If the original price of a pair of shoes is $80 but a sign above the shoes reads “Sale - 20% discount”, then what price would a costumer pay for the shoes (excluding tax)?
A.) 64
B.) 6
C.) 16
D.) 80
E.) 60

Answer:

The new amount is $86.10

Step-by-step explanation:

First we find the increase

82*5%

82 *.05

4.1

Next we add the increase to the original amount

82+4.1

86.10

The new amount is $86.10

♫ - - - - - - - - - - - - - - - ~Hello There!~ - - - - - - - - - - - - - - - ♫

➷ First, you need to find what 5% of 82 is.

82*5%=4.1

Now, you need to add 4.1 to 82:

82+4.1=    $86.10 is the new amount.

Answer:

The diameter of the plate is 15 centimeters

Step-by-step explanation:

* Lets explain how to solve the problem

- All circles are similar

- In the similar circles the ratio between their circumferences is equal

 to the ratio between their diameters

* Lets solve the problem

∵ The circumference of a frying pan is 78.5 centimeters

∵ The circumference of a plate is 47.1 centimeters

∵ The frying pan and the plate are shaped circles

∴ The frying pan and the plate are similar

∴ C 1/C 2 = d 1/d 2 , where C 1 is the circumference of the frying pan ,

   C 2 is the circumference of the plate , d 1 is the diameter of the

   frying pan and d 2 is the diameter of the plate

∵ The diameter of the frying pan is 25 centimeters

∴ d 1 = 25

∵ C 1 = 78.5

∵ C 2 = 47.1

∵ C 1/C 2 = d 1/d 2

∴ 78.5/47.1 = 25/d 2

- By using cross multiplication

∴ 78.5(d 2) = (47.1)(25)

∴ 78.5(d 2) = 1177.5

- Divide both sides by 78.5

∴ d 2 = 15

∵ d 2 is the diameter of the plate

∴ The diameter of the plate is 15 centimeters

Answer:

c < 32

Step-by-step explanation:

1 / 4 c < 8

0.25 c < 8

8 / 0.25 = 32

c < 32

Answer:

[tex]c \:<\:32[/tex]

Step-by-step explanation:

The given inequality is

[tex]\frac{1}{4}c \:<\:8[/tex]

Multiply both sides of the inequality by the reciprocal of [tex]\frac{1}{4}[/tex] which is equal to 4.

This will give us;

There are a couple steps while finding the scale factor so stick with me. First, the main point is to find the similar figure. You need to find the corresponding side. Now, you write the ratio of the side you got. Begin with the small one, you will get a number below one. If you start with a greater number you will get a greater than the number one.

Answer:

Step-by-step explanation:

The vertex form of an equation of a parabola y = ax² + bx + c:

[tex]y=a(x-h)^2+k[/tex]

(h, k) - verex

[tex]h=\dfrac{-b}{2a},\ k=f(h)[/tex]

We have:

[tex]y=(x+5)(x+4)[/tex]            use FOIL (a + b)(c + d) = ac + ad + bc + bd

[tex]y=(x)(x)+(x)(4)+(5)(x)+(5)(4)=x^2+4x+5x+20=x^2+9x+20[/tex]

a = 1, b = 9, c = 20

[tex]h=\dfrac{-9}{2(1)}=\dfrac{-9}{2}=-\dfrac{9}{2}[/tex]

For k, put the value of h to the equation y = (x + 5)(x + 4):

[tex]k=\left(-\dfrac{9}{2}+5\right)\left(-\dfrac{9}{2}+4\right)\\\\k=\left(-\dfrac{9}{2}+\dfrac{10}{2}\right)\left(-\dfrac{9}{2}+\dfrac{8}{2}\right)\\\\k=\left(\dfrac{1}{2}\right)\left(-\dfrac{1}{2}\right)=-\dfrac{1}{4}[/tex]

Finally:

[tex]y=1\bigg(x-\left(-\dfrac{9}{2}\right)\bigg)^2-\dfrac{1}{4}\\\\y=\left(x+\dfrac{9}{2}\right)^2-\dfrac{1}{4}[/tex]

The quadratic function y = (x + 5)(x + 4) in vertex form is y = (x + 9/2)^2 - 41/4, and its vertex is at (-9/2, -41/4).

