Answer 1
Answer:

Answer:

2 square units

Step-by-step explanation:

hello

The scale factor or linear scale factor is the ratio between the length of the same side in two similar figures.

in the graph we have  a rectangle with width 5 units and long 10 units, and we know the scale factor is 1/5

S_(f)=(width(C))/(width(B))\n \nWidth(B)*S_(f) =width(C)=5 units *(1)/(5) \n\nWidth(C) =(5)/(5) units =1 unit

S_(f) =(length (C))/(length(B)) \n\n\nlength(C)=length(B)*S_(f)\nlength(C)=(10*(1)/(5))

Length(C) =2 units\n\n the area is A=w*l\n\nA=1 unit * 2 units\n\n\n

A=2 square units

I hope it helps
Answer 2
Answer:

Answer:

The area of rectangle C is 2

Step-by-step explanation:

Using a scale factor of (1)/(5) yields the side lengths of 1 and 2

(1)(2)=2

Answer:

x=10

Step-by-step explanation:

In order to solve this equation we must break it down. This question is going to require the Pythagorean theorem a^(2) +b^(2)=c^(2). To use this we need a right triangle which happens to be half of the triangle shown. Now we can plug in the numbers.

7^(2)+(1)/(2) x^(2) =√(74)^(2)

49+(1)/(2) x^(2) =74

(1)/(2) x^(2) =25

(1)/(2) x=5

x=10

This ends in x equaling 10. I hope this helps you!

Will choose brainiest answer!!! plz help!! <3 <3 Are x and y proportional? y = 5.7x Explain your answer

Answers

alrighty

first make a table.

x       y

0       0

1       5.7

2       11.4

so on anso forth

yes this is proportional.    what grade are you in? I want to teach u something to make it easy
since 5.7 is a constant, lets concider it equal to K & put it aside for a moment.
now, there is an (=) sign between x & y this means there is a proportionality relation between x & y. now if we reconcider the constant, it becomes y=Kx. it means tha y is equal to K times x i.e. if we write x K times, it'll be equal to y. now we know that if we remove constants form an equation, we can relate proportionality there.... so lets remove constants;
this implies y is proportional to x.
Hope it helps.
