Answer:
A) 1/45
B) 1/60
Step-by-step explanation:
<u>Part A</u>
The actual car has a length to width ratio of ...
length/width = (570 cm)/(180 cm) = 57/18 = 3 1/6
The rectangle on the screen has a length to width ratio of ...
length/width = (13 cm)/(4 cm) = 3 1/4
Relative to its width, the screen rectangle is longer than necessary for a model of the car. So, the scale factor will be determined by the width of the car relative to the width of the screen model.
For a model width of 4 cm, the scale factor is ...
model/life-size = (4 cm)/(180 cm) = 1/45
__
<u>Part B</u>
For a model width of 3 cm, the scale factor is ...
model/life-size = (3 cm)/(180 cm) = 1/60
(3x+4) (2x-6)
6x-18x+4x-24
6x^{2} -14-24
Answer:
(a) 0.2707
(b) 0.8576
Step-by-step explanation:
Answer:
16
Step-by-step explanation:
The differnce of 28 and 12 is 16 because, 28-12=16 and 16+12=28
So the its basically 7x24 and 7x24 is 168. Hope this helped
