Answer:
its simple just divide the value whole piece by the value of Cutted pieces
Step-by-step explanation:
we get
4.5 ÷ 0.75
= 6
means there are 6 pieces
hope it helps
have a nice day : )
Answer:
<u>5/6 ÷ 7/10 = 1 4/21</u>
Step-by-step explanation:
<u>How did we solve the problem above? When we divide two fractions, such as 5/6 ÷ 7/10, we flip the second fraction and then we simply multiply the numerators with each other and the denominator with each other.</u>
<u>We also simplify the answers to fraction problems whenever possible. hope this helps</u>
The circumference (perimeter) of the tire is 2 x π x r (radius= half of the diameter):
So one complete rotation is equivalent to the perimeter that is 2 x 13 x 3.1459
= 81.68 inches & if he competed 10 rotation that means he run for 10 x 81.68 ===> 816.8 In
The heat produced by current I is
H = I²R
where
R = resistance.
According to the formula, heat produced is proportional to the square of the current.
When a current of I = 2 amps is applied, the heat produced is
H = 10x³ + 80.
This heat includes heat due to a fixed current of 2 amps, and heat due to a variable current of x amps.
Because the heat produced is proportional to the square of the current, write the expressions as
H = (10x)*(x²) + 20*(2²)
The second term on the right is heat due to the fixed current of 2 amps, written as
20*(2²).
Therefore the fixed resistance is R = 20 ohms, and the square of the fixed current is 2².
The first term represents heat due to variable resistance, written as
(10x)*(x²).
Therefore the variable resistance is 10x, and the square of the variable current is x².
Answer:
The variable current is 10x.
