Answer: The scale factor of ABC to DEF is 5.

Step-by-step explanation:

Knowing that the side ratios are the same because the triangles are similar, you can use ratios to solve for x and y.

Side AB and Side DE are similar. The former has a length of 3 and the latter has a length of 15, which means that the triangle on the right is 5 times larger than the triangle on the left.

Using this information, you can solve for x by dividing 38.5 by 5.

X = 7.7.

You can then multiply 8 by 5 to solve for y, so y = 40.

X = 7.7, y = 40.

Scale factor is 5.

When constructing an angle bisector, why must the arcs intersect?

<span>The arcs must intersect because the point at which the arcs intersect forms the halfway point of the angle; if they don’t intersect, the angle will not be bisected. </span>

A set of five distinct positive integers has a mean of $1000$ and a median of $100$. What is the largest possible integer that c
mixer [17]

Answer:

e = 4796

Step-by-step explanation:

given,

mean of five distinct positive number = 1000

median of the number = 100

100 is median means two number will be less than 100 and two number will be greater than 100.

let five number be

a , b, c, d, e

'e' should be the largest number

As 100 is median so 'c' = 100.

'a' and 'b' should be as small as possible and d should be the number nearest to 100.

As all the number are distinct so the least number be equal to 1 and 2

now d will be equal to 101 (nearest to 100)

now,

sum of the five number = 5 x 1000 = 5000

a + b + c + d + e = 5000

1 + 2 + 100 + 101 + e = 5000

e = 5000 - 204

e = 4796

hence, the largest number will be equal to e = 4796
