Rationalize denominator in order to vanish radical term from denominator,

\frac{7(5+ \sqrt{3})}{(5- \sqrt{3})(5+ \sqrt{3})} =  \frac{7(5+ \sqrt{3}) }{25-3} =  \frac{35+7 \sqrt{3} }{22}

Shang has a coupon for 15% off he decided to buy a shirt for 16.95 the sales tax rate is 6% what is his final cost
kati45 [8]

Answer:

After the coupon and sales tax were applied, he paid $15.27 for the shirt.

Step-by-step explanation:

We are given that a shirt is $16.95. This is reduced by 15% due to the coupon.

100\% - 15\% = 85\%

Therefore, 85% of the shirt price is still active.

\displaystyle \frac{85}{100}=0.85

We can multiply this value by the shirt price to find the current price.

16.95 \times 0.85 = 14.4075 \approx \$14.41

However, the shirt also has a sales tax of 6% applied after the coupon.

\displaystyle \frac{6}{100} = 0.06a

Now, we need to find the total price for the shirt.

\displaystyle 14.41 \times 1.06 = 15.2746 \approx \$15.27

Therefore, he paid $15.27 for the shirt.

There are 24 children in a class, 16 brown-haired and 8 black-haired. Two students are randomly selected for a stage performance
Natali5045456 [20]
The answer is 7/69.

There are 8 black-haired children among 24 children. The probability of <span>randomly selecting black haired children for the first time is:
P1 = 8/24 = 1/3

Now, there are 7 black-haired children left among 23 children. The probability of </span>randomly selecting black haired children for the second time is:
P2 = 7/23

Since we want both of these events to occur together, we will multiply their probabilities:
P = P1 * P2 = 1/3 * 7/23 = 7/69

How would you convince a fellow student hat the number 0.57 is a rational number
Pavlova-9 [17]

Start by proving to them that the number 0.57 can be converted into a fraction . A whole number can't exactly be put in to a fraction. 0.57 can be converted to 14.25/25. This information means that 0.57 IS a rational number. Hope this convinced them!
