An enterprise purchased fire insurance from an insurance company. The premium is 40000 yuan, and the insurance rate is 0.75%. During the insurance period, the enterprise unfortunately encountered a fire and lost 6.5 million yuan of goods. The insurance company paid 5 million yuan. How much is the actual loss of the enterprise? (the answer in the book is 1.8 million yuan, but there is no calculation process. How can I calculate it, I don't believe the answer
Actual loss (cost) = premium + part not paid by insurance company = (4000 * 0.75%) + (650-500)
4000×0.75%+650-500
=30+650-500
=1.8 million yuan

A story book has 120 pages. Xiao Ming read two fifths of the whole book on the first day and 25% the next day. How many pages are left
Please all the experts, please 6 years old winter vacation life, experts help me
The answer looks like page 42? I didn't know you guys were coming
Day 1: 120X2 / 5 = 48
Day 2: 120x25% = 30
Total: 48 + 30 = 78
Remaining: 120-78 = 42
120x (1-2 / 5-25%) = 120x7 / 20 = 42 (page)
2 * 35-120% (1 / 25)
There are 42 Pages left
As shown in the figure, cut the cylinder with a circumference of 18.84 cm and a height of 10 cm into several equal parts to form an approximate cuboid. What is the surface area and volume of the cuboid? Surface area: Volume:
(1) The bottom radius is 18.84 △ 3.14 △ 2 = 3 (CM); the bottom area is 3.14 × 32 = 28.26 (cm 2); the surface area is 18.84 × 10 + 3.14 × 32 × 2 + 10 × 3 × 2, = 188.4 + 56.52 + 60, = 304.92 (cm 2); (3) the volume is 3.14 × 32 × 10, = 3.14 × 90, =

Xiao Ming read a story book. He read 20 pages on the first day, 25 pages on the second day, and the remaining 40% of the book was not read. How many pages are there in this story book?
(20 + 25) / (1-40%) = 45 / 60% = 75 (pages) a: there are 75 pages in this story book
If a bamboo pole is less than 6 meters long, measure it from one end to 3 meters, mark a, and then measure it from the other end to 3 meters, mark B. at this time, the distance of AB is 20% of the total length. What is the total length of the bamboo pole?
Setting: the total length of the bamboo pole is x meters
Equation 3 + 3-x = 20% X
The solution is: 6 = 1.2x
X=5
A: the length of the bamboo pole is 5 meters
What's more, the word "Chu" is wrongly typed as "Wai". Do you know
The total length of bamboo pole is x M
3+3-20%x=x
X=5
The bamboo pole is 5 meters long
If one is three meters away, then this problem is wrong.
If you measure 3 meters from one end outwards and 3 meters from the other end inwards, it is equivalent to x + 3-3 = X. if there is no quantity, you can't solve it.
Setting: the total length of the bamboo pole is x meters
Equation 3 + 3-x = 20% X
The solution is: 6 = 1.2x
X=5
A: the length of the bamboo pole is 5 meters
What's more, the word "Chu" is wrongly typed as "Wai". Do you know
The length of the bamboo pole is 1 meter
The distance of AB is = 20% * x = (3 + 3) - X
The solution of the equation is x = 5
Equation, let the total length of bamboo pole be x meters; (6-x) = 20% * x, solution x = 5
Or 6 / 1.2 = 5 meters, because the overlapping part is 0.2, the total length is 6 meters, in fact, the two are the same
The total length of bamboo pole is X,
AB=20%x，
x=3+3-20%x，
The solution is x = 5m
AB is 20% of the total length
If AB is x, the total length is 5x
Subtract AB from the two sides respectively, and the rest is 80% (3-x) + (3-x) = 80% * 5x
X = 1, the total length is 5
Three meters away? I feel like I can't solve it
(3 + 3) / (1 + 20%) = the total length of 5 (m) is unit 1. We take the sum of the two measurements as the comparison quantity, because the distance of AB is the overlapping part, so the corresponding score is 1 + 20%
Let all be x, then 3 + 3-20% x = x (because AB is calculated twice in 3 + 3 and subtracted once to get the total length of bamboo pole)
X = 5 meters. That's the right result
The total length of the bamboo pole is set as X meters; (6-x) = 20% * x = 5
Or 6 / 1.2 = 5m, because the overlapping part is 0.2 and the total length is 6m,
The product of two digits multiplied by two digits can only be three or four digits______ (judge right or wrong)
10 × 10 = 100 (three digits); 99 × 99 = 9801 (four digits)
Xiao Ming read a story book. On the first day, he read 25% of the whole book. On the second day, he read 5 more pages than on the first day. There are 30 pages left. How many pages are there in this book
Set a total of X pages
0.25*x+0.25*x+5+30=x
X = 70
Ask some sixth grade math questions (hope to do it in the way of sixth grade, and write down the calculation process, thank you)
Tian Tian went to the supermarket to buy a doll and a pen. She misread the decimal point of the doll's price and paid the cashier 12.85 yuan in total. The cashier told her to pay 40.30 yuan. How much are the doll and the pen?
There are two two decimal places, and their difference is 56.88. If the decimal point of the lower decimal is moved one place to the right, it will be equal to the larger decimal?
1. 40.30-12.85 = 27.45 yuan, 27.45/9 * 10 = 30.5 yuan, 40.30-30.5 = 9.8 yuan
Answer: Doll 30.5 yuan, pen 9.8 yuan
2. If the smaller decimal point moves one place to the right, it means that the two numbers are 1:10
56.88/9=6.32,
6.32+56.88=63.20
A: the two numbers are 6.32 and 63.20 respectively
