Answer:
12:15 is NOT proportional to 3:4
Step-by-step explanation:
7.5:10 is proportional to 3:4 because 3×2.5=7.5, and 4×2.5=10.
39:52 is proportional to 3:4 because 3×13=39, and 4×13=52
45:60 is proportional to 3:4 because 3x15=45, and 4×15=60
12:15 is not proportional to 3:4 because while you can multiply 3x4=12, you can not multiply 4×4 to get 15, you get 16 instead.
the answer to your question is D.12:15

Step-by-step explanation:
A Dilation is defined as a transformation in which the image and the pre-image have the same shape, but their sizes are different.
When the scale factor is greater than 1, the image obtained after the dilation is greater than the pre-image and it is an "Enlargement".
When the scale factor is is between 0 and 1, the image obtained after the dilation is smaller than the pre-image and it is an "Reduction".
In this case you know that the triangle ABC was dilated by this scale factor:
With the origin as the center of dilation.
Since:
It is a Reduction.
You can identify that the vertices of the triangle ABC are:
So you need to multiply the coordinates of each vertex of the triangle ABC by , in order to get the coordinates of the triangle A'B'C. Then, you get:

Answers
Answer:
yes, this quadrilateral is a parallelogram.
Step-by-step explanation:
Above quadrilateral ,
opposite angle 70=70
and there is also 180-70=110 (linear pair)
so, others opposite angle 110=110
This quadrilateral have opposite sides equal
so, this is parallelogram.

Answers
Answer:
x= 25.5 not rounded x=25.51393657
Step-by-step explanation:
Decide what trig ration you need/want to use. The 27 degrees are opposite of the 13 and adjacent to the x which means your ratio should be o/a or 13/x. The trig ratio needed is Tangent. Now you can write the equation as tan(27)=13/x and start solving.
tan(27)=13/x multiply the x on both sides and you'll have x * tan(27)=13 and decide which to put into your calculator and you'll get x=25.51393657 rounded as 25.5

A 50 foot ladder is set against the side of a house so that it reaches up 30 feet. If Alonso grabs the ladder at its base and pulls it 5 feet farther from the house, how far up the side of the house will the ladder reach now? (The answer is not 25 ft.) Round to the nearest tenth of a foot.
Answers
Answer:
21.8
Step-by-step explanation:
The distance for the side of the house will the ladder reach now should be considered as the 21.8 ft.
Calculation of the distance;Since first we have to determine BC i.e.
[tex]= \sqrt{50^2 - 30^2} \\\\= \sqrt{1600}[/tex]
= 40 ft
Now
In the case when Alonso grabs the ladder at its base and pulls it 5 feet farther from the house
So,
[tex]= \sqrt{(50)^2 - (45)^2} \\\\= \sqrt{475} \\\\= 5 \sqrt 19[/tex]
= 21.8 ft.

Step-by-step explanation:
The given expression is :
[tex]\dfrac{2-\sqrt5}{2+3\sqrt5}=\sqrt5 x+y[/tex] ....(1)
Taking LHS of the above expression
[tex]\dfrac{2-\sqrt5}{2+3\sqrt5}[/tex]
Rationalizing both denominator and numerator.
[tex]\dfrac{2-\sqrt5}{2+3\sqrt5}\times \dfrac{2-3\sqrt5}{2-3\sqrt5}=\dfrac{4-6\sqrt5-2\sqrt5+15}{2^2-(3\sqrt5)^2}\\\\=\dfrac{19-8\sqrt5}{4-45}\\\\=\dfrac{19-8\sqrt5}{-41}\\\\=\dfrac{\sqrt5 \times 8}{41}+(\dfrac{-19}{41})[/tex]
Equation (1) becomes,
[tex]\dfrac{\sqrt5 \times 8}{41}+(\dfrac{-19}{41})=\sqrt 5\ x+y[/tex]
Equating both sides,
[tex]x=\dfrac{8}{41}[/tex] and [tex]y=\dfrac{-19}{41}[/tex]
Hence, this is the required solution.

210 is what percent of 500?
Answers
Answer:
42
hope this answer helps you!
Explanation:
Step 1: We make the assumption that 500 is 100% since it is our output value.
Step 2: We next represent the value we seek with X.
Step 3: From step 1, it follows that 100%= 500.
Step 4: In the same vein, X%= 210.
Step 5: This gives us a pair of simple equations:
100%= 500(1)
X%=210(2)
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have
100%/X%= 500/210
Step 7: Taking the inverse (or reciprocal) of sides yields
X%/100= 210/500
X= 42%
