A friut stand sells watermelons during the summer. The revenue for selling x watermelons is given by f(x)=2.5x. The team's profit is $25 more than 60% of the revenue for selling x watermelons. Write a funcction g to model the profit. Then find the profit for selling 44 watermelons.

Answers

Answer:

$91

Step-by-step explanation:

f(x) = 2.5 x

$25 more would + $25 to the function

60% = .6

Revenue is f(x) = 2.5x  which we have to multiply by the .6

g(x) = $25 + .6 (2.5 x)

If we have 44 watermelons then we plug in 44 for x

x = 44

g(x) = $25 + .6 (2.5*44)

g(x) = $25 + .6 (110)

g(x) = 25 + 66

g(x) = $91

The profit is $91

The students at Woodward Elementary voted for a school mascot. The falcon won with 58 of the votes and the eagle came second with 13 of the remaining votes. If 536 students voted for a mascot, how many students voted for the eagle?

Answers

Answer:

67 students voted for the eagle

Step-by-step explanation:

The students at Woodward Elementary voted for a school mascot. The falcon won with 5/8 of the votes and the eagle came second with 1/3 of the remaining votes. If 536 students voted for a mascot, how many students voted for the eagle

Total students who voted = 536

Falcon won with 5/8 of the votes

5/8 of 536

=5/8 × 536

= 2,680/8

= 335 votes

Falcons won with 335 votes

Remaining votes = Total votes - falcons votes

= 536 - 335

= 201 votes

There are 201 votes remaining

Eagle came second with 1/3 of the remaining votes

1/3 of the remaining votes

= 1/3 × 201

= 201/3

= 67 votes

67 students voted for the eagle

Solve the equation below for the variable "x". *
- 2x + 10 = 8

Answers

Answer:

x = 1

Step-by-step explanation:

Subtract 10 from 8 to get -2. Then divide -2x by itself so it will cancel out. Whatever you do to one side of the equation, do to the other so divide -2 by -2 to get your answer of 1

Answer:

[tex]x=1[/tex]

Step-by-step explanation:

[tex]-2x+10=8[/tex]

So let's solve this equation.

So first, we're gonna have to minus 10 from both sides of the equation.

[tex]-2x+10-10=8-10[/tex]

Now let's turn this into a fraction and divide by -2

[tex]\frac{-2x}{-2} =\frac{-2}{-2}[/tex]

[tex]x=1[/tex]

So now we have our answer!

Making a round trip from Fairview to Cartersville, a distance of 20 miles, a pilot faces 30 mph head wind one way and 30 mph tail wind on the return trip. The return trip takes 45 minutes less than the outbound journey. Find the speed of the plane in still air

Answers

Answer:

50mph

Step-by-step explanation:

Given the following :

Distance (d) of journey = 20 miles

Wind speed = 30mph head wind in one way, 30mph tail wind in the other direction

Return trip = 45 minutes (45/60 = 0.75 hour) less Than the outbound journey

Speed of plane in still air

Outbound trip :

Velocity = Distance / time

Time = distance / velocity

Velocity = (v - 30) due to head wind

Return Velocity (V +30) due to tail wind

Outbound time = return distance

20 / (v - 30) = 20 / (v +30) + 0.75

20v + 600 = 20v + 0.75v^2 + 22.5v - 600-22.5v-675

600 = 0.75v^2 - 1275

0.75v^2 = 1875

v^2 = 1875/ 0.75

v^2 = 2500

v = sqrt(2500)

v = 50mph

A cyclist rides his bike at a rate of 15 miles per hour. what is this rate in miles per minute? how many miles will the cyclist travel in 20 minutes? do not round your answers.

Answers

Answer:

15 miles/hour = 0.25 miles/minute

The cyclist would have traveled 5 miles in 20 minutes.

Step-by-step explanation:

15 miles per hour is written as

15 miles/hour

To convert 15 miles/hour to miles/minute

From 1 hour = 60 minutes

∴ 15 miles/hour = 15 miles/ 60 minutes

= (15/60) miles/minute

= 0.25 miles/minute

To calculate how many miles the cyclist will travel in 20 minutes

That is, Time, t = 20 minutes

Velocity, v = 15 miles/hour = 0.25 miles/minute

Distance, s = ??

