Answer:
The scale factor in the dilation of a mathematical object determines how much larger or smaller the image will be (compared to the original object). When the absolute value of the scale factor is greater than one, an expansion occurs. When the absolute value of the scale factor is less than one, a compression occurs.
Step-by-step explanation:
Answer:
bigger angle is 117°
Step-by-step explanation:
x+x+54= 180 (when two angles are complementary it means that their sum is 180 degrees)
2x+54=180
2x= 180-54
2x=128
x=126/2
x= 63
x1= smaller angle
x1= 63
x2= bigger angle
x2= 63+54
x2=117
Answer:
280.5 mm^2
Step-by-step explanation:
scale * 25.5 mm = 127.5 mm 1275/25.5 = 5 scale factor
25.5 * 55/5 = 280.5 mm^2
Answer:
2.10
Step-by-step explanation:
# of large ice creams: 240/3 = 80
# of small ice creams: 240 - 80 = 160
Total large ice cream cost: 80*3.8 = 304
Total small ice cream cost: 640 - 304 = 336
Cost of one small ice cream: 336/160 = 2.1
Answer:
B. False
Step-by-step explanation:
Mass doesn't change when gravitational force changes, but the weight does change.
