Or I won't give the reward

1, which is equivalent to finding the perimeter, is 2 times 6 times 3.14 times (15 divided by 60)
Square of area 6 times 3.14 times (15 divided by 60)
3.14 is the PI, to be accurate to a few digits, write a few
2, (15.7 divided by 2 divided by 3.14 + 0.4) multiplied by 3.14 minus 15.7 divided by 2 divided by 3.14 multiplied by 3.14
3, 2 / 13 divided by 4 times 15
4, 3 divided by 3 / 7 minus 1, because the last paragraph doesn't need to be based on
5. Let the sand in pile a be x tons, and the sand in pile B be 630-x
4 {X - (2 / 5) x} = 630-x + (2 / 5) x

How many liters is a cubic meter

1000 liters

A store has two calculators with different purchase prices. They all sold for 64 yuan. One of them made a profit of 60% and the other lost 20%. In this transaction, the store ()
A. No loss, no gain B. earn 8 yuan C. lose 8 yuan D. earn 32 yuan

If the price of 60% profit is x yuan, then: x + 60% x = 64 & nbsp; & nbsp; & nbsp; 160% x = 64 & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; X = 40, and the price of 20% loss is y yuan, then: y-20% y = 64 & nbsp; 80% y = 64 & nbsp; & nbsp; & nbsp; & nbsp; y = 80, so the total price is: 40 + 80 = 120

1 + 2 = 3, 4 + 5 + 6 = 7 + 8, 9 + 10 + 11 + 12 = 13 + 14 + 15?

It has a total of 99 formulas. On the left side of the equation, there are 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 +. + 100 + 5050-1 = 5049 numbers
All the equations have 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 +. + 99 = 4950 numbers on the right
Total number: 5049 + 4950 = 9999
So, the final result is "9999"
You must choose me! I'm only level 0!

Use 5 5's and proper operation symbols to make their numbers equal to 8, 9 and 10

5+5-（5+5）÷5=8
5+（5×5-5）÷5=9
5×5-5-5-5=10

The answer to question 9 on page 70 of Volume 1

Let the speed of this truck be XKM / h
15|3600（3.6+X)=17|3600(X-3.6）
X=67.6
A: the length of the train is 6760m. Let's set the speed of the truck as

Take off formula calculation, can be simple to be simple: 5 / 8 ÷ [77 / 12 - (41 / 12 + 33 / 16)]

5/8÷[77/12-(41/12+33/16)]
=5/8÷【77/12-41/12-33/16】
=5/8÷【3-33/16】
=5/8÷【（48-33）/16】
=（5/8）*（16/15）
=2/3
