Answers

Answer 1
Take $25 times .12 which is 3
Then take 25-3 which is $22
Your sale price is $22
Answer 2

$22 is the sale price when the Original price is $25 and Markdown is 12%.

What is Percentage?

percentage, a relative value indicating hundredth parts of any quantity.

The original price is twenty five.
The markdown is twelve percentage.

We have to find the sale price of the product.

Let us convert 12% to the decimal value by dividing 12 with 100

12/100=0.12

Now multiply 0.12 with 25

0.12×25=$3

Now subtract 3 from 25

25-3=22

Hence, $22 is the sale price when the Original price is $25 and Markdown is 12%.

You have a 64 foot of fencing. What are the dimensions of the rectangle of the greatest area you could enclose?

Answers

In a rectangle, opposite sides are congruent.
Let one side have length x.
The opposite side also has length x.
The lengths of these two sides add to 2x.
The lengths of all 4 sides add to 64, so the lengths of the other 2 sides
add up to 64 - 2x. Each side measures 32 - x.

The rectangle has sides of length x and 32 - x.

The area of the rectangle is

A = LW

A = x(32 - x)

A = 32x - x^2

y = 32x - x^2 is a parabola that opens downward.
The maximum value of the parabola is the vertex on top.

32x - x^2 = 0

(32 - x)x = 0

32 - x = 0 or x = 0

x = 32 or x = 0

Since the parabola is symmetric with respect to the vertical axis, the vertex has x-coordinate 16.

At x = 16, you get maximum area.

Two opposite sides measure 16 ft each.
32 - x = 32 - 16 = 16
The other two opposite sides also measure 16 ft.

Since all sides turned out to have length 16 ft, the rectangle is a square.

Answer: The maximum area is enclosed by a square with side 16 ft.

The expression 12g12g12, g gives the number of kilometers a car can travel using ggg liters of gasoline. How far can this car travel on 5 \dfrac125 2 1 ​ 5, start fraction, 1, divided by, 2, end fraction liters of gasoline?

Answers

Answer:
The car can travel 66 miles using 5.5 liters of gasoline

Explanation:
We are given that:
The expression 12*g is used to evaluate the number of miles the car can travel using g liters of gasoline.
Therefore:
miles = 12*g

Now, we are given that the liters of gasoline = 5[tex] \frac{1}{2} [/tex] = 5.5 liters.
To get the number of miles, all we have to do is substitute with the given liters in the above expression as follows:
miles = 12*g
miles = 12 * 5.5
miles = 66 miles

marta ha comprado una bicicleta que costaba 280 € pero le han hecho una rebaja del 15°/• cuanto ha pagado

Answers

Marta has paid €238.

The original price was €280, but the price was discounted by 15%.  

15% = 15/100 = 0.15.
15% of 280 is 0.15(280) = 42

This means the price was cut by €42.

What is the perimeter of AEB

Answers

Answer:
18.5 ft

Explanation:
part (a): getting the value of AE:
The two triangles AEB and DEF are similar. Therefore, we can make use of the similar proportionality as follows:
AE / DE = BE / FE
Now, we have:
AE is the unknown we want to find
DE = AE + 2
BE = 7.8 ft
FE = 7.8 + 2.4 = 10.2 ft

Substitute in the above relation and get the value of AE as follows:
AE / DE = BE / FE
AE / (AE+2) = 7.8 / 10.2
10.2 AE = 7.8 AE + 15.6
2.4 AE = 15.6
AE = 6.5 ft

Part (b): getting the perimeter of AEB:
perimeter = AE + EB + AB
perimeter = 6.5 + 7.8 + 4.2
perimeter = 18.5 ft

It's easiest to start with the point-slope form of an equation, [tex]y-y_1=m(x-x_1)[/tex], where m is the slope and [tex](x_1, y_1)[/tex] is the point given.

We have m = 3, [tex]x_1 = 5[/tex], and [tex]y_1 = 10[/tex].

We plug in these values to get
[tex]y-10=3(x-5)[/tex].

We now rearrange to get this into slope-intercept form, [tex]y=mx+b[/tex], by solving for y.

