Answer:
$4.71
Step-by-step explanation:
you would multiply the radius times pi (you would get 6.42 ft) and then divide that by 1.35 (simplifying it to 642 divided by 135 and you would then get 4.706...)which rounds to the answer
Answer:
y=2
Step-by-step explanation:
first solve those in the brackets then find the square root
2y+3=11
put like terms together
3 goes to the right side
2y=11-3
2=8
y=4
√4=2
y=2
Answer:
The correct options are;
1) The shape maps unto itself after a rotation of 270 degrees
2) The smallest angle of rotational symmetry is 90 degrees
3) The shape maps unto itself after a rotation of 180 degrees
Step-by-step explanation:
We note that the shape of a cross which consists of two equal members (segments) bisecting each other at right angles such that when a member is placed vertically upright, the other member will be horizontal, therefore we have;
After rotation by 90 degrees, the vertical member will become horizontal and vice versa
After rotation by 180 degrees, the vertical member will become horizontal and vice versa again
Similarly, after rotation by 270 degrees, the once vertical member will become horizontal and the horizontal member will become vertical
Answer:
C
Step-by-step explanation:
8 divided by 9 = 0.8888...
Given that the diameter of a human hair 
Given that the diameter of a spider's silk 
Now we have to find how much greater is the diameter of a human hair than the diameter of a spider's silk.
To find that we just need to subtract the given numbers.
Since powers are not same so let's make them equal
now we can easily subtract the coefficients that is 3 from 9
Hence final answer is 
.
