Answer: After 4 months they will have the same number of Stamps
Xian and Kai will have 124 stamps each one.
Step-by-step explanation:
60+16x = 76+12x (Subtract 12 from both sides)
-12 -12
60+4x = 76 (Subtract 60 from both sides)
-60 -60
4x/4x = 16/4x (Divide 16 by 4)
X = 4
Answer:
6:9
or 6 to 9
Step-by-step explanation:
Scale factor is defined as a number which multiplies or scales some quantity.
The shape of the figure remains same, the image becomes larger or smaller.
If the scale factor is greater than one, then the image is enlarged.
If the scale factor is less than 1 but greater that 0, then the image becomes smaller.
In the above image, AD = 2 units.
It's corresponding side PS = 3 units
Similarly AB = 1 unit and PQ = 1.5 units
Hence , 1 * 1.5 = 1.5
2*1.5 = 3
Hence, the scale factor of the given image is 1.5 ... Answer
V = (1/4)(π* d² * h)
<span>V = (1/4)(π * 10² * 12) </span>
<span>V = (1/4)(1200π) </span>
<span>V = 300π </span>
<span>[ V ≈ 942 cubic units . . . . . to 3 s.f. ] </span>
<span>V ≈ 942 cubic units
</span>
