Volume of cylinder:
=area large×height
= 3.14×11×11×15
=5699.1
Hopes help!
The equation would be 28-2.50x since it's 2.50 per ride, you would be able to ride 11 rides total
We have been given that length of PQ and QR is 25 cm and 8 cm respectively.
We can find possible side length of PR in order to form a triangle using triangle inequality theorem.
Triangle inequality theorem states that the sum of lengths of two sides of a triangle must be greater than length of third side of triangle.
The length of PR should be either less than sum of PQ and QR or greater than difference of PQ and QR.
Let us find the other possible length of PR.
Therefore, the length of PR should be either less than 33 or greater than 17 so that PQ, QR and PR can form a triangle.
Answer:
(a)
Given expression: 49% of 162
we can write 49% as
then;
Therefore, the estimate of the given expression is, 79.38.
(b)
Using mental math to calculate 49% of 162.
Mental math is used as a way to calculate an estimate quickly.
We can write 49% = 50% -1%
(50%-1%) of 162 = 50% of 162 -1% of 162
so,
50% of 162 =
and
1% of 162 =
Now, subtract these we get;
81 - 1.62 = 79.38
Therefore, by using mental math 49% of 162 is, 79.38
The equation used to solve the problem would be 12.99 - 2.10b = 21.39
