Answer:
n = 5 terms
Step-by-step explanation:
An = a1 + (n-1)d
9 = 3 + (n-1) 3/2
9 = 3 + 3/2n - 3/2
9 = 3/2 + 3/2n
9 - 3/2 = 3/2n
(15/2) / (3/2) = n
30/6 = n
Answer:
52 measures
Step-by-step explanation:
With 4 beats per measure, and 208 beats per minute all we need to do here is divide 208 by 4 to get 52.
The total amount that was raised for charity is £75.
<h3>What is the total amount raised?</h3>
Here is the sample space
1 2 3 4 5 6
Heads 1 4 9 16 25 36
Tails 1 8 27 64 125 216
Probability of getting a number greater than 30 = 4/12 = 1/3
1/3 x 450 = 150
Total value of people getting more than 30 : 150 x £1 = £150
Total amount paid = 50 x 450 = £225
Amount raised = £225 - 150 = £75

So it is 5cm to 1m or 5cm to 1000cm
So the scale is the ratio which is 5:1000. this can be reduced to 1:200
10. if the room is 15cm on one side I can say that the ratio to actual size is 15/x. and scale is 1/200 so:
15/x = 1/200
3000 = x is one side
other side:
20/x = 1/200
4000 = x
