if indeed the QT || RS, that simply means that QT is the midsegment of ∡PRS, but that also means that the corresponding sides of the small triangle ∡PQT and the larger one ∡PRS are in a proportion, meaning

$\bf \cfrac{PQ}{PR}=\cfrac{PT}{PS}~\hspace{5em}\cfrac{18}{18+38}=\cfrac{36}{36+80}\implies \cfrac{18}{56}=\cfrac{36}{116}\implies \cfrac{9}{28}\ne \cfrac{9}{29}~~\bigotimes$

How are basic facts can help you find 10*20*30*40 mentally

Lena [83]

When you do the multiplication you can notice that 10, 20, 30, 40 all have 0's at the end.

So that means 10 *20*30*40 = 1*2*3*4*10000 = 24*10000 = 240,000

If the weight of a package is multiplied by 5/7 the result is 40.5 pounds. Find the weight of the package.

ololo11 [35]

Well, it would become 5/7x=40.5. Divide both sides by 5/7, so it is 40.5 * by the reciprocal of 5/7 (7/5). The answer is 56.7 pounds.

Find the domain of the function.

timurjin [86]

When taking square roots, you can't take square roots of negative roots of negative numbers. So, what will work for the domain of u(x) is what makes u(x) zero or more. We can make an inequality for that.

u(x) ≥ 0.

$\sqrt{9x+27} \geq 0$

9x + 27 ≥ 0 by squaring both sides

9x ≥ -27

x ≥ -3

So the domain of the function is when x ≥ -3 is true.
