Answer:

$C =\frac{5}{9} (350-32) =176.67 C$

So then the 350 F degrees are equivalent to 176.67 C degrees

Step-by-step explanation:

For this case we are assuming that the temperature of interest is 350 F.

And we want to convert this into Celsius degrees. The formula provided is:

$C = \frac{5}{9} (F-32)$

This formula comes from this expression:

$F = \frac{9}{5} C +32$

And solving for C we got:

$F-32 = \frac{9}{5} C$

$C = \frac{5}{9} (F-32)$

And replacing we got:

$C =\frac{5}{9} (350-32) =176.67 C$

So then the 350 F degrees are equivalent to 176.67 C degrees

Answer:

6. Because to decrease = number × 100-% over 100(as a fraction)

which is =39.99 ×100-30% over 100

= 39.99 × 70/100

=27.993

After you take your answer from the decrease and subtract from the original price which is 39.99

39.99-27.993 *note the 39.99 has a zero at the end

the answer = 11.997 Rounded off it becomes 12
