What does it mean when you have ratio and it says explain the meaning??

Yukio says the scale from DEF to ABC is 3:1. Is Yukio Correct? Explain

Angelina_Jolie [31]

Answer: Yes, Yukio is correct.

Step-by-step explanation:

Assuming that Triangle DEF and ABC have the same angles (they do because they are right-angled), we can take the length from the larger triangle (DEF) and divide it by the length of the smaller triangle (ABC).

Length of DEF = 6cm

Length of ABC = 2cm

= 6/2

= 3

Proves that scale of DEF to ABC is 3:1

Can yah help me with those two question please :(

Maurinko [17]

Solution 1 :-

Statement : corresponding angles in similar triangles must be congruent .

Answer : True

Solution 2 :-

Statement : The hypotenuse of a right angle triangle has to be opposite of 90 degree .

Answer : True

Reason : We know that the side opposite to largest angle in a triangle is largest . Since in a right angle triangle 90 degree is the largest angle and hypotenuse is the longest side therefore they must be opposite to each other .

Two vertical poles of lengths 11 ft and 14 ft stand 16 ft apart. A cable reaches from the top of one pole to some point on the g

Alex17521 [72]

We are given

total length of cable is 30 feet

and this cable is on hypotenuse sides of the triangles

so, we can draw triangle as

Let's assume those hypotenuse as 'a' and 'b'

so, we will have

$a+b=30$

now, we can find 'a' and 'b' from triangle

Smaller triangle:

$a=\sqrt{x^2+11^2}$

Larger triangle:

$b=\sqrt{(16-x)^2+14^2}$

we know that

$a+b=30$

so, we can plug this value

and we get

$\sqrt{x^2+11^2}+\sqrt{(16-x)^2+14^2} =30$

now, we can solve for x

$\left(\sqrt{x^2+11^2}\right)^2=\left(30-\sqrt{\left(16-x\right)^2+14^2}\right)^2$

$32x-1231=-60\sqrt{x^2-32x+452}$

$1024x^2-78784x+1515361=3600x^2-115200x+1627200$

now, we can use quadratic formula

we get

$x=\frac{-\sqrt{36416^2-1152389056}+36416}{5152},\:x=\frac{\sqrt{36416^2-1152389056}+36416}{5152}$

$x=4.510,x=9.627$

so,

The point should be located 4.510 feet , 9.627 feet from the smaller pole to use 30 feet cable............Answer

Hey, heres some homework I have no idea on.

Tems11 [23]

First, let’s start off by removing the two that don’t a a brother or sister. That leaves 10 people who do. The we calculate the access answers. They go in the middle. It’s 6. Then we have one more that has only a sister, put that at the S side. Then we have 3 more left that have only a brother, put them on the B side. Then you have 10 dots on the diagram for the 10 peoples that have a brother and/or a sister.

To conclude:
3 on B
6 in between
1 on S
