To The bottom half it is B. 0.8(9+w) = 0.8w + 72 and 4.8 + 2.2w - 1.4w +2.4 = 0.8w + 72
Hope this helps sorry cant do other half
Given that the area of the sector is given by:
A=3.142r² S/360
where:
r is the radius
S is the angle measure of the sector
If Mia solved the equation for S, the equations that she wrote would be found as follows;
From A=3.142r² S/360
making S the subject by first dividing both sides by 3.142r^2 we shall have:
A/3.142r²=S/360
next we multiply both sides by 360
360×A/3.142r²=S/360×360
this will give us
(360A)/(3.142r²)=S
therefore the equation that Mia will get is:
S=(360A)/(3.142r²)
The smaller batch is 2/3 of the large batch so anser is2/5
