1 / 6 + 7 / 12 * (3 / 4-1 / 6)

=1/6+7/12*3/4-7/12*1/6
=1/6*(1-7/12)+7/16
=1/6*5/12+7/16
=5/72+7/16
=10/144+63/144
=73/144

Party A, Party B, Party C and Party D donated money to the Sichuan disaster area. Party A's donation is one-third of the total donation of the other three people, Party B's donation is one-fifth of the total donation of the other three people, and Party C's donation is one sixth of the total donation of the other three people?

A accounts for 1 / 3 of the total number (1 + 1 / 3) = 1 / 4
Party B accounts for 1 / 5 of the total number (1 + 1 / 5) = 1 / 6
C accounts for 1 / 6 (1 + 1 / 6) = 1 / 7 of the total
1-1 / 4-1 / 6-1 / 7 = 37 / 84
Total: 148 △ 37 / 84 = 336 yuan
A: 336 × 1 / 4 = 84 yuan

What's the difference between demand and demand? (Western Economics)
Sometimes, there is an option to increase demand. There is also an increase in demand. Is there any difference between the two?

The change of demand refers to the change caused by factors other than the price of the commodity, such as consumption habits, wage change, etc., which is shown as the parallel movement of the demand curve on the graph; the change of demand refers to the change caused by the change of the price of the commodity, which is shown as the relationship between different points on a demand curve

If the complex Z satisfies | z-3i | = 1, find the maximum of | Z + 2 |______ ．

|The point corresponding to the complex Z of z-3i | = 1 is a circle with C (0,3) as the center and 1 as the radius, | Z + 2 | denotes the distance between the point corresponding to the complex Z and a (- 2,0), ∫ AC | = 4 + 9 = 13, and the maximum value of | Z + 2 | is 1 + 13

What are the differences between axioms, theorems, lemmas, assertions and other mathematical attributes
For example, what's the difference between these attributives in mathematics? I hope it's clear and easy to understand

Axioms: propositions and principles that are true after long-term repeated human practice and do not need to be proved by other judgments. Theorems: propositions or formulas that can be used as principles or laws through theoretical proof. The difference between theorems and axioms is that axioms are "born" to exist

Please write an English composition with my favorite sport. About 100 words

MY FAVORITE SPORT
My favorite sport is swimming.
There are three reasons why I like the sport best.
First, it is good for keeping fit. It benefits the heart, the lungs and the limbs. Thanks to the sport, I lost my weight and I am graceful in form.
Second, it is easy to find a place to swim. In the country, I can swim in lakes and rivers. In the city, there are many swimming pools spotted among the residential areas.
Third, it can be done in any weather. It is very cool swimming in hot summer. In cold weather, swimming is especially refreshing.
Swimming is a very popular sport. I hope you can enjoy it too

In △ ABC, ab = AC, BC = 10cm. If the perimeter of the triangle is less than 44cm, the value range of AB is obtained

5＜AB＜17

How to find the greatest common factor in fifth grade mathematics
The greatest common factor of 10 and 21

10＝2×5
21＝3×7
So the greatest common factor of 10 and 21 is 1

The area ratio of two similar triangles is 16:9, and the difference of their perimeter is 4cm. Find the perimeter of the larger triangle

The square of the ratio of the circumference of similar triangles is equal to the ratio of their areas
Therefore, the ratio of perimeter is 4:3
Let each copy be K, then
4k-3k=4
k=4
So, 4K = 4 * 4 = 16
That is, the perimeter of the larger triangle is 16cm
