Electronic flea game board the electronic flea game board is △ ABC, ab = AC = BC = 6 The electronic flea game board is △ ABC, ab = AC = BC = 6, if the electronic flea starts at point P0 on the side of BC, bp0 = 2, the first step flea jumps to point p1 on the side of AC, and CP1 = CP0; the second step flea jumps from point P1 to point P2 on the side of AB, and ap2 = AP1; the third step flea jumps from point P2 to point P3 on the side of BC, and BP3 = bp2 If the flea picks down according to the above regulations, the n-th point is PN, then the distance between P2009 and p2010 is___ .

Electronic flea game board the electronic flea game board is △ ABC, ab = AC = BC = 6 The electronic flea game board is △ ABC, ab = AC = BC = 6, if the electronic flea starts at point P0 on the side of BC, bp0 = 2, the first step flea jumps to point p1 on the side of AC, and CP1 = CP0; the second step flea jumps from point P1 to point P2 on the side of AB, and ap2 = AP1; the third step flea jumps from point P2 to point P3 on the side of BC, and BP3 = bp2 If the flea picks down according to the above regulations, the n-th point is PN, then the distance between P2009 and p2010 is___ .

If we calculate slowly, we can see that. P0 is coincident with p6. So we can judge that every six are a cycle. Because p2010 and P2009 jump 2010 and 2009 times respectively. Through calculation, we can get that p2010 and P2009 coincide with P0 and P5 respectively, so we connect P5 and P0 according to similar data, we can get that

An electronic flea starts from the origin of the number axis. It moves one unit to the left for the first time, two units to the right for the second time, three units to the left for the third time, and four units to the right for the fourth time. By 2007, where is the flea? If the flea starts from - 8, where is it after 2008?

The first question is - 1004. I assume starting from 0. Because the first jump left - 1 right is 1, so (2007 + 1) / 2 = 1004 = 1004, because the number of bits is singular, it is negative
2 the same as above. It should be 1004-8 = 996

If & nbsp; & nbsp; - a | M-3 | B & nbsp; and 1 / 3 AB ^ | 4N | are of the same kind, and m and N are negative reciprocal, find the value of M

|m-3|=1
1=|4n|
mn=1
From the above three equations, it is concluded that
m=4,n=1/4

Ask a math problem. A clothing store will increase the price of a certain clothing by 35%
A clothing store will increase the purchase price of certain clothing by 35%, and then make an advertisement of "10% discount" and send out 50 yuan taxi fare. As a result, each clothing still makes a profit of 208 yuan. How much is the purchase price of each clothing?
I've been thinking about it for a long time
But. It seems that. 285 / 0.215

1200
Formula: 1.35 * x * 0.9-50 = x + 208
X is the purchase price

The owner of a clothing store sold two suits with different prices for a yuan, one of which made a profit of 60% and the other lost 20%
(1) In this business, did the owner of the clothing store make a profit or lose?
(2) How much did you earn or lose (expressed in an algebraic expression with a)?
Big brothers and big sisters

Let the purchase price of one piece be x and the other be y
First: (A-X) / x = 60%
(a-X)/X=0.6
a-X=0.6X
a=x+0.6X=1.6X
x=a/1.6=5a/8
Another: (Y-A) / y = 20% = 0.2
y-a=0.2y
y-0.2y=a
0.8y=a
y=a/0.8=5a/4
The total price of two pieces is: x + y = 5A / 8 + 5A / 4
X+Y= （5a +10a)/8=15a/8
Total selling price total purchase price = 2A - (x + y) = 2A - 15A / 8 = A / 8
The minus value is a positive number, so I earned, earned a / 8

The price of a commodity is reduced by 1 / 5 for the first time and 1 / 5 for the second time. The current price is ()
Please list the formula

16／25

After a 5% reduction, the price of a product is 80 yuan. How much is the original price of the product

80 divided by 1 minus 1 in 5 = 100

The cost of a commodity is 80 yuan per piece. If it is sold at the original price, 100 pieces can be sold every day, and the profit of each piece is 15% of the cost. Later, it is sold at 90% of the original price, and the daily sales volume is increased to 1.5 times of the original. Then, compared with the money earned every day later, what you earn more is ()
A. The original B. later C. as much as D. can not be compared

The original price: 80 × (1 + 15) = 96 (yuan); the original profit: 80 × 15 × 100 = 1600 (yuan); the current price: 96 × 90% = 86.4 (yuan); the current profit: 100 × 1.5 × (86.4-80), = 150 × 6.4, = 960 (yuan); 1600 ＞ 960, a: I used to make more money every day

When a commodity is sold at the original price, the profit is 13% of the cost. Later, it is sold at a 10% discount, and the daily sales volume is doubled. After the discount, the daily total profit of this commodity is increased compared with that before the discount______ %．

Suppose the cost is 1 and the original sales volume is a, then the original selling price is 1 + 13 = 43, the price after 10% discount is 43 × 90% = 1.2, the profit after discount is 1.2-1 = 0.2, the sum of the original profits is 13a, the profit after doubling the sales volume is 0.2 × 2A = 0.4A, the more percentage is: (0.4a-13a) △ 13a, = (25-13
