algebraic expression for the final price of a book that costs d dollars.

Answers

Answer 1

Answer: .75d = x

Step-by-step explanation:

D is the price. 25% off = - .25

1 - .25 = .75

x (final price) = d * .75

.75d = x

Answer: p=2

Step-by-step explanation:

4.05p+14.40=4.50p+13.50

4.50p-4.50p=13.50-14.40

-0.45p=-0.90

When this 3-digit number is rounded to the nearest hundred it rounds down to 600. The digit in the ones place is the third odd number that you count beginning with 1. The sum of the digits is 13. What is the number?​

Answers

Answer:

1. rounds down to 600 = 601 - 649

2. The digit in the ones place is the third odd number that you count beginning with 1. = 605

3. The sum of the digits is 13

Answer:

625

Step-by-step explanation:

Firstly, I found the ones place because I just needed to know the third odd number starting from 1. The first odd number is 1 then 3 and then 5, so I know that the digit in the ones place is 5.

Ones place: 3rd odd number: 1, 3, 5

Then, I looked at the hundreds place, because I know that it is rounded to down to 600 in the nearest hundred, I know it has to be 649 or smaller and bigger than 600. In the range of 600-649, the hundreds place remains the same, and therefore I know that the digit in the hundreds place is 6

Finally, to determine the tens place, I can do 13-(6+5) I can do this because I know that the sum of the digits is 13. Because 13-11=2, I know that the digit in the tens place is 2

Final number: 625

Part A:
Jason buys a pair of pants for $28.97, a top for $12.82 and a scarf for $9.18. He has a gift card worth $75. If the sales tax on the purchase is $3.19, what is the total of his purchase?

Part B:
Will he have enough money left to buy a hat for $27.15?
Explain your answer.

Answers

Answer:

Explanation:

Part A:

Total purchase = 28.97 + 12.82 + 9.18 + 3.19 = 54.16$

Part B:

75$ - (54.16 + 27.15) = 75 - 81.31 = -6.31

Therefore, he won’t have enough money to buy the hat.
Part a: When you add them all together you will get $54.16

Part b: no he won’t.

Here is trapezoid A in the coordinate plane:

If you drew Trapezoid B, the image of A after a 90\circ∘ rotation clockwise, using the origin as the center of rotation, what would be the coordinates of each of the vertices?

Answers

Answer:

(1,-2) (3,-2) (4,-4) (1,-4)

Step-by-step explanation:

First of all I noted that the origin would be the centre of rotation.

Then I chose a point of Trapezoid A: I selected the point closest to the centre of rotation which was (2,1) , since that is the easiest one to do. However, this works for any point

Then I drew a line from the point (2,1) to the centre of rotation (the origin)

From the origin I then drew another line perpendicular (at a right angle to) the line that I previously drew (between the origin and point (2,1)). I drew this line so that it was also the same length as the previously drawn line and I drew it in the direction of rotation which was clockwise i.e., to the right. This line therefore went from the origin to point (1,-2).

I have now deduced that the point (1,-2) is the same as point (2,1) but in the rotated Trapezoid B.

From there I simply just rotated shape A 90 degrees clockwise so that I knew what the shape would look like if it was rotated.

Then I just drew in the other points to make the rest of the shape.

Sorry if this is hard to understand. I would be able to explain better if I was able to draw this out for you

Given that,
To determine the coordinate of the given trapezoid after the 90° clockwise rotation with origin as the center of rotation.

What is the graph?

The graph is a demonstration of curves which gives the relationship between the x and y-axis.

Here,
Intial coordinates of the trapezoid, (1,2) , (3, 2), (4, 4) and (4, 1)
After the rotation of 90° clockwise, the trapezoid is translated to the 4 quadrants and the new coordinates are (1, -2) (3, -2) (4, -4) (1, -4).

Thus, the final coordinates are, (1, -2) (3, -2) (4, -4) (1, -4).

Answers

Answer:

409

Step-by-step explanation:

This is very easy. First of all you need to workout out 1/10 of the value of the 9 in 296. The value of the 9 in 296 is 90.

1/10 of 90 is 9 (since 1/10 x 90 = 90/10 = 9)

The only number which has 9 as its final digit is 409

409 because if multiply 9 and 296

1.How can you use an equation to make a prediction from a pattern?

2.Give an example of an open equation.

Answers

1) Using equations, you will are able to predict data from a specific value of independent variable. You can see how does the independent variable affect the dependent variable.

2) If x = 1 then 2 + 1 = 5 is false. If x = 3 then 2 + 3 = 5 is true. Thus, we can say that the mathematical sentence containing the variable becomes either true or false depending upon the value of the variable. This type of sentence is called an open sentence, thus 2 + x = 5 is an open sentence.

Area = 12 • 15

Area = 180

Area = length • width

Take the area of the none shaded part

Area = 8 • 2

Area = 16

Now subtract 16 from 180

180 - 16 = 164

2/9 +5/12 -7/18

Answers

the answer will be 1/4

Answer:

1/4

Step-by-step explanation:

Step 1 : Find a common denominator. We will use 36 as the denominator since 9, 12, and 18 are all factors of 36.

Step 2 : The number you multiple the denominator by must be the same number you multiply its numerator by.

Example : 2/9    To get a denominator of 36 you need to multiply 9 by 4. Now you need to multiply 2 by 4 as well.

Step 3 : Convert fractions into the new fractions

2/9 (times 4 on both sides) = 8/36

5/12 (times 3 on both sides) = 15/36

7/18 (times 2 on both sides) = 14/36

Step 4 : Plug new numbers into the equation.

8/16 + 15/36 - 14/36

Step 5 : Solve

8/16 + 15/36 = 23/36

23/36 - 14/36 = 9/36

Step 6 : Simplify

9/36 (divide by 9 on both sides) = 1/4
