There are 270 triangles, squares and circles, arranged by 2 triangles, 3 squares and 4 circles. How many circles are there?


270/(2+3+4)=30
30*4=120



How many boxes, how many circles and how many triangles are there
How many circles are there, how many grey circles are there, and how many black circles are there
How many circles are there


Question 1: period is three figures, each period has one square, circle and triangle. Then 99 is 33 periods, there are 33 squares, 33 circles and 33 triangles, plus the square of the 100th. So it is 34 squares, 33 circles and 33 triangles
The second question: the cycle is 6 figures, each cycle has 3 circles, 2 gray and 1 black. Then there are just 15 cycles by 90. There are 45 circles, 30 gray and 15 black



Triangle + triangle + triangle square = 12 squares + square + square triangle triangle = 2 how many triangles and squares?


Let triangle = a, square = B, the equations are as follows
(1)3a-2b=12
(2)3b-2a=2
(1)x2=6a-4b=24
(2)x3=9b-6a=6
Add to get 5B = 30, get b = 6,
Substituting a = 8 in (1)
So triangle = 8, square = 6



Triangle + triangle + triangle - Square - square = 12 square + square + square - Triangle - Triangle = 2 how many are triangle and square?


4 triangle-2 square = 12 ------ (1)
3 squares-2 triangles = 2
6 squares-4 triangles = 4 ------ (2)
(1) (2) add left and right separately
4 squares = 16 squares = 4
Bring in (1)
Triangle = 5



Triangle equals five stars, triangle x equals twenty, triangle equals several, star equals several


Triangle = 10;
Star = 2;
Let the triangle be x and the star be y,
Triangle equals five stars → x = 5Y;
Triangle * star equals 20 → x * y = 20;
5y²=20;
y²=4;
y=2;
x=5y=10.



Triangle Pentagram + Pentagram = Pentagram triangle star Pentagram =? Triangle =?


Is that it
89+9=98
☆=9 △=8



★÷△ =25…… 8. How many are five pointed stars and triangle stars


Let △ be n (n is a positive integer)
Then ★ = 25N + 8
For example, if n = 1, then {= 33; if n = 2, then} = 58
(triangle star is any positive integer, Pentagram is 25 times of triangle star plus 8.)



Circle triangle = 0.5 Pentagram square = 0.1 square + circle = 1.2····


Is: circle = 0.8 triangle = 0.3 Pentagram = 0.5 square = 0.4



How much power do you usually start with star delta


Let's say that 18.5kw operating current is 36a, so the starting current of direct starting is 160A, which is five times of the starting current. A short time of 160A may cause serious consequences to the power grid, such as tripping, insufficient voltage, burning down the transformer, and the starting current will be much smaller if the power is smaller. According to common sense, 15kw or above should be the star triangle, Over 45KW, the star delta may not meet the requirements. If the starting current is too large, the motor will be damaged. If the coil is 3mm, can the starting bear 160A current? If the motor is above 18.5kw, the starting time is at least 3S, and the 3S time can not stand it
