Answer:
18cm
Step-by-step explanation:
Given:
- The length of AB is 9 centimeters
- A dilation with a scale factor of 2
The length of the image AB after the dilation is applied:
9 x 2 = 18
dilation is used to make an image or in this case AB, with a scale factor of 2 means that its doubling in size. If the scale factor was 1/2 that it would be decreasing in size since it will be half of the original size
2/4=1/2 and 4/8
1/3=2/6 and 3/9
1/4=2/8 and 3/12
Answer:
.
Step-by-step explanation:
We have been given a geometric sequence 18,12,8,16/3,.. We are asked to find the common ratio of given geometric sequence.
We can find common ratio of geometric sequence by dividing any number by its previous number in the sequence.

Let us use two consecutive numbers of our sequence in above formula.
will be 12 and
will be 18 for our given sequence.

Dividing our numerator and denominator by 6 we will get,

Let us use numbers 8 and 16/3 in above formula.



Therefore, we get
as common ratio of our given geometric sequence.
Answer:
4 :45 pm
Step-by-step explanation:
2 : 20 + 17 minutes = 2:37
2:37 + 1hr 1 minute = 3 : 38
3 : 38 + 1 hr 7 = 4 :45 pm