[tex]y=3(x-5)+10\\y=3x-15[/tex]
Answer:
y = 3x - 5

Explanation:
The equation of the line in slope-intercept form is:
y = mx + c
where:
m is the slope
c is the y-intercept

We are given that the slope is 3. Therefore, the equation now is:
y = 3x + c

Now, we need to get the value of c. To do so, we will substitute with the given point (5,10) in the equation and solve for c as follows:
y = 3x + c
10 = 3(5) + c
10 = 15 + c
c = 10 - 15
c = -5

Based on the above, the equation of the line is:
y = 3x - 5

The weight of a person on or above the surface of the earth varies inversely as the square of the distance the person is from the center of the earth. A particular person weighs 192 pounds on the surface of the earth and the radius of the earth is 3900 miles. Determine the equation that relates weight, W, to the distance from the center of the earth, d, for this person.
Answer choices on picture.

Answers

The question tells us that the weight of a person varies with the square of their distance to the center of the Earth.

Weight = 192 pounds
Radius of the earth = 3900  miles 

Let's introduce the constant, k
192 = [tex] \frac{k}{3900 ^{2} } [/tex]
k = 192 * 3900²
k = 192 * 15,210,000
k = 2,290,320,000

Putting the constant k back into the equation, W = [tex] \frac{k}{d ^{2} } [/tex]

W = [tex] \frac{2,290,320,000}{d ^{2} } [/tex]

(OPTION D)

The weight of a person on or above the surface of the earth varies inversely as the square of the distance the person is from the center of the earth.

The distance the person is from the center of the earth: d

W=K/d^2

W=192 pounds, d=R: Radius of the earth=3900 miles
Replacing in the equation above:
192=K/3900^2

Solving for K:
192=K/15,210,000
192*15,210,000=K
2,920,320,000=K
K=2,920,320,000

Then the equation is:
W=K/d^2 and K=2,920,320,000

W=2,920,320,000/d^2

Answer: Option d. W=2,920,320,000/d^2

Canada is the king of the doughnut world, as it has more doughnut shops per capita than any other country in the world. Tim Hortons, the most popular doughnut joint in Canada, had 3660 locations in Canada in 2015. If the population of Canada was approximately 35.75 million citizens in 2015, what was the number of Tim Hortons stores per capita in Canada in 2015?
Express your answer in scientific notation rounded correctly to three decimal places.

Answers

The correct answer is 1.024 x 10^-4.

Per capita means the number of schools per person. There are more people than stores, so the number must be lower than 1.

To find the rate, we divide the total number of stores by the population.

3660 / 35750000 = .0001024 = 1.024 x 10^-4

Answer:

Number of Tim Hortons stores per capita is [tex]1.024\times 10^{-4}[/tex]

Step-by-step explanation:

Canada is having more doughnut shops per capita than any other country in the world means availability of Horton's store per person are more.

Number of Hortons stores in Canada = 3660

Population of Canada in 2015 = 35.75 million

In scientific notation population = [tex]35.75\times 10^{6}[/tex]

Now stores per person = [tex]\frac{3660}{35.75\times 10^{6}}[/tex]

(To calculate stores per capita we will divide number of stores by population of Canada)

Stores per capita = [tex]102.377\times 10^{-6}=1.024\times 10^{-4}[/tex]

So the answer is [tex]1.024\times 10^{-4}[/tex]

Sabra joins a cooking club for $8.50 and pays $6.25 each month. She also joins a movie club for $12 and pays $3.75 each month. Write an expression that represents the total amount of money Sabra spends on both clubs after m months. Then enter the simplified expression in the boxes.

Answers

Answer: The simplified express is 10m + 20.5 where m represents the total number of months.

To start we can write the following two expressions for her expenses.
8.5 + 62.5m   and     12 + 3.75m

Then, adding the two expressions together will give us a combined expression of:  10m + 20.5

Total amount of money Sabra spends on both clubs = 20.50 + 10m

Amount paid to join the cooking club = $8.50

Monthly payment at the cooking club = $6.25

Payment for m months at the cooking club = 6.25m

Total money paid at the cooking club = 8.50 + 6.25m

Amount paid to join the movie club = $12

Monthly payment at the movie club = $3.75

Payment for m months at the movie club = 3.75m

Total money paid at the movie club = 12 + 3.75m

Total amount of money Sabra spends on both clubs = Total money paid at the cooking club + Total money paid at the movie club

Total amount of money Sabra spends on both clubs = 8.50 + 6.25m + 12 + 3.75m

Total amount of money Sabra spends on both clubs = 20.50 + 10m
