Write the characteristic (state) equation of the falling edge triggered edge JK Trigger?

The characteristic equation of JK flip flop: QN + 1 = inverse of J * QN + inverse of K * QN
Master slave JK flip-flop, edge JK flip-flop and edge D flip-flop belong to the category of pulse unit circuit

A cone-shaped sand pile with a radius of 3 m. pour the pile of sand into a rectangular sand pond with a length of 4 m and a width of 3 m. how thick is the sand in the sand pond?
I hope you can help me now

Listen to mother Wang Zulan,
(3.14 × 3 × 3 × 2 × 1 / 3) / (4 × 3) = 1.57 (m)

I'd like to know how much does 320 divided by 4 and then divided by 6 equal 13

320/4=80
80 / 6 = 13 more than 2

If S3 = 6, a7 + A8 + A9 = 24, then s99 =?

an = a1+(n-1)d
S3= (a1+d)3 = 6 (1)
a7+a8+a9 = 3a1+21d =24 (2)
(2)-(1)
d = 1
a1= 1
S99 = ( a1+49d)99 = 50(99) = 4950

2 / 3 + 2 / 15 + 2 / 35 + 2 / 63 + 2 / 99

2 / 3 + 2 / 15 + 2 / 35 + 2 / 63 + 2 / 99
=1-1/3+1/3-1/5+1/5-1/7+1/7-1/9+1/9-1/11
=1-1/11
=10/11

Q: what is the solution set of inequality (square of M + 1) x > 3
Inequality of degree one variable

M²+1>0,
So x > 3 / (M & # 178; + 1)

What is 8 / 15-2 / 9 + 13 / 36?

6/6+13/36

To solve the equations: (1) 3x + 4Y = 11,2x + 3Y = 8 (2) (x + 2) / 3 + (Y-1) / 2 = 2 is a fast process
The second question is (x + 2) / 3 + (Y-1) / 2 = 2, 3x-2y + 3 = 0

1. 3x + 4Y = 11... (1) 2x + 3Y = 8. (2) (1) * 2 - (2) * 3 get: 8y-9y = 22-24, so y = 2, substituting (2) get: 2x + 6 = 8, that is, x = 1.2, two sides of the former multiply by 6 to get: 2 (x + 2) + 3 (Y-1) = 12, that is: 2x + 3Y = 11. (1) 3x-2y = - 3. (2) (1) * 3 - (2) * 2 get: 9y - (4Y) = 33 - (- 6) 13y = 39

What's 270 times 2 / 9
Please be more detailed

270*2/9
The denominator is 1 and the numerator is 3,
Multiply 3 and 2 to get the answer 60
or
First, multiply 270 and 2, and divide them into 9 points to get the answer of 60

The ratio of the three sides of a triangle is 4:5:6, and the circumference is 45cm

Let the three sides be: 4K, 5K, 6K;; then the circumference = 45 = 4K + 5K + 6K = 15K;
K = 3, so the lengths of the three sides are 12cm, 15cm and 18cm respectively
