A store sells a package of 12 trading cards for ​$5.52. Use pencil and paper. Explain how you can tell that the unit price per c
GrogVix [38]

Answer:

The cost of 12 trading cards are less than $12 so we can say that unit price of the card is lesser than $1.

Unit price per card is $0.46.

Step-by-step explanation:

Given:

Cost of 1 package of trading card = $5.52

Number of trading card in a package = 12

We need to explain how can we tell that the unit price per card is less than​ $1.

Also We need to unit price per card.

Solution:

Now we can see that;

Cost of 1 package of trading cards is $5.52

And we know that;

1 package contains 12 trading cards.

It means that;

Cost of 12 trading cards is $5.52.

From above we can say that;

If the cost of 12 trading cards were $12 or more than $12 than we would say that unit price of the card is $1 or greater than $1 respectively.

But the cost of 12 trading cards are less than $12 so we can say that unit price of the card is lesser than $1.

Now we will find the unite price per car.

12 trading cards =$5.52

1 trading card = Cost of 1 trading card.

Using Unitary method we get;

Cost of 1 trading card = \frac{5.52}{12} = \$0.46

Hence Unit price per card is $0.46.

HELP PLEASEEEE I WILL AWARD 100 POINTS ITS DUE ASAPPP<br> What is the equation for A(w)=?
skad [1K]

Answer:

390=W 195=L Area=76050

Step-by-step explanation:

You have two lengths and one width for your perimeter

P= 2L + W

you are given your perimiter 780

780= 2L + W

To solve for your maximum Width

780-2L=w

Area is L * W

A= (780-2L)*L

A= 780L - 2L^2

the derivitive of the Area

A' = 780-4L =0

add 4L to both sides

780=4L

divide by 4 on both sides

195=L

Bring back 780-2L=W and plug in what you now know is L

780-2(195)=W

780-390=W

390=W

The area of rectangle ABCD is 28 cm^2
Sonbull [250]

The length of AB is (x + 4) cm and the values of a and be are a = 10, b = 4

A rectangle is a quadrilateral in which opposite sides are equal and parallel to each other. The area of a rectangle is:

Area = length * width

From the image:

Length of AB = x + 4

Length of BC = x + 6

The area of rectangle ABCD = Length of AB * Length of BC

28 = (x + 4)(x + 6)

x² + 10x + 24 = 28

x² + 10x = 4

Comparing with x² + ax = b gives:

a = 10, b = 4

Therefore the length of AB is (x + 4) cm and the values of a and be are a = 10, b = 4
