Approximate and significant numbers of rational numbers, The charge of a taxi is 10 yuan when the distance s is less than or equal to 4 km. When the distance s is less than or equal to 15 km, 1.6 yuan will be charged for every 1000 meters and 2.4 yuan for every kilometer. If the distance is less than 1 km, it will be calculated as 1 km. If someone takes this kind of taxi for 14.5 km, it will be RMB yuan. If someone takes this kind of taxi, he will pay 75.6 yuan, The maximum distance is? Km I have to hand in my homework at five

"1.6 yuan per thousand meters, 2.4 yuan per kilometer,"?
14.5 -4 = 10.5
10.5, etc
11* 1.6 = 17.6
17.6 +10 = 27.6

Approximate numbers and significant numbers 3604985 take approximate numbers and keep three significant numbers. What is the result?

C. The sixth power of 3.6 × 10
D. The sixth power of 3.60 × 10

D

The approximate number 35.0 is a number accurate to -, and its significant number is

The approximate number 35.0 is a number accurate to 10 bits, and its significant digits are 3,5,0

If the coefficient is - 1 / 2 and only contains the letters X and y, the quintic monomials have____ individual

If the coefficient is - 1 / 2 and only contains the letters X and y, the quintic monomials have__ 4__ individual

The coefficient is - 3, and there are four monomials with the letters X and y, respectively

3
-3XY＾3
-3X＾2Y＾2
-3X＾3Y

Write a quartic monomial with a coefficient of - 3 and the letters X and y______ (just write one)

The qualified monomial can be - 3x2y2 (the answer is not unique), so the answer is: - 3x2y2 (the answer is not unique)

At the same time, they all contain letters a, B, C, and the coefficient is 1
A. 4 B. 12 C. 15 D. 25
