You're answer is correct. If you round up and estimate to the whole number it would be 9 yards. If you add the total it would 10 yards. You have at least 6 yards so a & b would be out. Then 3/4 three times would be greater then 1/2. So c would be out as well.
Consider first two digits and then the next two digits.If there are three digits in the given number then first consider the first digit and then the take two digits together
6 | 4489 | 6x
36
12x | 889 |
Now the number 889 has 9 in units place so take a share number which has 9 at the end (ex.3*3=9 and 7*7=49)
So put 7 in the place of x and multiply the x value with 12x(that is 127) u will get the remainder as 0
Therefore the square root of 4489 is 6x*6x i.e. 67*67=4489
Answer: The required volume is 390 mm³.
Step-by-step explanation: Given that the stack on the left is made up of 15 pennies, and the stack on the right is also made up of 15 pennies. The volume of the stack of pennies on the left is 390 mm³.
we are to find the volume of the stack of pennies on the right in cubic millimeters.
The number of pennies on the left and right are same, equal to 15.
Also, the volume of the stack of pennies on the left is 390 mm³.
Since the number of pennies on the right and left are equal, so the volume of the stack on the right and left are also equal.
Therefore, the volume of the stack of pennies on the right is 390 mm³.
Thus, the required volume is 390 mm³.
Answer:
Step-by-step explanation:
You don't need the Law of Cosines, the Law of sines if what you need. You can't use the Law of Cosines because in order to find side a, you would need the length of side c and you don't have it. Using the Law of Sines is appropriate, knowing that angle B = 55:
and solving for a:
so
a = 143.0
The answer is 42m . have a good day!
