Ray is purchasing a laptop that is on sale for 25% off. He knows the function that represents the sale price of his laptop is c(p) = 0.75p, where p is the original price of the laptop. He also knows he has to pay 8% sale's tax on the laptop. The price of the laptop with tax is f(c) = 1.08c, where c is the sale price of the laptop.Determine the composite function that can be used to calculate the final price of Ray's laptop by solving for f[c(p)].
f[c(p)] = 1.83p
f[c(p)] = 1.83cp
f[c(p)] = 0.81p
f[c(p)] = 0.81cp

Answers

Answer 1

Answer:

Answer: $f(c(p))=0.81p$

Step-by-step explanation:

Given: Ray is purchasing a laptop that is on sale for 25% off.

The function that represents the sale price of his laptop is $c(p) = 0.75p$ , where p is the original price of the laptop.

The percent of tax on laptop= 8%

The price of the laptop with tax is $f(c) = 1.08c$ , where c is the sale price of the laptop.

The composite function that can be used to calculate the final price of Ray's laptop will be:-

$f(c(p))=1.08(0.75p)\n\n\Rightarrow\ f(c(p))=1.08*0.75p\n\n\Rightarrow\ f(c(p))=0.81p$

Answer 2

Answer: Given:
c(p) = 0.75p
f(c) = 1.08c

f[c(p)] = 1.08*0.75p
f[c(p)] = 0.81p The 3rd option is my answer.

Johnathan has 2500 kg of sand delivered to a construction site every day. About how many tons of sand does he have delivered to the site after 4 weeks? 1 ton≈907.2 kg A) 2.5 tons
B) 19.3 tons
C) 77.2 tons
D) 324,000 tons

Answers

The answer is C.

Since every week is made up of 7 days, then four weeks will have;

2500 * 7 * 4 = 70,000 kg delivered

If 907.2kg = 1 ton, then to convert 70,000 kg to tons;

70,000/907.2 = 77.16049.....

We round off to 77.2 tons

Answer:

the answer C) 77.2 tons

0.18

Hope this helps! （づ￣3￣）づ╭❤～

Step-by-step explanation:

Answer:

0.18

Step-by-step explanation:

18 divided by 100 is 0.18 18 divided by 1000 is 0.018

you move the decimal to the left when you divided a number by ten how many zeros is how many times you move the decimal. every number is a decimal like if you have a number 20 it actually looks like 20. so when you divide it by a 10 or 100 to move the decimal to the left the same number of zeros in 100 so that would be 0.20 hope you understand

Which event is considered neither likely nor unlikely?A. rolling a number greater than one on a six-sided number cube
B. rolling a 1 on a six-sided number cube
C. getting heads when flipping a coin
D. choosing a X, Y, or Z from a bag containing all letters in the alphabet

Answers

Hey there

The answer is D.
choosing a X, Y, or Z from a bag containing all letters in the alphabet.

There are 46 different alphabets.
You have 3/46 chances
6% out of 100 of picking those letters

A.) it is possible to roll a number greater than 1 on a six sided number cube. - So it is likely.

B) It is possible to roll a 1. - So it is likely.

C) It is possible to get a heads when flipping a coin. - So it is likely.

D) It is possible to choose a X, Y or Z from the alphabets. - So it is likely.

Am sorry did not see any one that is neither likely nor unlikely.

There is likelihood in each of the Event, but to some varying degree.

I hope this helps.

The figure is made up of a square and a rectangle. Find the area of the shaded region.

Answers

Answer:

40 square metres

Step-by-step explanation:

The shaded region is of a triangle, whose area is denoted by: A = (1/2) * b * h, where b is the base and h is the height.

Since the left figure is a square with side lengths 10, we know that the height of the triangle is also 10 metres. The right figure is a rectangle with length 4. Since the total base length of the entire figure is 18 and the base of the square is 10, then the width of the rectangle is 18 - 10 = 8 metres.

This width is also the base of the triangle, so b = 8.

Now plug these values into the equation:

A = (1/2) * b * h

A = (1/2) * 8 * 10 = (1/2) * 80 = 40

The area is 40 square metres.

Answer:

40 m²

Step-by-step explanation:

Area of any triangle:

½ × base × height

base = 18 - 10 = 8

height = 10
