Answer:

So starting with:

1000 ft / 5 min

we need to convert minutes into seconds, then divide the above value into it to get knots (follow the labels so they cancel out)

1000 ft / 5 min (1/60 min/sec) (1 kt / 1.68780986 ft/sec)

1.974946 kt

Sum of all natural numbers from100to300 which are divisible by 4and 5 is

My name is Ann [436]

If $x$ is a number that is both divisible by 4 and 5, then

$\begin{cases}x\equiv0\pmod4\\x\equiv0\pmod5\end{cases}$

4 and 5 are coprime, so we can use the Chinese remainder theorem to solve this system and find that $x=20n$ is a solution to the system, where $n$ is any integer. Simply put, any multiple of 20 fits the bill.

Now, there are 11 numbers between 100 and 300 that are divisible by 20 (100, 120, 140, and so on). We have $20n=100$ when $n=5$ , so the sum we want to compute is

$\displaystyle\sum_{n=5}^{15}20n=\boxed{2200}$

Let's solve!

Step-by-step explanation:

2x + 6x - 9 = 0

\____/

8x - 9 = 0

+ 9 + 9

8x = 9

8 8

x = 9/8 --or-- $1\frac{1}{8}$

x = 1.125

17.5% as a fraction in simplest form?

Vsevolod [243]

$17.5\%$ is the same thing as $0.175$ . We can rewrite this as $\frac{175}{1000}$ . Or course this is not simplified, so we can simplify to get $\boxed{\frac{7}{40}}$ .
