Answer:
Step-by-step explanation:
k = 3pw
Step 1: switch sides.
3pw = k
Step 2: Since you want w alone, and w is being multiplied by 3p, divide both sides by 3p.
What you can do is multiply the whole first equation by 12, so 6x + 26.4y = 108.
then since the coefficients of the x value (the number in front of the x) are the same in both equations, you can subtract the second equation from the first:
6x + 26.4y = 108
-(6x + 0.4y = -22)
26y = 130 divide by 26
y = 5
you can then plug y=5 into one of the equations to solve for x:
0.5x + 2.2(5) = 9
0.5x + 11 = 9 subtract 11 from both sides
0.5x = -2 multiply each side by 2
x = -4
In the given question it is given that , AC = 105 yd, BC = 60 yd and angle ACB= 69.3 degree.
We have to find the distance of AB, and for that we use law of cosine, which is
Substituting the values of AC, BC and theta, we will get
Answer: 1 in 13
Step-by-step explanation:
Yes
Answer:
Sources of electrical current
Step-by-step explanation:
Based on the information given the reason why
He/ She places a compass at different positions on a wall until the compass needle change to a direction was because the construction worker
was most likely using the compass to find the Sources of an ELECTRICAL CURRENT or where the ELECTRICAL CURRENT originated from reason been that ELECTRICAL CURRENT is the movement of electric charge from cathode to anode .
