The line of symmetry can never be symmetrical. If you put a vertical line through the middle the sides aren't equal. Same for horizontal and diagonal.
Answer:
61
Step-by-step explanation:
Since we now that avalanches occur at 245 mph and that is 4 times as fast as a skier. So we can divide 245/4 = 61.25 ≈61
Hope This Helps!
If it does pls mark me brainliest. (Your question made me rank up)
Find coterminal angles Ac to a given angle A.
What are coterminal angles?
If you graph angles x = 30o and y = - 330o in standard position, these angles will have the same terminal side. See figure below.
<span><span><span> </span> </span> </span>
Coterminal angles Ac to angle A may be obtained by adding or subtracting k*360 degrees or k* (2 Pi). Hence
Ac = A + k*360o if A is given in degrees.
or
Ac = A + k*(2 PI) if A is given in radians.
where k is any negative or positive integer.
Example 1: Find a positive and a negative coterminal angles to angle A = -200<span>o</span>
Answer:
[-2.5, -2]
[-2, -1.5]
[1.5 , 2)
[2, 2.5)
Step-by-step explanation: please give this brainliest answer I just took the test it’s correct
1) When you're finding ratios, the best thing to do is to add the parts together to find what one part is.
2+4= 6. Then divide this by the total- 18/6=3.
Therefore, the ratio of red to brown chairs is 2*3:4*3
Therefore, the amount of red chairs is 12.
2) The best thing to do i to find out how long it takes him to read one book them multiply this by 15.
To do this, simply divide the amount of time by the amount of books that he has read.
30/10= 3
Therefore, Rock can read a book in three minutes. As he is reading 15, you multiply these together.
3*15= 45
Therefore, it will take Rock 45 minutes to read 15 books.
3) The best thing to do is to find out what one pastry costs, and you can do this by dividing the cost by the amount of pastries.
160/8= 20.
Therefore, one pastry costs $20.
As you want to find the cost of 16 pastries, you simply times these together.
20*16= 320
Therefore, 16 pastries cost $320.
Hope this helps :)
