Answer:

z = 66

Step-by-step explanation:

RS = z

QT = z - 33

Based on the midsegment theorem, QT = ½(RS)

Plug in the values

z - 33 = ½(z)

Multiply both sides by 2

2(z - 33) = z

2z - 66 = z

Add 66 to both sides

2z = z + 66

Subtract z from both sides

2z - z = 66

z = 66

slava [35]

Answer:

see explanation

Step-by-step explanation:

1 revolution is equivalent to the circumference of the wheel

1 revolution = πd ( d is the diameter )

                    = 70π cm

50 revolutions = 70π × 50 = 3500π cm = 35π m ≈ 110m ( nearest metre )

Pls Someone help me I don't understand math very well can someone help me on how to get the answer for 1/4 x 8 4/9?
Eduardwww [97]

Answer:

2 4/36

Step-by-step explanation:

To do this, multiply the whole number by the denominator and add it to the numerator.

8 x 9 = 72

72 + 4 = 76

76/9

<em>Then multiply across (multiply numerators with numerators; denominators with denominators)</em>

76 x 1 = 76

9 x 4 = 36

76/36 = 2  4/36

____________________________

<em>A faster way to do this is to multiply the whole number by the fraction and then the fraction by the fraction.</em>

1/4 x 8/1 = 8/4 = 2

1/4 x 4/9 = 4/36

 = 2  4/36
