Answer:
d=−bc+a/0.5bc
Step-by-step explanation:
Let's solve for d.
a=0.5bcd+bc
Step 1: Flip the equation.
0.5bcd+bc=a
Step 2: Add -bc to both sides.
0.5bcd+bc+−bc=a+−bc
0.5bcd=−bc+a
Step 3: Divide both sides by 0.5bc.
0.5bcd/0.5bc = −bc+a/0.5bc
d=−bc+a/0.5bc
The probability of a dime is 66% or 2 in 3 or 2:1
Answer:
I think it is 4:3
Step-by-step explanation:
From $960,000 take away $720,000 and you get $240,000 and that $960,000 divide by $240,000 and you get 4 and you do the same with $720,000 and you get 3
Answer:
Step-by-step explanation:
Given: The radius of circle O is r, and the radius of circle X is r'.
To prove: Circle O is similar to circle X.
Proof: Move the center of the smaller circle onto the center of the largest circle. Translate the circle X by the vector XA onto circle O. The circles now have the same center.
A dilation is needed to increase the size of circle X to coincide with the circle O. A value which when multiplied by r' will create r.
The scale factor x to increase X:
⇒
A translation followed by a dilation with scale factor will map one circle to the other, thus proving the given both circles similar.
Therefore, circle O is similar to circle X.
