When someone is doing rotation, at the beginning, his arms are extended, the moment of inertia is j, and the angular velocity is w. when he retracts his arms, the moment of inertia is 3:4j, and W is obtained

Conservation of angular momentum
Jω=J1ω1
ω1=Jω/J1=Jω/（3J/4）=4ω/3=1.33ω

If a1 + A2 = 5, A3 + A4 = 9, then the value of S10 is () a. 55B. 60C. 65D. 70

In ∵ arithmetic sequence {an}, a1 + A2 = 5, A3 + A4 = 9, ∵ a1 + A1 + D = 5A1 + 2D + A1 + 3D = 9, the solution is A1 = 2, d = 1, ∵ S10 = 10 × 2 + 10 × 92 × 1 = 65

When a car runs at a speed of 36km / h, the acceleration after braking is 4m / S2
A. 0 mB. 100 mC. 12.5 mD. 37.5 m

According to v = V0 + at, the time needed to reduce the vehicle speed to zero is: t0 = V − v0a = 0 − 10 − 4S = 2.5s, that is, the vehicle stops moving after braking for 2.5s, and the displacement of the vehicle passing after 5S is equal to the displacement within 2.5s, which is x = V0 + v2t0 = 10 + 02 × 2.5m = 12.5m

Xiaoli has 12 more color pictures than Xiaolan, which is just 310 times of Xiaolan's. how many color pictures does Xiaolan have? How many do Xiao Li have?

12 △ 310 = 40 (sheets); 40 + 12 = 52 (sheets); a: Xiaolan has 40 color pictures, Xiaoli has 52

Given the line segments a, B and C (a > b), use a compass and a ruler to draw the line segment, which is equal to a + 2b-c

Draw a long line segment, take a point 1 as the center of the circle, take B as the radius, draw two points 2 and 3 intersecting with the straight line, then 2-3 is 2B; take 2 as the center of the circle, take a as the extension line of radius 3 → 1 → 2, draw point 4 intersecting with the straight line, then 2-4 is a; take 3 as the center of the circle, take C as the radius, draw between 3 → 1 → 2 → 4

A math problem in Grade 7 is a system of equations. Please help me. Thank you
It is known that the solution of the system of equations ax + by = 3 about X, y is x = 2, and the value of a + B is obtained
bx＋ay=7 y=1
Clear and correct process, thank you.

Substituting x = 2, y = 1 into the equations, we get the following results
2a+b=3
2b+a=7
Add the two formulas 3A + 3B = 10, a + B = 10 / 3

In the equal ratio sequence {an}, if the common ratio q = 2 and the sum of the first 99 terms s99 = 30, then A3 + A6 + A9 + a99=______ ．

Because {an} is an equal ratio sequence with a common ratio of 2, let A3 + A6 + A9 + +A99 = x, then a1 + A4 + A7 + +a97=x4a2+a5+a8+… +a98=x2S99=30=（a1+a4+a7+… +a97）+（a2+a5+a6+… +a98）+（a3+a6+a9+… +a99）=x+x2+x4∴a3+a6+a9+… A99 = 1207, so the answer is: 1207
