Answer:

0.4

Step-by-step explanation:

x=\frac{d}{2} =\frac{2.4}{2}  =1.2\\

p=\frac{x^{2} }{4y}

p=\frac{(1.2)^{2} }{4(0.9)}

p=0.4

What is the sum of 3/10 and 17/100
alina1380 [7]
3/10 + 17/100

first make the 10 of the 3/10 turn into a 100 so it will make the 100 of the 17/100.
to make 10 turn into a 100 you multiply it by 10. if you're going to multiply the bottom number by 10 then you have to do the same thing with the top number:
3/10 * 10/10
3*10=30
10*10=100

new equation:
30/100 + 17/100

now just add the top numbers and leave the 100's alone:
<span>30/100 + 17/100
</span>30+17=47
<span>30/100 + 17/100 = 47/100</span>
