1. The group of words with errors in pronunciation and form is ()
A. Praying (Q í) dumb (Y ī n) one worry can't show the thousands of peaks competing show B, peeping (PI ē) dwarfed (Zhu ō) groundbreaking listless C, supply (J ǐ) suddenly stopped (Ji á), mainstay painting mountain embroidery water D, abhorrence (Z ē ng) standing still (Ku ī) going their separate ways

Party A and Party B travel from a and B at the same time, 25 kilometers per hour for Party A and 20 kilometers per hour for Party B. they meet at the center of the two places
How many kilometers are the two places apart?
It's 15 kilometers from the center. Sorry, the wrong number

The meeting time is 15x2 / (25-20) = 6 hours
The total distance is 6x (25 + 20) = 270 km

The function y is equal to the maximum of the square of - 2 (x-3) plus 6

On a map with a scale of 1:2000000, the length of a and B is 8 cm
What's the distance between the two places

8 × 2000000 ÷ 4000000
= 16000000 ÷ 4000000
=4 cm
A: on a map with a scale of 1:4000000, it's 4cm

If a nonzero real number a and B satisfy a > b, then the following inequality holds
A.a²>b²
B.a²b>ab²
C1/a>1/b
Da/b²>b/a²

Comparison method
A A & # 178; - B & # 178; = (a-b) (a + b), because A-B > 0, the symbol is related to a + B
B A & # 178; b-ab & # 178; = AB (a-b), because A-B > 0, the sign is related to ab
C 1 / A-1 / b = (B-A) / (AB), because b-ab, so a & # 179; - B & # 179; > 0, and a & # 178; B & # 178; > 0, so D holds

The difference between a and B is 80. 3 / 5 of a equals 1 / 3 of B. what are the numbers of a and B?

Let a be x, B be y, Y-X = 803 / 5x = 1 / 3Y, and solve the equations to get x = 100, y = 180

-300 power of 2 + (- 2) 301 power=

300 power of (- 2) + (- 2) 301 power = (- 2) 300 power * [1-2] = - (- 2) 300 power = the opposite number of 2 300 power

A truck travels 58 kilometers per hour, and the speed of a car is 1.4 times that of a truck. Two cars, 904.8 kilometers apart, set out at the same time and face each other for several hours

The car goes every hour
58 × 1.4 = 81.2 (km)
Meeting needs
904.8 ÷ (58 + 81.4) = 6.5 (hours)

Party A and Party B travel from a and B at the same time, 25 kilometers per hour for Party A and 20 kilometers per hour for Party B. they meet at the center of the two places How many kilometers are the two places apart? It's 15 kilometers from the center. Sorry, the wrong number
