The cake store is having a 25\%25% off sale on all of its cakes. if the cake you want regularly costs \$9$9, how much would you save with the discount?

You would save $2.25.  

Step-by-step explanation:

In order to find discount on an item, you need to multiply the discount by the original amount of the item.  In this case, the cake you want regularly costs $9.  If the sale includes a 25% discount, then you need to first convert your percentage to a decimal by dividing by 100:

You can then take this amount multiplied by the original cost of the cake to get your discount:

0.25 x 9 = 2.25, so you would save $2.25 with the discount and pay only $6.75 for the cake you want.  

step-by-step explanation:

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.
