Answer:
79/8
Step-by-step explanation:
19 3/4 = 79/4
79/4 / 2 is same as 79/4 * 1/2
79/8
Answer: 79/8
It will be easier to explain how to solve this question in a square. If you rotate 4-sided square from the centre, you need to rotate it 90 degrees. The formula for this would be: 360 ° /the side count. In a square, it would be 360° /4= 90°.
In 18-sided polygon, the calculation would be: 360°/ 18 side= 20°
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.
It will be 48/52 because there are 4 kings so 52-4=48
