Answer:
1.78
Step-by-step explanation:
To solve for x we need to cross multiply it
We have = sign inbetween the fractions so we cross multiply it
9*x = 2* 8
9x = 16
Now we divide by 9 on both sides
so x= 1.7777777778
When we round to two decimal places then
x= 1.78
Answer:
The candle will not use all the paraffin from the original block.
Step-by-step explanation:
The cone-shaped candle is 5 cm wide at the base i.e. the diameter of the base is 5 cm i.e. radius is 2.5 cm.
If the height of the cone is 25 cm, then total volume of the cone shaped candle is
=
= 163.69 cubic cm.
Again, the volumes of the rectangular block of paraffin is (4 × 8 × 6) = 192 cubic cm.
Since, 192 > 163.69
Therefore, the candle will not use all the paraffin from the original block.
