In the figure, FQ is parallel to RS". The length of PT is 3 cm; the length of PQ
sasho [114]

Answer:

The measure of length RT is 9 cm  .

Step-by-step explanation:

Given figure as :

The Triangle TRS and Triangle TPQ are similar triangles

I.e Δ TRS ≈ Δ TPQ

And The measure of side PT = 3 cm

The measure of side PQ = 5 cm

The measure of side RS = 15 cm

Let The measure of side RT =  x cm

So,<u> From the property of similar triangles</u>

\dfrac{\textrm measure of side TR}{\textrm measure of side TP} = \dfrac{\textrm measure of side RQ}{\textrm measure of side PQ}

I.e \dfrac{TR}{TP} = \dfrac{RS}{PQ}

Or, \dfrac{x}{3} = \dfrac{15}{5}

Or, \dfrac{x}{3} = 3

∴  x = 3 × 3

I.e x = 9 cm

Hence The measure of length RT is 9 cm  .  Answer

kicyunya [14]
Almons:walnuts:rasins=1:2:3


x=pounds of walnuts
y=pounds of almonds
z=pounds or rasins
2x=y
3x=z
subsitute


12x+9y+5z=15
12x+9(2x)+5(3x)=15
12x+18x+15x=15
45x=15
divide by 45
x=1/3
so
1/3 pound of walnuts
2x=y
2(1/3)=y=2/3
2/3 pounds of almonds
3x=z
3(1/3)=z
1=z
1 pound of rasins




1/3 pound walnuts
2/3 pound almonds
1 pound rasins
