A and B start from AB and run in opposite directions at the same time. A runs 6 kilometers per hour and B 8 kilometers per hour. They meet at 32 kilometers away from the midpoint, and the distance between them is very long

A speed: B speed = 6:8 = 3:4
Time is fixed, speed ratio = distance ratio = 3 ∶ 4
A made 3 / 7 of the whole journey
B did 4 / 7 of the whole journey
The whole process = 32 × 2 ^ (4 / 7-3 / 7)
=64×7
=448 km

1/2 -1/4 1/8 -1/16 1/32 …
The nth number is
The 25th number is

1/2 -1/4 1/8 -1/16 1/32
It's positive and negative. It's odd positive and even negative
Look at the size again, look at denominators 2, 4, 8, 16, 32
In fact, they are all to the power of 2 2 ^ 1 2 ^ 2 2 ^ 3 2 ^ 4 2 ^ 5.2 ^ n
So, the nth number is
-（-1/2)^n
The 25th number is
-（-1/2)^n
=-（-1/2)^25
=1/2^25

On a map with a scale of 1:5000000, the distance between a and B is 4cm
Q: how many centimeters should we draw? The solution of the equation

If x cm should be drawn, then
5000000：X=2000000：4
2000000X=5000000×4
2X=20
X=10
A: 10 cm should be drawn on a map with a scale of 1:2000000

Let non-zero real numbers a, B, C satisfy the square of (a-b) - 4 (B-C) (C-A), find the value of a + B / C, and write out the calculation process

The title is incomplete. You can see it again

Number a is 58% of number B, and number B is more than number a______ %．

(1-58%) / 58% = 42% / 58% ≈ 72.4% answer: number B is 72.4% more than number a
