One hundred small squares with a side length of one centimeter are used to make a large square, and the area of the large square is one

One hundred small squares with a side length of one centimeter are used to make a large square, and the area of the large square is one

The side length of a large square is 10 cm
So the area of the large square is s = 10 × 10 = 100cm;

Given a = 0.00... 012 99 zeros, B = 0.0... 025 100 zeros, C = 0.0... 08 100 zeros, find a / (b * c)

According to your description:
a=12/10^101
b=25/10^102
c=8/10^101
A simple algorithm
Divide the formula into two parts
a×1
- -
c b
So a / C is 12 / 8 = 1.5
The formula becomes
1.5/b
=1.5×10^102/25
=0.06×10^102
=6000... 0 (100 zeros)
=6×10^100
I hope the answer will help you

DX / dt = 6T + 2, dy / dt = (3T + 1) sin (T ^ 2), find d ^ 2Y / DX ^ 2
Isn't d ^ 2Y / DX ^ 2 directly derived from dy / DX

dy/dx＝（3t+1）sin（t²）/(6t+2)=1/2sin（t²）
dt²y/dx²
=d [1/2sin（t^2)]/dx
=t*cos(t²)*dt/dx
=t*cos(t²)/(6t+2)

Use two squares with a circumference of 8 cm to form a rectangle. The circumference of the rectangle is______ Cm

Side length of the square: 8 △ 4 = 2 (CM) perimeter of the rectangle: (2 × 2 + 2) × 2 = 6 × 2 = 12 (CM) answer: the perimeter of the rectangle is 12 cm

Find the surface area of a cylinder, the perimeter of the bottom is 50.24 cm, and the height is 8 cm

50.24*8=401.92 (cm^2)
Because r = 25.12/π
Substituting 2 π R ^ 2, we can get the area of two circles, and 401.92 is the surface area of the cylinder

What are the meanings of M +, M -, MRC, GT and Ce on the calculator? Thank you

When you input a certain number on the calculator, click m + or M - to save the number. You can input other numbers. When you need the front number, click MRC to adjust the front number. CE stands for clearing the number 0, GT is not commonly used, and it seems to clear the number 0

What is the differential of the reciprocal of the product of the third power of SiNx multiplied by the fifth power of cosx?

d{[(sinx)^3*(cosx)^5]^(-1/2)}
=(-1/2)[(sinx)^3*(cosx)^5]^(-3/2)*[3(sinx)^2*cosx*(cosx)^5-(sinx)^3*5(cosx)^4*sinx]dx
=(-1/2)[(sinx)^3*(cosx)^5]^(-3/2)*[3(sinx)^2*(cosx)^6-5(sinx)^4*(cosx)^4]dx
Because it's differential, we add DX after it

3.5 times of a number is more than 1.2 times of this number

Let this number be x.3.5x-1.2x = 46, & nbsp; & nbsp; & nbsp; & nbsp; 2.3x = 46, 2.3x △ 2.3 = 46 △ 2.3, & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; X = 20; a: this number is 20

Comparison sign: division sign △ equal sign = unknown x, multiplication sign ×
1. Hongguang primary school bought a 135m long plastic rope. If you can make five skipping ropes with 9m, how many skipping ropes can you make with the 135m long plastic rope
2. Think about it: can you use the four numbers 2.8, 0.2, 7, 0.5 to form different ratios? Write at least four groups of ratios

Question 1: suppose you can do X skipping ropes,
9:5=135:x
9x=675
x=75
Question 2: 1, 2.8:7 = 0.2:0.5
2、7:2.8=0.5:0.2
3、0.2:0.5=2.8:0.7
4、0.5:0.2=0.7:2.8

Given the linear function Y1 = 3x + 3, y2 = - 2x + 8, then when Y1 > Y2, the value range of X is obtained

X﹥1
Y 1 > y 2
∴3x+3＞-2x+8
∴ 5x＞5
X > 1
