Answer:
11
Step-by-step explanation:
dude just use a calculator lol
The area wiped by the viper blade is approximately 486.7 square inches.
The area wiped by the wiper blade (
), in square inches, is equal to the area of the circular section described below:
(1)
Where:
- Angle, in sexagesimal degrees.
- Inner radius, in inches.
- Outer radius, in inches.
If we know that
,
and
, then the area wiped by the wiper blade is:
![A = \frac{130\pi}{360} \cdot [(25\,in)^{2}-(14\,in)^{2}]](https://tex.z-dn.net/?f=A%20%3D%20%5Cfrac%7B130%5Cpi%7D%7B360%7D%20%5Ccdot%20%5B%2825%5C%2Cin%29%5E%7B2%7D-%2814%5C%2Cin%29%5E%7B2%7D%5D)

The area wiped by the viper blade is approximately 486.7 square inches.

The relationship between fractions and decimals is that with a fraction you are dividing whereas a decimal is treated like a number.
i.e. 1/4=0.25
Think of decimals as 100 being the whole or 1 so split 100 into 4 and you get 25 or 0.25
This involves a bit of logic in thinking about what LCM actually means.
LCM is the least common multiple. A
common multiple is a multiple shared by two or more numbers. And by
multiple, we mean some number multiplied by successive integers; this set contains multiples of 5 {5, 10, 15, 20, 25...}. You can see that the least (or lowest) common multiple is the lowest multiple shared by two numbers. Like for 6 and 9, you have {6, 12,
18, 24...} and {9,
18...}, so LCM(6,9) = 18.
Now, if an LCM must be shared by both numbers, and to get a multiple of the largest number, you have to multiply by an integer greater than or equal to 1, then the LCM of two numbers can never be less than the larger of the twi numbers. Generally, if x and y are positive real numbers, and x is greater than y,
