Answer:

<h3>1 gallon of paint can cover 60 square feet of wall.</h3>

Step-by-step explanation:

We are given that 2 1/2 gallon of paint can cover 150 square feet of wall.

We need to find the the number of square feet that 1 gallon of paint can cover.

In order to find the number of number of square feet that 1 gallon of paint can cover, we just need to divide 150 square feet by 2 1/2 gallon.

2 1/2 gallon in decimal form could be written as 2.5 gallons.

Dividing 150 square feet by 2.5 gallon, we get

\frac{150}{2.5}=60

<h3>Therefore, 1 gallon of paint can cover 60 square feet of wall.</h3>

Given f(x) = 2(4 – x)2, what is the value of F(15)? Record your answer and fat in the bubbles on your anser document​
kari74 [83]

Answer:

f(15) = 242

Step-by-step explanation:

Step 1: Define

f(x) = 2(4 - x)²

f(15) = x = 15

Step 2: Substitute and Evaluate

f(15) = 2(4 - 15)²

f(15) = 2(-11)²

f(15) = 2(121)

f(15) = 242

A manufacturer has been selling 1400 television sets a week at $450 each. A market survey indicates that for each $21 rebate off
GuDViN [60]

Correct question is;

A manufacturer has been selling 1400 television sets a week at $450 each. A market survey indicates that for each $21 rebate offered to a buyer, the number of sets sold will increase by 210 per week

A) Find the demand function (price p as a function of units sold x).

p(x)=______

(B) How large a rebate should the company offer the buyer in order to maximize its revenue?

$=_____

Answer:

A) p(x) = (-1/10)x + 590

B) Rebate = $170

Step-by-step explanation:

A) We are told that p(x) is the demand function and x is the number of TV sets sold per week.

Now, since for each $21 rebate offered, the number of sets sold increases by 210 per week, it means that the slope here of this demand function is; m = -21/210 = -1/10

Now, he has been selling 1400 TV sets a week at $450 each. This means; p(1400) = $450

Thus, the demand function will be;

p(x) - 450 = (-1/10)(x - 1400)

Expanding the RHS;

p(x) - 450 = (-1/10)x + 140

Add 450 to both sides to get;

p(x) = (-1/10)x + 140 + 450

p(x) = (-1/10)x + 590

B) Formula for revenue is;

R = price × quantity sold

Our demand function is p = (-1/10)x + 590

Making x the subject, we have;

x = 5900 - 10p

x is quantity sold.

Thus,

R = p(5900 - 10p)

R = 5900p - 10p²

Maximum price will occur at dR/dP = 0

Thus;

dR/dP = 5900 - 20p

At dR/dP = 0,we have;

20p = 5900

p = 5900/20

p = $280

Thus, rebate = 450 - 280 = $170

Omar has 2-5/8 cups of dough to make dumplings. If he uses 3/16 cup of dough for each dumpling, how many whole dumplings can Oma
Arte-miy333 [17]

Answer:

The number of whole dumpling does Omar make is 14 .

Step-by-step explanation:

Given as :

The number of cups does Omar has to make dumplings = x = 2\dfrac{5}{8}

i.e x = \dfrac{16 + 5}{8}

or, x =  \dfrac{21}{8}

Again

The number of cups uses for each dumpling = y =  \dfrac{3}{16}

i.e y = \dfrac{3}{16}

Let The number of whole dumpling does Omar make = z

So,  number of whole dumpling does Omar make = \dfrac{\textrm number of cups does Omar has to make dumplings}{number of cups uses for each dumpling }

Or, z = \dfrac{x}{y}

Or, z = \frac{\frac{21}{8}}{\frac{3}{16}}

Or, z = \frac{21\times 16}{8\times 3}

∴  z = 7 × 2

i.e z = 14

So, The number of whole dumpling does Omar make = z = 14

Hence, The number of whole dumpling does Omar make is 14 . Answer
