How many milliliters is a liter of water? I read on the Internet and said: the normal amount of drinking water a day is best 1.5 liters, then I would like to ask: how many ml is a liter? How many jin is a liter? Is a liter = 2 liters?

One liter is one liter, which is 1000 milliliters
It's 1000 grams, that's 2 jin

Solving equation (16 + x) / (80 + x) = 50%

Hello
（16+x）/（80+x）=50％
16+x=50%(80+x)
16+x=40+0.5x
x-0.5x=40-16
0.5x=24
x=48

It is known that a is an n matrix, a ^ 2 = a, and rank (a) = R. it is proved that a can be similar diagonalized, and the similar diagonal form of a and the value of determinant | a + e | are obtained

Because a ^ 2 = a
So the eigenvalues of a can only be 0 and 1
And R (a) + R (e-A) is obtained from a (e-A) = 0

When the outdoor wet bulb temperature is 0 and the dry bulb temperature is 3.5, what is the outdoor relative humidity? When the outdoor temperature is 0, how to calculate the relative humidity?

Finding the limit of (1-cos2x) / X * SiNx when x → 0

cos2x=1-2sin²x
So 1-cos2x = 2Sin & sup2; X
So the original formula = 2sinx / X
The limit of SiNx / X is 1
So the limit of the original formula is 2

Simple calculation: 5 / 8 * 3 / 7 * 4 / 5

5/8*3/7*4/5
=（5/8*4/5）*3/7
=1/2*3/7
=3/14

Factorization of (2x + 3y-3) (2x + 3Y + 7) - 11

Let a = 2x + 3Y
Original formula = (A-3) (a + 7) - 11
=a²+4a-21-11
=a²+4a-32
=(a+8)(a-4)
=(2x+3y+8)(2x+3y-4)

What's the difference between the product of 2 / 15 and 3 minus the quotient of 2 / 15 divided by 3?

2/15×3-2/15÷3
=2/5-2/45
=16/45

Write out the parameter equation of the straight line with inclination angle of 3 π / 4 passing through point a (- 1,2), and find the intersection point of the straight line and circle x2 + y2 = 8

The slope of a straight line is tan3 π / 4 = - 1. Let the equation be: y = - x B, bring the coordinate of point a into the equation to get b = 1. So the equation is y = - x 1, and then combine y = - x 1 with X & # 178; Y & # 178; = 8 to get x = √ 30 / 2, y = (1 - √ 30) / 2. The result is not known, but the idea must be right!
