multiply eqn 1 by 2.. because we want at least one variable to have the same coefficient so we can simply.
2x +6y =8... ×2
will give you 4x +12y = 16....eqn 3
so now we subtract eqn 2 from eqn 3
4x + 12y= 16
- 4x + 12y = 16
_____________
0 + 0 = 0
therefore x = 0 and y= 0
