iren [92.7K]

Answer:6 17/18 hours

Step-by-step explanation:

We are informed that on Monday Katie spent 2 1/6 hours studying while onn Tuesday she spent another 4 7/9 hours studying.

The combined length of time she spent studying will be the addition of the numbers of hours spent studying on Monday and Tuesday. This will be:

= 2 1/6 + 4 7/9

= 2 3/18 + 4 14/18

= 6 17/18

She used a total of 6 17/18 hours studying

The diagonals of rectangle. QRST intersect at P. Given that m&lt;PTS = 34° and QS=10 , find QP.<br>​
Marina86 [1]

Answer:

QP = 5

Step-by-step explanation:

since QRST is a rectangle, and QRST intersect at P, then QTS and QRS are right  triangles.

because <T is a right angle, line TR passes through the midpoint of line QS, therefore 2(QP) = QS

10/2 = 5

Suma doua numere este 702.Diferenta lor este un sfert din scazator .Afla cele doua numere dAU COROANA
Molodets [167]

Answer:

Cele două numere căutate sunt:

  1. <u>390 </u>
  2. <u>312</u>

Step-by-step explanation:

Pentru a rezolva necunoscutul cu aceste două numere, trebuie create două ecuații cu două necunoscute X și Y cu informațiile obținute: În primul rând, știm că suma celor două numere este egală cu 702, prin urmare:

1. <u>X + Y = 702 </u>

Apoi se menționează că diferența (adică scăderea) dintre cele două numere este egală cu un sfert din numărul cel mai mic, pentru a avea o referință, vom identifica variabila Y ca fiind cel mai mic număr, deci a doua ecuație ar fi:

2. <u>X - Y = 0,25Y</u> sau <u>Y / 4 </u>

Ștergem variabila X în a doua ecuație:

  • X - Y = 0,25Y
  • X = 0,25Y + Y
  • <u>X = 1,25Y </u>

Ecuația 1 este acum folosită cu X-ul șters:

  • X + Y = 702
  • 1,25Y + Y = 702
  • 2,25Y = 702
  • Y = 702 / 2,25
  • <u>Y = 312 </u>

Acum, din moment ce se știe că este X = 1.25Y, valoarea lui Y este înlocuită și obținem:

  • X = 1,25Y
  • X = 1,25 * 312
  • <u>X = 390</u>
