Tiwa spent 1 1/2 hours setting up her computer. It took her 3 times as long to install the software. How long did it take Tiwa t
MrRissso [65]

Answer:

Total time spent by Tiwa to set up the computer and install software = 6 hours

Step-by-step explanation:

Given:

Time spent by Tiwa to set up  her computer = 1\frac{1}{2}\ hours

Time spent to install the software is 3 times the time she took to set up the computer.

To find the total time Tiwa took to set up her computer and install the software.

Solution:

Time spent by Tiwa to install the software can be given as:

⇒ 3\times 1\frac{1}{2} \ hours

<em>In order to multiply mixed numbers we first change them to fractions.</em>

We multiply the denominator to the whole number and add the numerator to it. Then we write the number as numerator of a fraction with the same denominator.

So, 1\frac{1}{2}=\frac{3}{2}

So, we have:

⇒ 3\times \frac{3}{2}\ hours

⇒ \frac{9}{2}\ hours

Total time spent by Tiwa to set up the computer and install software can be given as:

⇒ \frac{3}{2}\ hours+\frac{9}{2}\ hours

Since denominators are same, so we simply add the numerators.

⇒ \frac{3+9}{2}\ hours

⇒ \frac{12}{2}\ hours

⇒ 6\ hours

vlabodo [156]

Answer:

  QR(3), RS(3), PQ(3), ST(11), RP(6), RT(14), SP(9), QT(17)

Step-by-step explanation:

The diagram is not shown, but we assume the points are in the sequence ...

  P, Q, R, S, T

Since QR = RS, R is apparently the midpoint of QS, So ...

23. QR = 6/2 = 3

24. RS = QR = 3

25. PQ = QR = 3

26. ST = PT -PQ -QS = 20 -3 -6 = 11

27. RP = PQ +QR = 3 +3 = 6

28. RT = RS +ST = 3 +11 = 14

29. SP = PQ +QS = 3 +6 = 9

30. QT = QS +ST = 6 +11 = 17
