Answer:
A.) Extending the line of multiple of scale factor r on two corresponding vertex
B.) Scale factor r = 2.5
C.) A'B'/AB = 5/2
Step-by-step explanation:
A.) To find the centre O, take a corresponding vertex of the two shapes. Draw a line passing through the the vertex and extending beyond the initial one. The length of the line must be multiplied by the scale factor r
The center of a dilation is a fixed point in the plane in which all points are expanded or contracted.
B.) If AB=6 mm and A'B'= 15mm,
The scale factor r = 15/6 = 5/2 = 2.5
C.) A'B'/AB = 5/2
what is 10 1/3 x 1/4? that is, what is ten and one third times one fourth?
Answer: 31/12, or 2 7/12
Step-by-step explanation: The answer is actually very simple. All you have to do is to simplify 10 1/3 into 31/3, as 10x3+1=31. Then, you have to multiply 31/3 with 1/4. Do a simple fraction multiplication, and you get 31/12, or 2 7/12 if your teacher is asking for a mixed number. Sometimes simplifying is better

A proportional relationship is shown in the table below: x 0 3 6 9 12 y 0 0.5 1.0 1.5 2.0 What is the slope of the line that represents this relationship? \qquad Graph the line that represents this relationship.
Answer:
Take two point from the table, doesn't matter which ones, because this is linear. I will choose (0,0) and (3,.5).
Now follow the equation for slope: m = change in y / change in x.
[tex]\frac{y2-y1}{x2-x1}[/tex]
[tex]\frac{.5-0}{3-0}[/tex]
[tex]\frac{.5}{3}[/tex]
[tex]\frac{1}{6}[/tex]
The slope is 1/6. m=1/6
Its y-intercept is at 0. b=0
So the equation is y = 1/6x. The graph is attached.

Step-by-step explanation:
Two parallel lines will have the same slope. The slopes of parallel lines have to be equal. The y-intercepts of those two lines have to be different, otherwise they would be the same line. The x-intercepts of the parallel lines would also be different.

What is the length of the missing leg
Answer:
12
Step-by-step explanation:
Using the pythagorean theorem, we know that a^2+ b^2=c^2
In our case, we know b, which is 5 and c which is 13.
If we plug that into the equation, we get a^2+ 5^2 = 13^2
Next, we simplify the equation. a^2 + 25 = 169
Then we subtract 25 from 169. 169 - 25 = 144.
Lastly, we do the square root of 144 and we get 12 which is the missing side.
Answer: 12 miles
Step-by-step explanation:
Use Pythagorean Theorem to find the missing side.
a^2 + 5^2 = 13^2
a^2 + 25 = 169
subtract 25 from both sides
a^2 = 144
take the square root of both sides
a = 12
Which choice is equivalent to the quotient shown here for acceptable values of x?
Answer:
(D)
Step-by-step explanation:
Equivalent expressions are expressions that have equal values
The equivalent expression of [tex]\sqrt{8x^2 } \div \sqrt{3x}[/tex] is [tex]\sqrt{\frac{8x}{3}}[/tex]
The expression is given as:
[tex]\sqrt{8x^2 } \div \sqrt{3x}[/tex]
Represent the expression as a quotient
[tex]\sqrt{8x^2 } \div \sqrt{3x} = \sqrt{\frac{8x^2}{3x}}[/tex]
Evaluate the quotient
[tex]\sqrt{8x^2 } \div \sqrt{3x} = \sqrt{\frac{8x}{3}}[/tex]
Hence, the equivalent expression of [tex]\sqrt{8x^2 } \div \sqrt{3x}[/tex] is [tex]\sqrt{\frac{8x}{3}}[/tex]

Sarkis wants to draw a triangle with sides measuring 4 ft, 10 ft, and 16 ft. Which is true about Sarkis’s plan?
Answer: Sarkis cannot draw a triangle with these side lengths.
Step-by-step explanation: The triangle inequality theorem states that the sum of any two sides of a triangle must be greater than the other side.
The two smallest sides are 4 and 10; their sum is 14. This is shorter than the longest side, so these will not make a triangle.

Brenda is playing hide-and-seek with Cody and Lara. Cody is hiding 16 meters
south of Brenda, and Lara is hiding due east of Cody. If Brenda is 20 meters from
Lara, how far apart are Cody and Lara?
Answer:
36 meters away
Step-by-step explanation:
If you look at the equation you'll see that Cody is 16 meters away from Brenda and Lara is 20 meters away from Brenda, so if you add those two, you'll get the answer. :)
Answer:
i think they are 36 meters apart
Step-by-step explanation:
16 + 20 = 36
so they are 36 meters away from each other
and you could check your answer by doing 36 - 20 = 16 or 36 - 16 = 20

I bought a box from the post office that has a volume of 24 cubic centimeters,
Which of the following could be the dimensions of my box?
A. 8cm long, 1cm wide, 3cm high
B.10cm long, 4cm wide, 10cm high
C. 2cm long, 2cm wide, 6cm high
Answer:
A) Is the answer
Step-by-step explanation:
vol.=LxBxH
8x1x3=24
The dimensions that could be the box with a volume of 24 cubic centimeters are:
8cm long, 1cm wide, 3cm high
2cm long, 2cm wide, 6cm high
Options A and C are the correct answer.
We have,
To determine if the given dimensions could represent the box with a volume of 24 cubic centimeters, calculate the volume for each option and check if it matches the given volume.
Let's calculate the volume for each option:
Option A:
Length = 8 cm, Width = 1 cm, Height = 3 cm
Volume = Length × Width × Height
Volume = 8 cm × 1 cm × 3 cm
Volume = 24 cubic cm
Option A could be the dimensions of the box
Option B:
Length = 10 cm, Width = 4 cm, Height = 10 cm
Volume = Length × Width × Height
Volume = 10 cm × 4 cm × 10 cm
Volume = 400 cubic cm
Option B does not have a volume of 24 cubic cm.
Option C:
Length = 2 cm, Width = 2 cm, Height = 6 cm
Volume = Length × Width × Height
Volume = 2 cm × 2 cm × 6 cm
Volume = 24 cubic cm
Option C could be the dimensions of the box.
Therefore,
The dimensions of the box with a volume of 24 cubic centimeters are:
8cm long, 1cm wide, 3cm high
