Answer:
should have 3.5 for the first one ::))
Step-by-step explanation:
First you need to determine which type of sequence is this. Because the difference between 2 successive numbers is constant and it is equal to 10 this sequence is geometric one.
d = 10
To calculate what is the value of some member of this sequence you use formula:
An = Ao + (n-1)*d
where n represents position of element An, Ao is value of first element in the sequence.
Replacing values we get:
A110 = -7 + 109*10
A110 = 1083.
It would be -13 because 4 times -1 is -4 minus 9

Answer:
<h2>5 cm</h2>
Step-by-step explanation:
step one:
Given that the scale of the map is
2cm to represent 30 miles
That is every 1 cm is 15 miles in reality
step one:
what we are solving for is the distance in cm on the map so,
1cm rep 15miles
xcm rep 75miles
cross multiply
Xcm= 75/15
X= 5 cm
hence on the map 75miles distance between the two towns is seen as 5 cm
