using a scale of 1cm to represent 30m find the length of the scale drawing of the following measurement.(a) 130m (b) 72m (c) 150m (d) 200m (e) 118m
try 150
Great
Answer:150 km squared Step-by-step explanation:5*1.5=7.54*5=2
pls help solve it
(a) If 1cm represents 30m, then to find the length of 130m, we can set up a proportion:
1cm/30m = xcm/130m
Cross-multiply and solve for x:
30m * xcm = 1cm * 130m
30x = 130
x = 130/30
x ≈ 4.33cm
So, the length of the scale drawing for 130m is approximately 4.33cm.
(b) Following the same process, we have:
1cm/30m = xcm/72m
Cross-multiplying:
30x = 72
x = 72/30
x = 2.4cm
The length of the scale drawing for 72m is 2.4cm.
(c) Using the same calculations, for 150m we have:
1cm/30m = xcm/150m
30x = 150
x = 150/30
x = 5cm
The length of the scale drawing for 150m is 5cm.
(d) For 200m, we have:
1cm/30m = xcm/200m
30x = 200
x = 200/30
x ≈ 6.67cm
The length of the scale drawing for 200m is approximately 6.67cm.
(e) Lastly, for 118m:
1cm/30m = xcm/118m
30x = 118
x = 118/30
x ≈ 3.93cm
The length of the scale drawing for 118m is approximately 3.93cm.
To find the length of the scale drawing, you need to multiply the actual measurement by the scale factor. In this case, the scale factor is 1cm represents 30m.
(a) 130m:
To find the length of the scale drawing for 130m, multiply 130 by the scale factor: 130m * 1cm/30m = 4.33cm
(b) 72m:
To find the length of the scale drawing for 72m, multiply 72 by the scale factor: 72m * 1cm/30m = 2.4cm
(c) 150m:
To find the length of the scale drawing for 150m, multiply 150 by the scale factor: 150m * 1cm/30m = 5cm
(d) 200m:
To find the length of the scale drawing for 200m, multiply 200 by the scale factor: 200m * 1cm/30m = 6.67cm
(e) 118m:
To find the length of the scale drawing for 118m, multiply 118 by the scale factor: 118m * 1cm/30m = 3.93cm
So, the length of the scale drawing for each measurement is:
(a) 130m: 4.33cm
(b) 72m: 2.4cm
(c) 150m: 5cm
(d) 200m: 6.67cm
(e) 118m: 3.93cm
