Triangle DEF Is Dilated To Create Triangle DAB. What Scale Factor Was Used?please Hurry In Less Than

Answers

Answer 1

Answer:

Not sure how you would word it but the bigger triangle is 2 times larger than DEF.

Step-by-step explanation:

DE=4

AE=4

4+4=8

AD=8

Hope this helps!!

Answer 2

The scale factor used to create DAB from triangle DEF is 2.

What are transformations?

Two-dimensional figures can be transformed mathematically in order to travel about a plane or coordinate system.

Dilation: The preimage is scaled up or down to create the image.

Reflection: The picture is a preimage that has been reversed.

Rotation: Around a given point, the preimage is rotated to create the final image.

Translation: The image is translated and moved a fixed amount from the preimage.

The length of the base of the triangle DEF is 4 units and of DAB is 8 units.

The length of the height of DEF is 3 units and that of DAB is 6 units.

From this, we conclude that the scale factor is 2 as 8 is a multiple of 2×4 and 6 is a multiple of 2×3.

Which expression is equivalent to 2^5(4×+9)

Answers

Answer:

128x + 288

Step-by-step explanation:

Given the expression 2^5(4×+9)

on factoring

2^5(4×+9) = 2^5(4x) + 2^5(9)

2^5(4×+9) = 32(4x) + 32(9)

2^5(4×+9) = 128x + 288

Hence the expression is also equivalent to 128x + 288

Simplifying the expression [tex](3\:.\:2)^5\div (3^2\:.\:2^3)[/tex] so, there is only one power of each base we get [tex]\mathbf{3^3\:.\:2^2}[/tex]

Option D is correct answer.

Step-by-step explanation:

We need to simply the expression [tex](3\:.\:2)^5\div (3^2\:.\:2^3)[/tex] so, there is only one power of each base.

Solving:

[tex](3\:.\:2)^5\div (3^2\:.\:2^3)[/tex]

We can write it as:

[tex]\frac{(3\:.\:2)^5}{3^2.2^3}[/tex]

Now using exponent rule: [tex](a\:.\:b)^m=a^m\:.\:b^n[/tex]

[tex]\frac{3^5\:.\:2^5}{3^2.2^3}[/tex]

Now using the exponent rule: [tex]\frac{a^m}{a^n}=a^{m-n}[/tex] the bases should be same

[tex]3^{5-2}\:.\:2^{5-3}\\=3^3\:.\:2^2[/tex]

So, simplifying the expression [tex](3\:.\:2)^5\div (3^2\:.\:2^3)[/tex] so, there is only one power of each base we get [tex]\mathbf{3^3\:.\:2^2}[/tex]

Option D is correct answer.

A hot air ballon went from an elevation of 6,669 feet to an elevation of 3,402 in 54 minutes. What was its rate of descent?

Answers

Answer:

elevation refers to the height of the balloon. Descent refers to moving down, and rate of descent refers to how quickly the balloon moved down.

  In this case, we have a descent of 2,125 feet (initial height of 5,439 - ending height of 3,314). Since it took 34 minutes for the balloon to descend this distance, we divide the descent by the time (2,125/34). This gives us a rate of 62.5 feet per minute.

  That means that the balloon traveled downward 62.5 feet every minute. That's a fast moving balloon!

Blank 1: 28

Blank 2: 42

Blank 3: 22

Answer: It will take 7 sessions.

Step-by-step explanation:

We already know the 3 blanks from the equation 28x = 42 + 22x

Now to find the answer.

28x = 42 + 22x

Subtract 22x from both sides. This cancels the +22x.

28x - 22x = 42

Subtract 22x from 28x to get 6x

6x = 42

Divide both sides by 6. This undoes the multiplication by 6.

x = 42/6

Divide 42 by 6 to get 7.

x = 7

It will take 7 sessions for the costs to match.

Divide both sides by 4, and you get:

x = 3.

4x-2=10
• 4x-2+2=10+2

which is 1/3 - 1/6 in a fraction

Answers

Answer:

Step-by-step explanation:

1/3 - 1/6

2/6 -1/6= 1/6

find common denominator

For  [tex]\dfrac{1}{3}-\dfrac{1}{6}[/tex]  the fraction will be [tex]\dfrac{1}{6}[/tex] .

Given to us,

[tex]\dfrac{1}{3}-\dfrac{1}{6}[/tex]

To solve this, firstly we need to make the denominators the same, thus taking the LCM of both 3 and 6.

As we know the LCM of 3 and 6 is 6 itself.

So, multiplying and dividing by 2.

[tex]\dfrac{1}{3}\rightarrow \dfrac{1\times 2}{3\times 2}\rightarrow \dfrac{2}{6}[/tex]

Now,

[tex]\dfrac{2}{6}-\dfrac{1}{6} = \dfrac{1}{6}[/tex]

Hence, for  [tex]\dfrac{1}{3}-\dfrac{1}{6}[/tex]  the fraction will be [tex]\dfrac{1}{6}[/tex] .
