The number of ways 6 different objects can be arranged in a row is given by 6! = 6 x 5 x 4 x 3 x 2 x 1 = 720

The number of ways 4 different objects can be arranged in a row is given by 4! = 4 x 3 x 2 x 1 = 24

Therefore, the number of ways which Travis can order his books more than that of Kelly is given by 720 - 24 = 696.

jeni works from 8:00-3:15 three days in a row, only taking a half-hour unpaid lunch break each day. if she is paid $15 per hour,
enyata [817]

Jeni gets paid $ 303.75 for 3 days

<em><u>Solution:</u></em>

Given that,

Jeni works from 8:00-3:15 three days in a row

<em><u>Find the number of hours between 8 : 00 to 3 : 15</u></em>

8 : 00 to 3 : 15 = 7 hours 15 minutes

She is taking half-hour unpaid lunch break each day

7 hours 15 minutes - half an hour = 6 hours 45 minutes

So, she works for 6 hours 45 minutes for each three days

6\ hours\ 45\ minutes = 6 + \frac{45}{60} = 6 + 0.75 = 6.75\ hours

She is paid $15 per hour

<em><u>Therefore, total earnings for 3 days is given as:</u></em>

Total\ Earnings = 3 \times 15 \times 6.75\\\\Total\ Earnings = 303.75

Thus she gets paid $ 303.75 for 3 days

If anybody now this pls help my homework due TOMORROW
Nezavi [6.7K]

Answer:

<u><em>Part A:</em></u> D. y = (x + 1)(x+3)\\

<u><em>Part B:</em></u> C. 3x(x-3) = 0\\

Step-by-step explanation:

For part A) we just have to plug in 0 for x and solve for y until we find the equation that says 3 is the value for y when x is 0. For purposes of speeding up the process the correct answer is D. I will show how to check for it now.

The equation: y = (x + 1)(x+3)

Now plug in 0 for x.

y = (0 + 1)(0+3)\\

Now solve.

y = (1)(3)

y = 3

This proves that this is the correct answer.

For part B) we just have to plug in the give values for x separately and check for each value of x that it equals 0. For the purpose of speeding up the process the correct answer is C. I will show how to check for it now.

The equation: 3x(x-3) = 0

Now plug in x for 0 and solve:

3* 0 (0-3) = 0\\

0(-3) = 0\\

0 =0\\

This equation is true, now we check for the other value of x, 3.

3*3(3-3) = 0\\

9(0) = 0\\

0 =0\\

This is also true so that means this is the correct answer.
