<>ah+ab=56

a（h+b）=56

Decompose the prime factor, 56 = 2x2x2x7

If a = 2, then h + b = 28, 28 can be decomposed into the sum of two exponents: 5 + 23, or 11 + 17.

Therefore, a = 2, b and h are equal to 5 and 23 respectively, or 11 and 17 respectively, all of which are met by random sails.

In this case, the volume width of the box is 2x5x23=230 or 2x11x17=374.

If a=7, then h+b=8, 8 can only be decomposed into the sum of two prime numbers 3+5, and the volume of this hailstorm cuboid = 7x3x5 = 105

1.The volume ratio of the cube is the cube of the edge-to-length ratio: 2 2 2:

3×3×3=8:272.If the number A is 20% more than the number B, then the number A is (1+20%) times the number of B, that is, the number of A:

B number = 1 + 20% = 120:100 = 6:5

3.Since the ratio of the length of the three sides is 3:4:5, the length of the three sides is 3a, 4a, and 5a respectively.

Then 3a+4a=

So a= , therefore, the two right-angled sides are meters and meters.

So the area of the triangle s=1 2 square meters).

4.Assuming that bag A of rice is originally x kg, then bag B of rice weighs (80-x) kg, then there is (x-5): [80-x)-7]=8 9(x-5) 9=[(80-x)-7] 8

x=37

The edge-to-length ratio is 2:3, and the volume ratio is 8:27; The number A is 20 more than the number B, and the ratio of the two numbers A and B is 6:

5；For a right-angled triangle, the ratio of the length of the three sides is 3:4:5, and the sum of the two right-angled sides is meters, so the two right-angled sides are meters and meters, and the area is naturally square meters.

The two bags of rice weigh a total of 80 kilograms, and if bag A pours out 5 kilograms and bag B pours out 7 kilograms, the mass of bag A is eight-ninths of that of bag B. Set the original x kg of rice in bag A to get x-5 = (80-x-7) (8/9). Get x=37

It runs 5 steps and the rabbit has to run 9 steps, but the rabbit moves fast, and the hound can run 3 steps when it takes 2 steps, I know.

The hound step is 9 5 steps of the rabbit, the same time The rabbit 3 steps, the hound distance is the rabbit's 18 5 v rabbit: v hunting = 5:6 Let the time be t

6-5) x t=10 to get t=10

10x6 = 60 meters.

A: Run 60 meters to catch up with the rabbit.

The correct answer is that the hound runs at least 60 meters to catch up. Solution: From "the hound runs 5 steps, the rabbit runs 9 steps", it can be seen that when the hound runs a meter per step, then the rabbit runs 5 9 meters per step.

From the time when the hound runs 2 steps, but the rabbit can run 3 steps, it can be seen that at the same time, the hound can run 2a meters, and the rabbit can run 5 9a * 3 5 3a meters. Thus, it can be seen that the speed ratio of the hound to the rabbit is 2a:5 3a 6:

5, that is to say, when the hound runs 60 meters, the rabbit runs 50 meters, and the original difference of 10 meters is just after the chase.

Multiply the outside of the brackets and reduce the score to get = 2002 out of 2001 + 2001 points 2002

Hello! Please type out the question! Thank you! Laugh at it!

What is the topic, I don't have a book in my hand.

A: I bought 3,500 yuan of treasury bills.

Interest = Principal Interest Rate Time.

Principal = Principal + Interest = Principal + Principal Interest Rate Time = Principal (1 + Interest Rate Time) Therefore, Principal = Principal and Interest (1 + Interest Rate Time), that is, Yuan).
