How many unique ways are there to arrange the letters in a word OPAL.

jek_recluse [69]

Answer:

24.

Step-by-step explanation:

We can use the factorial function to find the number of unique arrangements in a word.

There are 4 unique characters in 'OPAL'. As such, 4! = 24.

In the case that there were repeating characters, such as 'OPALA', then we would divide by the factorial of the number of repeating letters. That looks something like this:

$\frac{5!}{2!} = 60$

Hope this helped.

Will mark brainliest please help Debbie notices that the amount owed on her monthly heating bill varies inversely with the avera

Alekssandra [29.7K]

Answer:

The bill is $1837.5

Step-by-step explanation:

Given

$B = Bills$

$T = Temperature$

$B\ \alpha\ \frac{1}{T}$ --- The variation

T = 35; when B = 210

Required

Find B when T = 40

$B\ \alpha\ \frac{1}{T}$

Express as an equation

$B = \frac{k}{T}$

Make k the subject

$k = BT$

$k = 35 * 210$

$k = 7350$

When T = 40, we have:

$k = BT$

$7350 = B * 40$

Make B the subject

$B = \frac{7350}{4}$

$B = 1837.5$

What is the simplified form of the expression k^3(k7/5)^-5

saveliy_v [14]

The expression can be simplified as:

k^3(k7/5)^-5
= k^(3+-5) * (7/5)^-5
(Collecting the powers of k at one side and the constants at other side)
= k^-2 * (5/7)^5
(Solving thr integer powers)
= k^-2 * (3125/16807)

Round to the nearest whole number 3.713 divided by 0.413

babunello [35]

After the division, we get 8.99031476998. This rounds to <u>9</u> as a whole number, which is the answer.

When rounding to a whole number, the digits following the decimal decide what number it rounds to. If it is 0-4 it rounds to whatever the whole number currently is E.G.

8.1 would round to 8

But if its 5-9 it rounds to one above, like in our current case.

8.5 rounds to 9.

42.414 rounds to 42.

42.94149124 rounds to 43.
