Question

910000 кв см= ? кв м . реши задачу Расстояние между велосипедистами 240 м. Они выехали одновременно навстречу друг другу и встретились через 30 с . Найди скорость первого велосепедиста, если скорость второго 3 м / сек реши уравнения. Х-546=35+64 Х:6=720:2 допиши верные единицы измерения. .3...=30... 5...=5000 ... помогите контрольная на носу ничего не понимаю

Answer 1

910000кв.см=91кв.м
1)3*30=90(м)-проехал 2 велосипедист.
2)240-90=15.)- проехал 1 велосипедист.
3)150:30=5(м/с)- скорость 1 велосипедиста.


х-546=35+64
х-546=99
х=546+99
х=645
645-546=35+64
99=99
х:6=720:2
х:6=360
х=360*6
х=2160
2160:6=720:2
360=360

Answer 2

Conversion of 910000 square centimeters to square meters

To convert 910000 square centimeters to square meters, we need to divide the value by 10000 since there are 10000 square centimeters in a square meter.

Conversion: 910000 square centimeters = 910000 / 10000 square meters = 91 square meters

Therefore, 910000 square centimeters is equal to 91 square meters.

Solving the problem of the distance between two cyclists

Let's solve the problem of the distance between two cyclists who start simultaneously and meet after 30 seconds. The speed of the second cyclist is given as 3 meters per second.

Let's assume the speed of the first cyclist is represented by the variable 'v' (in meters per second).

The distance traveled by the first cyclist in 30 seconds is equal to the distance traveled by the second cyclist in the same time. We can use the formula:

Distance = Speed × Time

For the first cyclist: Distance = v × 30

For the second cyclist: Distance = 3 × 30

Since they meet at the same point, the distances traveled by both cyclists are equal. Therefore, we can set up the equation:

v × 30 = 3 × 30

Simplifying the equation: v = 3

Therefore, the speed of the first cyclist is 3 meters per second.

Solving the equations

Let's solve the equations you provided:

1. X - 546 = 35 + 64

To solve this equation, we need to isolate the variable 'X' on one side of the equation. We can do this by performing the same operation on both sides of the equation. In this case, we'll add 546 to both sides:

X - 546 + 546 = 35 + 64 + 546

Simplifying the equation: X = 645

Therefore, the solution to the equation X - 546 = 35 + 64 is X = 645.

2. X : 6 = 720 : 2

To solve this equation, we need to isolate the variable 'X' on one side of the equation. We can do this by performing the same operation on both sides of the equation. In this case, we'll multiply both sides by 6:

(X : 6) × 6 = (720 : 2) × 6

Simplifying the equation: X = 2160

Therefore, the solution to the equation X : 6 = 720 : 2 is X = 2160.
