If the diameter is 10.5 then the radius is 5.25.
This is because the radius of a diameter is half the diameter.
So
10.5/2
= 5.25
Therefore the radius is 5.25
Step-by-step explanation:
emily: 10(5/8) = 6 1/4 or 6.25 pounds left
10- 6.25 = 3.75 used
Frances : 10(2/5) = 4 pounds left
10-4 = 6 pounds used
Bills : 10(2/5) = 4 pounds left
10-4 = 6 pounds used
add them together
15.75 or 15 3/4 pounds of soil in the first flower bed
Let S=score on the second exam, then
(67+S+(S+7))/3=84
cross multiply
2S+74=252
2S=178
S=89
So second exam: 89
third exam=89+7=96
Check: (67+89+96)/3=84 ok.