Expand the given expression:

y = x^2 + 4x + 5x + 20

y = x^2 + 9x + 20

Factor out the coefficient of x^2 from the x^2 and x terms:

y = 1(x^2 + 9x) + 20

To complete the square, take half of the coefficient of x (which is 9) and square it. Add and subtract this value inside the parentheses:

y = 1(x^2 + 9x + (9/2)^2 - (9/2)^2) + 20

Factor the perfect square trinomial inside the parentheses:

y = 1((x + 9/2)^2 - (9/2)^2) + 20

Simplify the expression:

y = (x + 9/2)^2 - 81/4 + 20

Combine the constants:

y = (x + 9/2)^2 - 41/4

So, the quadratic function y = (x + 5)(x + 4) in vertex form is y = (x + 9/2)^2 - 41/4, and the vertex of the parabola is (-9/2, -41/4).

First we must simplify the left side.

-20x² - 30x = 21

We need to move 21 to the left side of the problem, to do that we need to subtract both sides:

-20² - 30x - 21 = 0

Factor -1 out of -20x² - 30x - 21.

So then we have:

- (20x² + 30x + 21) = 0

Our set is: 20x² + 30x + 21 equal to 0 now we must solve for x.

To do that we need to divide.

x = -15 = √195

Hundreths go two decimals to the left from the point. 25.823 is rounded to 25.820 or 25.82

Answer:

-9.5

Step-by-step explanation:

To solve for z, use inverse operations by multiplying both sides by 2.

-4.75 = z/2

-9.5 = z

To solve the equation -4.75 = z/2, multiply both sides by 2 to isolate z, which gives you the solution z = -9.5.

To solve for z in the equation -4.75 = z/2, you need to isolate z on one side of the equation. This can be achieved by multiplying both sides of the equation by 2 (the reciprocal of 1/2, which is the current coefficient of z) to cancel out the division.

Here's the calculation step by step:

Therefore, the solution to the equation is z = -9.5.

The correct option is (D) x-7 + 2

let the quantity be x

Quantity minus 7 can be written as

x-7

Now

2 more means adding 2

So the final expression can be written as

(x-7) + 2

Answer:

The correct answer option is D. (x - 7) + 2.

Step-by-step explanation:

We are to determine whether which of the given options best describe the English expression:

'two more than the quantity of a number minus seven'

We can break this expression into smaller chunks to make it easier to translate.

1. two more than ---> +2

2. the quantity of a number ---> suppose the number to be 'x'

3. number minus 7 ---> (x - 7)

Combining these, we get (x - 7) + 2 so the correct answer option is D.

First, you need to find out the are of the whole rectangle, which as you probably know, you just need to multiply base by height.

Then, you need to substract the are of the two little squares, which luckily are both the same size. To find out the are of a square you multiply a side twice.

Therefore,

Whole rectangle area:

(32+8) * (8+8) = 40 * 16 = 640 sq. ft.

Two small squares:

2 * (8 * 8) = 2 * 64 = 128 sq. ft.

We substract:

640 - 128 = 512 sq. ft.

Answer:

512

Step-by-step explanation:

i fond the area of the whole big rectangle , so to do this i did 32+8 because i needed to find length. then i found the width, which was 8+8, 16. to find area , i need to multiply with times height so i did 40 x 16. this gets me to 640, but now i need to take out the two smaller cubes since i included them when i found the are of the rectangle. since the sides of both squares are 8 by 8, we can do 8 x 8 x 2 to find the area of both of them. now we taake 128(the product of 8 x 8 x 2) and subtract it from the big rectangle with the area of 640. 640-128 is 512.

Answer: Ramon

Step-by-step explanation:

because if you think about it ust of tooken 4 fo skyler to at least read 100 pages.

Ramon was faster.

A unit rate means a rate for one of something.

Given that, A hunter novel is 520 pages. Skyler has read 145 pages in 5 hours. Ramon has read 124 pages in 4 hours.

To find who is faster, we will find unit rate of each,

Skyler read 145 pages in 5 hours,

Therefore,

In 1 hour, he will read = 145 / 5 = 29

Therefore, in 1 hour he read 29 pages.

Ramon read 124 pages in 4 hours,

In 1 hour, he will read = 124 / 4 = 31

Therefore, in 1 hour he read 31 pages.

Since, Skyler read less pages than Ramon in one hour.

Hence, Ramon was faster.

Answer:200 club members

Step-by-step explanation:

Final answer:

To find the total club members when 164 members represent 82%, divide 164 by 0.82 to get 200 members in total.

Explanation:

To determine the total number of club members based on the percentage that prefers a dolphin mascot, we can set up a proportion. The problem tells us that 164 members represent 82% of the total number of club members. Using this information, we can set up the equation:

164 = 0.82 × Total club members

To find the total number of club members, we divide the number of members who want a dolphin by the percentage they represent as a decimal:

Total club members = 164 ÷ 0.82

By performing the division, we get:

Total club members = 200

Therefore, the total number of club members is 200.
