As a fundraiser, the band is selling cookies. The cost to make each cookie can be written as c(x) = 0.25x + 0.5 and the functions that represents the amount they sell the cookie for can be written as s(x) = 2x. What function represents the profit, P(x), for each function?

The profit it's the money that you make minus the money that you sell. So
P(x) = s(x) - c(x)
P(x) = (2x) - (0.25x + 0.5)
P(x) = 2x - 0.25x - 0.5
P(x) = 1.75x - 0.5

QUESTION POSTED AT 22/02/2020 - 09:23 PM

WORTH 10 POINTS! Mara decides to plot her neighborhood on a coordinate plane. She plots her house at the point (0,0), her school is located at (0,8), the library at (3,8), and the softball field is at (3,0). One day she decides that after school she will run by the library to grab a book, and then head to softball practice and then back home. How far on the coordinate plane does she travel starting at home that morning? Leave your answer in units. A) 11 units B) 14 units C) 19 units D) 22 units

Answer:

Option: D is the correct answer.

D) 22 units.

Step-by-step explanation:

Her home is located at: (0,0)

School at (8,0)

Library at (3,8)

and softball field is located at (3,0) on the coordinate plane.

Now, that morning she starts from home then goes to school then after school she goes to Library and then after library she goes to softball field and returns back home.

Home→ school → Library → Softball field → Home.

This means that she covers the boundary of the rectangle that is formed by the location of the points.

This means in order to find the total distance she traveled we need to find the perimeter of the rectangle.

Length of One side of rectangle(a)= 8 units.

Length of the other side of rectangle(b) = 3 units.

Hence,

Perimeter of rectangle= 2(a+b)

                                    = 2(8+3)

                                   =2×11

                                   = 22 units.

Hence, the total distance she traveled is:

                       22 units.

An oil storage tank is a cylinder 30 feet high. The base of the tank is a circle with a diameter of 50 feet. When full, how many gallons are in the tank? 1 gallon equals approximately 0.13 cubic feet.

Answer with Step-by-step explanation:

An oil storage tank is a cylinder 30 feet high.

The base of the tank is a circle with a diameter of 50 feet.

The water in tank will be equal to the volume of the tank.

We know that volume of cylinder is given by:

V=πr²h

where r is the radius and h is the height

Here, r=25 feet (since radius=diameter/2)

and h=30 feet

Volume=3.14×25×25×30

            =58875 cubic feet

1 gallon=0.13 cubic feet

1 cubic feet=1/0.13 gallon

58875 cubic feet=58875/0.13 gallons

                            = 452884.62 gallons

Hence, water in tank equals:

452884.62 gallons

A hollow crystal ball is made of glass that is 3 cm thick. The ball has a radius to the outside surface of 8 cm. What is the approximate volume of glass used to make the ball? Use 3.14 to approximate pi. a 113.0 cm³ b 523.3 cm³ c 1620.2 cm³ d 2143.6 cm³

Answer:

The Correct Answer is 523.3 cm^3

Step-by-step explanation:

A hollow crystal ball is made of glass that is 3 cm thick. The ball has a radius to the OUTSIDE surface of 8 cm, so 8 - 3 = 5.

v = 4/3 pi (5)^3

v = 4/3 pi (125)

v = 523.3333333

The volume of the hollow 3 cm thick crystal ball is approximately 523.3 cm^3

Matt is making cookies. He adds 3 over 4 cup of sugar to a bowl. He then removes two 1 over 8 cups of sugar. Which of the following best explains the amount of sugar left in the bowl? A 4/8 because 3/4-2*(1/8)=3/4-3/8. B 4/8 because 3/4-2*(1/8)=3/4-2/8

Answer:

 Option B) is the correct answer.        

Step-by-step explanation:

We are given the following information in the question.

Amount of sugar added to bowl = \displaystyle\frac{3}{4}

Amount of sugar removed = 2\times \displaystyle\frac{1}{8}

In order to calculate total amount of sugar = \text{Amount of sugar added in the bowl} - \text{Amount of sugar removed from the bowl}

= \displaystyle\frac{3}{4} - (2\times \displaystyle\frac{1}{8} ) \\\\= \displaystyle\frac{3}{4} - \displaystyle\frac{2}{8}\\\\= \displaystyle\frac{6}{8} - \displaystyle\frac{2}{8}\\\\= \displaystyle\frac{4}{8}

Thus, Option B) is the right interpretation.

An auction website charges $1 for a bid. The bidding starts at 1¢ and goes up 1¢ at a time. A television that is worth $2000 is won, on average, with a bid of $160. You make one bid at random. Find the expected value of the outcome of the bid. (Write as an exact decimal, with a negative sign, if necessary.)

This is fairly complex, but looks like fun. 
So first lets count how many bids are made till the bidding goes up to 160.
That is 100*160=16000
How much will be your random bid. Each bid has equal chance so it is the avarge of all bids. (1cent + 160dollars)/2 = 80dollars (rounded)
What is your chance of winning: 1 bid wins out of 16000 so 1/16000.
When you win your profit is 2000-80dollars=1920
1920/16000= 0.12 dollars 
You entering the bidding costs 1 dollar and your average win is 0.12
This the outcome is 0.12-1=-0.88 dollars

Use 3.14 for π to estimate the area of a circle.the diameter is 24.4. Round your answer to the nearest hundredth if necessary

Answer:  The required area of the given circle is 467.36 sq. units.

Step-by-step explanation:  We are given that the diameter of a circle is 24.4 units and the value of π is 3.14.

We are to find the area of the circle.

We know that

the AREA of a circle with length of the radius r units is given by

A=\pi r^2.

Since the diameter of the given circle is 24.4 units, so its radius will be

r=\dfrac{24.4}{2}=12.2~\textup{units}.

Therefore, the AREA of the circle will be

A=\pi r^2=3.14\times(12.2)^2=3.14\times 148.84=467.3576~\textup{sq. units}.

Rounding to nearest hundredth, we get

A = 467.36 sq. units.

Thus, the required area of the given circle is 467.36 sq. units.

QUESTION POSTED AT 22/02/2020 - 04:51 PM

Ebert used to make $22 an hour, but got a 10% raise. How much more will he make in a 40 work week with the raise? Give steps!

Answer:

He will make $88 more per week with the raise.

Step-by-step explanation:

Since we are asked about the increment, we focus on finding the amount of money he has gained from raise, once we have that we can  find the total amount gained per week, knowing he works 40 hours per week.

Raise increment in dollars.

Since he has  a raise of 10%, we can find the value of 10% of $22 first.

\text{ Increment per hour } =  \$22(0.1)

Notice that we have to multiply to find that increment and we are writing 10% in decimal form, that is 0.1, so we get:

\text{ Increment per hour } =  \$2.2

Total amount gained per week

We know that he makes now $2.2 per hour, so  in  40 hours, he will make:

\text{ Increment per week } = \$2.2\text{ per hour} \times 40 \text{ hours per week}

That give us

\text{ Increment per week } = \$ 88

Thus the increment per week is $88.
