Ryan went to the store to buy some apples. The price per pound of the apples is $4.25
per pound and he has a coupon for $2 off the final amount. With the coupon, how
much would Ryan have to pay to buy 5 pounds of apples? Also, write an expression
for the cost to buy p pounds of apples, assuming at least one pound is purchased.

Answer:

No, I do not agree with them. Both are wrong.

Step-by-step explanation:

For a shape or figure to be considered a scaled copy of another, the length of all the segments of scaled copy must be equal to the length of all corresponding segments of the original figure multiplied by the same scale factor.

By examining the scaled copies B, C, and D, we would conclude that only D can be referred to as a scaled copy of D, because all the segments are exactly twice the corresponding segments of A. C and B do not have all its segment scaled in the same proportion.

Therefore, we cannot agree with Priya, nor Tyler. They are both wrong.

Using the numbers you have :

6 to -2

-2 to 2

4 to 1

-1 to 1

This is a function.

An input can only have one output, but an output can have multiple inputs.

We can make a table with the values we are given.

6 and -2

4 and -1

2 and 2

-2 and 1

Since no x-value repeats itself, it is a function. To make a function, no x-values can be repeated.

Best of Luck!

Answer:

The missing number is:

22

Step-by-step explanation:

There are 3 numbers and one more

4 numbers and your average is 17

then:

17*4 = 68

then:

11 + 17 + 18 + a = 68

46 + a = 68

a = 68 - 46

a = 22

Check:

(22 + 11 + 17 + 18)/4 = 17

68/4 = 17

Answer:

Thus, when both S-jams and C-tunes have 20 songs downloaded in a month  , the cost will be same.

an expression for the cost of S-Jams $0.99n + $16

Step-by-step explanation:

For

S-Jams

cost of 1 song = $1.29

let there be n songs downloaded in a month

then

cost of n songs = n*cost of 1 song  = $1.29n

monthly fee = $10

Total cost of S-Jams = $1.29n+$10

________________________________________

For

C-Tunes

cost of 1 song = $0.99

let there be n songs downloaded in a month

then

cost of n songs = n*cost of 1 song  = $0.99n

monthly fee = $16

Total cost for C-Tunes= $0.99n + $16

we have to find When will the company’s plans cost the same.

Total cost of S-Jams = Total cost of C- Tunes

1.29n+10 = 0.99n + 16

=> 1.29n - 0.99n = 16-10

=> 0.30n = 6

=> n = 6/0.3 = 20

Thus, when both S-jams and C-tunes have 20 songs downloaded in a month  , the cost will be same.

an expression for the cost of S-Jams $0.99n + $16

Answer:

Options A, C and D.

Step-by-step explanation:

It is given that, we need 1 tablespoon of butter for every 6 eggs to make a quiche.

Ratio that compares these two quantities [tex]=\dfrac{6\text{ eggs}}{1\text{ tablespoons} }[/tex]

We need to find the ratios which are equivalent to this ratio.

[tex]\dfrac{6\text{ eggs}}{1\text{ tablespoons} }\times \dfrac{2}{2}=\dfrac{12\text{ eggs}}{2\text{ tablespoons} }[/tex]

[tex]\dfrac{6\text{ eggs}}{1\text{ tablespoons} }\times \dfrac{3}{3}=\dfrac{18\text{ eggs}}{3\text{ tablespoons} }\neq \dfrac{15\text{ eggs}}{3\text{ tablespoons} }[/tex]

[tex]\dfrac{6\text{ eggs}}{1\text{ tablespoons} }\times \dfrac{4}{4}=\dfrac{24\text{ eggs}}{4\text{ tablespoons} }[/tex]

[tex]\dfrac{6\text{ eggs}}{1\text{ tablespoons} }\times \dfrac{1.5}{1.5}=\dfrac{9\text{ eggs}}{1.5\text{ tablespoons} }[/tex]

Therefore, the correct options are A, C and D.

Answer:

A,C,D

Answer:

Mark is 42. 3J = M and J + M = 56

Step-by-step explanation:

Since Mark is 3 times as old as Julie, and the sum of their ages is 56, you could divide 56 by 4 (one time because of Julie’s age, the other 3 times because of how many times Mark is older than Julie) You would get 14. That means that Julie is 14. To find Mark’s age, you would multiply 14 (Julie’s age) by 3. The answer would be 42.

Answer:

the EOQ cost function [tex]\mathbf{g(Q)= \dfrac{h}{2 \lambda Q}( Q- \sqrt{\dfrac{2 \lambda K }{2}})^2 + \sqrt{\dfrac{2 h K}{\lambda}}}[/tex]

Step-by-step explanation:

Given that:

[tex]g(Q) = \dfrac{h}{2 \lambda Q} \begin {pmatrix} Q- \sqrt{\dfrac{2 K \lambda}{h}} \end {pmatrix}^2 + \sqrt{\dfrac{2 Kh}{\lambda}}[/tex]

Total cost = Purchase Cost + Ordering Cost + Holding Cost

i.e

T = [tex]P \lambda + h \dfrac{Q}{2}+\dfrac{\lambda K}{Q}[/tex]

By differentiating with respect to Q and equating to zero, we have:

