What you have to do first is to add and ,
Therefore we have:
= +
= ( + ) / 15 (15 is the smallest number that divide both denominator also known as LCD)
= (5 x 1) + (3 x 4) / 15
= 5 + 12 / 15
=
Therefore, the sum of + is
But since the question says you should determine the sum of the 2 fractions, therefore you should multiply by 7. Therefore you should have:
X 7 (7 can also be expressed as )
= x (notably, in multiplication there is no need for the fraction to have the same denominator. You can multiply both numbers at the top together (numerator) and do same with the denominator.
=
=
Therefore, 7 times as much as the sum of and is

Answer:
No rotation will produce a polyhedron. The solids of rotation are non-polyhedral.
Step-by-step explanation:
Solids of rotation will always have a curved face, so they’re always non-polyhedral.
In Step 1, the radius should be found by multiplying the diameter by 2.
In Step 2, the formula 2pi r should be used to find the area of the circle.
In Step 3, the resulting area should be in terms of pi
In Step 4, the units of the resulting volume should be cm^2
Whenever we are given with the diameter of any such figure ,
to find the radius , we divide the diameter by 2.
We know that
Diameter = 2 * radius
or
Radius = Diameter /2
,
In the question it says the in first step that
the radius should be found by multiplying the diameter by 2
, this is the first error
It should be that
the radius should be found by dividing the diameter by 2

Answer:
y = 0.5x
Step-by-step explanation:
x = 1; y = 0.5; 0,5 is of 1
1 * 0.5 would equal 0.5
So, y = 0.5x
Hope this helps :)
