It is Pets Week at school.
Millie brought a poetry book about animals to school
and here are her favourite poems.
My Dog My dog is the cleverest animal of all.
He doesn't just chase and catch a ball.
With eyes open wide,He hunts when I hide.
He does wonderful tricks.Builds me camps out of sticks.
He'd never bark or bite.
And he doesn't like to fight.
My dog is my very best friend.
And I'll look after him until the end.

The area of a classroom is 64.08 square meters, with a side length of 0.6 decimeters of square tiles, how many tiles do you need?

0.6 decimeter = 0.06 meter
64.08÷（0.06×0.06）
=64.08÷0.0036
=17800 yuan
A: we need 17800 of these tiles

Cut a piece of square paper with an area of 50 square centimeters into four identical isosceles triangle pieces, and then put them together into a rectangle, the length of which is () cm
A. 5cm B. 8cm C. 10cm D. 12.5cm

Cut the square into four identical isosceles right triangle pieces, as shown in the following figure: the area of each small triangle is: 50 △ 4 = 12.5 (square centimeter); then the product of the two waists of the small triangle is: 12.5 × 2 = 25 (square centimeter); 5 × 5 = 25, so the waist length of each small triangle is 5 cm; these four

Sine theorem and cosine theorem
In the triangle ABC, B = 10, a + C = 2B, C = 2A, find a and C

From the sine theorem, a / Sina = C / sinc, and because C = 2A
Substituting a sin C = a sin 2A = 2 a sin a cos a = C sin a
That is, cosa = C / 2A
Cosa = (b ^ 2 + C ^ 2-A ^ 2) / 2BC = (100 + C ^ 2-A ^ 2) / 20c
(10-A) C ^ 2-100a + A ^ 3 = 0
A + C = 20, C = 20-a
∴(10-a)（20-a)^2-100a+a^3=0
Finishing a ^ 2-18a + 80 = 0
The solution is a = 8, a = 10
Because B = 10 and a + C = 2B
When a = 10, C = 10, then ABC is an equilateral triangle, which does not conform to C = 2A;
So, a = 8, C = 12

If the solution set of inequality a (2x-1) > 3B (x-1) about X is the solution set of x2a-b

a(2x-1)>3b(x-1)
(3b-2a)x

Draw the largest semicircle in a rectangle 10 cm long and 8 cm wide. Its circumference is Cm, the area is Square centimeter

3.14 × 10 ／ 2 + 10 = 15.7 + 10 = 25.7 (CM) 3.14 × (10 ／ 2) 2 ／ 2 = 3.14 × 25 ／ 2 = 39.25 (square cm); answer: the circumference of this semicircle is 25.7 cm and the area is 39.25 square cm. So the answer is: 25.7; 39.25
