Calculate The scale factor of XYZ to you UVW enter answers as a whole number as a fraction in lowest terms using the slash mark

Lelu [443]

Answer:

Scale factor of ΔXYZ to ΔUVW will be 1/5

Step-by-step explanation:

Since all the angles of ΔXYZ and ΔUVW are equal, both the triangles will be similar.

ΔXYZ ~ ΔUVW

Since both the triangles are similar, ratio of the corresponding sides will be in the same ratio.

$\frac{UV}{XY}=\frac{VW}{YZ}=\frac{UW}{XZ}$

And the scale factor = $\frac{\text{Side of UVW}}{\text{Side of XYZ}}$

= $\frac{UV}{XY}$

= $\frac{12}{60}$

= $\frac{1}{5}$

Therefore, scale factor of ΔXYZ to ΔUVW will be 1/5

The park charges 1.50 per ride.

1. Louisa bought 15 ride tickets at 1.50 each.

Equation: C = Entry Fee + 1.50t

t = 15.

c = 30.75

30.75 = Entry Fee + 1.50(15)

30.75 = Entry fee + 22.50

Entry fee = 30.75 - 22.50

Entry fee = $8.25

2. Entry fee was calculated as 8.25 from #1.

Tickets are 1.50 each.

He can spend 22.

22 = 8.25 + 1.50t

Subtract 8.25 from both sides:

13.75 = 1.50t

Divide both sides by 1.50:

t = 13.75 / 1.50

t = 9.2

He can buy 9 tickets.

The distance from the centroid of a triangle to its vertices are 16cm, 17cm, and 18cm. What is the length of the shortest median

Marizza181 [45]

Answer:

$24$ $\text{cm}$

Step-by-step explanation:

Given: The distance from the centroid of a triangle to its vertices are $16\text{cm}$ , $17\text{cm}$ , and $18\text{cm}$ .

To Find: Length of shortest median.

Solution:

Consider the figure attached

A centroid is an intersection point of medians of a triangle.

Also,

A centroid divides a median in a ratio of 2:1.

Let G be the centroid, and vertices are A,B and C.

length of $\text{AG}$ $=16\text{cm}$

length of $\text{BG}$ $=17\text{cm}$

length of $\text{CG}$ $=18\text{cm}$

as centrod divides median in ratio of $2:1$

length of $\text{AD}$ $=\frac{3}{2}\text{AG}$

$=\frac{3}{2}\times16$

$=24\text{cm}$

length of $\text{BE}$ $=\frac{3}{2}\text{BG}$

$=\frac{3}{2}\times17$

$=\frac{51}{2}\text{cm}$

length of $\text{CF}$ $=\frac{3}{2}\text{CG}$

$=\frac{3}{2}\times18$

$=27\text{cm}$

Hence the shortest median is $\text{AD}$ of length $24\text{cm}$
