How many grams per square meter is 16 ounces,

How many grams per square meter is 16 ounces,

1 pound = 454 grams = 16 ounces
1 yard = 3 feet = 36 inches = 36 * 2.54 cm = 91.44 cm = 0.9144 M
PSI = 454 / 0.9144 ^ 2 = 543 g / m2
Ounces / square yard = 33.9 g / square meter
Lbs / m2 = 454 g / m2

If we know that the image of the first-order function y = am + B passes through (0,2) point, and the figure enclosed by it and the coordinate axis is an isosceles triangle, then the value of a is?

Y = ax + B, substituting the point (0,2), B = 2, y = ax + 2
1. If a is negative,
If the straight line is downward, then the intersection point with the X axis is (2,0), substituting y = ax + 2, we can get a = - 1
2. If a is positive,
If the straight line is climbing up, then the intersection point with the X axis is (- 2,0). Substituting y = ax + 2, we can get a = 1

Judge (in a factory, the number of male workers is 60% of the number of female workers, then the number of male workers accounts for 37.5% of the total number of factory workers)

Yes

X / x ^ 2-25-5 / x ^ 2 + 10x + 25 2-x / X-1 divided by (x + 1-3 / x-1) known 1 / X-1 / y = 5, find the value of 2x + 4xy-2y / x-3xy-y

The first question is not clear
Second question:
1/x-1/y=5
We can deduce that Y-X / xy = 5, that is, X-Y = - 5xy
(2x + 4xy-2y) / (x-3xy-y) can be reduced to
[2(x-y)+4xy]/(x-y-3xy)
Take the above equation into account
（-10xy+4xy)/(-5xy-3xy)
That is - 6xy / - 8xy
Reduced to 3 / 4

5、 There are 52 students in class 2 who have reached the standard of physical education in the last semester, of which 28 are boys. How many of them are boys and girls?

A: the number of boys reaching the standard is 712, and the number of girls reaching the standard is 512

When x2 + 2Y2 = 1, find the maximum value of 2x + 3y2

When x2 + 2Y2 = 1, y2 = 1 − X22 ≥ 0, and 2x + 3y2 = 2x-3 − 3x22 = 32 (x + 23) 2-136, so when x = - 23, the minimum value of 2x + 3y2 is - 136, and when x = 1, the maximum value of 2x + 3y2 is 2

The number of three classes in Grade 6 of a school is between 100 and 150. In the school sports meeting, class 6 (1) accounts for 1 / 6 of the whole grade, class 2 accounts for 1 / 8, and class 3 accounts for 1 / 9. How many people are there in Grade 6
Why multiply by two? 72 × 2 = 144 (people)
Why multiply by two?

If class 6 (1) accounts for 1 / 6 of the whole grade, class 2 accounts for 1 / 8 and class 3 accounts for 1 / 9, the number of students in the whole grade is a multiple of 6, 8 and 9
Because the least common digits of 6, 8 and 9 are 72
150÷72=2…… six
So 72 × 2 = 144
