Answer:
1. 31
Step-by-step explanation:
a² + 8² = 32² (<em>figure out what 8² and 32² equal</em>)
a² + 64 = 1024 (<em>subtract 1024 - 64</em>)
a² = 960 (<em>find the square root of 960</em>)
√960 = 30.98 = 31 (<em>round to the nearest whole number</em>)
Step-by-step explanation:
Volume =pir^h
V1=pi r1^h
V2=pir2^2h
Now,V1/V2=r1^2/r2^2
v1/v2=r1^2/(1.05)^2 ((r2=r1+5/100r1)
v1/v2=1/1.1025
v1/v2=0.907
(v1/v2-1)=0.0907×100%
(v1-v2)/v2=9.07%
increase in volume is 9.07%
The answer is 42! hope this helps!
X=9 -12 divided by -4 is -3, so you get -3x=-27. When you divide -27 by -3 you get positive 9. Thus making X=9
