Turn the clock from 3 o'clock in a counter clockwise direction for 174 hours, then in a clockwise direction for 116 hours, and then in a counter clockwise direction for 125 hours, and then Turn it clockwise for 164 hours. What time does the clock last fall

Set the counter clockwise direction to a negative number
Rotation time = - 174 + 116-125 = - 183 hours
183=12*15+3
12 hours for a circle, so, the final equivalent of three hours after the dial
So, at 12 o'clock

Is the rotation direction of typhoon the same as that of hurricane? Please explain

A typhoon is a violent storm that occurs in the tropical oceans of the Northwest Pacific and the South China Sea. You must have seen eddies in rivers from time to time. In fact, a typhoon is an air vortex that rotates rapidly around its center in the atmosphere and moves forward at the same time. It rotates counterclockwise in the northern hemisphere, It rotates clockwise in the southern hemisphere. In meteorology, the vortices in the atmosphere are called cyclones. Because typhoon, the vortices in the atmosphere, are produced in the tropical ocean, they are called tropical cyclones. Typhoon is a violent storm that occurs in the tropical ocean of the Northwest Pacific and the South China Sea. You must have seen vortices appear in rivers from time to time, A typhoon is an air vortex that rotates rapidly around its center in the atmosphere and moves forward at the same time. It rotates anticlockwise in the northern hemisphere and clockwise in the southern hemisphere. In meteorology, the vortex in the atmosphere is called a cyclone. Because the vortex in the atmosphere is generated on the tropical ocean, it is called a tropical cyclone, It's a violent storm in the tropical ocean of the Northwest Pacific and the South China Sea. You must have seen eddies appear in rivers from time to time. In fact, a typhoon is an air vortex rapidly rotating around its center in the atmosphere and moving forward at the same time. It rotates counterclockwise in the Northern Hemisphere, It rotates clockwise in the southern hemisphere. In meteorology, the vortices in the atmosphere are called cyclones.

It rotates counterclockwise in the northern hemisphere and clockwise in the southern hemisphere. In meteorology, the vortex in the atmosphere is called a cyclone because it is produced in the tropical ocean, So it's called a tropical cyclone. How do hurricanes form? Typhoons and hurricanes belong to tropical cyclones in the northern hemisphere, just because they are produced in different sea areas and are called different names by people in different countries. In the northern hemisphere, cyclones generated on the ocean surface from the east of the international date line to the Greenwich meridian are called hurricanes, In general, tropical cyclones in the Atlantic Ocean are called hurricanes, Tropical cyclones in the Pacific Ocean are called typhoons. Three conditions are needed for the formation of a hurricane: warm waters; humid atmosphere; wind on the ocean surface can turn the air into an inward rotating flow. In most storm structures, the air will become warmer and higher, and finally flow to the outside atmosphere, In the eye of a hurricane, the sky is relatively calm. The most severe weather phenomenon occurs in the atmosphere near the eye of a hurricane, which is called the eye wall. In the upper layer of the eye wall, most of the air flows out, which intensifies the upward movement of the atmosphere

Is the direction of typhoon activity in the northern hemisphere clockwise or counterclockwise? In the southern hemisphere? In the equator?

Due to the geostrophic bias force, that is, Coriolis force, typhoons in the northern hemisphere rotate counterclockwise, while typhoons in the southern hemisphere rotate clockwise. There is no typhoon at the equator, because typhoons cannot form near the equator

Hurricane in the northern hemisphere is counter clockwise rotation, in the southern hemisphere is clockwise because of what? That in the equator is to which direction?
Why can't there be a hurricane at the equator?

The so-called hurricane is a typhoon (called typhoon in the Pacific Ocean, hurricane in the Indian Ocean and Atlantic Ocean). It is a low-pressure tropical and subtropical large-scale cyclone system. Due to the earth's rotation, the earth will produce an geostrophic deflection force, which makes the objects on the earth (except the equator) deflect along the latitude line

If the area ratio of two similar triangles is a, the perimeter ratio is B, and a + B = 6, what is B / a equal to

1/2

If the perimeter ratio of two similar triangles is 23 and their area difference is 25, then the area of the larger triangle is 25
I want steps and ideas, not guesswork

25*3=50

If the perimeter ratio of two similar triangles is 23 and the area difference between them is 25, then the area of the larger triangle is? Faster, for a reason

If the ratio of perimeter is 2:3, the ratio of area is 4:9. If the larger triangle area is 9K, the smaller triangle area is 4K,
Because their area difference is 25, so 9k-4k = 25
That is, 5K = 25, k = 5. So 9K = 45

The area ratio of two similar triangles is 16:9, and the difference of their perimeter is 4cm

The area ratio is 16:9, so the side ratio of two triangles = height ratio = perimeter ratio = 4:3
Let the perimeter of the larger triangle be y and the perimeter of the smaller triangle be X
y-x=4
y:x=4:3
Results y = 16, x = 12

If the area ratio of two similar triangles is 1:2, what is their perimeter ratio?
…

1 ：√2

If the area ratio of two similar triangles is the square of K and the perimeter ratio (1-k), then K=____

The area ratio of similar triangles is the square of similar ratio, and the title gives the square of K
The perimeter ratio of similar triangles is equal to that of similar triangles, and the topic gives the perimeter ratio (1-k)
Obviously, the area ratio of a triangle is the square of its perimeter
Square of k = (1-k)
k*2=k*2-2k+1
2k=1
k=1/2
