A equivelint ratio is when u can multi or divide by both sides
Answer: 0.167
Step-by-step explanation:
This is an applied mathematics question
Resistors in parallel ⁾/R = ¹/₁₂₀ + ¹/₁₂₀ since the resistor is two 120
Therefore , resolve into fraction now yield
¹/R = 1 + 1
-------
120
= 2/120
= ¹/₆₀
Therefore, ¹/R = ¹/₆₀
Cross multiply to get R the resistance
R = 60
From formula, V = IR where I is the current
There fore making I the subject of the formula
I = V/R
= 10/60
= 0.166
= 0.167 A, A = ampere which is the unit of current.
Answer:
Equation 3
Step-by-step explanation:
An identity is, simply put, an equation that is always true. 1 = 1, 2 = 2, and x = x are all examples of identities, as there's no case in which 1 ≠ 1, 2 ≠ 2, and x ≠ x. Essentially, if we can manipulate and equation so that we end up with the same value on either side, we've found an identity. Let's run through and try to solve each of these equations to see which one fulfills that condition:
8 - (6v + 7) = -6v - 1
8 - 6v - 7 = -6v - 1
1 - 6v = -6v - 1
1 = -1
This is clearly untrue. Moving on to the next equation:
5y + 5 = 5y - 6
5 = -6
Untrue again. Solving the third:
3w + 8 - w = 4w - 2(w - 4)
2w + 8 = 4w - 2w + 8
2w + 8 = 2w + 8
If we created a new variable z = 2w + 8, we could rewrite this equation as
z = z, <em>which is always true</em>. We can stop here, as we've now found that equation 3 is an identity.
The reciprocal is the fraction flipped. so the reciprocal of 1/2 is 2/1. It's used when dividing fractions to make it multiplication, so you use the reciprocal for the second fraction.
