You want to find out how much flour she used first. In order to do that, you want to convert all your givens, into the same denominator so you can add them together.
For 2/5, multiply the top and the bottom by 2.
2/5 = 4/10 she uses for pizza.
3/10 already has the same denominator, so we can add them together.
4/10 for pizza + 3/10 for bread = 7/10 already used.
1- 7/10 = 3/10 left
Rigid mapping is used to illustrate rigid transformation.
The rigid mapping rules are:
- <em>(a) (x, y)->(y,x)
</em>
- <em>(c) (x, y)->(-y, x)
</em>
- <em>(d) (x, y)-> (-y +4, X-6)
</em>
- <em>(e) (x, y)->(x + 4, y-5)
</em>
- <em>(f) (x, y)->(x, x+y)
</em>

All transformations are rigid except dilation.
This is so, because dilation <em>changes the size </em>of the function that is being transformed, while others do not.
Dilations are represented by scale factors (<em>product or division</em>)
From the list of given options
<em>(b) (x, y)->(3x, y) and (c) (x,y)-> (3)</em> are non-rigid mapping because they represent dilations.
Hence, the rigid mapping rules are:
- <em>(a) (x, y)->(y,x)
</em>
- <em>(c) (x, y)->(-y, x)
</em>
- <em>(d) (x, y)-> (-y +4, X-6)
</em>
- <em>(e) (x, y)->(x + 4, y-5)
</em>
- <em>(f) (x, y)->(x, x+y)
</em>

Answer:y= 4x+2
Step-by-step explanation:
Percent formula : is/of = %/100
is = 187.05
of = 645
% = x
now we sub
187.05/645 = x/100
this is a proportion and we now cross multiply
645(x) = (187.05)(100)
645x = 18705
x = 18705/645
x = 29
so... 187.05 is 29% of 645
u can use the percent formula on all percent problems...just make sure u sub the numbers in the right spot.