From,

[tex]Velocity = \frac{Distance}{Time}\\[/tex]

∴[tex]Distance = Velocity[/tex] × [tex]Time[/tex]

[tex]Distance = 0.25 miles/minute[/tex] × [tex]20 minutes[/tex]

[tex]Distance = 5 miles[/tex]

Hence, The cyclist would have traveled 5 miles in 20 minutes.

if a cone and a cylinder have the same radius and the perpendicular height of the cone is twice that of a cylinder find the ratio of the volume​

Answers

Answer:

2/3

Step-by-step explanation:

h = height of the cone

Vcone = πr²h/3

H = h/2 = height of the cylinder

Vcylinder = πr²H = πr²h/2

Vcone/Vcylinder = (πr²h/3)/(πr²h/2)

= πr²h/3 x 2/πr²h

= 2/3

Answer:

2/3

Step-by-step explanation:

h = height of the cone

Vcone = πr²h/3

H = h/2 = height of the cylinder

Vcylinder = πr²H = πr²h/2

Vcone/Vcylinder = (πr²h/3)/(πr²h/2)

= πr²h/3 x 2/πr²h

= 2/3

Brown Squirrels can carry 2 acorns at a time. Gray Squirrels can carry 3 acorns at a time. Black Squirrels can carry 5 acorns at a time. Suppose the three squirrels all wanted to store acorns for the winter. Depending on how motivated each squirrel was they would end up with different amounts. For instance, suppose the Brown Squirrel took 4 trips, the Gray Squirrel took 2 trips and the Black Squirrel took 2 trips. The Brown Squirrel would end up with 8 acorns, the Gray Squirrel would have 6 acorns and the Black Squirrel would have 10 . Between them they took every one of the 24 acorns. How Many Ways "Show Them" can the squirrels get all 24 acorns. (One can get all of them, and the others get none

Answers

Answer:

There are five ways in which the squirrels can get all 24 acorns.

Step-by-step explanation:

The information provided is:

Brown Squirrels can carry 2 acorns at a time.Gray Squirrels can carry 3 acorns at a time. Black Squirrels can carry 5 acorns at a time. The three squirrels all wanted to store acorns for the winter. Between them they took every one of the 24 acorns.

Each squirrel makes at least one trip.

Consider the table for the total number of trips the squirrels make get all 24 acorns:

Brown (2)       Gray (3)       Black (5)               Total no. of acorns

    1                     4                  2               (1 × 2) + (4 × 3) + (2 × 5) = 24    

    2                     5                  1               (2 × 2) + (5 × 3) + (1 × 5) = 24    

    3                     1                  3               (3 × 2) + (1 × 3) + (3 × 5) = 24    

    4                     2                  2               (4 × 2) + (2 × 3) + (2 × 5) = 24    

    5                     3                  1               (5 × 2) + (3 × 3) + (1 × 5) = 24    

Thus, there are five ways in which the squirrels can get all 24 acorns.

Answers

Answer:

Total area of the composite figure = 129.1 square units

Step-by-step explanation:

Area of the figure attached = Area of semicircle + Area of the rectangle

Since area of the semicircle = [tex]\frac{1}{2}\pi r^{2}[/tex]

where 'r' = radius of the circle

Area of the semicircle = [tex]\frac{1}{2}\pi (4)^{2}[/tex]

                                     = 8π

                                     = 25.1 square units

Area of the rectangle = Length × width

                                    = 13 × 8

                                    = 104 square units

Total area of the composite figure = 25.1 + 104

Ellie runs 5/6 mile in 10 minutes. What is Ellie's speed in miles per minute?​

Answers

Answer:

1/12 mi/min = 0.083 mi/min

Step-by-step explanation:

From the question given above, we obtained the following information:

Distance (d) = 5/6 mile

Time (t) = 10 mins

Speed (S) =?

Speed is simply defined as the rate of change of distance moved with time. It can be represented mathematically by the following equation:

Speed (S) = Distance (d) / time (t)

S = d/t

With the above formula, we can calculate Ellie's speed as follow:

Distance (d) = 5/6 mile

Time (t) = 10 mins

Speed (S) =?

S = d/t

S = 5/6 ÷ 10

S = 5/6 × 1/10

S = 5/60

S = 1/12 mi/min = 0.083 mi/min

Therefore, Ellie's speed is 1/12 mi/min.

Ellie speed in miles per minute is 1 / 12

Speed:

Speed is a scalar quantity with only magnitude and no direction. Speed measures how fast an object is in motion.

Speed is represented mathematically as follows:

speed = distance /time

Ellie covers 5/6 miles in 10 minutes. Therefore,

distance = 5/6 miles

time = 10 minutes

Speed = [tex]\frac{\frac{5}{6} }{10}[/tex] = [tex]\frac{5}{6}[/tex] ×[tex]\frac{1}{10}[/tex] = [tex]\frac{5}{60}[/tex] = [tex]\frac{1}{12}[/tex] miles per minutes
