Your ratio of miniDVD to standard DVD is 2/7
Answer:
20 is 1/10 of 200.
Step-by-step explanation:
100*(1/10) = 10
200*(1/10) = 20
Since 100 times 1/10 is 10, all you have to do is double it. So now, 200 times 1/10 is 20.
:) Hope this helps!
Answer:
x = 3, y = 6
Step-by-step explanation:
In the figure attached,
If ΔADE and ΔABC are similar triangles, their corresponding sides will be in the same ratio.
By this property,
3x = 2x + 3
3x - 2x = 3
x = 3
Similarly, 
y = 
y = 6
A negative exponent means to move the decimal point to the left the number of the exponent.
10^-1 you would move the decimal 1 place to the left.
5.401 x 10^-1 = 0.5401
= x1 + x2/2 , y1 + y2/2
= 7+-1/2 , 1+(-1)/2
Midpoint = (3,0)
