Answer:

1/3

Step-by-step explanation:

Look at two corresponding lengths that are easy to measure.

BC and B'C' are both along horizontal lines, so you can easily count squares to find their lengths.

BC = 3

B'C' = 1

B'C' is the image, and BC is the original.

The scale factor is obtained by dividing a length of the image by the corresponding length of the original.

scale factor = B'C'/BC = 1/3

Answer: 1/3

Talja [164]

Answer:

Step-by-step explanation:

we have 105 marbles

number of blue marbles= x

green marbles= x+25

x+x+25=105

2x=105-25

2x=80

x=40 blue marbles

Which equation represents a line that intersects the line 2y − 4x = 3? A.-2y + 4x = 1 B. 3y − 6x = 6.5 C. y − 2x = 3 D. -2y − 4x

irga5000 [103]

Convert all the equations to slope-intercept form:
$2y-4x=3 \ \ \ |+4x \\
2y=4x+3 \ \ \ |\div 2 \\
y=2x+\frac{3}{2}$

$A. \\
-2y+4x=1 \ \ \ |-4x \\
-2y=-4x+1 \ \ \ |\div (-2) \\
y=2x-\frac{1}{2} \\ \\
B. \\
3y-6x=6.5 \ \ \ |+6x \\
3y=6x+6.5 \ \ \ |\div 3 \\
y=2x+\frac{13}{6}$

$C. \\
y-2x=3 \ \ \ |+2x \\
y=2x+3 \\ \\
D. \\ 
-2y-4x=3 \ \ \ |+4x \\
-2y=4x+3 \ \ \ |\div (-2) \\
y=-2x-\frac{3}{2}$

Lines A, B and C have the same slope as the line 2y-4x=3, so they are parallel and don't intersect it.
Line D has another slope, so it intersects the line 2y-4x=3.
The answer is D.

Identify the parts relating to o A.<br> What is FG?<br> What is DB?<br> What is DH?<br> What is AC?

svetoff [14.1K]

Answer:

Usually, when a question says "FG" or "DB" or any of the other letters put together, they mean the line that it connects to. For example: Point A to Point C. However, I can't say so for sure, because This answer most likely has a diagram drawn beside it. If you can put the diagram or picture along with your questions, I can help you out more!
