A 12-pack of cinnamon-scented pencils sells for $3.00 at a school booster club sale. What is the sales tax rate if the total cost of the pencils is $3.21? **The difference between the cost of $3.00 and the TOTAL at the till of $3.21 is the taxi of $0.21. So the problem is What Percent of $3.00 is $0.21? Solve it that way. Make sure to move your decimal point two places to the right for a percent answer. ***

15% chance.

step-by-step explanation:

3/10 times, the 5 year old will get a tablet. 5/10 times, the 13 yer old will get a tablet. multiply both fractions to get 15/100 times, both would have a tablet.

what shape is

false

step-by-step explanation:

the reason i say this is because for a certain length of sides you can pick any two and the length is wither equal or greater than the third side and in this case it's not.

3 + 5 = 8

8 is smaller than 9 which is the third side.

hope this : )

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
