Answer:

A and C.

Step-by-step explanation:

Remember that to find the scale factor, we can write a ratio between each of the corresponding sides.

In other words, the scale factor k will be:

[tex]k=\frac{\text{Enlarged Side}}{\text{Corresponding Original Side}}[/tex]

Most importantly, their sides must be corresponding.

So, let's go through each of the answer choices.

A)

We have:

[tex]k=\frac{\text{Enlarged}}{\text{Original}}=\frac{6.5}{3.25}[/tex]

In our figures, we can see that 6.5 from our scaled figure indeed corresponds to 3.25 from our original figure. So, A is correct.

B)

We have:

[tex]k=\frac{\text{Enlarged}}{\text{Original}}=\frac{3.25}{6.5}[/tex]

This is not correct because 3.25 is our original, not our enlarged. It should be flipped, like choice A. So, B is not correct.

C)

We have:

[tex]k=\frac{\text{Enlarged}}{\text{Original}}=\frac{3}{1.5}[/tex]

We can see that 3 from our enlarged figure indeed corresponds with 1.5 from our original figure. So, choice C is also correct.

D)

We have:

[tex]k=\frac{\text{Enlarged}}{\text{Original}}=\frac{1.5}{3}[/tex]

Similarly to B, this is not correct because our enlarged number should be in the numerator while our original number should be in the denominator. So, D is not correct.

E)

We have:

[tex]k=\frac{\text{Enlarged}}{\text{Original}}=\frac{1.5}{3.25}[/tex]

This is not correct because the sides do not represent the scaled figure. Both of the given side lengths are from the original figure, and so we cannot determine the scale factor from this.

So, our final answers are A and C.

And we're done!

Answer:

A and C

Step-by-step explanation:

The solution is Option A

The ratio of length : width : thickness of the plank is 1 : 12 : 4

The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.

The proportional equation is given as y ∝ x

And , y = kx where k is the proportionality constant

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Given data ,

Let the proportion be represented as A

Now , the length of the plank = 1 cm

The width of the plank = 12 cm

The thickness of the plank = 4 cm

Now , the proportion is given as

The ratio of length : width : thickness of the plank = 1 : 12 : 4

Therefore , the value of A is 1 : 12 : 4

Hence , the proportion is  1 : 12 : 4

Answer:

D) x=  -24

Step-by-step explanation:

Answer: -8

So, an integer is 12 units away from 4. This could either be positive or negative. If it was positive, it would be 16. If it was negative, it would be -8. Though at this point we don’t know. Then the question goes on saying that it’s 4 units away from -4. This could be positive, 0, or negative, -8. Before, we got a similar answer of -8. So, I conclude that the answer is -8.

Answer:

Step-by-step explanation:

-14 + 2x + 3 = 4x - 13 - 7x

We can first add the numbers and coefficients on either side:

2x - 11 = -3x - 13

Then, we can add 3x to both sides:

5x - 11 = -13

We can add 11 to both sides

5x = -13 + 11 = -2

Lastly, we can divide both sides by 5

x = -2 / 5

Answer:

The angles are 60,60 ,120,120

Step-by-step explanation:

The sum of the angles of a quadrilateral is 360 degrees

x+x+1/2x + 1/2x = 360

Combine like terms

3x = 360

Divide each side by 3

3x/3 = 360/3

x = 120

1/2x = 1/2 (120) = 60

x= 120

The angles are 60,60 ,120,120

Answer:

x = 2.17 (rounded to the nearest hundredth)

Step-by-step explanation:

10x - 3x + 5x = 26

Subtract 3x from 10x

7x + 5x = 26

Add 7x and 5x together

12x = 26

Divide 26 by 12

x = 2.17 (rounded to the nearest  hundredth)

Hello! :)

To find you equation, we will first simplify both sides of the equation

10x - 3x + 5 = 26

10x + -3x + 5 = 26

(10x -3x) + (5) = 26

7x + 5 = 26

7x +5 = 26

Now, we will subtract 5 from both sides

7x + 5 - 5 = 26 - 5

7x = 21

At last, we will divide both sides by 7

7x/7 = 21/7

Answer:

3/4 cup of coconut oil

Step-by-step explanation: 2/3 cup of toothpaste equals 1/2 a cup of coconut oil. If you split 2/3 in half you get 1/3. And if you split 1/2 in half you get 1/4. Since there are 3 thirds in a cup you will have 3/4 cups of coconut oil because for every 1/3 cup there is 1/4 cup of coconut oil.

1/3+ 1/3+ 1/3= 3/3 or 1

1/4+ 1/4+ 1/4= 3/4

The amount of coconut required per cup of toothpaste is 0.75 cups.

Amount of coconut oil = 1/2 cup

Amount of tooth paste = 2/3 cup

This can be related thus :

Hence, to make 1 cup of tooth paste, let amount of coconut oil required = x

1/2 = 2/3

x = 1

Cross multiply

2/3x = 1/2

0.66666x = 0.5

x = 0.5 / 0.666666

x = 0.75

Therefore, 0.75 cup of coconut oil is required per cup of toothpaste.
