Answer:

B

Step-by-step explanation:

The picture represents a compass and a straightedge construction of bisecting a line segment.

- Bisect a line segment

Option C is the correct answer.

A segment bisector is a line, a ray, a line segment, or a point that cuts a line segment at the center dividing the line into two equal parts.

We have a figure,

There are two line segments.

One line segment is bisected by the compass at point B.

One line segment is bisected by the compass at point F.

Thus the picture represents a compass and a straightedge construction of bisecting a line segment.

Answer:

1. 252N = ([tex]2^{2}[/tex] x [tex]3^{2}[/tex] x [tex]7^{1}[/tex])N

2. Factor = [tex]2^{5}[/tex]

Step-by-step explanation:

Let the starting population size for organisms A and B be represented by N.

For organism A;

Day 0: N

Day 1: 2N

Day 2: [tex]2^{2}[/tex]N

Day 3: [tex]2^{3}[/tex]N

Day 4: [tex]2^{4}[/tex]N

Day 5: [tex]2^{5}[/tex]N

Day 6: [tex]2^{4}[/tex]N

Day 7: [tex]2^{3}[/tex]N

Day 8: [tex]2^{2}[/tex]N

For organism B;

Day 0: N

Day 1: 2N

Day 2: [tex]2^{2}[/tex]N

Day 3: [tex]2^{3}[/tex]N

Day 4: [tex]2^{4}[/tex]N

Day 5: [tex]2^{5}[/tex]N

Day 6: [tex]2^{6}[/tex]N

Day 7: [tex]2^{7}[/tex]N

Day 8: [tex]2^{8}[/tex]N

1. After the eight days, organism B's population is larger than organism A's population by;

[tex]2^{8}[/tex]N - [tex]2^{2}[/tex]N = 256N - 4N

               = 252N

Pls make me brainliest much appreciated

The transformation that maps the pre-image to the image i.e. ABCD to A'B'C'D'  is the Dilation transformation.

Changing in size without changing the shape of the given figure, such transformation is known as dilation.

We have,

According to the question:

Smaller Rectangle ABCD has side lengths 5, 4, 5, 4.

And,

Rectangle A'B'C'D' has side lengths 10, 8, 10, 8.

So,

The size of rectangle A'B'C'D' get increases as compared to rectangle  ABCD.

Hence, We can say that the transformation dilation would transform the ABCD into the A'B'C'D' by dilation.

495 miles

Step-by-step explanation:

If the light rail goes 165 miles per hour (mph) and if it was to travel for 3 hours you would multiply 165 mph x 3 = 495

Hey there!

[tex]Answer: \boxed{495\text{ miles}}[/tex]

[tex]Explanation:[/tex]

The light rail traveled 165 miles in one hour. The question is asking how many miles would it travel in 3 hours. So the only thing you have to do is multiply 165 miles by 3 hours.

[tex]165*3=495\\[/tex]

So it traveled 495 in 3 hours. So the answer to your question is:

Answer:

Step-by-step explanation:

Each triangle has a formula of 1/2 a*b

So one triangle = 1/2 * 12 * 15 = 90

So the other one is the same area of 90 square feet.

Together they make 180 square feet.

You can check this by simply multiplying  a*b = 12 * 15 = 180 square feet.

[tex]x<-\frac{7}{10}[/tex]

Step-by-step explanation:

[tex]10x - 5 <41 - 53[/tex]

[tex]10x-5<-12[/tex]

Add 5 to both sides:

[tex]10x-5+5<-12+5[/tex]

[tex]10x<-7[/tex]

Divide both sides by 10:

[tex]\frac{10x}{10}<\frac{-7}{10}[/tex]

[tex]x<-\frac{7}{10}[/tex]

Answer:

x= 5.5

Step-by-step explanation:

18=12x-48

-12x= -48-18

-12x= -66

x= -66/-12

x= 5.5

Answer:

Okay so first you distribute 6 into the parenthesis that gives you

18=12x-48

Then you add 48 on both sides

66=12x

then you divide

X=5.5

Step-by-step explanation:

Answer:

If M is midpoint of AB, then

AM=MB

4x-5= 2x+11

2x=16

x=8

AM= 4x-5

=4(8)-5

=32-5

=27

BM=2x+11

=2(8)+11

=16+11

=27

Answer:

x = 30

y = 10

Step-by-step explanation:

3x° is a right angle so it equals 90°. To solve for x, you need to divide 90 by 3. This equals 30.

In order to find what the angle with y equals, you have to find the rest of them. So if you add 135° + 90° + 90° you get 215. Which is the missing angle.

So to solve for y in (5y - 5) = 45°, you add 5 to 45, which is 50 and then divide by 5. This is how you get y=10.

=============================================

U = set of natural numbers less than 8

U = {1,2,3,4,5,6,7,8}

G = set of even integers less than 10

G = {..., -4, -2, 0, 2, 4, 6, 8}

Circle the items in G that are also in set U. Those items are {2,4,6,8}

Then go back to set U = {1,2,3,4,5,6,7,8} and erase 2,4,6,8 to be left with {1,3,5,7}

The complement of a set is everything that isn't in a given set. Think of it as the opposite.

Answer:

y=-4

Step-by-step explanation:

Equation: -1/3(y-3)=11

First multiply -1/3 by y and by -3 because they are in parenthesis:

-1/3*y=-1/3y

-1/3*3=1

-1/3y-1=11

Next add 1 on both sides:

-1/3y-1+1=11+1

-1/3y=12

Now divide -1/3 on both sides:

-1/3y÷-1/3=12÷-1/3

y=-4
