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

The relationship between women’s whole-number shoe sizes and foot lengths is an arithmetic sequence, where an is the foot length

ad-work [718]

Answer:

The explicit formula for Arithmetic Sequence is $a_n=7.02+0.33n$

Step-by-step explanation:

Given: Foot length & shoe size in AP.

$a_n$ is foot length and n is shoe size.i.e., $a_{12}=11\:and\:a_7=9.33$

To find: Formula for Arithmetic sequence .i.e., $a_n$

From question,

$a_{12}-a_7=11-9.33=1.67$

Also, we know that

$a_{12}=a_7+5d\\5d=a_{12}-a_7\\5d=1.67\\d=\frac{1.67}{5}\\\\d=0.33$

Now, consider

$a_7=a_1+6d\\a_7=a+6d\\a=a_7-6d\\a=9.33-6\times0.33\\a=9.33-1.98\\a=7.35$

Thus using formula of $a_n$ we get,

$a_n=a+(n-1)d\\a_n=7.35+(n-1)\times0.33\\a_n=7.35+0.33n-0.33\\a_n=7.02+0.33n$

Therefore, The explicit formula for Arithmetic Sequence is $a_n=7.02+0.33n$
