Baseball hat is on sale for 15% off, which is $2.70. How much does the baseball hat cost at full price?
lidiya [134]

Answer:

27.9 dollars

Step-by-step explanation:

2.70= 15 percent

2.70x2=5.4=30 percent

5.4+2.70=8.1=45 percent

8.1x2=16.2=95 percent

95 percent + 15 percent=18.9

18.9=105 percent

in order to subtract 5 percent we need to find 5 percent by dividing 2.70 by 3

which = .9

18.9+9=27.9

100 percent is 27.9 dollars

show two ways that four people can share a 6 segment chewy fruit worm in each case how many segments does each person gets
Novay_Z [31]
<span>You can share a 6 segment chewy fruit worm by giving the four people 1 ¼ segments. Also, there are a lot ways on how to divide it equally, but in this case, I’ll show two. Here are the two ways on how to share it:

1. You can divide the worm by giving one segment for each and then divide the remaining two segments in halves, thus resulting to having </span><span>1 </span>¼ shares.
2. Cut the worm in a horizontal manner. In this way, you'll have 12 segments now. You can then proceed by distributing the share by 3s, which is still equivalent to 1 <span>¼</span>.
