Step-by-step explanation:
Srectangle=21*30=630cm^2
Ssemicircle=(11.5^2*pi)/2=132.25pi/2=66.125cm^2*pi
Sfigure=630cm*2+2*66.125cm^2*pi=630cm^2+pi*132.25pi
if we assume that pi=3.14
Sfigure=630cm^2+415.265cm^2=1045.265cm^2
Answer:
5 tokens
Step-by-step explanation:
<u><em>She spent 1 out of every 4 tokens,</em></u> meaning there are a couple of sets of 4 that we don't know many they are yet that she kept taking from every set 1 token, so if we do,
(Her total tokens) 20 ÷ 4 = 5.
This means that there's 5 sets, then we take 1 from every set so 1 × 5 = 5, that's it
I don't know if that was quite clear tho you can imagine it in a more virtual than mathematical way if you like,
Now Imagine you have 20 tokens in your hand, and you divide them into 5 sets, each set is a set of 4, you keep 3 in your hand then put 1 on a table, then you do this 5 times you'll end up with 5 tokens on the table and 15 in your hand.
<em>You can try that yourself if you want it to be more clear.</em>
Take 20 small pieces of paper, sticky notes or coins whatever you like, then divide them into sets of 4, then lastly take only 1 from each set (and by the way you'll notice that dividing each set into a set of 4 will make you automatically end up with 5 sets) now count all the 1's you collected from each set
they should be 5.
Add or Mulitaply or divoin that is really the main thing you have to do
