The ratio that comes next in the sequence is 8:23.
<h3 /><h3>Definition of a ratio</h3>
Ratio expresses the relationship between two or more numbers. It shows the frequency with which one value is contained in another value.
<h3 /><h3>How to determine the numbers that come next</h3>
Looking at the first ratio in the sequence, the number on the left increases by 1 in the second ratio. In the second ratio, the number on the left increases by 2 and for the third ratio. The difference between the third and fourth ratio is 1 for the number on the left. This shows that the sequence for the numbers on the left is 1, 2, 1. Thus the next number would increase by 2.
Looking at the first ratio in the sequence, the number on the right increases by 4 in the third ratio. In the fourth ratio, the number on the right increases by 4 when compared with the third ratio. This shows that the sequence for the numbers on the right is an increase by 4.

Answer:
40
Step-by-step explanation:
6 of 30 is the ratio 6 to 30 or 6/30.
6/30 reduces to 1/5
The survey shows that 1/5 of the students attend summer camp.
1/5 of 200 = 1/5 * 200 = 40

Answer:
see explanation
Step-by-step explanation:
A geometric progression has a common ratio r between consecutive terms
That is each term in the sequence is obtained by multiplying the previous term by r
Consider 4, 8, 16, 32
4 × 2 = 8
8 × 2 = 16
16 × 2 = 32
This is a geometric progression with r = 2
Consider 3, 6, 9, 12
3 × 2 = 6
6 × 2 = 12 ≠ 9
This is not a geometric progression
Consider 2, 6, 18, 54
2 × 3 = 6
6 × 3 = 18
18 × 3 = 54
This is a geometric progression with r = 3
Consider 1, 5, 12, 125
1 × 5 = 5
5 × 5 = 25 ≠ 12
This is not a geometric progression
Step-by-step explanation:
$20/hr carpenter pay
$25/hr blacksmith pay
Let c = hours working carpentry
Let b = hours working as blacksmith
c + b = 30 {equation 1}
20c + 25b = 690 {equation 2}
In equation 1 solve for one variable in terms of the other.
c = 30-b
Substitute that into equation 2:
20(30-b) + 25b = 690
600 - 20b + 25b = 690
5b = 90
b = 90/5
b = 18 hours working as a blacksmith
c = 30-b = 30-18 = 12 hours as a carpenter
