All computers are on sale for 10% off the original price. If x is the original price of the computer, then the function that represents the price after only a 10% discount is: P(x) = x - 0.1x P(x) = 0.9x The function that gives the price, C, if only a $150 coupon is used is: C(x) = x - 150 Choose the composition function that gives the final sale price after a 10% discount is followed by a $150 coupon. C(P(x)) = 0.9x – 150 P(C(x)) = 0.9x – 150 C(P(x)) = 1.9x – 150 P(C(x)) = 1.9x – 150

Answers

Answer 1

Answer: so the original price is "x".

the discounted price by 10% is P(x) = 0.9x.

the price minus a $150 coupon is C(x) = x - 150.

so, if you go to the store, the item is discounted by 10%, so you're really only getting out of your pocket 90% of that, or 0.9x, but!!! wait a minute!! you have a $150 coupon, and you can use that for the purchase, so you're really only getting out of your pocket 0.9x - 150, namely the discounted by 10% and then the saving from the coupon.

C( P(x) ) = P(x) - 150

C( P(x) ) = 0.9x - 150

Answer 2

Answer:

C(P(x)) = 0.9x – 150 is the correct answer.

Can you solve 9 5/9 + 1 1/5

Answers

9 5/9 + 1 1/5

9 + 1 = 10

5/9 + 1/5 = 25/45 + 9/45 = 34/45

10 34/35 is the answer

8 5 /9 + 1 1/5

8 + 1 = 9. 5/9 + 1/5 = (5/9)*(5/5) + (1/5)*(9/9) = 25/45 + 9/45

= (25 + 9) /45 = 34/45

= 9 34/45

How many gallons are in 161.25 sq ft

There are none. "Square foot" is a unit of area, not volume.
Square feet are flat, and can't hold water.

If you meant to ask about 161.25 CUBIC feet, I can help you there:

PLEASE PLEASE HELP IM BEING TIMED The two-way table represents data from a survey asking students whether they plan to attend college, travel, or both after high school. A 4-column table with 3 rows. The first column has no label with entries travel, not travel, total. The second column is labeled college with entries 43, 24, 67. The third column is labeled not college with entries 10, 5, 15. The fourth column is labeled total with entries 53, 29, 82. Which is the marginal relative frequency for students who plan to attend college? Round the answer to the nearest percent. 18% 22% 35% 82%

Answers

Answer: 82%

Step-by-step explanation:

- - - - - - - - college - - not college - - - - total

Travel - - - - 43 - - - - - - - 10 - - - - - - - - 53

Not travel - 24 - - - - - - - 5 - - - - - - - - - 29

Total - - - - 67 - - - - - - - 15 - - - - - - - - - 82

Marginal relative frequency of students who plan to attend college:

(Number of students who plan to attend the college / Total number of the students)

Number of students who plan to attend college = 67

total number of students = 82

Marginal relative frequency = 67/82

= 0.8170731

= (0.8170731) * 100%

= 81.7% = 82%

The recommended dose of Vancocin® for a severe staphylococcal infectionis 40 mg/kg/day. The adult weighs 180 pounds and is to receive the
medication IV q6h (every six hours). How many mg can the adult receive
per day?

Answers

$180lb=81.6kg$

$(40 mg)/(1kg) = (xmg)/(81.6kg)$

$40 * 81.6 = x$

$3264 =x$

$3264mg$

$(24hr)/(6hr) = 4hr$

$3264*4$

$13056 mg/day$

Describe how you solved the following problem:I have a jar filled with $100 worth of quarters, nickels, and dimes.

I have the same amount of each type of coin. How many total coins do I have in my jar?

Answers

first you make sure you have all your variables using same measurement - cents (since it is the smallest)

$100 = 100*100 cents = 100,000 cents
1 quarter = 25 cents
1 nickel = 5 cent
1 dime = 10 cents

the test of your problem said that:
you have $100 in i don't know how many coins of quarters, nickels and dimes
100,000 = X * (25+5+10)

we have to find X:

100,000= X *(25+5+10)
100,000= X *40
X= 100,000/40
X = 2,500 coins
