Paul woke up for school at 7:30 AM. He took 14 minutes to get ready, 9 minutes to

scZoUnD [109]

Answer:

$\huge\boxed{\sf 8:32\ AM}$

Step-by-step explanation:

Woke up = 7:30 AM

<u>Time to:</u>

Get ready = 14 min
Finish breakfast = 9 min
Commute to school = 39 min

<u>Altogether:</u>

= 14 + 9 + 39 min

<h3>= 62 minutes </h3>

(As we know that, 1 hour = 60 minutes)

So,

<h3>62 minutes = 1 hour 2 minutes</h3>

<u>Time he reached the school:</u>

7 hr 30 min + 1 hr 2 min

Combine like terms

7 hr + 1 hr + 30 min + 2 min

<h3>8 hr + 32 min</h3>

OR

<h3>8:32 AM</h3>

$\rule[225]{225}{2}$

If f(x)=x^2−8x and g(x)=−12x^2 what is g(f(−4))?

Korolek [52]

Answer:

-27648

Step-by-step explanation:

In this problem, we are looking for the <u>function of </u><u><em>g</em></u><u> in terms of the function </u><u><em>f</em></u><u>. </u>Simply put, we just <u>replace the variable </u><u><em>x</em></u><u> in the function </u><u><em>g</em></u><u> with </u><u><em>f(-4)</em></u>.

Step 1, writing g(f(-4)):

$g(f(-4))=-12(f(x))^2$

Great! Let us substitute f(x) with the given expression.

Step 2, substituting and simplifying:

$\\g(f(-4))=-12(x^2-8x)^2\\g(f(-4))=-12((-4)^2-8*(-4))^2\\g(f(-4))=-12(16+32)^2\\g(f(-4))=-12*2304\\g(f(-4))=-27648$

g(f(-4) is $\fbox{-27648}$ .

West and Company uses the LIFO method to calculate inventory values. Their beginning inventory consisted of 200 units at a cost

nirvana33 [79]

The total inventory is 200 + 300 + 400 + 100 = 1000. If 300 units remained, the we calculate the cost of the 700 sold via LIFO. These 700 units include the 100 units at $12.00, the 400 units at $11.00, and 200 units at $10.00 (out of the 300 purchased). This is a total cost of 100*12 + 400*11 + 200*10 = 1200 + 4400 + 2000 = $7600.
