likoan [24]

Set up an equation to solve for the tax rate, x:

350(x) = 22.75\\x = \frac{22.75}{350}\\x = 0.065\\x = 6.5%


We can conclude that the tax rate on the computer was 6.5 percent.

in the afternoon the temperature was 52 f. A strong arctic cold front caused the temperature to drop to 38 degrees in 4 3/4 hour
Reika [66]

Answer: 32 2/19°F

Step-by-step explanation:

Since the temperature was 52° and dropped to 38°, the difference will be:

= 52° - 38°

= 14°

Therefore, 14° was dropped in 4¾ hours. Therefore, the temperature dropped pee hour will be:

= 14/4¾

= 14 / 19/4

= 14 × 4/19

= 56/19

= 2 18/19° per hour.

In 2 hours, the temperature dropped will be:

= 2 18/19° × 2

= 5 17/19°

With the above explanation, the temperature after 2 hours will then be:

= 38° - 5 17/19°

= 32 2/19°F

The temperature will be 32 2/19°F.
