The quadrilateral shown is a rectangle. What is the measure of PR? (round to the nearest hundredth)
sladkih [1.3K]

Option B) 37.12 is the right answer

Step-by-step explanation:

It is given that the qudrilateral is a rectangle which means that opposite sides wil be equal and all interior angles will be 90 degrees

So

PS = 17

PQ = SR = 33

The diagonal PR will form a right-angles triangle with PR being the hypotenuse

So,

Base = SR = 33

Perpendicular = PS = 17

Hypotenuse = PR = ?

The Pythagoras theorem will be used to find the length of PR

So,

H^2 = B^2+P^2\\(PR)^2 = (SR)^2 + (PS)^2\\PR^2 = (33)^2+(17)^2\\PR^2 = 1089+289\\PR^2 = 1378\\

Taking square root on both sides

\sqrt{PR^2} = \sqrt{1378}\\PR = 37.1214

Rounding off to nearest 100th

PR = 37.12

Hence,

Option B) 37.12 is the right answer

Joel wants to buy a new tablet computer from a store having a 20% off sale on all tablets. The tablet he wants has an original c
gtnhenbr [62]

Answer:

190 *.80 *(1.05)

<em> Instead of adding the sales tax, he subtracted the sales tax. </em>

159.60

Step-by-step explanation:

If Joel gets 20% off, he still has to pay (100-20) or 80%

The cost of the tablet is now 190 * .80

Then he has to pay 5% sales tax.

The tax is the prices times 5%   plus the original price

190 *.80 *(1+.05)

or 190 *.80 *(1.05)

Instead of adding the sales tax, he subtracted the sales tax.

The total he needs to pay is

190 *.80 *(1.05)

159.60

Hope this helps :)
