The pairs of polygons are similar. Give the scale factor of Figure A to figure B

Answers

Answer:

2/5

Step-by-step explanation:

Use two corresponding sides.

In triangle A, look at the side between 1 mark and 2 marks on the angles. Its length is 10.

In triangle B, look at the side between 1 mark and 2 marks on the angles. Its length is 4.

To find the scale factor from A to B, divide a length in B by its corresponding length is A.

4/10 = 2/5

Answer: The scale factor from A to B is 2/5.

Given that Figure A and Figure B are similar polygons, the scale factor of Figure A to Figure B = 5/2.

Recall:

Similar Polygons have corresponding side lengths whose ratio are equal. That is, their pairs of corresponding sides are proportional.The ratio of any of their corresponding side length = scale factor

Given the two pairs of similar polygons, the scale factor of figure A to figure B will be calculated as follows:

A side length of Figure A = 10Corresponding side length of Figure B = 4

Scale factor of Figure A to Figure B = 10/4 = 5/2

Daniel is on vacation. He goes to a shopping mall to buy some keychains for his friends as souvenirs. At the shopping mall, he
spent $3.87 on a sandwich. If each keychain costs $2.28 and he has $20.00 with him, what is the maximum number of keychains he
can buy?
A. 9
B.
10
C. 7
8

Answers

Answer:

7

Step-by-step explanation:

20.00 - 3.87 = 16.13

2.28 x 7 = 15.96

Number of key chain he can buy is 7 keychain

Given that;

Amount spend in shopping mall = $3.87

Cost of each key chain = $2.28

Amount he has = $20

Find:

Number of key chain he can buy

Computation:

Assume;

Number of key chain he can buy = a

So,

2.28a + 3.87 = 20

2.28a = 16.13

a = 16.13 / 2.28

a = 7.074

Number of key chain he can buy = 7

Equation is y=1.5x+4 find an answer for:

Write an equation in standard form whose line is less steep and translated down 7 units.

Answers

Answer:

  6x -5y = 15

Step-by-step explanation:

The given line has a slope of 1.5 and a y-intercept of 4. We assume that "translated down 7 units" means the y-intercept needs to be -3. "Less steep" will mean the slope is less than 1.5. We can make the slope be 1.2, so it will be less steep.

Then the slope-intercept form of the desired line is ...

  y = 1.2x -3

Adding 3-y, this becomes ...

  1.2x -y = 3

Multiplying this by 5 to put it into standard form, we have ...

  6x -5y = 15

_____

Additional comment

Since the lines have different slopes, each point on the original line will be translated up or down by a different amount. We chose the y-intercept as the point to be translated by the specified amount. The question could be more clear on that point, as well as whether lines with negative slope (say, -2) are considered to be "less steep."

What is 18 9/11 - 8 3/8

I need help asap

Answers

Answer:

10.44318182 or 919/88 or 10 39/88

Step-by-step explanation:

I used my calculator :)

Answer:

Step-by-step explanation:

18 9/11 - 8 3/8

First, we need to convert these fractions to improper fraction,

(18 * 11 + 9 / 11) - (8 * 8 + 3 / 8)

=> 207 / 11 - 67 / 8

Next, we need to find the LCM, the LCM of 8 and 11 = 88 (This is because 8 and 11 share no common factors other than 1, so the LCM will be the product of the 2 numbers)

=> (207 * 8) / (11 * 8) - (67 * 11) / (8 * 11)

=> 1656 / 88 - 737 / 88

So, then we just need to subtract the numerators to get the answer,

=> (1656 - 737) / 88

=> 919 / 88

Now, let us return it to the mixed fraction form,

=> 10 39/88

Write 4-6 sentences describing how you can use the form of a quadratic equation to decide how it can most efficiently be solved. For each solution method (factoring, by inspection, taking a square root, completing the square, and the quadratic formula), formulate an equation that would be the most efficiently solved using that approach. Write a comprehensive solution process for each as though you are explaining it to a friend who is struggling with this topic.

I do not need 4-6 sentences, but just need main points so I can form my own sentences.

Answers

Answer:

See explanation

Step-by-step explanation:

The place to begin in attempting to solve a quadratic equation is to try to factorize it. If it can not be factorized, then look at the side of equation that contains the variable (x,b,m,n and so on). If that side is a perfect square, try to take square root of both sides.

Also, if the coefficient of the squared term in the equation is 1 and the coefficient of the middle term bearing the variable is an even number, then you can attempt to use completing the square method. Formula method can be adopted as a last resort.

x^2 -4x + 4 =0 can be solved by factorization

X(x-2) - 2(x-2) =0

Hence;

(x-2) (x-2) =0

x= 2 (twice)

(2x-2)^2 = 4 can be solved by taking square root

√[(2x-2)^2] = √4

2x-2 = 2

x= ±2

x^2 + 6x - 11 = 0 can be solved by completing the square

(x + 3)^2 = 11 + 3^2

(x + 3)^2 = 20 taking square root of both sides

x + 3 = ±√20

x + 3 = ±2√5

x= -3 ±2√5

2x^2 - x + 5 = 0 can be solved by formula method

Using

x= -b±√b^2 - 4ac/2a

a= 2, b = -1, c= 5

x= 1 ± √1 - 40/4

x= 1 ± √-39/4

x= 1 ± 39i/4
