A^2 + b^2 = c^2...a and b are the legs and c is the hypotenuse
20^2 + 21^2 = c^2
400 + 441 = c^2
841 = c^2
sqrt 841 = c
29 = c <== third straw will be 29 cm

Tiffany buys a basket of watermelons on sale for \$9$9dollar sign, 9 before tax. The sales tax is 9\%9%9, percent.
Gnoma [55]

Answer:

<em>Tiffany pays a total price of $9.81 for the basket of watermelons</em>

Step-by-step explanation:

<u>Percentages</u>

To increase a certain amount by a given percentage, we can first calculate the increasing amount and then add it to the original amount.

If the price of the basket of watermelons was $9 before tax, and the sales tax is 9%, we first calculate the tax amount to pay:

$9 * 9 / 100 = $0.81

Now we add it to $9 to get the total price paid by Tiffany:

Total price = $9 + $0.81 = $9.81

Tiffany pays a total price of $9.81 for the basket of watermelons

916...the 9 is in the hundreds place so its value is 900
791...the 9 is in the tens place so its value is 90

900/90 = 10
so the 9 in 916 is 10 times bigger then the 9 in 791
