Let's see -
3,839 would be rounded UP to 4,000, since the 3 tells the 8,
"Hey, can I borrow a cup of sugar?" And the 8 says,
"Of course!"
Notice the 3 says "A cup of sugar", which is ONE.
If you add ONE to three, it makes 4. Then the rest of the numbers turn into zeros.
OR, you could go about it with a helpful rhyme:
5 or more, raise the score!
4 or less, let it rest!
This just shows you that if the number is bigger, round UP.
If the number is smaller than 4, round DOWN or keep it the same.
In this case, 8 is larger than 3, so we would round up to 4,000.
Answer:
Check below
Step-by-step explanation:
1) Check the rectangle below with a line k, the axis of rotation in the center of the figure.
2) Since it has a perimeter of 32 units and it is to be rotated about the line, the solid to be created it is a cylinder. As you can see below.
3) Let's calculate its radius, based on the information given, i.e. the perimeter:
Since the line of rotation is the center, and the radius is half the line segment of the basis, then the radius is 5.
Answer:
6.79 is the tip
the total 52.07
Step-by-step explanation:
45.28 +( 15%= 6.79)
45.28 + 6.79 = 52.07
Answer and Step-by-step explanation:
The sides we have are 7, , and .
The square root of 80 is less than 9 but greater than 8 (because is 64, is 81, and 80 is in between those two values), and the square root of 31 is definitely less than the square root of 80.
So, is the longest side.
1) The square of is:
2) The sum of the squares of the two shorter sides is:
3) Since the square of the longest side is equal to the sum of the squares of the two shorter sides, by the Pythagorean Theorem, the triangle is a right triangles.
Hope this helps!
I think is A. 1/20 the answer I think
