2. You bought items at Best Buy totaling $290.76. You have a 20%
vovangra [49]

Answer:

Discount = $290.76 × 0.2 = $58.15

Cost After Discount = $290.76 - $58.15 = $232.61

Sales Tax = 0.0625 × $232.61 = $14.56

How Much You Pay = $232.61 + $14.56 = $247.17

Step-by-step explanation:

Discount:

290.76 × 0.2* = 58.152

Round that to 58.15

* Turn 20% into a decimal (0.2)

Cost after Discount:

290.76 - 58.15 = 232.61

Sales Tax:

First turn 6.25 % into a decimal. Which would be 0.0625.

0.0625 × 232.61* = 14.556875

Then we round to the nearest hundredth and you get 14.56.

* We us the amount after the discount instead of the original price.

How much you pay:

232.61 + 14.56 = 247.17

Write 8/4 as a mixed number. how did you come to your answer
Sergeeva-Olga [200]
To write in the mixed fraction you have to simply divide 8 and 4. 
To right in the mixed number we need to know numerator, denominator and divisor. 
So in your problem our divisor is 4, 
so now lets divide it 
\frac{8}{4}
=  \frac{2}{1}

So, now we have to write it as mixed number..
mixed number  will be 
2  \frac{0}{8}

Hope this helped you.. :)

Need help trigonometry<br>​
pochemuha

Answer:

The measure of angle F is 67.6°

Step-by-step explanation:

In the right triangle DEF

∵ ∠E is the right angle

∵ Side DF is opposite to ∠E

∴ DF is the hypotenuse of the triangle DEF

∵ Side EF is the adjacent side of ∠F

∵ The cosine ratio = \frac{Adjacent}{Hypotenuse}

∴ cos∠F = \frac{EF}{DF}

∵ EF = 8 units

∵ DF = 21 units

→ Substitute them in the cosine ratio above

∴ cos∠F = \frac{8}{21}

→ Use cos^{-1} to find the measure of angle F

∵ m∠F = cos^{-1}(\frac{8}{21})

∴ m∠F = 67.60731219 degrees

→ Round it the nearest tenth of a degree

∴ m∠F = 67.6°

∴ The measure of angle F is 67.6°