[tex]0 = 0 +\dfrac{h}{2}- \dfrac{\lambda K}{Q^2}[/tex]

[tex]Q* = \sqrt{\dfrac{2 k \lambda}{h}}[/tex]

Now;

[tex]T = P \lambda + \dfrac{h}{2Q}(Q-Q^*)^2 + hQ^*[/tex]

[tex]T = \dfrac{h}{2Q}(Q- \sqrt{\dfrac{2 \lambda K}{h}})^2 + \sqrt{2 hK \lambda } + P \lambda[/tex]

[tex](\dfrac{T - P \lambda}{\lambda }) = \dfrac{h}{2 \lambda Q}( Q- \sqrt{\dfrac{2 \lambda K }{2}})^2 + \sqrt{\dfrac{2 h K}{\lambda}}[/tex]

Therefore:

the EOQ cost function [tex]\mathbf{g(Q)= \dfrac{h}{2 \lambda Q}( Q- \sqrt{\dfrac{2 \lambda K }{2}})^2 + \sqrt{\dfrac{2 h K}{\lambda}}}[/tex]

Answer:

Property of Equality

Y= -13/7

Step-by-step explanation:

7y – 15 = –29.

Applying rule of equality which is"anything done on one side of the equal sign should be done also on the other side of the equal sign"

7y – 15 = –29.

Adding 15 to both sides

7y - 15+15= -28+15

7y= -13

Dividing throughout by 7

7y/7= -13/7

Y= -13/7

[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{x = 4}}}}}[/tex]

Step-by-step explanation:

[tex] \sf{2x + 4 = 12}[/tex]

Move 4 to right hand side and change it's sign

[tex] \dashrightarrow{ \sf{2x = 12 - 4}}[/tex]

Subtract 4 from 12

[tex] \dashrightarrow{ \sf{2x = 8}}[/tex]

Divide both sides by 2

[tex] \dashrightarrow{ \sf{ \frac{2x}{2} = \frac{8}{2} }}[/tex]

Calculate

[tex] \dashrightarrow{\sf{x = 4}}[/tex]

Hope I helped!

Best regards! :D

Answer:

[tex]x=4[/tex]

Step-by-step explanation:

[tex]2x+4=12[/tex]

To solve this equation, first we must minus out(subtract) 4 from both sides of the equation.

[tex]2x+4-4=12-4[/tex]

This equals [tex]2x=8[/tex]

Now we will make this into a fraction and divide the sides by 2.

[tex]\frac{2x}{2}[/tex] equals to [tex]\frac{8}{2}[/tex]

Now we got an answer!

[tex]x=4[/tex]

Answer:

X=7

Step-by-step explanation:

4(x+3) - 10=6 ( x-2)

multiply

4x +12 - 10 = 6x - 12

4x + 2 = 6x- 12

subtract the positive 2 to the -12

4x = 6x -14

subtract 6x to the 4x

-2x = -14

divide -2 from the -14 (neg divided by a neg = positive)

x= 7

Answer:

$38.64

Step-by-step explanation:

so the equation needed to solve is $56*0.25 and that number is 14. Since it is a coupon you subtract 14 from 56 and end up with 42. Now multiply 0.08*42 and you got your sales tax, $3.36. now subtract that from 42 and you have your answer

Answer:

He paid 50 dollars

Step-by-step explanation:

25% off = 75/100 x 56 = 42

42 + 8 = 50

if this question is about what percentage the tax is, then the answer would be 19.05%

x/100 x 42 = 50

42x/100 = 50

42x = 5000

x = 5000/42

x = 119.05

119.05 - 100 = 19.05%

Answer:

Not always but sometimes

Step-by-step explanation:

The product of two irrational numbers is sometimes and not always an irrational number.

So, Let us take two Example:

Example # 1:

Let the two irrational numbers be [tex]\sf \sqrt{37} \ and \ \sqrt{2}[/tex]

So, Multiplying these will give us

=> [tex]\sf \sqrt{37} * \sqrt{2}[/tex]

=> [tex]\sf \sqrt{74}[/tex]

Which is an irrational number.

Example # 2:

Let the two irrational numbers be [tex]\sf \sqrt{2} \ and \ \sqrt{2}[/tex]

So, Multiplying them would give us:

=> [tex]\sf \sqrt{2} * \sqrt{2}[/tex]

=> [tex]\sf (\sqrt{2} )^2[/tex]

=> 2

Which is a rational number.

This means that the product of two irrational numbers is not always an irrational number but sometimes an irrational number.

Answer:

– 2

Step-by-step explanation:

From the question given above, the following data were obtained:

P(x) = polynomial

P(–5) = – 2

P(5) = –1

Remainder when P(x) is divided by

(x + 5) =?

To obtain the remainder when P(x) is divided by (x + 5), we shall apply the reminder theorem as follow:

Let (x + 5) be equal to 0

(x + 5) = 0

x + 5 = 0

Subtract 5 from both side

x + 5 – 5 = 0 – 5

x = –5

Replace x in P(x) with –5 as shown below:

P(x) = polynomial

x = – 5

P(–5)

From the question given above,

P(–5) = – 2

Therefore, when P(x) is divided by

(x + 5), the remainder is – 2.
