Simplify the following:
k - 2 (k - (2 - k)) - 2
-(2 - k) = k - 2:
k - 2 (k + k - 2) - 2
Grouping like terms, k + k - 2 = (k + k) - 2:
k - 2 ((k + k) - 2) - 2
k + k = 2 k:
k - 2 (2 k - 2) - 2
-2 (2 k - 2) = 4 - 4 k:
k + 4 - 4 k - 2
Grouping like terms, k - 4 k - 2 + 4 = (4 - 2) + (k - 4 k):
(4 - 2) + (k - 4 k)
k - 4 k = -3 k:
-3 k + (4 - 2)
4 - 2 = 2:
Answer: 2 - 3 k

There are 5.2 x 10^5 words in the English dictionary. What is the average number of words recorded under each of the 26 letters?

alexira [117]

Answer:

2.0*10^4

Step-by-step explanation:

$5.2 *10^5$ words

26 categories

$\frac{5.2 *10^5}{26} =\frac{520 000}{26} =20 000$

$2.0*10^4$

so there is an average of 2.0*10^4 words per letter

Which side lengths form a right triangle 30 POINTS!! I DONT HAVE MUCH TIME

Virty [35]

Answer:

To solve this problem, we can use Pythagorean theorem, it tells us that the square of the hypotenuse is equal to the sum of the square of the other two sides.

When we look at these side lengths, we can see that only the second answer is suitable because from the lengths, we can predict that 13 is the length of the hypotenuse, 5 is the length of the shorter leg and 12 is the length of the other leg, and when you actually calculate it, the result is correct as well:

5² + 12² = 25 + 144 = 169

13² = 169

So the answer is B

There are a number of ways you can write the piecewise function. Here is one of them:

$p(t)=\left\{\begin{array}{rcl}7t&\mbox{for}&t\leq40\\10.5t-140&\mbox{for}&t>40\end{array}\right.$

It could also be something like
p(t) = 7t + 3.50×max(0, t-40)
where the max(x,y) function returns the larger of x or y.

Finger [1]

let x be the number of adults
let y be the number of child

3.5 x + 2.25 y = 50

x+ y =20 y = 20 - x

3.5 (20-y ) + 2.25 y = 50

70 - 3.5 y +2.25y =50

70 -1.25 y = 50

y = 16

and x = 4
